摘　　要：采用有限差分法，建立了板带热连轧生产过程中温度变化的二维预报模型。用此模型对本钢现场轧制工艺进行了温度变化的解析计算，其结果与实测值相符。在此基础上经过模拟计算，通过回归得到卷取温度的简单预报公式，其预报值与现场实测值吻合甚好。AbstractAtwo-dimensional temperature prediction model for hot-strip rolling process has been develo- ped by using fin ite difference method.The calculations of temperature variation for the actu- ral strip-rolling process at Benxi Iron & Steel Co.have been carried out following this model,and the calculated values show good agreement with the measured ones.Based on the calcula- tion,a simple formula to predict coiling temperature has been obtained by regressions.which is identical with the measured values in the actural process.
