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

SKIN PASS AND DEFECTS - STEEL FEEL

Skin Pass Mill. In this article we will discuss skin pass and defects. Rolling is used to reduced the thickness and to make the thickness uniform. Skin pass is another type of rolling process. Skin pass rolling is defined as a process in which fine structure give to the newly generated grain. After annealing process so that it become useful for forming operation. In case of skin rolling also

Fundamentals of Rolling | ScienceDirect

This book discusses as well the different types of rolls for various rolling mills, including blooming, plate, sheet, sheet bar, small section, heavy product, skin passing, and cold rolling mills. The final chapter explains the purpose of roll pass design to ensure the maximum output at minimum cost as well as to reduce the roll wear to a minimum. This book is a valuable resource for rolling

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].

DMS skin-pass mills - Fives in Steel

Roll change cars for all skin-pass mills. The modern design of this system allows rolls to go through the mill stand or side changing system, depending on specific needs. Combined with a fast roll changer car, this design is the ideal system for a fast and effective roll change and is particularly well adapted to in-line DMS SkinPass mills.

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
