Corundum refractory clay is a refractory clay with corundum as the main raw material, which has high refractoriness, high strength and good corrosion resistance. It is widely used in furnace joints in steel, glass, ceramics, cement and other industries. · High refractoriness: good refractoriness, suitable for high temperature environment. · High strength: has high mechanical strength and can withstand large loads. · Good corrosion resistance: can effectively resist chemical corrosion and is suitable for harsh environments.
Steel Industry: used in the joints of blast furnaces and hot blast furnaces.
Glass Industry:used in the joints of glass melting furnaces.
Ceramics Industry: used in the joints of ceramic kilns.
Cement Industry: used in the joints of cement rotary kilns.
