Cold Rolled Tempers. Cold working of copper and copper alloys, by rolling or other methods, will increase both tensile strength and yield strength in a very predictable manner. Most copper alloys are produced to a series of cold-rolled tempers with a tensile strength range unique to …
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
Sep 11, 2014· Customers often ask us about the differences between hot rolled steel and cold rolled steel.There are some fundamental differences between these two types of metal.The differences between hot rolled steel and cold rolled steel relates to the way these metals are processed at the mill, and not the product specification or grade.
In the as cast form it is called electrolytic tough pitch (ETP) copper. The structure of the as-cast material is similar to that described above. When the as-cast ETP copper is hot rolled the eutectic structure is completely destroyed. The microstructure of the hot rolled copper contains many small grains.

Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.

Hot-rolled vs Cold-rolled Steels. There are two distinct forms of plate and sheet steel available for the various alloys of carbon steel: hot rolled and cold rolled. Hot rolled steel has a course, grainy surface with dark streaks. This grainy texture is the result of removing the deep scale during the pickling process.
The requirements on the flatness of the plate and sheet products sold by Rolled Alloys vary considerably by the type of product, by alloy, by thickness and by the size of the piece. AMS and ASTM standards exist which cover the flatness requirements for most plate and sheet items as produced by the mill.
