方坯连铸数学模型的工程实用化

On Application of A Mathematical Model of Square Billet Continuous Casting to Engineering

摘要: 通过对方坯连铸过程的分析,建立了二维非稳态凝固传热数学模型。根据铸坯长度约为断面尺度10²倍的特点,选用线上积分法求解,致使模拟计算可用一般的IBM-PC/XT型微机在合理的时间内完成,从而在方坯连铸数模的工程实用化方面取得了满意的进步,可望成为科研、设计和生产现场的有力工具。
文中还列举了一些模拟计算结果。

Abstract: A mathematical model of two-dimensional unsteady solidification heat transfer has been developed to simulate the square billiet continuous casting.Due to the ratio of length to cross section of the billets is about 102, an integral on line is used to complate the simulation with a common computer (IBM-PC).As a result, application of this model to engineering has been made satisfactory.
