Skin Pass Mills The device uses skin pass rolling to improve the mechanical properties and surface texture, and improve flatness, in order to form materials such as hot-rolled steel sheets, cold-rolled steel sheets, stainless steel plates, and aluminum plates into final products.
Moreover, the larger diameter of real skin-pass rolls increase the contact length between sheet and roll and, therefore, the sliding length per rotation. Nevertheless the results of this investigation gives reason to expect an enhanced wear performance of laser implanted rolls in a skin-pass or even tandem mill application.

ment length of 12.5mm. The similar skin-pass rolling experiment was conducted with another laboratory rolling mill with a small work roll of 100mm diameter (R50 in the following figures) to evaluate the effect of work roll size. After the experiments of skin-pass roll-ing and simple compression, the surface roughness on
Tags Pickle Lines, Rolling Mills; Temper Pass or Skin Pass Rolling. Material can be reduced accurately while skin passing. Hot rolled steel coming from a steel mill or pickle line may need to be reduced 1% to 2% in thickness. This can be done on a coil-to-coil temper pass mill or in line on a cut-to length line.

control of a 4Hi skin pass mill using the leveling position, work roll bending force (bending force), and rolling force as MVs. Although rolling force is expressed as the result of rolling, it can be treated as a MV by the minor control loop, which adjusts the roll gap so that the rolling force achieves the set value.

The influence of skin pass rolling on tensile and microstructural properties of three industrial grade steels was investigated. Skin pass rolling was performed on a laboratory mill equipped with a device designed to reproduce the effects of sheet tension and with load cells aimed at measuring the main working parameters.
Due to its higher rolling forces, the 6 high UCM-Mill is the preferred skin-pass mill solution to meet the continually increasing demands placed on strip flatness, elongation and roughness, especially for hard-material grades. Technology Automation Integrated Plants & Solutions Technology Packages

The hot-rolled strip skin-pass mill is the important technological equipment of finishing process in the hot rolling plant, and its role is to apply a slight thickness reduction of approximately 1% - 4% to the finished products cooled to room temperature to repair flatness defects and improve the surface quality and mechanical properties. In this study, the initial flat roll contours were ...
Skin-rolling, also known as a skin-pass, involves the least amount of reduction: 0.5–1%. ... To minimize the roll diameter a four-high or cluster mill is used. A small roll diameter is advantageous because less roll is in contact with the material, which results in a lower force and power requirement.
