【摘要】 应用CAFE法模拟了高氮钢的微观组织的凝固过程,模拟结果与实验比较吻合。通过控制不同的凝固工艺参数对钢锭进行模拟,得出了不同条件下的微观组织形貌。综合分析可知,在冷却水系数为4000W/(m~2·k),浇注温度为1400℃时对铸锭采取浇注凝固能获得比较好的微观组织的形貌。因此,采取Procast中的微观组织模拟可以对实际的凝固组织起到一定的预测作用以及可以通过此模拟确定在凝固时需要采取的一些工艺参数。更多还原

【Abstract】 Application method to simulate the high nitrogen steel microstructure of solidification process,the simulation results tallies well with the experimental results.By controlling different,to simulate the solidification process parameters on the ingot microstructure morphology under different conditions are obtained.Comprehensive analysis shows that the cooling water coefficient is,the initial casting temperature of 1400°C for ingot casting solidification can obtain better microstructure morphology.Therefore,taking the Procast,can be on the actual organization of solidification microstructure simulation can play a role as well as determined by the simulation need to take some of the process parameters during solidification.更多还原
