Abstract

Based on the method by A.I. Tselikov for calculating the power–force parameters of the cold thin-sheet rolling and the known methods for calculating the power consumption by drum-type coilers and decoilers, a method has been developed for determining the specific power consumption for the reversive rolling considering the tension. According to calculation results, the qualitative and quantitative effect of the tension on the total power consumption has been studied. It has been established that the cold rolling with predominant decoiler tension is always more energy efficient. The modeling of the current rolling schedule has shown that an increase in the decoiler tension from 0.01 (the currently effective value) to 0.2, with respect to the resistance of the metal to deformation, allows for a reduction in the power consumption for rolling on a 1200 reversing mill from 108.5 to 92.5 kW h/t, i.e., by ~15%.

可逆轧机薄板轧制的能耗优化

摘要

基于AI Tselikov的方法来计算薄板冷轧的功率参数以及已知的鼓式卷取机和开卷机的能耗计算方法，已开发出一种方法来确定薄板冷轧机的单位能耗考虑到张力的可逆滚动。根据计算结果，研究了张力对总功耗的定性和定量影响。已经确定的是，以开卷机张力为主的冷轧总是更节能。当前轧制时间表的模型显示，相对于金属的抗变形能力，开卷机张力从0.01（当前有效值）增加到0.2，
