Stave design performance is affecting the life of blast furnace is one of the most important factors . The newly developed copper- clad steel copper cooling stave able to overcome insufficient wall strength , steel stave poor heat transfer capability shortcomings , and has broad application prospects , but it can work , the feasibility of the production to be verified . This cooling wall heat transfer model was established by using ANSYS software, its temperature and stress field numerical simulation to analyze the situation in different conditions of service , the effects of different factors on the thermal stress field distribution . The most difficult conditions simulated maximum temperature cooling wall , the wall material is less than the maximum operating temperature , that it can meet the requirements ; resulting copper-steel interface, the maximum tensile stress is less than the actual production of the tensile strength measured , verify the feasibility of its production . Based on a simulation test and blast furnace site measured data obtained by comparison with the simulation results and found that the error in the acceptable range , verify the rationality of the model . Also the simulation process parameterization, comparing different cooling wall structure brings different effects , which made ​​structural optimization opinions. These results for the longevity of the cooling wall has some theoretical significance and practical value, can stave design and production to provide guidance and basis .
