首钢中小型厂在轧制小型材过程中,由于轧机转速、钢坯温度、轧机孔型磨损等因素的变化,经常影响轧机之间的张力,而张力的变化又直接影响钢材的径向尺寸,以致影响钢材质量。为解决生产中这一关键问题,首钢自动化所、钢研所与中小型厂一起,在学习国内外经验的基础上,经过三年多的努力,终于试制成功满足连轧机工艺要求的活套 Shougang small and medium-sized plant in the process of rolling small sections, due to rolling mill speed, billet temperature, mill hole wear and other factors often affect the tension between the rolling mill, and tension changes in turn directly affect the radial size of steel, so that Affect the quality of steel. To solve this key issue in production, Shougang Automation Institute and Steel Research Institute, together with the small and medium-sized factories, have finally completed trial production of the looper which meets the requirements of the continuous rolling mill after more than three years of hard work
