| In the metallurgical enterprise,blast furnace feeding system is a very important complicated equipment system, in order to ensure the steady, safe and efficient to the work, the design and realization of the material to high computer automation control is very important. In enhancing the control control precision of the system, and on the basis of the blast furnace to further improve the material to the reliability and safety of operation, stability, and to ask of the blast furnace provides the reliable safeguard for production. Based on the actual scientific research project, the feeding system of blast furnace automation reconstruction, development and design a set of blast furnace production line for automatic control system.Subject tracking domestic and international advanced technology, used in today’s advanced no bells furnace item of equipment, increase equipment reliability and reduce consumption of spare parts, the cost savings. In the comprehensive control of the production process at home and abroad on the basis of the development of technology, the development of design of PLC control system. In this system, the PLC as a core part, and the whole production line to play a monitoring and control function, to all kinds of electromagnetic valve mechanical parts a control instruction, and combined with the configuration software can complete paper requirement. According to the input and output point to the PLC hardware configuration; According to the characteristics of PLC programming, using the method for preparation of the circuit to factory-ladder diagram for software establishment, and the software is divided into several parts, according to the actual need to design the corresponding modules, realize the specific function; making the configuration software to realize interface, data display, equipment state, cloth, historical trends and set print management, the user can carry out all the data change operation.In the original conventional control system on the basis of optimized. The material flow valve is controled by PID control to adjust. Through the precise structure model of blast furnace cloth system for a detailed analysis and effective to solve the material flow valve relative error and the regulation of the larger rapid, blast furnace for the high and stable yields created the conditions. |
