Abstract: Through calculation,it is the appropriate that choices a chromium aluminum brick used as liner.The damage mechanism of refractory material is analyzed. Two main types of damage of refractory materials are put forwarded: thermal spalling and structure spalling. The technological transformation is introduced in a copper water jacket furnace liner instead of refractory liner. Combin ing with the melting process in the furnace, the mechanism of liner hanging slag is analysed, three conditions to form hanging slag are put forward : ⑴thermodynamic conditions; ⑵partial pressure conditions of the free oxygen in the furnace;⑶ the temperature conditions.
