Research and application of computer control system for aluminium single-stand 4-high cold rolling mill
This study introduces the technical specifications and the technological process of the aluminium single-stand 4-high cold rolling mill, and analyses the mathematical model of the rolling process. The automation system adopts 3-level computer control, which actuators and sensors (Level 0), basic automation level (Level 1) and process automation level (Level 2), to realise the network data tracking, dynamic adaptive rolling procedure setting, self-learning model and automatic control of the whole rolling process. The computer control system described has been in full commercial operation after a large number of functional and performance tests. The effectiveness of 3-level control concept was verified to ensure the quality of the product, and to meet the expected goal of designing.
