Metallurgical Silicon Carbide High Silicon Carbide Hardness Speed Up Reaction 1mm 10mm
Emery, also known as silicon carbide (SiC), is produced by high-temperature smelting of electric furnaces such as quartz sand, petroleum coke (or coal char), and wood chips (which require the addition of salt when producing green silicon carbide). Silicon carbide is also a rare mineral in nature, Moissanite. Silicon carbide is also known as carbon silica. Among the non-oxide high-tech refractory raw materials such as C, N and B, silicon carbide is the most widely used and economical one, and it can be called gold steel sand or refractory sand.

Due to its stable chemical properties, high thermal conductivity, low thermal expansion coefficient and good wear resistance, silicon carbide has many other uses besides abrasives, such as coating silicon carbide powder on turbine impeller or cylinder block by special process. The inner wall can improve the wear resistance and prolong the service life by 1 to 2 times; the advanced refractory material used for the manufacture is heat-resistant, small in volume, light in weight and high in strength, and has good energy-saving effect. Low grade silicon carbide (about 85% SiC) is an excellent deoxidizer, which speeds up steelmaking and facilitates control of chemical composition and quality of steel. In addition, silicon carbide is also widely used to make silicon carbide rods for electric heating elements.
Silicon carbide has a high hardness and a Mohs hardness of 9.5, which is second only to the world's hardest diamond (10 grade). It has excellent thermal conductivity and is a kind of semiconductor. It can resist oxidation at high temperature.
Type and use:
1. Non-ferrous metal smelting industry application
The use of silicon carbide has high temperature resistance, high strength, good thermal conductivity, impact resistance, and high temperature indirect heating materials, such as a potting distillation furnace. Rectification furnace tray, aluminum electrolysis tank, copper melting furnace lining, zinc powder furnace arc plate, thermocouple protection tube and so on.
2. Application in the steel industry
Use silicon carbide for corrosion resistance, thermal shock resistance and wear resistance. Good thermal conductivity for large blast furnace linings to increase service life. The use of its thermal conductivity, thermal radiation, high thermal strength, the manufacture of thin plate kiln furniture, not only can reduce the capacity of the kiln furniture, but also improve the capacity and product quality of the kiln, shorten the production cycle, is the ceramic glaze baking sintering The ideal indirect material.
3. Application of metallurgical beneficiation industry
Silicon carbide hardness is second only to diamond, it has strong wear resistance. It is an ideal material for wear-resistant pipes, impellers, pump chambers, cyclones and mine linings. Its wear resistance is cast iron and rubber service life is 5 -20 times, it is also one of the ideal materials for aviation flight tracks.
Building ceramics, the application of the grinding wheel industry uses its thermal conductivity. The characteristics of heat radiation and high heat intensity make thin plate kiln furniture, which not only can reduce the capacity of kiln furniture, but also improve the capacity and product quality of the kiln, shorten the production cycle, and is an ideal indirect material for ceramic glaze baking and sintering.
In year of 2012, our company won ferroalloy export license which is approved by the Ministry of Commerce. At present there are 10 sets of intermediate frequency electric furnaces and 4 cored wire production lines. Annually produce more than 20,000 tons of steel-making and casting used subsidiary material, including Nodulizer (FeSiMg), Inoculant (Silicon series, Barium series, Calcium series and Zirconium series, etc), Ferro Alloys ( Ferro Silicon, Calcium Silicon, Barium Silicon, Silicon Aluminum, Calcium Silicon Barium, Calcium Silicon Barium Aluminum, Calcium Silicon Manganese, High Carbon Silicon, Silicon Carbide, and Carbon Additive), Deoxidizer ( Aluminum series and Calcium series ), Alloy Briquettes ( FeSi Briquette, Silicon Ball, SiC Ball, ect ), Alloy Slags (FeSi Slag, Silicon Slag, Manganese-rich Slag ) and Cored Wires ( FeSiMg, CaSi, CaFe, Pure Calcium etc).
Henan Guorui Metallurgical Refractories Co., Ltd was founded in 2006, which was specialized in manufacturing Iron- & steel-making and casting used subsidiary products. After 10 years of efforts and development, with the character of rapid development, larger scale, stable quality and trusted by customers, it has become a benchmarking enterprise in ferroalloy industry of China.
