corundum mullite furnaces accessories push plate size can be customized high temperature resistance
Product Name :Corundum mullite push plate
Product introduction :
Corundum mullite product : It is made of fused white corundum and fused mullite as the main raw materials, introducing alumina and Suzhou soil, stirring granulation, pressing molding, drying and dehydration, and high temperature sintering. It has the characteristics of fire resistance temperature ( 1500 °C ~ 1830 °C ), good thermal shock stability ( acute denaturation resistance ), high load softening temperature, good slag resistance and permeability resistance, low creep resistance and strong product stability. It is widely used in the high temperature parts of tunnel pusher kiln, shuttle kiln and electric furnace in ceramics, electronics, magnetic materials, rare earth, fluorescent materials, glass, metallurgy and other industries.
