Automatic Gauge Control

The main target of the AGC control is to maintain a good thickness tolerance over the entire range of products in varying process conditions viz. different materials, different alloys, different material dimensions meaning different material stiffness. A system is offered with an adaptive algorithm, different control strategies are available depending on the mill to realize the desired thickness tolerances. All functions necessary for the regulation, control and sequencing of mill actuators to realize the AGC function are provided. The immediate result of the AGC system is that the flat products rolled in the mill are of required thickness and within the required tolerance.
