Dynamic FEM simulation of temperature distribution for rollers hardfacing process

DU Han-ting,CHEN Bing-quan,MU Jun-wei,HAN Fang,ZHANG Zheng-hua (School of Material Science and Engineering WHUT,Wuhan 430070,China)  
Using ANSYS finite element software, the build-up welding temperature field of roller was numerically simulated. In the process of simulation,the application of moving welding heat source was realized;moving and heating process of welding arc and the instantaneous variation of the temperature field were properly simulated;the nonlinear relationship between thermo-physical property parameters and temperature was taken into consideration.Finally the build-up welding temperature field for 70Cr3Mo was analyzed as an example.The results were in agreement with reality.
