摘　　要：研究Nb微合金化钢连铸异型坯的高温塑性,根据铸坯的高温塑性,利用数值模拟的方法,确定异型坯连铸二次冷却强度。通过生产实践,铸坯质量有较大提高,说明试验方法正确合理。In this paper the hot ductility of CC beam blank which contains Nb has been studied, and according to the result, the secondary cooling intensity of beam blank CC is determined by mathematical simulation method. The quality of beam blank has been improved in the course of production. It shows that the method is correct.
