The graphite and boron nitride in the dope are of lubricating and anti-bonding functions, the carborundum is of wear resistance function, the manganic oxide, titanium dioxide and alumina are of strong infrared ray emission and the dope mad of zirconium dioxide, zircon quartz, feldspar and cerium oxide has good compact structure and strong fire-proof and the manganese sesquioxide can catalyze C, S and N for conversion. Therefore, the invention is applicable for use in dynamic furnaces such as coal dust furnace, boiling furnace and fluidized bed furnace.
