Designing Drive Control System for C Table Roller in Hot Rolling Mill |
| |
| Abstract: | The general introduction of existing DC driving system of C table roller in hot rolling mill is given and the problems in such system are analyzed. The features of table roller driving system and the requirements for speed adjustment control system are discussed. The U/f AC variable frequency driving system and PLC control system are designed in accordance with the demands of retrofit project, and the PLC program flowchart is also given. Comparing with the past DC drive system, the new design improves the operational performance greatly. The requirement of enhancing overall technical level of hot rolling plant can be satisfied. |
