摘要
利用有限元软件ANSYS对使用复合铸造方法生产球墨铸铁-硬质合金复合辊环的残余应力进行数值模拟.根据数值模拟结果,采用球墨铸铁/硬质合金包覆面积比为0.344∶1、截面积比为0.4∶1,球墨铸铁浇注温度为1 320℃、硬质合金预热温度为800℃,成功制得扩散区宽达6 mm且无缺陷的复合辊环.
Abstract
The residual stress of ductile iron-cemented carbide compound roller ring produced by compound casting was simulated by ANSYS.According to the numerical simulation results,the process parameters were determined as follows:the coating area ratio of ductile iron to hard alloy of 0.344∶1,the cross-sectional area ratio is 0.4∶1,the cast-ing temperature of ductile iron of 1 320℃,and the hard alloy preheating temperature of 800℃.The compound roller with diffusion zone width of 6 mm without macro and micro defects was successfully prepared.
