摘 要:对安阳钢铁集团有限责任公司无缝钢管厂的直流传动拔管机的速度控制系统进行了改进,实现了低速咬入、高速拔制的速度自动控制。实践表明,该项改进提高了拔管机的机时产量,减少了钢管断头,提高了成材率。该技术也可用于交流传动的拔管设备。Modification was made to the speed-control system of the DC driven pipe-drawing mill at the seamless steel tube division of Anyang I & S Group Co.,Ltd.,and now the said modified system is capable of automatic speed control of the mill in a mode of low-speed biting and high-speed drawing. Relevant operational practice has shown that thanks to the said modification,the mill's productivity is increased,tube end-breaking rate is reduced,and yield is heightened. The technique is also suitable for AC driven pipe-drawing mills.
