前言我厂从德国曼内斯曼—德马克—米尔公司(简称M-M公司)引进的张力减径机是我厂新建140无缝管热轧线上的关键设备之一,它是用来将轧管机轧后的荒管再进行无芯棒带张力的进一步轧制,张力减径机采用热轧方式,可以实现减径、减壁、等壁、增壁轧制,由于张力减径机精度高,产品规模范围大,轧制速度高等优点,许多无缝管生产线都选用张力减径机作为最终精轧机,从而进一步提高生产率,提高成材率。产出高质量的无缝钢管。张力减径机调控比较复杂,我们通过对张力减径机传动系统的分析,找到一种比较简单的调控办法,即通过计算各机架轧辊转速,用轧辊转速控制张力,达到控制成品管壁
Preface Our factory imported from Germany Mannessmann - DeMARK - Mill (referred to as MM Company) stretch reducing mill is one of the key equipment of our factory to build 140 seamless hot-rolling line, it is used to rolling Pipe mill after the shortage of pipe and then no core rod tension further rolling, tension reducer using hot-rolled way, you can reduce, reduce the wall, wall, wall rolling, tension reducer accuracy High, large-scale product range, high rolling speed advantages, many of the seamless pipe production line selection of tension reducing mill as the final finishing mill, thereby further improving productivity and improve the finished product rate. Produce high quality seamless steel pipe. Tension reducer control more complicated, we through the tension reducer drive system analysis, to find a relatively simple control method, that is, by calculating the speed of each roll rack, roller speed control tension, to control the finished tube wall
