提高热轧轧制润滑投入后轧制稳定性分析

Analysis of Improving the Rolling Stability of HSM After Roll Lubrication Used

宝钢热轧制油油品经过改良以后,降轧制力效果明显,但是投入以后较易发生活套抬高(起套)以及厚度波动等现象,阻碍了轧制油的投入。通过对起套和厚度波动的原因进行分析,采取调整AGC和活套对主传动的调节速度等措施有效减轻了上述现象,提高了轧制润滑的使用率,降低了轧辊的辊耗和轧机的电耗。

The reduction of roll force is very obvious after the improving of rolling oil quality in baosteel HSM,but it is going with some phenomena,like loop rising and thickness reducing and so on,impacting the inputing of lubrication.This article analyzed the reason of loop rising and thickness reducing and improved the stability by adjusting AGC and the addition speed of loop to MRG..As these method were used,the stability is improved and reduction consume of the roll and current.
