描述了板材生产过程中的重要工艺设备张力拉矫机自动控制系统结构、原理、通道控制字和通讯电文结构。分为三级控制 ,生产线工艺段各工艺设备之间的协调控制 ;拉矫机内各单元设备的协调控制和各单元设备的控制。拉矫机 4台电机都采用速度控制 ,补偿电机的速度通过行星齿轮变速箱叠加到主电机速度上 ,用以稳定拉矫机内部张力和延伸率
The structure, principle, channel control word and communication message structure of the tension control and straightening machine automatic control system for the important process equipment in the sheet production process are described. Divided into three levels of control, the production line process section of the coordination between the control of process equipment; straightening machine straightening machine coordination and control of all units of equipment and control of the unit. Straightening machine 4 motor speed control are used to compensate the speed of the motor through the planetary gearbox superimposed on the speed of the main motor to stabilize tension straightening machine internal tension and elongation
