摘要:
根据热型连铸技术原理,充分考虑冶金单元三传过程,对一些微小部分传热做了近似计算,建立了热型连铸凝固过程二维稳态温度场的物理、数学模型.编制了计算铸型出口温度、冷却距离、拉铸速度和喷水冷却强度等工艺参数应用程序,并在VC++6.0环境下迭代运行,理论上得出了以上工艺参数对铸坯固液界面位置的影响程度.做了多次纯铜热型连铸实验,计算结果与实验所测数值及文献上报道的实验结果吻合较好,同时也说明了该二维模型的正确性.
Abstract:
According to the principle of thermal continuous casting technology, fully considering the three-way transmission process of metallurgical unit, the heat transfer of some small parts was approximated, and the physical and mathematical models of the two-dimensional steady-state temperature field of the solidification process of thermal continuous casting were established. The application of process parameters such as calculating mold outlet temperature, cooling distance, drawing speed and water spray cooling intensity was compiled, and it was iteratively run in the VC++6.0 environment, and the influence degree of the above process parameters on the position of the solid-liquid interface of the casting billet was theoretically obtained. A number of pure copper hot type continuous casting experiments were carried out, and the calculation results were in good agreement with the measured values and experimental results reported in the literature, and also showed the correctness of the two-dimensional model.
