Method and system for controlling lateral bending of outlet plate blank of hot rolling fixed-width press

The invention discloses a method and a system for controlling lateral bending of an outlet plate blank of a hot rolling fixed-width press, and the method comprises the following steps: when the plate blank is laterally bent out of the fixed-width press, controlling the center lines of a transmission side hammer head and an operation side hammer head to deviate a set value towards the direction opposite to the lateral bending direction of the plate blank; and the billets with lateral bending are straightened through the deviated transmission side hammer head and the deviated operation side hammer head, and straight billets are obtained. According to the method, the offset of the hammerhead of the fixed-width press can be controlled in real time, lateral bending caused by offset of the hammerhead can be effectively avoided, and the rolling qualification rate is increased. 本发明公开一种控制热轧定宽压力机出口板坯侧弯的方法及系统，其中方法包括：当板坯出定宽压力机出现侧弯时，控制传动侧锤头和操作侧锤头的中心线向板坯侧弯相反的方向偏移设定值；通过偏移后的传动侧锤头和操作侧锤头，对出现侧弯的板坯进行矫直，获得平直的板坯。本发明能够对定宽压力机的锤头偏移量进
