In a pulpit above the rolling mill floor, the operator positions your billet for reduction in the three-high heavy roughing mill. Through a series of cameras and mirrors, the operator closely monitors the billet until the billet reduces to a 2.250 inch diameter. Out of the roughing mill, your bar reheats through another induction heating line to boost the temperature 100 to 500F before
