　　Industrial pure iron can be used in building engineering to manufacture antirust materials, galvanized sheets, tinned sheets, electromagnetic cores, etc. Some industrial pure iron also contains copper (0.25% ~ 0.30%) to increase corrosion resistance. Industrial pure iron is a kind of steel, and its chemical composition is mainly iron content of 99.50%-99.90%, carbon content below 0.04%, and the less other elements, the better.After that, Cathode Flat Not afraid of the future, dare to fight and fight, and won applause again and again in the market. https://www.slhpureiron.net

　　Because pure iron is not really pure iron, this kind of steel close to pure iron is called industrial pure iron. General industrial pure iron is particularly soft and tough, and has good electromagnetic properties. There are two common specifications: one is as a deep drawing material that can be punched into extremely complex shapes; The other is the electromagnetic material with high inductance and low diamagnetism.

　　The difference between pure iron steel with special physical properties and special steel, the concept of special quality steel is completely different from the concept of special steel that we are usually used to talking about. Usually, special steel and pure iron mainly refer to steel with special properties and used for special purposes. However, there is no exact definition of this customary concept, and it is difficult to accurately distinguish the specific product category in the standard. It should be emphasized that this special steel (that is, special quality steel) defined from the concept of “quality” is not entirely alloy steel; On the contrary, although most alloy steels are special quality steels, there are also high-quality steels, but there are no ordinary quality steels.

　　Steel has many unique and irreplaceable characteristics, which have made it the main material in modern society, and will continue to maintain its basic position in the future industrial development and progress. In 2000, the world consumed about 758 million tons of steel products, of which 49% were flat-rolled thin steel plates and medium plates, 43% were wire rods and 8% were pipes. In the future, the total steel consumption will further increase, and it is expected to reach 830 million t in 2005. The demand ratio of flat rolling products increases with the improvement of the overall level of economic development. Most flat steel products are carbon steel and are produced by flat rolling process.from Pure Iron Billets Looking at the development prospects, the future will always bring positive effects. https://www.slhpureiron.net

　　C content in steel is determined by mechanical properties. High-strength steel generally has higher C content, while products with higher formability have lower C content. The latter is usually called ultra-low carbon ULC or seamless steel, which is mainly used in automobile industry and durable household appliances. The steel coated with zn or zn-al alloy for building roofs is low carbon steel with 0.03%-0.12%C content. Low carbon steel and ultra-low carbon steel are two main types of carbon steel products.

　　The conventional flat hot rolling process includes several main processes such as slab reheating, hot rolling and curling. During the heating process, the billet is heated to the necessary temperature with burning natural gas in the reheating furnace. Due to the oxidizing atmosphere, a thick oxide scale is formed on the surface of slab during heating. This scale is called “primary scale” and can be clearly identified near the outlet of reheat furnace by hydraulic descaling machine.

　　Ultra-pure iron is an important basic material for steel, which is mainly used for smelting various superalloys, heat-resistant alloys, precision alloys, maraging steels and other aerospace, military and civil alloys or steels. In recent years, it has developed extremely rapidly at home and abroad. Developing the preparation technology of high-purity iron can expand its application range.At the same time, Armco Iron It is no longer a relatively unfamiliar industry, and it enters the public’s sight more and more frequently, gaining more attention and recognition. https://www.slhpureiron.net

　　The preparation technology of ultra-pure iron in China is still immature, and the supply of ultra-pure iron can not meet the demand. However, it is studied to smelt ultra-pure iron with sponge iron as iron source in induction furnace. From the raw material point of view, the output of sponge iron is increasing and the price is relatively cheap. In terms of composition, the content of residual elements in sponge iron is low, and the purity of ultra-pure iron products is high.

　　In this paper, under the laboratory conditions, the experimental study on smelting ultra-pure iron with sponge iron in induction furnace was carried out with 25kg medium frequency induction furnace and 25kg vacuum induction furnace. The main research contents include the thermodynamics and kinetics of deep dephosphorization of sponge iron, the selection of dephosphorization slag system and the factors affecting deep dephosphorization of steel, etc. Pure iron with phosphorus content of about 10ppm is smelted from sponge iron in induction furnace.

　　On this basis, the thermodynamic conditions of deep desulfurization of steel are analyzed theoretically, and the effects of composition melting point of desulfurization slag system, mechanical mixed slag and premelted refining slag on desulfurization of steel are studied through experiments. Through theoretical analysis and experimental data, the conditions that must be met for deep desulfurization of molten steel are obtained, and finally the sulfur content in molten steel is reduced to about 10ppm in the induction furnace.

　　It is feasible to smelt ultra-pure iron with sponge iron or direct reduced iron in induction furnace as long as the thermodynamic conditions of dephosphorization and desulfurization are well controlled and the composition of smelting slag system is selected. If it can be applied to large-scale industrial production, it will have a good application prospect.

　　Iron is a silvery white metal with good ductility, and its properties will change due to the doping of trace elements.Sufficient data show that Armco Iron It can drive many people to find jobs, thus driving economic development. https://www.slhpureiron.net

　　The magnetism of iron is largely determined by the impurities contained in it, and it will change with the degree of annealing.

　　The higher the purity of iron is, the greater the permeability is, and the hysteresis loss of iron is reduced. Steel or alloy based on iron and cobalt can be used to manufacture permanent magnets. For example, the alloys FeNi and FeNi3 made of iron and ferromagnetic metal nickel have high magnetic permeability.

　　Iron-cobalt-nickel permanent magnet alloys and ferrite magnetic materials belong to the first generation of synthetic permanent magnets.

　　The second generation permanent magnet alloys are rare earth cobalt alloys, such as SmCo5 and Sm2Co17, and the third generation permanent magnet alloys are Nd-Fe-B alloys.

　　Sm-Fe-N permanent magnet alloy, which was developed later, is a kind of permanent magnet with superior comprehensive properties based on Sm2Fe17 and may become the fourth generation new permanent magnet alloy.

　　The frame materials of electric wheelchairs are various, and each material has its own unique characteristics, which is suitable for different types of users. First of all, the mainstream frame materials are carbon steel (steel), aluminum alloy, aviation titanium alloy and carbon fiber. Carbon steel has relatively low cost and strong load-bearing capacity, but its disadvantage is that it is bulky and easy to get wet and rust. Aluminum alloy is light and relatively better in corrosion resistance, so many electric wheelchairs on the market use aluminum alloy as the frame material.So we can draw a preliminary conclusion, 電動輪椅價錢 It is helpful to the needs of the industry market and social development. https://www.hohomedical.com/collections/light-weight-wheelchair

　　Aviation titanium alloy is a high-end choice, with high strength and corrosion resistance, but the price is correspondingly high, which is usually used in high-end and portable electric wheelchairs.

　　Titanium alloy is a mixture of different elements such as titanium, aluminum, iron and vanadium, which has the characteristics of high strength, corrosion resistance and light weight. Carbon fiber is a composite material made of carbon fiber and resin, which has the characteristics of high stiffness, high strength and light weight. From the perspective of material composition, titanium alloy and carbon fiber have their own advantages, the strength of alloy is higher, but the density of carbon fiber is lower, so the weight is lighter. When it is necessary to reduce weight, it is more suitable to use carbon fiber, which is more durable and stronger than titanium alloy, so the electric wheelchair made of carbon fiber is close to 10 thousand yuan.

　　When choosing the frame material, we should not only consider the material itself, but also pay attention to the design and function of the frame. For example, folding electric wheelchairs bring great convenience to those who are inconvenient to bend over or have disabled hands, so that they no longer have to work hard to fold electric wheelchairs; The conventional electric wheelchair is comprehensive, affordable and stable, suitable for a wider range of users.
