Abstract
Methods to drive material conditioning machines are described. An example method includes determining a first torque of a first roller of a material conditioning machine through which the strip material moves, calculating a second torque of a second roller of the material conditioning machine based on a relationship between the second torque and the first torque, and maintaining the relationship between the second torque and the first torque by adjusting the second torque after a change in the first torque.

A method of leveling a strip material, the method comprising:
- determining a first torque of a first roller of a material conditioning machine through which the strip material moves;
- calculating a second torque of a second roller of the material conditioning machine based on a predetermined ratio between the second torque and the first torque, wherein the first roller is located at an entry of the material conditioning machine and the second roller is located at an exit of the material conditioning machine, the second roller located downstream from the first roller;
- and
- maintaining the ratio between the second torque and the first torque by adjusting the second torque in response to a change in the first torque to level the strip material.

A method of leveling a strip material, the method comprising:
- monitoring a first torque applied to a first plurality of work rolls of a first drive system of a material conditioning machine, wherein the strip material moves through the material conditioning machine;
- communicating the first torque to a second drive system of the material conditioning machine, the second drive system comprising a second plurality of work rolls;
- calculating a second torque to be applied to the second plurality of work rolls based on a predetermined ratio between the second torque and the first torque;
- varying the second torque applied to the second plurality of work rolls to maintain the ratio between the first torque and the second torque by varying a plunge depth of the second plurality of work rolls;
- and
- leveling the strip material based on the first torque, the second torque, and the plunge depth.
