REACTION BONDED SILICON CARBIDE (RB SIC)


RB SiC is of excellent wear-resistance, impact-resistance, easy operation are ideal surface wear-resisting material for material transfer equipment in mining, iron & steel works, thermal & power plants, mine, etc, and can extend operating life of equipment effectively. Theoretically the life time of the alumina ceramic is about 260 times longer than that of manganese steel and 170 times longer than that of chrome steel. Thanks to the excellent hardness and abrasive resistance, it can effectively protect the part where need wear protection, so as to prolong the service life of the equipment.

Available Shape and sizes:


1) Thickness: from 6mm up to 25mm 

2) Regular Shape: SISIC plate, SISIC Pipe, SiSiC Three Links, SISIC Elbow, SISIC Cone Cyclone. 

3) Remark: Other sizes and shape are available upon requests. 


Application:


Plate, beam, roller etc. kiln furniture and radiation tube, burner, nozzle, thermalcouple tube etc.. structural parts and functional parts. It is an ideal wear resistant material, which is especially suitable for the strong abrasive, coarse particles, classification, concentration, dehydration and the other operations. It is widely used in mining industry, steel industry, coral processing industry, chemical industry, raw material-making industry, mechanical sealing, surface sandblasted treatment and reflector etc. 

Key benefits:


1) Low porosity, good wear-resisting 
2) High strength, good thermal shock resistance. 
3) High thermal conductivity, good heat transfer property 
4) Good coefficient of heat radiation 
5) Max working temperature 1380℃
