Refractory Corundum mullite/mullite-Ceramic Pusher Plate/ Sagger has a high content of Al2O3. Corundum and mullite with low impurity content are the main materials. Operating temperature is 1800℃.We developed it into the advantages of excellent thermal shock resistance and deformation resistance at high temperature, long life, meticulous on surface, good bonding strength, not easy to fall off, good strength in high temperature, not easy to deform, etc. It has been widely used in a variety of electric furnace firing products bearing board in high temperature.
Widely used in ceramics, electronics, magnetic materials, rare earth, fluorescent materials, glass, metallurgy and other industries in the tunnel push plate kiln, shuttle kiln, electric furnace, and other high temperature parts.
