Single or double stand skinpass mills are placed inline at the exit of continuous annealing and continuous galvanizing lines. 6 high UCMMILLs are supplied in response to recent requirements to roll harder material, such as hard tin plate and SS, with .
Reversing Cold Rolling Mill (CRM) Skin Pass Mill (SPM) Reversing Cold Rolling Mill for Stainless Steel
The skinpass is a cold rolling process that provides a small reduction in thickness (below to 2%) of the rolled material (Roberts, 1978). This mechanical process is used to achieve a desired final thickness and flatness of the rolled sheet, while attempting to improve their surface finishes and eliminating Lüders bands ( Lenard, 2013 ).

Why Skin Pass Mill is necessary for Hot Strip Mill ? Lots of necessary functions 1. To get good shape (flatness) 2. To prevent coil break 3. To get smooth surface 4. To adjust coil tonnage to customer''s demand 5. To discard the scrap and secondary portion 6. To inspect coil surface Generally there isnot a hot strip mill without a skin pass mill.
Temper / 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 hotrolled steel sheets, coldrolled steel sheets, stainless steel .
A cold rolling mill consists of different plants and machines. First, the scale that has formed on the hot strip is rinsed in the continuous pickling line. The coils are then prerolled and annealed in a belltype annealing furnace. In the skinpass mill, the cold strip obtains the desired final mechanical and technological properties.

The hotrolled strip skinpass 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 ...
Rolling mills rolls are the prime component of an rolling mill production line. The rolling mill rolls should be of heavy duty and can sustain various wear and tear that is generated in a metal rolling operation which are very common in cold rolling mills and hot rolling mills.
Polytec LSV Laser Surface Velocimeter for recent upgrades on two 4High rolling mills used for reduction skin pass at Hagen, its location in Germany. In this case, each mill utilizes standalone LSV sensors for strip measurement. The application at each roll mill required a set of two LSV''s, one located on either side of the mill.
ment length of The similar skinpass 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 skinpass rolling and simple compression, the surface roughness on
