【Abstract】 The numerical simulation technology is applied on the development of double metal composite bend pipes. So that the defects of original design are found in time by simulation of the cast process of double metal composite bend pipes, and the theory basis is presented for updating design. The double metal composite bend pipe of high Cr iron/16 Mn steel is produced, so the confliction problems between wear resistance and jointing of bend pipe is solved.更多还原
