Refractory Alumina Ceramic Roller is a kind of refractory material in roller kiln, as a role of bearing and transmission in the high temperature furnace. It is a key component of modern industrial track kilns and can transmit and bear ceramic products at a temperature of up to 1400 °C.
Alumina ceramic roller is kind of structural ceramic. The quartz ceramic roller is a key component in the glass horizontal tempering furnace, and is mainly used for carrying and transporting glass in the glass horizontal tempering furnace. The ceramic roller uses high-purity fused alumina as raw material, with high bulk density, high strength, low thermal expansion, good thermal shock stability, high dimensional accuracy, no deformation at high temperature, long service life, and no pollution to glass.
Alumina Ceramic Rollers for kilns used for firing wall tiles and wear-resistant bricks.
Alumina Ceramic Rollers for firing floor tiles, porcelain tiles.
Alumina Ceramic Ceramic Kilns Rollers for large and thick tiles, roof tiles, sanitary ware, and Magnetic Ceramics.
