【摘要】 针对1420冷连轧机组第5架轧机轧制过程中发生的自激振动问题,从理论上分析了轧制润滑与轧机自激振动之间的关系。通过优化轧制润滑工艺参数,抑制了该机组第5架轧机的自激振动,使轧机稳定轧制的临界轧制速度从原来的650 m/min提高到900 m/min以上,解决了困扰该机组生产的一大难题。更多还原

【Abstract】 On account of the self-excited vibration in No.5 stand of 1420 cold rolling mill,the relationship between rolling lubrications and self-excited vibration of rolling mill was theoretically studied.The self-excited vibration in No.5 stand of the mill was restrained by optimizing the lubrication technical parameters,and the critical stabilized rolling speed was increased from 650 m/min to above 900m/min.The difficult problem affecting the quality of rolled product was accordingly resolved.更多还原
