| Abstract: | The thermal boundary condition of the cast iron cooling stave with surface alloyed steel pipe was used for numerical simulation of temperature field and commercial software ANSYS and the method of coupling heat-structure were used to calculate thermal deformation of steel pipe at high temperature, and analyze the influence of air gap and thermal deformation on the life of cooling stave. The optimal size of air gap and hot load to guarantee long life of cast iron cooling stave were obtained. |
