Steel Hot Rolling Mill Application Overview

The Hot Rolling Mill is used to reheat shapes of steel to soften them enough so that they can be rolled thinner and longer through a series of rolling stands. The finished product can be either a strip, plate, rod, bar, wire, or shape rails and H-beams. After the steel is formed to its desired shape, it is cooled so that the desired mechanical properties of the steel product are achieved.
