Influence of Rolling Lubrication on Self-Excited Vibration in 1420 Continuous Cold Rolling Mill

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.
