通过对冷轧的基本原理的分析,讨论了测定冷轧过程中的变形参数,运动学参数和力能参数,用轧制理论公式算出延伸系数、单位轧制压力和摩擦系数等作为冷轧润滑试验中的主要评定指标。文章还提出了延伸压力系数这一概念,综合考虑了轧制压力和延伸系数的相互影响,可以更完整地反映出冷轧润滑试验中润滑剂的效果。 Through the analysis of the basic principle of cold rolling, the deformation parameters, kinematic parameters and force energy parameters in the cold rolling process are discussed. The elongation coefficient, the unit rolling pressure and the friction coefficient are calculated by the rolling theory formula as the cold rolling lubrication The main test indicators. The article also proposed the concept of extended pressure coefficient. Considering the interaction between rolling pressure and elongation coefficient, the effect of lubricant in cold rolling lubrication test can be more completely reflected.
