With increasing yield points, the forces that occur during the leveling process and the thereby necessary driving torque also increase. An appropriately sized leveler machine is therefore a prerequisite for processing high-tensile sheets in order to meet the demanding requirements for evenness and surface quality.

Among others, for the usage in high strength steels SCHNUTZ has developed the multi-motor drive. Here, the guide rollers are driven not by one, but in groups of several motors. This technology has a number of important advantages:

• Gentle handling of sensitive strip surfaces by reducing friction between the strip and the leveling rolls

• Increased life expectancy of leveling rolls due to the reduced friction

• Less power consumption due to the considerably lower friction and tension in the transfer box

• Monitoring of the actual driving torque for the leveling roll groups

• Redundancy in the case of the failure of a drive
