Silicon Carbide for Steelmaking Deoxidation and Casting
There are many advantages of melting molten iron in cupola furnaces or electric furnaces, and adding the pretreatment agent SiC. Silicon carbide is divided into abrasive grade and metallurgical grade, the former is high purity and expensive, and the latter is inexpensive. The silicon carbide added to the furnace is converted into carbon and silicon of cast iron, one is to increase the carbon equivalent; Second, it strengthens the reducibility of molten iron and greatly reduces the adverse effect of corroded charge. The addition of silicon carbide can prevent carbide precipitation, increase the amount of ferrite, make the cast iron structure dense, significantly improve the processing performance and make the cutting surface smooth. Increase the number of graphite balls per unit area of ductile iron to improve the nodularization rate. It also has a good effect on reducing non-metallic inclusions and slag, eliminating shrinkage porosity, and eliminating subcutaneous porosity.
Silicon carbide is a compound composed of carbon and silicon mainly combined by covalent bonds. It is a non-oxidizing material. Because it exhibits significant instability in high-temperature oxidizing atmospheres, the oxidation reaction proceeds rapidly especially when the temperature exceeds 1627°C. Its characteristics can be used to replace ferrosilicon and carburizing agents in the process of smelting ordinary carbon steel and some low alloy steels in converters and electric furnaces to deoxidize, heat and increase silicon and carbon in molten steel to achieve the purpose of reducing steelmaking costs. , achieved better results. Among them, the most commonly used quality is concentrated at 80%-95%, and the particle sizes are mainly 0-10mm, 0-5mm, 1-3mm, and 1-5mm (mostly used in casting).

Description |
| Sandblasting and engraving |
black |
generally purchase F36, F46, and the content requirement is about 97.5-98%; for export orders, the content requirement is between 98-98.5%. Such materials have hardness and cleanliness requirements. |
| Grinding wheel and sandpaper |
black |
generally 46#-90#, the grinding wheel uses F standard; the sandpaper uses P standard. |
| Brake pads |
black |
generally use CF500# and CF600# materials. |
| Furnace wall coating |
black |
generally uses 97% 325mesh. |
| Abrasives |
Black |
Customers purchase products concentrated in coarser grades than F220, with F46, F60, and F80 performing better. |
