为了提高张力控制精度,对冷轧退火机组开卷机钢卷内径和外径的计算方法进行研究,包括建张时使用的基于长度检测的卷径计算方法和穿带、甩尾时使用的基于理论的卷径计算方法。通过3个典型的卷径计算错误,分析故障产生的原因,并提出相应的处理方法,有利于指导实际生产运行。
In order to improve the precision of tension control, the calculation method of the inner diameter and the outer diameter of the uncoiler of cold rolling annealing unit is studied, including the method of calculating the diameter of the coil based on the length detection used in Jianzhang and the theory based on theory Volume diameter calculation method. Through three typical calculation of coil diameter errors, analysis of the reasons for the failure, and put forward the corresponding treatment, is conducive to guiding the actual production operation.
