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

In rolling mills, the mass flow control always requires a combined thickness measurement and velocity measurement. Mass flow Automatic Gauge Control (AGC) is a technique used for many years to control strip thickness in tandem cold rolling mills, enabling tighter control of thickness by providing faster and more accurate control of the roll gap.
