    IMPROVEMENT OF AUTO SPEED-CONTROL SYSTEM OF PIPE-DRAWING MILL

    • 摘要: 對(duì)安陽(yáng)鋼鐵集團(tuán)有限責(zé)任公司無(wú)縫鋼管廠的直流傳動(dòng)拔管機(jī)的速度控制系統(tǒng)進(jìn)行了改進(jìn)，實(shí)現(xiàn)了低速咬入、高速拔制的速度自動(dòng)控制。實(shí)踐表明，該項(xiàng)改進(jìn)提高了拔管機(jī)的機(jī)時(shí)產(chǎn)量，減少了鋼管斷頭，提高了成材率。該技術(shù)也可用于交流傳動(dòng)的拔管設(shè)備。

       

      Abstract: 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.
