After the hot steel bar exits the mill's roughing stands, it is never in more than one roll stand at any time. This is vital to hot rolling non-symmetrical shapes because it allows the bar to spread into the required shape that has been contoured into the roll design. A typical semi-finished billet exits the furnace at 2300º F.
