The article presents the formulas for calculating the grease layer height at inlet dia of deformation zone, depending on cross-roughness of the rolls and the strip. Analytical solutions covering the fields of all gripping angles of cold rolling process take into account the effect of the grease layer height on the strip in front of the rolls. Explanations are offered on how to calculate the grease layer height when roughness can be neglected, i.e. when it reaches an ideal smooth surface, and when the grease layer height on the strip in front of the rolls can be neglected.

The formulas relating to the laminar flow of grease and isothermic conditions of cold rolling process seem to be unique, as far as data from literature are concerned.
