对平面形状控制理论模型进行简化，将厚度变化区间内厚度变化量与长度简化成线性关系；应用考虑全粘着条件的前滑模型，通过离散化处理计算楔形段轧制过程时间；确定平面形状控制参数，并进行极限值的检查修正。在现场成功实现平面形状控制功能，获得较好的效果。

The theory control model for the plan view pattern control function was simplified; the relation between the thickness and the length of the taper was simplified and a linear relationship was obtained. Using the forward slip model with the adhesion condition, the taper rolling time can be calculated by discrete treatment. The control parameters can be got and the results should be checked and be corrected if over limit. The plan view pattern control function had been used onsite, and better effect had been got.
