Abstract：The thermal properties and deformation of new type cast copper stave with buried copper pipe were studied. The result shows that there is no difference in thermal properties between cast copper stave and rolled copper stave. The cooling capacity of cast one is very good. There is no air gap between wall and buried copper pipe. Based on the finite element analysis, the temperature distribution, stress and strain of cast copper stave at high temperature were calculated with the method of thermostructure coupling and calculated data were almost identical with measured. The result indicates that both the temperature and the stress of copper stave under BF operating condition are insufficient to cause cracking. The cast copper stave can satisfy the requirements of long campaign.
