The primary function of the Hot Rolling Mill in the Aluminum rolling mill is to reheat the semi-finished aluminum ingots to their near melting point and then roll them under extreme pressure to thinner and longer strips of aluminum. The roll's design and pressure applied to the aluminum ingot varies from one hot rolling mill to the next.
