　　As a new kiln handling rubbish, the rubbish burning boiler lining will withstand rather severe conditions, such as high temperature, corrode and abrasion because of the complicated commposition consist of it. Therefore, the properties for the refractory used for it was required os very high, they include fire-resistant, conductivity, mechanical strength, anti-erosion. Aimed at above requirements, our factory have developed successfully a serial products consists of silicon carbide, silica, and high alumina, applied successfully at 35t/d, 100t/d,200t/d,310t/d and 1000t/d rubbish burning boiler. Several properties of lining materials even higher international standards.
