Reaction Bonded Silicon Carbide High Strength High Straightness Sisic/ Rbsic Rollers and Beams Reaction sintering silicon carbide ceramics roller is mainly used for lithium battery industry, daily porcelain, sanitary porcelain, building ceramics and magnetic materials, such as roller kiln, high temperature burning with ideal kiln, with a long service life. It has high temperature strength, thermal shock resistance, high temperature creep resistance, strong resistance, good wear resistance.. Rollers with high - temperature bearing capacity of large, long-term use without bending deformation, especially suitable for tunnel kilns, shuttle kiln, in two - layer roller kiln and other industrial furnace load - bearing structure of frame. Clubs apply to daily - used ceramics, sanitary porcelain, Building Ceramic, Magnetic material and high temperature firing zone of roller kiln.
