摘　　要：本文依据冶钢连铸机具有条件和GCr15钢的热物理参数,建立了连铸坯凝固数学模型,经过坯壳温度和坯壳厚度的双重验证,证明模型实用。用该模型研究了主要工艺参数对连铸生产及铸坯质量的影响,优化了GCr15钢连铸的最佳工艺参数。According to the particular conditions of the contiuous caster in Yegang and the thermai-physical parameters of GCr15, this paper has established a mathematical model of solidification, which has been proved useful by dual testing on the temperature and thickness of the shell. And it has been applide to study the effect of main technological parameters on the continuous casting production and the quality of billet. The optimum technological parameters have been obtained by optimization in continuous casting of GCr 15.
