IMPROVEMENT ON THE ROLLING FORCE MODEL OF THE SKIN PASS

In consideration of that the stress and deformation distribution was uneven in the direction of strip thickness, therefore, Karman's plane assumption wasn't adopted. A set of new improved model of rolling force for the skin pass was established by the relevant equilibrium differential equation with the boundary condition of contacted surfaces. Get price

Skin

The most common configuration is a single skin-pass mill that rolls in a single direction, with tension reels placed at both ends of the mill. However other types are also used, such as a temper mill with two mill stands for higher tempering in tin-sheet production mills which include DCR (Double Cold Reduction) mills with two or even three mill stands for rolling thin tinned materials known as DR Get price

Skin Pass Rolling of High Manganese Steels

Applying a specific roughness on steel sheets, to ensure paintability and sufficient lubrication, is a crucial point for the metal forming processes. Due to the strength of high manganese HSD steels (X70MnAlSi 15-2.5-2.5), special actions are necessary to obtain the required roughness. At Salzgitter Mannesmann Forschung skin-pass rolling experiments on high manganese HSD steels with Get price

The change of work roll surface topography during skin

Sep 14, 2015– This paper aims to analyze changes in the surface topography of the work rolls during skin passing. Cold rolled steel sheets are additionally subject to skin pass rolling to form an appropriate surface topography.
