轧钢机通常使用压下装置来控制一定的板厚,但由轧辊偏心而引起的板厚误差是不能控制的。由于轴承及轧辊的机械加工技术上的限制,轧辊的偏心是不能完全克服的,所以该装置把偏心量变换成电信号进行统计处理,使偏心引起的板厚误差控制在最小范围,即由压延负荷信号取出偏心量,把补偿信号送给压下控制装置。 其方法如动作图所示,压延负荷随压延速度、板
Rolling mills usually use a pressing device to control a certain thickness, but the thickness error caused by eccentricity of the rolls can not be controlled. Due to the technical limitations of the machining of the bearing and the roll, the eccentricity of the roll can not be completely overcome. Therefore, the device converts the eccentricity into an electrical signal and performs statistical processing to control the thickness error caused by the eccentricity to a minimum extent, that is, Take out the eccentric load signal, the compensation signal to the pressure control device. The method as shown in the action diagram, rolling load with the rolling speed, plate
