Simple Narration Of Biology(II)

Subject Classification

Bio-taxonomy is a branch of biology that studies the methods and principles of biological taxonomy. Classification follows the principles and methods of taxonomy, naming and grading various groups of organisms. Carl von Linné ( Carl Linnaeus), a Swedish biologist, named the organism, and then the biologists classified it by Domain, Kingdom, Phylum, Class, Order, Family, Genus and Species.Steel Pipe Suppliers

At the top level of kingdom, the five Kingdoms proposed by Robert Whittaker, is accepted by many people. These five Kingdoms respectively are Kingdom Monera, Protista, Plantae, Fungi or Animalia. From the top level of “Kingdom” to the lowest level of “species”, the closer characteristics of the attributable organisms will show out when reach to the lower level.

Main Course

It is mainly about the observation and description of nature. It is about the study of natural history and morphological classification. So biology was first classified by taxa, such as botany, zoology, Microbiology and so on.

Because of the diversity of biological species, and also because people have more and more knowledge of biology, the division of disciplines is becoming more and more detailed, and a discipline is often subdivided into several disciplines.

For example, Botany can be divided into algology (phycology), bryology (muscology), pteridology; Zoology may divide into protozoology, entomology (insectology), ichthyology, ornithology, etc; Microorganisms are not a natural group of organisms, but an artificial division, all tiny organisms such as bacteria and single-cell fungi, algae, protozoa all can be called microorganisms, and viruses without cellular form can also be included in microorganism.

Therefore, microbiology can be further divided into bacteriology, mycology, virology and so on.

The division of disciplines according to biological groups is conducive to understand the biological characteristics and regularity of a natural group from all aspects. However, no matter what the specific object is, the research topics are nothing more than the classification such as morphology, physiology, biochemistry, ecology, heredity, evolution and so on.

Amazing Natural World(II)

The water temperature in the U.S. Death Valley is not suitable for the survival and reproduction of Death Valley pupfish. Plasticity also has genetic basis, which is determined by the chromosome set and living environment of individual organisms. A new direction of adaptive evolution depends on the variability of organisms themselves, which together depends on the phenotypic plasticity of genotype and structure, physiology and behavior. It is an endangered fish species, whose survival depends entirely on the environment. Rare water resources in deserts are essential for its survival.

Inhabitation environment

The Devils Hole, 96 kilometers east of the U.S. Death Valley, chick is the only natural habitat for Death Valley pupfish. Geologists estimate that the depth of the cave (Devils Hole) is at least 130 meters and has been formed for 500 thousand years. These fish come to this cave for no more than 50 thousand years. 50 thousand years ago it was probably an earthquake, and the top of the cave collapsed, exposing it and the water inside. The water in the Devil Hole is hypoxic and maintains temperatures ranging from 33.3 to 33.9 degrees Celsius, which is the upper limit most fish can tolerate. The behavior of Death Valley pupfish depends on the environment of its habitat. Over-dependence on the only habitat will make the Death Valley pupfish of Devil Hole to extinct easily. For this reason, three shelters imitating the environment of Devil Hole have been built. 5 years later, the phenotype of the Death Valley pupfish in the refuges were quite different from those in the Devil Hole.

Common Problems in Pipe Welding and their Remedies

Many engineers always have certain problems when welding pipes. Whether or not it’s approximately welding high-strain pipe, high purity pipe for meals and beverage industries, or pipe for the oil and gasoline industries, there are a number of not unusual elements we see in pipe welding and fabrication that result in troubles. these encompass the entirety from fallacious shielding gas and pressure rolls to choosing a MIG gun with too low of an amperage score. As companies push to train new welders, work with new materials, increase pleasant and productivity, and improve safety, it’s far important to attention on a number of these simple variables inside the pipe welding system that can affect these efforts. We shall be looking at some of the problems that welded steel pipe engineers and artisans go through and how this can be solved or made clear.

  • Cutting corners with cutting

While welders work with substances more vulnerable to distortion and the influences of higher warmness input, consisting of stainless steel and aluminum, a terrible cut can result in bad healthy-up and create pointless gaps. Welders then compensate by way of placing more filler metal (as a result, warmness) into the joint to fill it. This introduced warmness can cause distortion and, with corrosion-resistant pipe like chrome steel, can lessen the corrosion-resistant qualities of the base metal. it may also lead to lack of penetration or immoderate penetration. negative preparation also results in longer weld cycle times, higher consumable costs and capability maintenance.

Use of chop saws or band saws to reduce pipe used in important technique piping packages need to consider shopping for committed orbital pipe reducing gadget to guarantee cuts within mere thousandths of an inch of the required parameters. This precision enables ensure premier in shape-up and continues the quantity of filler and warmth positioned into the joint at a minimal.

  • Forgetting to cut out and feather tacks

Tacking is critical to match-up, and high-quality practices recommend that the welder reduce out and feather that tack to make certain the consistency of the final weld. particularly in stores in which a more healthy prepares the pipe after which someone else welds it, it’s important that the welder is aware of just what’s inside the weld. Tacks left within the joint grow to be ate up through the weld. If there’s a disorder within the tack, or if the more healthy used the incorrect filler metallic to tack the joint, there is a danger for defects within the weld. cutting out and feathering the tacks allows put off this capability trouble.
four. preparing a joint for MIG methods is distinct than with Stick welding education for welders is a top precedence for many fab shops, and — for higher or worse — many welders deliver past stories with them to the new process. those reviews can be addressed with good enough education, but one common mistake we see is welders with Stick revel in no longer information how to correctly put together a joint for cord methods not unusual in pipe fabrication applications. Welders educated traditionally in Stick and TIG welding often prepare the joint with a heavy landing vicinity and want to preserve the space as narrow as viable. As pipe stores transfer over to simpler, more productive MIG approaches including Regulated metallic Deposition (RMD™), we opt for welders take that landing location all the way down to a knife’s side and space the joint at approximately 1/8-inch. This place is wider than the ones skilled in Stick and TIG processes are used to and might lead to a number of problems: focusing an excessive amount of heat into the rims of the weld, a lack of penetration and insufficient reinforcement at the inner of the pipe. shops must train their welders to the specifics of every utility and make certain they recognize specific weld preparation and operational strategies earlier than they visit paintings.

  • Purchase blended gasoline – don’t rely upon mixing with flow regulators

we have visible shops that, for a stainless steel utility that requires 75/25 percentage argon/helium, installation a separate tank of argon and a separate tank of helium and then depend upon go with the flow regulators to bleed in the right quantity of protective fuel. The fact is you definitely don’t recognise what you’re getting in a combination with this technique. shopping for cylinders of mixed gasoline from dependable assets, or shopping for a right mixer, will ensure you understand exactly what you’re defensive your weld with and that you’re adhering to proper weld approaches/qualifications.

  • Incorrect nozzle length can reason troubles

one-of-a-kind sizes and kinds of nozzles are required with one of a kind MIG tactics. for example, we recommend a tapered nozzle with the RMD process to be had on our PipeWorx welding gadget. That identical tapered nozzle, but, can’t accommodate the fuel float necessities of the Pulsed MIG procedure and could cause flawed gas coverage of the weld. understand which nozzles in shape up with each procedure/variable and use as a result.

  • Welding power assets don’t reason porosity

It isn’t always uncommon to get a name from a purchaser.We tell welders to recount their steps lower back from the point where the porosity started. Welders will frequently find that it started out simply when a gas cylinder became changed (loose connections, wrong fuel used), a new twine spool turned into put in, while someone didn’t prep the material well (oxides gift in the weld), or if the material changed into infected elsewhere along the line. maximum of the time the hassle is due to an interruption or hassle with the fuel go with the flow. Tracing returned your steps will regularly result in the variable that precipitated the porosity.
eight. incorrect kind or size of drive roll

Flux-cored wires should be used with a knurled power roll at the same time as stable wires need to be used with a popular V drive roll. it is important that welders bear in mind to change those out as they trade sorts of wires of their gadget. Welders who incorrectly use a preferred V power roll with flux-cored twine will normally word the twine slipping and then crank down at the drive roll anxiety to preserve it in vicinity, which then crushes the cored wire. Knurled pressure rolls will chip off the outer coating on strong wires and that results in plugging up the liner. Welders then have a tendency to crank at the tension and the problems gets worse.

bottom line: if you locate yourself having to crank on the wire tension, it’s miles a symptom of some thing else wrong with the technique: wrong force roll, wrong force roll size or clogging in the liner. work the procedure, make sure you’re the use of the proper force rolls, and you’ll probable locate the reason of your problem.
nine. Do now not add cleaning solvent or lubrication in your dirt pad a few stores will add a dust pad — a small piece of cloth — simply previous to the drive roll gadget so as to eliminate any final contaminants from the cord. This, on  its very own, is exceptional, however we’ve seen a few shops upload a lubricant or cleaning solvent to this pad on the way to similarly improve feeding or “clean” the cord. It has the alternative effect: those oils certainly contaminate the cord and might cause weld defects. As an alternative or for brought protection, you can additionally upload a spool cover to shield the spool of wire from airborne contaminants.

Each the oxyfuel and plasma cutting methods add a layer of oxide to the cut aspect. This oxide layer have to be removed prior to welding, as the oxide regularly has a higher melting point than the bottom metal. as soon as the arc receives hot sufficient to melt the oxide, it’s too hot for the base metal and may cause burn through. The oxides can also remain within the weld and purpose porosity, inclusions, lack of fusion and other defects. it’s far crucial that welders remember to grind the joint right down to the figure fabric prior to welding, as well as grind the inside and outside diameters of the pipe to dispose of those oxides and other capability contaminants.

Highly-Automated Austrian Steel Mill Only Needs 14 People

According to this topic Highly Automated Austrian Steel Mill, we should image how splendid about he automated equipment to operate in the mill, workshops and plants. So what is automated? Before this discussion of topic, let us know about definition of automate deeply. By dictionary explanation Automation is the creation of technology and its applications to control and monitor the production and delivery of a wide range of goods and services. It performs tasks previously performed by humans. Automation is being used in many domains, like more recently information technology, manufacturing, transportation, utilities, defense, facilities, operations.

Actually the dictionary means automation may be performed in many ways in variety of industries. For instance, In the field of information technology, software scripts can test software products and generate reports. There are also a variety of software tools on the market that can generate code for the applications. Users only need to configure the tool and define the process. In other industries, automation has greatly increased productivity, reducing costs and saving time. Automation is rapidly evolving, and business intelligence in applications is a new form of high-quality automation namely highly-Automated. In the field of technology, the impact of automation is rapidly increasing at the software/hardware and machine layers. However, despite the advances in automation, it is always recommended to do some manual intervention, even if the tool can perform most of the tasks. Certainly, now we are perfecting the automation across the different domains and industries and in the not far future, automation will involve in more industries and can be efficiently applied to instead of manual intervention. Actually, Austrian Steel Mill already realized it as well.

Like the coal industry, the steel industry has experienced rapid changes over the past decade. There is no doubt that steel will continue to be an important part of the daily lives of many people, but the question remains whether these people will be involved in the manufacture of this steel? There is a report shows that a plant needs only 14 employees to make almost 500,000 tons of mass quantities steel wire per year.

In the 1930s the village of Leoben has long been an industrial suburb of Vienna, and since the 15th century, the region has been smelting iron. The new factory from the German manufacturer Voestalpine was called “Voestalpine Stahl Donawitz” to commemorate the early community in the area, which was incorporated into Leoben. The plant is so big with a 2,297-foot production line however there is almost nobody there. At most, 3 of technicians monitored the output through computer’s screen. Former lineworkers, these three technicians spent about 3 months to study new technology, leaning about control systems, interpret the rush of data and so on. All of these is about progress during highly automation plan and these three people have to adapt new roles at the plants. So other 11 employees maintaining equipment and retooling the plant for various wire gauges finally consisted of a team.

The two companies have incorporated the concepts of nationalism and history into their marketing, and the steel industry has had similar effects. The factory in the area, formerly known as Donawitz,

employs 1,000 people and the name of the place employs 20 people. Some people doubt that President Trump used steel as his first protectionist trade position as president. But if the experience of Leoben and Donawitz shows anything, it is that the industry has changed radically and will not be the main employer of the past.

New Technology Slashing the Cost of steel production

By this time let us talk about how to reduce the cost of producing steel. Actually we may think about some methods according to rational management and advanced operations in producing industry such as steel production. Referring to development of steel industry, the most of big companies and giant of steel have collected and developed good methods for lowering its steel. Let us list below as summaries,

Allows outsourcing

Outsourcing is another feature of today’s modern enterprise due to the World Wide Web (WWW). Instead of hiring people to get the job done in your factory, you can simply outsource work to the contractor. Contractors can reduce production costs. Companies can outsource small jobs to other countries to save even more.

Lowers energy cost

Green and efficient technology is needed now. And there needs to be good reasons. It does the same amount of work for the business, but it also saves the environment in the process. In return, it saves the company money.

Lowers errors during producing

Manufacturing costs should not only be related to the finished product. If the product has a problem, this is also your responsibility. You will have to deal with the repair costs, not to mention returning customers. So with new technology, you can reduce errors during producing. In fact, it can reduce the number of products returned to your company. It also satisfies customers and enhances the company’s overall reputation.

Productivity monitoring

It is equivalent to the producing process. It is also crucial for lowering cost if we pay attention to this link as productivity monitoring. New technologies can help companies check if their production processes are lagging behind. If there is an area that needs improvement, it is easier to provide corrections and adjustments.

Reduce the need of manpower

Actually mass of manpower and work forces will make company to burden more cost, certainly if be needed, work forces could help finish more jobs. However, if we adopt new technology to give company a chance to operate with less number of employees but with high efficiency. For example, if you look at a car company, they are mainly built with the help of a machine, and only a few technicians are on standby to monitor the machine for problems.

Well, new technology may help us to reduce cost, mentioned above almost these five methods needs to adopt new technology, integrating new technology to gain what we demand such as slashing the cost of steel production. I will offer you exact new technology to prove this point.

Steelmakers are cautious about new technologies. It was not until the 1960s that the industry began to cast from ingot casting to building giant integrated equipment for continuous casting. This involves pouring molten steel through a bottomless mold that is cooled by water to partially solidify it. The steel is then pulled down through a series of rolls to form steel plates or other shapes required by the factory and construction companies. Actually the new technology for twin-roll and single-belt casting is “moving the mold” – the rollers and belts move with the steel as it cools and solidifies. This allows direct casting to a thickness of only a few millimeters, after which only minimal rolling is required.

As Bessemer, a prolific British inventor, envisioned, the twin-roll process has been adopted by Nucor, a large steel company in the United States. Known as Castrip, it produces steel in two factories. One of the advantages of twin rolls and belt casting is compactness. Nucor estimates that the Castrip plant requires only 20 hectares (50 acres) and produces only 500,000 tons of steel every year, providing a good return on investment.

Innovation is Alive and Well in the Steel Industry via Continuous Casting

Steelmakers are constantly working hard for technological improvement. When many US steel companies focused on cost reduction and rationalization at the turn of the century, Nucor Corp. A U.S. Steel giant, not only innovated and invested in replacing electric arc furnaces, but also innovated and invested in direct casting and other downstream technologies.

Belt-casting Process

About belt casting process, Factories in the UK, Europe and China are adopting the same technology and hope that achieving low-volume flexibility while maintaining economics will encourage steel producers to get closer to the market, and may even see a good return such as the integrated steel manufacturing and automotive assembly line pioneered by Henry Ford 10 decades ago.

The reduction in energy use and the possible reduction in transportation costs will greatly reduce the carbon footprint of steel. Although the carbon tax is now very heavy, it may be more serious in the future. Soon, some people will come up with the idea of ranking steel products through carbon impact, adding momentum to technologies that can significantly rolling, reduce heating and transportation during manufacturing.

New technologies are always facing new challenges in the development process, and liquid metal steel plates are no different. According to economists, since 2012, Germany’s Salzgitter has been producing a special steel for single belt casting. One of the biggest challenges they face is keeping the plates on the cast strip. Even small changes can affect the quality of the finished paper. Salzgitter achieved this by operating a vacuum under the board, but McGill University in Montreal, Quebec, Canada – one of the pioneers of new technology – achieved the same result with magnets.

Either way, it is hoped that the combination of belt casting or twin roll and belt casting will not only reduce costs. The University of Warwick Research Center managed to produce advanced low-density steel that is stronger, lighter, and more flexible than conventional steel. Although the belt casting process opens the door for larger sized sheets, a twin-roller method that is limited in size may allow.

Continuous Casting

In the economist, one article details is exactly for content as some steel producers around the world are looking for better alternatives to traditional blast furnaces. Slab continuous casting and re-rolling lines are the epitome of US steel companies and major Asian steel mills.

One of the main attractions of the EAF plant is that they produce the final product through a continuous casting route. The liquid metal is taken out of the refining vessel, and for a flat rolled product, it is continuously cast into a slab of 80-120 mm thick, which can then be further rolled into a thinner slab. However, both steelmakers and university research centers are committed to developing technologies that can directly and continuously cast sheets while maintaining adequate quality standards, even for automotive applications. One such project at Warwick University in the United Kingdom is the

development of new high-tech steels that are specifically designed for casting onto belts and then require relatively limited rolling to final specifications.

It seems that innovation and technological development still exist and are good in the steel-making industry, and may not only maintain cost competitiveness, but also provide industry choices to deal with the threat of aluminum and other products in automobile manufacturing.
