Six-high rolling mills are the similar to 4-high rolling mills however, they have work rolls, intermediate rolls, and back up rolls. Refer to Drawings (right), which shows a 6-high reversing mill for rolling light gauge steel. The intermediate rolls can be adjusted horizontally to prevent edge drop, which means the edge become lighter in thickness
By increasing the carbon content, steel can be made hot at temperatures above 1200oF. Normally, high carbon steel is further heat treated, such as quenched and tempered, to increase the yield and tensile strengths. Because of the high carbon content, when you quench steel in water, as an example, the steel becomes very hard, (i.e.
