Cold Rolling Mill – Ferro Gilan Complex

Cold Rolling Mill. Cold 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.

Strip Coil - Stainless Steel, Nickel Precision | ESM-Hampshire

The result is that when hot-rolled steel cools, it shrinks slightly, so there is less control of the final size and shape of the finished product, compared to cold-rolled steel. Creating strip steel necessitates further processing in cold reduction mills, where the material is cooled at room temperature followed by annealing and/or tempers rolling.

Cold Rolled Steel – Berlin Metals

The thickness of the hot-rolled strip is important in that the properties of the final cold rolled and annealed product is influenced by the percent of cold reduction. This means that the thickness of each hot-rolled coil is carefully controlled to provide the mill with a specific thickness to achieve the proper percent cold reduction.

Hot-Rolled Steel vs. Cold-Rolled Steel

Mar 27, 2020· The pros and cons of hot-rolled steel come down to strength versus price. Hot-rolled steel is weaker than cold-rolled, but it's also cheaper since it doesn't go through the second production process. However, this doesn't automatically mean cold is better just because it's stronger and more expensive.
