- 摘要:
- 研究了拉速和过热度相关工艺参数对铸坯温度场的影响规律,利用Fluent软件模拟石油套管用钢37Mn5铸坯的连铸凝固过程,分析了连铸坯凝固传热过程的温度场。讨论了不同过热度和拉坯速度条件下铸坯温度场的分布情况。总结了连铸圆坯凝固过程的传热特点,优化了工艺参数。结果表明,优化后的工艺参数可以指导生产实践。
The influence of drawing speed and superheat parameters on the temperature field of cast billet was studied.The solidification process of continuous casting of steel 37Mn5 billet for petroleum casing was simulated by software Fluent,the temperature field of solidification heat transfer process of continuous casting billet was analyzed.The distribution of billet temperature field under different superheat and casting speed was discussed.The heat transfer characteristics of continuous cast round billet during solidification were summarized and the process parameters were optimized.The results show that the optimized process parameters can guide the production practice.
