Temper and Skin Pass Mill. A temper mill is a finishing equipment that processes steel strips in order to give them added strength and uniform flatness to the surface. The metal forming method at a temper mill involves rolling steel strips through a cold reducing process or temper pass. This increases the density of the steel by reducing its ...
The Skin Pass/Temper Mill is a key machine at the heart of modern metal strips manufacturing. This mill is key in achieving the desired mechanical properties and surface qualities for a broad spectrum of materials, including, but not limited to, low to high carbon steels, advanced high strength steel, semi-processed silicon steel, stainless steels, …
Main data. Our offline skin-pass mills for carbon steels are stand-alone rolling plants. They usually follow the batch-annealing stage and offer high versatility for processing both hard and ultra-mild strip. The 4-high stands accommodate work rolls in various diameters to apply different rolling forces.

Our solution for hot strip skin-passing is a mill in 4-high design – optionally with CVC® plus – complete with coil preparation station and pay-off ...
1. A wet skin-pass rolling method for rolling a steel sheet (17) by a mill (11) while adjusting the hardness of a product steel sheet (17) through a control of the rolling reduction, characterised in that the method comprises determining an upper limit value (γ u) and a lower limit value (γ &litre ) of an allowable reduction ratio (γ) from a predetermined …
in skin-pass rolling, these two parameters actually have the same value. e=(l1 – l0)/l0 (1) r=(t0 – t1)/t0 (2) Strip tension was also applied to samples during rolling to better reproduce the industrial skin pass process. The laboratory mill was thus modified in order to impart the desired reduction of section, • 10s-1

Skin-pass rolling (or temper rolling) is usually the final process in the production of cold-rolled steel sheets. One of the main objectives in skin-pass rolling is to obtain a certain surface roughness profile. When elongation is small, the effect of lubrication is not observed in elongation and roughness transfer.
One option is to use cluster rolling mills for skin pass operation (using small roll diameters), which are often not available in-house. A second option would be to invest in a major …
