摘　　要：建立了一维非稳态连铸圆坯凝固传热数学模型.运用有限差分法求解并编制了计算机程序。经与实测数据比较,模型具有可靠性。可运用此数学模型预报连铸各参数的冶金效果,如铸坯的温度场、液芯长度、凝固壳厚度等。A mathematical model for heat transfer in course of CC round billet solidification was established. The model ,consisting of a one-dimensional unsteady conduction equation and boundary condition equations,has been programmed for computer solving. The calculated values of solidification profiles and surface temperature are in agreement with experimental ones reported. This model is aimed at forecasting the metallurgical effects of various CC process parameters, such as temperature field, liquid pool deepness and solidification profile.
