The Rolling simulation program for calculating the empty gap unloaded stand. Speed calculation is a function of finishing speed, area of the bar,
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 semifinished casting products, such as slabs, blooms, and billets.
