摘要
通过数值计算方法,建立了镇静钢锭热过程的数学模型,并通过现场的实际测定对其进行了修正。在模拟计算中,选用固相线温度做为冶金指标,综合考虑了模铸系统参数及浇注工艺参数,评估了帽口和发热剂设计及浇注工艺对钢锭凝固的影响。
Based on numerical methods, a mathematical model of two-dimensional unsteady heat transfer is developed to simulate the heat transfer of killed ingot, and verified by the experiment measurment in a factory. In the model, the temperature of the solidus is a metallurgical index, and the parameters of system and operation are considered. So it is possible to consider the effect of cap section, heat agent, and operation on killed ingot solidfiction in the whole.
