| 摘 要： | 建立了异型坯连铸凝固传热数学模型,并利用有限元法进行离散求解.在此基础上开发了异型坯连铸动态二冷控制模型,模型以5s为周期动态计算整个铸坯实时温度场,并采用有效拉速和表面目标温度法对二冷水量进行设定和优化.用可视化编程工具Visual C++6.0编制了异型坯连铸动态二冷控制系统.在相同工况情况下,动态二冷控制系统仿真结果与大型商业软件Marc计算结果一致,可用于在线控制或异型坯连铸二冷工艺离线设计优化.

| Abstract: | A mathematical model for thermal transmission and solidification of beam blanks was established,and it was discretized and solved by finite element method(FEM).A dynamic secondary cooling control model of beam blanks was developed on the basis of the mathematical model.The dynamic secondary cooling control model can dynamically calculate the entire real-time temperature field of beam blanks with a cycle of five seconds,set up and optimize the amount of water for second cooling by using virtual casting speed... |
