Kilneye огнеупорный castalbe для цементной печи

Besides bearing more than 1400°C high temperature, the kilneye pouring material for cement kiln needs to bear the damage caused by mechanical stress, heat stress and chemical corrosion during the use. According to its actual working condition, our company has developed the special kilneye pouring material of corundum-silicon carbide. It is of behaviors of high mechanical strength, high refractoriness, good thermal shock resistance and alkali resistance, and of 10 to 12 months’ life cycle, gaining high praise of users.
