变宽度钢板的轧制方法
摘要：
一种变宽度钢板的轧制方法，中厚板的轧制策略采用纵横纵策略，首先确定成形阶段目标阶梯厚度的尺寸，即计算成形阶段阶梯板较薄部分的厚度和长度，计算展宽阶段目标厚度，计算成形阶段阶梯板较厚部分的厚度和长度；成形阶段尺寸计算完成后，按照常规轧制方法进行成形轧制，将钢板轧制到较厚尺寸，按照阶梯厚度钢板的轧制方法，附加一个或多个道次，将钢板轧制成符合尺寸要求的阶梯厚度钢板；成形阶段轧制完成后，将钢板转钢90度，进行展宽阶段的轧制；展宽阶段轧制完成后，转钢90度，进行伸长阶段的轧制。采用本发明方法，能够以方便快捷的工艺，连续轧制生产变宽度钢板。
摘要（英）：

The present invention relates to a rolling method of variable width steel plate. Said method includes the following several steps: firstly, defining size of target step thickness in forming stage, namely, calculating thickness and length of thiner portion of stepped plate in forming stage, calculating target thickness in widening stage and calculating thickness and length of thicker portion of stepped plate in forming stage; after the calculation of forming stage size is completed, utilizing conventional rolling method to make forming rolling operation. Besides, said invention also provides the concrete rolling steps of said rolling operation.
