Hot Rolling - an overview | ScienceDirect Topics

When hot rolling steel in the laboratory, using relatively small rolling mills, values of 420 kW/m 2 K appear to be the correct magnitudes. If modelling hot rolling of steel under industrial conditions, values of 50120 kW/m 2 K are more useful. In both cases, the layer of scale is an important parameter.

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.
