Product Description

Product Description

Black silicon carbide (SIC) is made from quartz sand and carbon( anthracite coal tar or petroleum coke) in electric esistance furnace at high temperature. It has the characteristic of high hardness, excellent electrical and heat conductivity, low thermal expansion, and high abrasion resistance. Thus, SIC is the most suitable material of abrasives, refractories, deoxidizer of metallurgical, special ceramics, electric heating elements and so on.

Silicon Carbide Applications

Silicon Carbide added to the furnace turn into the Si and C for casting iron, One is to improve the carbon content, and the second is to strengthen the reducibility of iron liquid. Greatly reduce the adverse effect of corrosion the furnace. Prevent carbide separate out, Increasing the amount ferrite, The cast iron compact structure, Significantly improve the processing performance and cutting face is bright and clean. Increase the nodular case iron graphite ball number per unit area. Improve spheroidizing rate. For reducing nonmetallic inclusion and slag, eliminate shrinkage, eliminate subcutaneous blowhole also has a good effcet.
