14/01/2017 · Mill spring causes the thickness of the strip exiting from the rolling mill to be greater than the roll gap set under noload conditions. Precise thickness rolling requires the elastic constant of the mill. Calibration curves are needed. The elastic constants are usually in the range of 1 GNm1 to 3 GNm1 for screwloaded rolling mills and around 4 GNm1 for hydraulically loaded mills.

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. Therefore, most cold rolled after reducing must be annealed. The annealed product ...

11/09/2014 · Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel's recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes. Hot rolled steel is typically cheaper than cold rolled steel due to ...
