Transformation and Optimization of Tilting Control System of 110t Converter
The automatic control system of 110 tons of stainless steel converter adopts Siemens S7-300PLC for logic control such as start,stop and fault,and two sets of AC Siemens frequency converter complete closed-loop dynamic adjustment of the motor,and two motors adopt mas-ter-slave control mode to ensure load balance.Profibus-DP communication is adopted between two frequency converters and PLC.It mainly fo-cuses on the problems existing in the operation of the converter tilting system,and focuses on the upgrading and optimization of the tilting fre-quency conversion control system.Based on the new generation of Siemens inverter S120 as the core,the converter tilting control system is up-graded,and the problems such as mutual dragging,unreliable locking control mode and converter nodding are solved by establishing a new control mode in the operation of dual-drive tilting system.Improve the control accuracy to achieve the purpose of enhancing the safe and stable operation of equipment.The practice shows that the modified and optimized tilting control system can meet the requirements of safety,stabili-ty,reliability,efficiency and accuracy of the converter smelting process.
