black silicon carbide supplier
Black silicon carbide supplier always supply the silicon carbide which is made of quartz sand, petroleum coke or coal coke, sawdust and other raw materials through high temperature smelting in a resistance furnace. The smelted silicon carbide blocks through crushed, washed with acid and alkali, magnetic separation and sieving or water separation to produce it of various particle sizes.
Silicon carbide can be divided into black silicon carbide and green silicon carbide. The black silicon carbide is with metallic luster, container SiC more than 95%, and has greater strength than green silicon carbide, but lower hardness, it is mainly used for grinding cast iron and non-metallic materials.
Due to stable chemical properties, high thermal conductivity, small thermal expansion coefficient and good wear resistance, black silicon carbide supplier always sell the black silicon carbide to used as abrasives and refractory, etc. Following more details describe for the appliance of black silicon carbide:
1.Abrasive: Black silicon carbide is mostly used for grinding optical glass, hard alloy, titanium alloy and bearing alloy and bearing steel as well as sharpening of high-speed steel tools because of its certain toughness.
2.Refractory material: Black silicon carbide has good thermal shock resistance, so it is a high-quality refractory material. According to the production process of the product, it can be divided into recrystallized black silicon carbide, products, high-temperature hot-pressed products, products with silicon nitride or clay as a coupling agent, etc. The main products and uses are: high temperature furnace components, supports.
3.Metallurgy industry: a new type of strong composite deoxidizer, which replaces the traditional silicon powder and carbon powder deoxidation. In comparison, the physical and chemical properties are more stable, the deoxidation effect is better, the deoxidation time is shortened, the slag is formed earlier, and the reducing atmosphere is strong , Save energy, improve steelmaking efficiency, improve quality, reduce consumption of raw and auxiliary materials, reduce environmental pollution, improve working conditions, and improve the comprehensive benefits of electric furnaces.
4.Other fields: electrical industry, black silicon carbide material is also widely used as electric heating element, high temperature semi-superconductor material, far infrared plate, arrester valve material, etc.
As one professional black silicon carbide supplier, Anyang Huatuo Metallurgy Co., Ltd always supply the silicon carbide in the size 0-10mm/1-10mm which always used for the metallurgy industry as deoxidizer, we always supply the qualified black silicon carbide, if any interest welcome for consult.
