Cold Rolling and Annealing. Cold Reduction Mill The hot rolled pickled and oiled band must now be further reduced into lighter gages. This is performed on a tandem cold reduction mill. These mills consist of a series of 5 or 6 stands with rolls 4- or 6-high set in tandem. As the strip passes through the mill, it is continuously reduced.

If you search the Internet for what a cold-rolling mill is, one might be hard-pressed to find a description to relate to and understand. It is important to preface that what is involved in the process of re-rolling aluminum coil or strip is quite capital intensive, which explains why there are limited mills in the United States that will flat roll aluminum coil.

What Is A Rolling Mill? In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.

Temperature Monitoring. Temperature Control in Hot Rolling Mills. Hot Rolling Mills are used to reheat shapes of steel to soften them enough so that they can be rolled thinner and longer through a series of rolling stands. The finished product can be either a strip, plate, rod, bar, wire, or shape (rails and H-beams).

The idea to use temper-pass rolling mills in conjunction with leveler, cut-to-length lines was not addressed until the late 1980s when Robinson Steel successfully installed its first line. This integration allowed the steel processor not only to remove inherent rolling stresses but also to remove coil set more easily.
