Technical Parameters

Product description

Corundum mullite brick are refractory materials made of high-quality fused mullite or sintered mullite as the main raw material, formed by high pressure and fired at high temperature in a liquefied gas shuttle kiln. This type of products has the characteristics of high density, high load and softness, low creep, high mechanical strength, good chemical stability, strong electrical insulation ability, and strong resistance to acid, alkali, slag and corrosion in oxidizing or reducing atmospheres.

Application:

Corundum mullite brick are usually use in large blast furnaces, steel rolling furnaces, refractory materials, glass, chemicals, fertilizers, ceramics, special ceramics, electric porcelain, enamel, non-ferrous metallurgy and other high-temperature kilns.
