company news about What is the difference between silicon carbide and high carbon silicon?

Silicon carbide is an inorganic substance with the chemical formula SiC. Since the natural content is very small, silicon carbide is mainly artificial. It is made of quartz sand, petroleum coke (or coal coke), and wood chips (salt needs to be added when producing green silicon carbide). And other raw materials are smelted at high temperature in a resistance furnace.

① Black silicon carbide contains about 95% SiC, and its toughness is higher than green silicon carbide. It is mostly used to process materials with low tensile strength, such as glass, ceramics, stone, refractory materials, cast iron and non-ferrous metals.

② Green silicon carbide contains more than 97% SiC and has good self-sharpening properties. It is mostly used for processing cemented carbide, titanium alloy and optical glass. It is also used for honing cylinder liners and precision grinding of high-speed steel cutting tools.

Silicon carbide has four main application areas, namely: functional ceramics, advanced refractory materials, abrasives and metallurgical raw materials.

High carbon silicon is a novel composite alloy deoxidizer that can replace the more expensive traditional deoxidizers - ferrosilicon powder, calcium carbide, carbon powder and alloy powder. High-carbon silicon has stable physical and chemical properties and good deoxidation effect. When added to molten steel, it can quickly react with the oxygen in the molten steel to form steel slag that floats to the surface of the molten steel to achieve the purpose of deoxidation.

High carbon silicon has the following characteristics:

1. High carbon alloy is an excellent product of ferrosilicon in steel production and has the advantages of reducing production costs and reusing resources.

2. High carbon silicon is a silicon briquette with broad market prospects.

3. High carbon silicon is used as a deoxidizer in steelmaking to reduce the oxygen content in the melt through reaction.

4. High carbon silicon can be processed into balls, powder or granules according to customer requirements.

5. High-carbon silicon has high density and purity, and has no pollution to molten steel.

6. High carbon alloy can maintain a high and stable recovery rate and stable performance.

7. High-carbon silicon can reduce the use of alloys, thereby reducing steelmaking costs and improving economic benefits.

8. High carbon silicon silicon can improve the quality of molten steel and improve the quality and performance of steel.
