Abstract The steadystate heat transfer model was established by finite element software ANSYS, and based on the element birth and death technology, the melting of slag skull on the surface of stave was simulated. The temperature distribution and heat load of iron cast stave were analyzed in the different conditions of stave, including with fixed and removed slag skull, destroyed and disappeared stave. The results showed that heat load of stave was increased with increasing gas temperature. Increasing cooling water rate and decreasing stave wall thickness had small effect. The heat load was dramatically increased when the slag skull was removed and the stave was disappeared.
