摘要
本文以18CrNiMo7-6齿轮钢连铸坯为研究对象,采用ProCAST大型铸造仿真软件对连铸坯的连铸过程进行了稳态模拟,建立了三维稳态模型。通过C语言外部程序控制连铸过程,模拟工艺参数的变化,模拟了连铸过程温度场分布情况,分析连铸坯产生铸造缺陷的原因。随后,以某工厂提供的18CrNiMo7-6齿轮钢的圆形连铸坯为材料,研究了其横截面显微组织、硬度梯度分布和残余应力分布的情况。最后,建立“冶炼工艺参数-显微组织-力学性能”之间的定量关系,总结并讨论了铸造工艺可能的优化途径。
In this paper,the steady-state simulation of the continuous casting process of the 18CrNiMo7-6 gear steel billet was carried out by using the ProCAST large-scale casting simulation software.The continuous casting process was controlled through an external program in C language,and the changes in process parameters were simulated.The distribution of temperature field during the continuous casting process was simulated,and the reasons for casting defects during the processes were analyzed.Subsequently,the circular continuous casting billet of 18CrNiMo7-6 gear steel provided by a certain factory was used as the raw material to study its cross-sectional microstructure,hardness gradient distribution,and residual stress distribution.Finally,a quantitative relationship between smelting process parameters,microstructure,and mechanical properties was established,and possible optimization approaches for the casting process were summarized and discussed.
