①Black silicon carbide contains about 95% SiC, its toughness is higher than green silicon carbide, mostly used for processing materials with low tensile strength, such as glass, ceramics, stone, refractory materials, cast iron and non-ferrous metals.
② green silicon carbide contains about 97% SiC, good self-sharpening, mostly used for processing cemented carbide, titanium alloy and optical glass, also used for honing cylinder liner and precision grinding of high-speed steel cutting tools.
Silicon carbide has four main application areas, namely: functional ceramics, advanced refractories, abrasives and metallurgical raw materials. Crude silicon carbide can be supplied in large quantities and cannot be regarded as a high-tech product.
High-carbon silicon carbide has stable physical and chemical properties, good deoxidizing effect, and can be added into the steel water to quickly react with the oxygen in the steel water to form a steel slag floating to the surface of the steel water to achieve the purpose of deoxidizing.
High-carbon silicon has the following characteristics:
1. high carbon alloy is a good product of ferrosilicon in steel production, which has the advantages of reducing production cost and resource reuse.
2. High-carbon silicon is a kind of silicon type coal with broad market prospect.
3. High carbon silicon is used in steel making as a deoxidizer to reduce the oxygen content in the melt by reaction.
4. High carbon silicon can be processed into ball, powder or granule according to customers' requirements.
5. High-carbon silicon has high density and purity, and has little contamination to the steel.
6. High-carbon alloys can maintain a high and stable recovery rate and stable performance.
7. High-carbon silicon can reduce the use of alloys, thus reducing the cost of steelmaking and improving economic efficiency.
8. High carbon SiS can improve the quality of molten steel and improve the quality and performance of steel.
