4-High Rolling Mills | Metal Processing Machinery ...

4-High Rolling Mills. Four-high rolling mills can be put in tandem, two to seven stands, instead of a reversing mill. They can be equipped with load cells to tell the separating force and hydraulic or mechanical screw downs, depending if it is hot or cold rolling. Sometimes mechanical screw downs are preferred when there is a risk of fire.

How important is sheet and plate steel flatness?

What Is Temper Passing? Temper passing is compressing flat steel under very high pressure between two work rolls to flatten and elongate it (see Figure 2).A cold reducing process, temper passing (also called temper rolling or temper pass) strives to decrease the material thickness between 1.5 and 2 percent (alternatively, elongating the coil 1.5 to 2 …

Why Skin Pass Mill is necessary for Hot Strip Mill

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.
