The Q-Tube - Process Control System (PCS) module is designed to achieve quality, consistency and process repeatability featuring the following main functions:
Technological Data Management allows easy and safe management of the technological information required to configure and adjust process treatments. Process Setup Management is designed to support the process engineer and operators with the following activities: - Rolling schedule calculation. - Offline plant setup calculation through Danieli’s mathematical model. - On-line tuning of preset data with adaptive mathematical model for FQM and SRM.
Roll Set Management is designed to support the activities of workshop foreman and operators. Hydraulic Gap Control (HGC) is a closed-loop regulating function, providing fast and accurate positioning of the rolls of the FQM. Speed Control System (SCS) generates the proper speed references, equipment positioning and sequence control for the FQM and the SRM/SM areas. Heavy End Control (HEC) minimizes the heavy ends created at the head and tail of the tube, and leads to a higher output of the SRM. Automatic Wall Thickness Control (AWTC) controls the wall thickness of the outcoming tube during rolling, adjusting the applied tension to the tube in the SRM.
