叙述了热轧卷取机夹送辊的“零电流控制”原理，及在太钢热轧卷取机调试中将原由日本引进的抬上夹送辊的控制方式改造成“零电流控制”，这样，避免了精轧末架抛钢时在卷取机上的夹送辊下降对带钢表面的冲击。这种改造在武钢是成功的，在太钢移植改造也收到了良好的效果
The principle of “zero current control” of pinch rolls in hot coiler is described. In the debugging of TISCO hot rolling coiler, the control mode of the upper pinch rolls imported from Japan is changed into “zero current control” In this way, the impact of the lowering of the pinch rollers on the coiler on the strip surface during the finishing of the finishing frame is avoided. This reform is successful in WISCO, TISCO transplantation also received good results
