摘要

PPROBLEM TO BE SOLVED: To prevent the occurrence of problem on quality that the plate thickness of a material to be rolled deviates, after rolling, from the desired range of values, and to prevent the occurrence of such problems on plate passing that a material to be rolled, which is under tandem rolling in a finish rolling mill, hangs loose and folds between stands to cause the discontinuance of rolling and the breakage of the material to be rolled, by conducting a precise calculation for predicting a thermal crown of the work roll of the finish rolling mill. PSOLUTION: When predicting the thermal crown of the work roll for hot finish rolling during the operation of hot rolling, one or more out of the density, the specific heat, the thermal conductivity, and the linear expansion coefficient of each work roll are reflected on a predicting formula for the thermal crown.

要解决的问题：为了防止出现质量问题，待轧制的材料的板材厚度在轧制后偏离所需的值范围，并防止在板材通过时发生此类问题，在精轧机中进行串联轧制的待轧制材料悬空并在机架之间折叠，通过进行精确的计算来预测轧制的热拱度，从而导致轧制中断和待轧制材料破损。精轧机的工作辊。

解决方案：在热轧操作期间预测热精轧工作辊的热凸度时，每个工作辊的密度，比热，导热系数和线性膨胀系数中的一个或多个反映在热凸度的预测公式上。
