在轧制过程中,轧件的变形抗力增加和摩擦力的增大,是造成轧制压力、电耗和辊耗增加的重要因素。如何减小摩擦力(实质是剩余摩擦力)和降低变形抗力,从变形区力的分析可知,摩擦系数是影响剩余摩擦力和轧制压力的主要因素。本文通过实例说明热轧采用工艺润滑的必要性。 In the rolling process, the rolling deformation resistance increases and friction increases, is caused by the rolling pressure, power consumption and roller consumption increases an important factor. How to reduce the friction (in essence, the residual friction) and reduce the deformation resistance, from the deformation zone analysis shows that the friction coefficient is the main factor affecting the residual friction and rolling pressure. This article illustrates the need for process lubrication by hot rolling.
