摘　　要：某热轧厂平整线生产热轧商品材SPHT2,连续发生厚度不合9卷,造成批量性尺寸改判。通过现场生产情况的排查,重新模拟当时的生产过程,发现此批量性厚度不合的现象,与该机组的平整辊压力有密切关系。通过分析计算,得出平整线压力与厚度、宽度变化的一般方程。对今后热轧卷的尺寸把关起到重要的预警作用。9 of commercial coils SPHT2 produced on the leveling line of a specific hot rolled mill happened to be differential in depth consecutively leading to dimension reclassification of a whole batch. By way of check and examination on-site and simulation of the production conditions it＇s discovered that the deviation of thickness of the batch relates to the pressure of flattening rolls. Through analysis and calculation the universal equation of relations between pressure of flattening rolls, depth and width is derived. It is of great importance in forecasting coils dimension.
