中厚板轧线的坯料出炉时间控制

Slab Discharging Time Control for Plate Rolling Line

针对中厚板轧线,研究了在实行控制轧制工艺时,如何对坯料的出炉时间进行合理控制,以满足多坯交叉轧制过程轧制节奏控制的需要.介绍了典型单机架中厚板轧线的设备布置情况,并根据不同交叉轧制情况下的轧制节奏控制状态确定坯料之间的轧制间隔时间;根据具体轧线布局计算坯料的出炉运输时间,并确定坯料的出炉剩余时间.考虑其他非理想状况的影响因素,设置坯料出炉剩余时间极限值,实际控制中通过调整该值,保证坯料出炉时间控制的最佳效果.

Investigates how to control reasonably the slab discharging time for plate rolling line to meet the requirements for scheduling a multi-slab alternate rolling process. Describes the typical layout of a single-stand plate rolling line and according to the scheduled rolling rhythm for the process, the time interval between two rolling operations is given. The conveying time after slab discharging is calculated according to the layout of rolling line, with the remaining time after discharging also calculated. A limit value is set up for the remaining time to consider unexpected influencing factors, which can be readjusted in actual operation to optimize the control effect of slab discharge time.
