Silicon carbide for steelmaking deoxidation and casting
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).

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 |

Customers purchase products concentrated in coarser grades than F220, with F46, F60, and F80 performing better. |
The use cost of silicon carbide is low, and the addition of silicon carbide particles can prevent the precipitation of carbide, increase the amount of ferrite, reduce the white mouth, make the cast iron structure dense, significantly improve the processing performance and make the cutting surface smooth; Especially in smelting, it is very beneficial to increase the graphite core, increase the number of graphite balls of ductile iron, improve the graphite morphology of gray iron, etc.; After a large number of experiments, it is concluded that silicon carbide has become an important material in the production of gray cast iron. Generally, when silicon carbide is used as an inoculant, silicon carbide is added to the firing ladle with molten iron in the form of broken granules, which can effectively play the role of inoculation treatment of thin-walled iron castings.
The amount of silicon carbide used in cast iron is very small, which has little effect on the chemical composition of cast iron, but has a great impact on its microstructure, so it can improve the mechanical properties of gray cast iron, and also has a significant impact on its physical properties.
