摘　　要：中间包温度是影响连铸板坯凝固位置的重要因素之一。作者对中间包温度变化引起的板坯凝固时间变化进行了分析,提出了一种对中间包温度变化引起的铸坯凝固位置变化进行预测的方法。将预测结果用连铸热传导计算系统进行检验,检验结果说明了该预测方法的合理性。基于预测和分析结果,提出了相应的动态轻压下控制策略,并将其应用于实际动态轻压下模型控制系统。The tundish temperature is one of the factors which seriously affect the solidification position of continuous casting slab. The tundish temperature fluctuation causes the change of time spending on slab solidification. The variation of solidification time was analyzed, and then the synchronous change of solidification position was predicted by a newly presented method. The prediction method was tested in a heat conduction computation system of continuous casting and the results illustrated the validity. Based on the prediction and analyzing results, the corresponding control strategies were proposed and applied into a practical dynamic soft reduction model control system.
