精密带材在国民经济中的地位日益显著。随着彩色电视的普及和海底电缆的广泛使用,以及大量精密仪器仪表的使用要求,对精密带材的需要量大,要求板幅宽、质量高,使用普通的轧制方法很难轧出合格产品。为了解决这一问题,近年来国外研制一种电液脉冲马达拖动的轧机压下系统。这种压下系统精度高,反应快,易于控制,制造价格便宜,很便于精化各种冷轧机。北京冶金设备自动化研究所1978年开始
Precision strip in the national economy has become increasingly prominent. With the popularization of color television and the widespread use of submarine cables, as well as a large number of precision instrumentation requirements, the demand for precision strip, requiring a wide width, high quality, the use of ordinary rolling method is difficult to rolling qualified product. In order to solve this problem, in recent years abroad developed a electro-hydraulic pulse motor rolling mill rolling system. This depressing system, high precision, fast response, easy to control, manufacturing cheap, easy to refine a variety of cold rolling mill.
