The Hot Rolling Process - California Steel

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.

ROLLING FLAT AND SHAPED WIRE

The process of rolling is mainly used for either ferrous or nonfer-rous metal stock and is classified into cold, warm, and hot rolling of wire or sheet. This chapter primarily covers the cold rolling of flat and shaped wires. Flattening as the basic rolling operation for sheet or wire uses two cylindrical rolls with parallel axes (see Fig. 1).

Rolling (metalworking) - Wikipedia

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.

What is "Cold Rolling" Stainless Steel and Other Metals ...

In simple terms, cold rolling is the process of strengthening steel by changing its shape without using heat. Cold rolling, unlike hot rolling such as with hot rolled steel, can only occur when a metal is below its re-crystallization temperature. Where hot rolling is performed using high temperatures, cold rolling is performed at room temperature.
