Cold Reduction. Finishing mills will roll cold coils of pickled hot-rolled sheet to make the steel thinner, smoother, and stronger, through applying pressure, rather than heat. Stands of rolls in a cold-reduction mill are set very close together and press a sheet of steel from one-quarter inch thick into less than an eighth of an inch, while ...

After cold rolling, the specimens were annealed at temperatures of 900°C, 950°C, and 1025°C for 180 seconds and then water quenched to freeze the microstructure.

The hot-rolled, pickled coils incoming to the cold reduction mill have to have excellent quality attributes. The pickling operation must be well-controlled to assure that all the oxides formed during hot rolling are removed. The thickness of the hot-rolled strip is important in that the properties of the final cold rolled and annealed product ...
