  • Hot Rolling an overview ScienceDirect Topics

    During hot rolling the microstructure and mechanical properties of the material change with its thermomechanical state, determined by composition, percent reduction, strip thickness, strip speed, and heat transfer. 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.

  • 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
