Pass to pass adaptation corrects the prediction for the actual piece based on the measurements on the rolled passes. Piece to piece adaptation corrects the adaptive coefficients for the rolled product based on the measurements collected for each piece of the same type. The mill setup strategy is designed to split up the rolling process into two phases called roughing and finishing. The goal of the finishing phase is to obtain a load distribution for good shape of the final product while the aim of the roughing phase draft calculation is to reach the intermediate bar thickness optimising the torque and loading. Production began in 1997, and over the last three years production capability has increased in terms of material quantity and minimum thickness.
Dimensional quality is controlled by the technological functions provided in the automation system.
Maintenance of the system is ongoing.
