Fired alumina-zirconia-C sliding plates: Taking plate corundum, fused corundum, zirconium corundum, zirconium mullite, etc. as the main raw materials, the high temperature performance of the skateboard is improved by adding an appropriate amount of metal fines and fine powders through high temperature reaction, and adding appropriate amounts of fine powders such as boron carbide to improve the oxidation resistance , With phenolic resin with high solid content and high residual carbon as binder. After forming, it adopts advanced heat treatment process, and after dipping and baking, it is made into high-performance skateboard.

has the advantages of stable volume, corrosion resistance and strong thermal shock resistance. It is generally used on ladle slides and converter slag block slides with a tonnage of more than 180 tons.
