Silicon carbide includes black silicon carbide and green silicon carbide, among which: black silicon carbide is made of quartz sand, petroleum coke and high-quality silica as the main raw materials, which are smelted at high temperature in a resistance furnace. Its hardness is between corundum and diamond, its mechanical strength is higher than corundum, and it is brittle and sharp. Green silicon carbide is made from petroleum coke and high-quality silica as the main raw material, adding salt as an additive, and smelted at high temperature in a resistance furnace. Its hardness is between corundum and diamond, and its mechanical strength is higher than that of corundum.

1. Silicon carbon can be used as metallurgical deoxidizer and high temperature resistant materials in smelting.
2. Silicon carboncan also be used as abrasive materials,which can be used to make abrasive tools,such as grinding wheels, oilstones, grinding head and so on.
3.Silicon carbon is a new kind of reinforced steelmaking deoxidizing agent and ideal thermal insulating agent.it is used for deoxidizing. The usage dose is 14kg/t can make electricity consumption to reduce 15-20kw/h and time to reduce 15-20min per furnace to raise productivity rate to 8-10%.
