Difference Between Hot and Cold Rolled Steel Metal

Sep 11, 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.

Cold rolling SMS group

There is almost no end to the uses of high-grade steel strip in today's world. They include everything from aircraft to beverage cans. That explains why we design our cold rolling mills to be just as versatile. What's important to you are not only high flexibility and product quality, but also sustained, cost-effective operation of your plants.

Steckel mill Wikipedia

A Steckel mill, also known as a reversible finishing mill, [citation needed] is similar to a reversing rolling mill except two coilers are used to feed the material through the mill. One coiler is on the entrance side and the other on the exit side. The coilers pull the material through the mill, therefore the process is more similar to drawing than rolling.

Steel Billets, bars, and rods Britannica

Steel Steel Billets, bars, and rods: Billets are the feedstock for long products of small cross section. In cases when they are not directly cast by a continuous caster, they are rolled from blooms by billet mills. One method of rolling billets, which are usually 75 to 125 millimetres square, is to use a three-high mill with box passes, as shown in A in the figure.

Rolling Process SlideShare

• Rolling is the most widely used forming process, which provides high production and close control of final product. •The metal is subjected to high compressive stresses as a result of the friction between the rolls and the metal surface.Rolling process Note: rolling processes can be mainly divided into 1) hot rolling and 2) cold rolling. 3.
