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.

BlueScope Steel Cold Rolled products are generally trimmed to customer width. However, when coils are being slit to narrower widths, untrimmed (or mill edge) processing and tolerances may be suitable. AGEING Nonageing, or stabilized steels do not experience a yield point reappearance during storage. Stretcher strain markings

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). At the ...

No. 2B Finish is a bright cold rolled finish commonly produced in the same manner as No. 2D, except that the final light cold rolling pass is done using polished rolls. This produces a more reflective finish that resembles a cloudy mirror. Finish reflectivity can vary from manufacturertomanufacturer and coiltocoil with some coils looking quite mirrorlike and others being fairly dull. No ...
