Low Creep Fire Clay Brick 36-45% Al2o3 Fireclay Refractory Brick
Low Creep Clay Brick
Silicon Mullite Wear-Resistant brick is made from super high bauxite clinker and silicon carbide as main raw materials by high pressure forming and high temperature firing. The product has high compressive strength at room temperature and high temperature structural strength, good thermal shock stability, continuous formation of protective layer during use, good wear resistance, strong resistance to spalling, suitable for cement kiln transition belt, cooling belt, kiln mouth and other parts.
▌FEATURES
1. Low creep rate；
2. High mechanical strength；
3. Good abrasive resistance；
