Metallic silicon, also known as crystalline silicon or industrial silicon, is primarily used as an additive to non-ferrous alloys. Metallic silicon is the product that is smelted by quartz and coke in electric heating furnace, the content of element of main component silicon is in about 98% (contain Si content 99.99% also contain in metallic silicon), other impurity is iron, aluminium, calcium to wait..According to statistics, in 1985 the world consumed about 500,000 tons of silicon metal, of which about 60% was used for aluminum alloy, less than 30% for organic silicon, about 3% for semiconductor, and the rest for steel smelting and precision ceramics.
Use of the silicon matal
Silicon is widely used in smelting ferrosilicon alloy as alloying element in steel industry and as reducing agent in many kinds of metal smelting.Silicon is still a good component in aluminum alloys, most of which contain silicon.Silicon is the raw material of ultrapure silicon in electronic industry. The electronic devices made of ultrapure semiconductor monocrystalline silicon have the advantages of small size, light weight, good reliability and long life.Silicon carbide can be used as abrasive, quartz tube made of high purity silicon oxide is an important material for high purity metal smelting and lighting.It has the characteristics of small heat capacity, high mechanical strength, low thermal conductivity, non-combustion, non-toxic and tasteless, cutting, convenient transportation and so on. It can be widely used in metallurgy, electric power, chemical industry, ships and other thermal equipment and pipelines.
Belongs to energy-intensive manufacturing silicon metal smelting, silicon metal production in our country already has a long history, along with the national energy policy tightening and the development of energy conservation and emissions reduction, and to the promotion of the new energy, has become the primary silicon metal smelting products and processes, a lot of domestic new energy enterprises construction metal silicon, polycrystalline silicon, monocrystalline silicon, solar cells and so on a series of circulation industry chain, in the next few years is bound to affect the whole development of our energy and new energy should be.
From 2012 to 2017, China's exports of metallic silicon showed a fluctuating trend.Among them, the export volume of metal and silicon increased as a whole in 2017 compared with the previous year, reaching 83794.83 tons in 2017, up 17.24% compared with the previous year, with a larger increase.
Anyang daguan metal co., ltd. was established in 2006, specializing in the production of metallurgical accessories.After more than 10 years of efforts and development, has become a domestic rapid development, larger, stable quality, trusted by customers of the benchmark ferroalloy industry enterprises.
In 2012, our company obtained export license.The company has 10 sets of intermediate frequency furnace and 4 core wire production lines, with an annual output of more than 20,000 tons of auxiliary materials for steelmaking and casting.Mainly includes the ferroalloy (ferrosilicon, calcium silicon, silicon barium, calcium silicon, silicon barium aluminum, high silicon aluminum barium calcium, calcium silicon manganese, silicon, silicon carbide and carbon recarburizer), nodulizing agent (rare earth silicon magnesium alloy), nucleating agent (silicone, barium, calcium, zirconium, etc.), deoxidizer (aluminum and calcium), alloy ball (silicon, silicon, silicon carbide ball), alloy slag slag (ferrosilicon, silicon slag, rich manganese slag) and packet core.With excellent production equipment, strong technical force, advanced production technology and unique formula, the product ingredient content can be produced in strict accordance with customer requirements, in use with high efficiency, stable reaction, absorption and fusion of good characteristics.
At present, 40% of the products are used in large domestic steel mills and founders, including Shagang group, Rizhao iron and steel group, Shougang group, Wuhan iron and steel group, etc.60% of the products are exported to more than 30 countries and regions such as South Korea, Japan, Russia, Ukraine, Turkey, Germany, India, Australia and Iran, including posco iron & steel group, Hyundai iron & steel group and JFE iron & steel group.With stable quality and high quality technical services, our products have won the praise and trust of customers at home and abroad.
In the future, the competition will be more intense, Henan guorui will continue to strictly comply with the requirements of iso9001:2008 quality management system, continue to focus on customer needs, committed to providing newer, better quality products and more satisfactory services for steelmaking and casting industry. Henan guorui sincerely hope to join hands with more enterprises to advance together and create brilliant.
