Influence of Rolling Lubrication for Self-Excited Vibration on Tandem Cold Rolling Mill

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 from650 m/min to above 900m/min. The important problem disturbing the mill was accordingly resolved.
