Roll steering control systems and methods for tandem mills

A rolling mill comprising a steering control system, the steering control system comprising:

• a steering control actuator adapted to control an inclination of a work roll of a work stand of the rolling mill;
• a sensor configured to measure a parameter of a metal substrate upstream from the work stand;
• and
• a controller operably connected with the steering control actuator and the sensor, wherein the controller comprises a processor and a memory coupled to the processor, wherein the memory comprises instructions executable by the processor for:
• generating a model for the work stand and determining an adjustment value for the work stand;
• receiving the measured parameter from the sensor;
• determining an expected output parameter by adjusting the measured parameter by the adjustment value;
• comparing the expected output parameter with a target output parameter, and
• actuating the steering control actuator such that the expected output parameter is within a predefined tolerance of the target parameter.

A steering control system for a rolling mill, the steering control system comprising:

• at least one processor;
• a memory coupled to the processor, wherein the memory comprises a plurality of instructions executable by the processor for:
• generating a model for a work stand and determining an adjustment value for the work stand;
• receiving a measured parameter about a metal substrate from a sensor upstream from the work stand;
• determining an expected output parameter by adjusting the measured parameter by the adjustment value;
• comparing the expected output parameter with a target output parameter;
• and
• generating a control response based on the expected output parameter being outside of a predefined tolerance of the target parameter.
