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).

Application Direction	Silicon Carbide	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.

In the process of smelting cast iron with intermediate frequency furnace, the accompanying problems such as poor nodularization, less graphite balls, large use of nodularizing agent, more supercooled graphite in gray iron castings, A-type graphite can not meet customer requirements, and processing difficulties follow. This product can effectively improve the metallurgical quality of molten iron, thereby reducing the above problems.
Features:
1. Increase the graphite nucleation core and enhance the graphite nucleation ability. Reduce the subcooling degree of molten iron and reduce the tendency of castings to white.
2. Good deoxidation effect, purify molten iron.
3. Extend the service life of the furnace lining.
4. Reduce the supercooled graphite in gray cast iron and promote the generation of A-type graphite.
5. Adding to ductile iron production can increase the number of graphite balls, improve the nodularization rate, make the graphite balls more round and small, and reduce the amount of nodularizing agent.
