Pickle Line where the strip is tightly worked up and down by a series of roll cassettes. Shape defects are removed from the strip as its thickness is reduced by around one-half of one percent. The #2 Galvanizing line includes a 4-hi skin-pass mill stand situated just in front of
SKIN-PASS MILLS for a perfect finish Before skin-passing After skin-passing. 3 Flatness of a skin-passed steel strip. ... skin-pass mills possess hydraulic roll-gap adjustment systems for controlling the roll force and work-roll bending systems for influencing the strip flatness.
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.

Osborn non-woven rolls are being used in all cold strip lines and rolling mills for steel, aluminum, stainless steel and non-ferrous metals. Among them are pickling and annealing lines, coating process, cleaning and degreasing lines, as well as skin-pass mills, to name just a few.
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 .
The main effect of skin pass rolling is to create mobile dislocations and not to reduce the thickness of the strip. The thickness reduction in skin pass rolling is generally under 2 % [2].
A temper mill is a steel sheet or steel plate processing line composed of a horizontal pass cold rolling mill stand, entry and exit conveyor tables and upstream and downstream equipment depending on the design and nature of the processing system.
BWG also built a test rolling mill to conduct basic research and verify equipment design parameters. The EDT skin pass mill is installed in the preparation line and comes into operation at the beginning of the process chain. In addition to the surface enhancement, strip side trimming and surface inspection functions are completed on this line.
1. Introduction. Skin-pass rolling is the final forming step in the production of cold rolled steel sheet. The process has quite different parameter settings than conventional sheet rolling due to small reduction (app. 1%), large contact length compared to the sheet thickness and large roll .
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.
