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.

A reversing mill is a rolling mill in which the workpiece is passed forward and backward through a pair of rolls. The reversing mill is so named because the steel runs back and forth between the rollers, reducing the thickness incrementally with each pass.

Iron-carbon phase diagram 1. At low temps and to the right of the solubility limit line, αferrite and iron carbide (Fe 3C) coexist. 2. From 727°C to 1148°C, the solubility of carbon in the austenite increases from 0.77 to 2.11%. The solubility of carbon in austenite is greater than in αferrite because of the FCC structure of austenite. 3.
