    Corrosionpedia What is Hot Rolling? Definition from

    Hot rolling is a metalworking process in which metal is heated above the recrystallization temperature to plastically deform it in the working or rolling operation. This process is used to create shapes with the desired geometrical dimensions and material properties while maintaining the same volume of metal. The hot metal is passed between two rolls to flatten it, lengthen it, reduce the cross sectional area and

Hot & Cold Working and the Rolling Process

Endless Hot Strip Rolling Process In conventional hot strip production, slabs of thickness of about 250mm are heated in a furnace and are reduced to 30 to 60mm in thickness after passing through the roughing mill, and then further reducing it to within a range of 0.8 to 25.4mm by rolling in the finishing mill.

Understanding Rolling Process in Long Product Rolling Mill

Nov 27, 2015 · During the hot rolling of steel, heat is transferred to the rolls. If not cooled, the heat buildup causes increase in the temperature of the roll to a temperature equal to that of the stock being rolled. At this stage the roll would also undergo plastic deformation. To remove the heat from the roll, cooling water is applied.

For steels, hot rolling is generally conducted at 850–1200 °C, in the austenite phase, while for aluminum it is conducted at 350–500 °C. During each rolling pass, strain is imparted to the material which causes an increase in dislocation density and consequently work hardening.

In addition to producing a useful shape for further processing, the hot rolling process converts the cast grain structure into a wrought grain structure. The initial cast material will possess a non uniform grain structure, typically large columnar grains that grow in the direction of solidification.
