RBSIC / SiSiC Silicon carbide beam is applicable to the load-bearing structural frame in tunnel kiln, shuttle kiln and other industrial kilns.
The reaction bongded silicon carbide beam has high temperature bearing capacity, long service life and no bending deformation after long-term use. It is an ideal kiln furniture for sanitary porcelain and electric porcelain kilns and other industries.
RBSIC / SiSiC Silicon carbide has good thermal conductivity, which can significantly save energy consumption without increasing the weight of kiln car.
Product features:
- Good thermal shock resistance;
- Excellent oxidation resistance;
- Good thermal conductivity;
- Long service life;
- Excellent high-temperature strength and good comprehensive mechanical properties.
