The process always starts with hot rolling. Hot rolling refers to the process of rolling steel at a temperature typically above 900 °C, greater than its recrystallisation temperature. This allows steel sheets to be made in larger, thicker sizes, ideal for the manufacture of railway rails, large beams, or girders. Hot rolling vs. cold rolling.
Features. Characteristics of Rolling Mill. The frame with integral casting has high rigidity and the rolling force acts radially on each section of the frame. 2. The work roll has a small diameter and the pass reduction rate is high, up to 60%. Some materials can be rolled into very thin strips without intermediate annealing. 3.
