Skin-Pass Mill Solutions by Primetals
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

Substitution of chrome plating for the rolls of
The aim of the CrFreeRolls project to find a solution to a threat arising in cold rolling and especially in skin-passing. For long hard chrome plating has been introduced to enable high consistency of the roughness of the strip after skin-pass. This result is obtained owning to the hardness and the high wear resistance that is given by chrome plating.This technique proved to be very efficient

Cold Rolling - an overview | ScienceDirect Topics
Cold rolling reduction is an important factor that affects drawability of IF steel. It has been observed that increasing cold rolling reduction increases the r m value, at least up to 90% [34].This effect has been shown in Fig. 5.14.Perhaps the most important parameters in the production of a strong {111} recrystallization texture are the annealing temperature and the time of holding [35].

Temper Passing | Metal Processing Machinery |
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. Many automobile and truck blanks made from hot rolled steel are from laser and
