Cold Mill - an overview | ScienceDirect Topics
A reversing, single-stand, cold reduction mill can be considered similar to the first stand of a tandem mill. Without instrumental control a great deal of skill is required to achieve uniform lateral and longitudinal thickness using a combination of screw-down on the reducing rollers and tension between the reducing rollers and the wind-on reel.
What Is a Temper Mill? (with picture)
A temper mill is a finishing facility that processes steel in the form of sheet and plate in order to give it added strength and uniform flatness to the surface. The metal forming method at a temper mill involves rolling the sheets of steel through what is known as a cold reducing process or temper pass. This increases the density of the steel ...

Temper Passing | Metal Processing Machinery | American Steel
A temper mill is also used to make cold rolled after annealing to assure a consistent quality. After the material is made hot rolled, it needs to be pickled and cold reduced. Cold reducing increases the yield strength and the material can be too hard to be used for any type of deep draw work or accurate bending.
