| Abstract: | This is a further research about gas recovery system of converter steelmaking in a steelmaking plant.And the gas recovery system is designed based on Siemens S7-300 automatic control system.The recycling process of gas recovery construct with S7-300 as the main station,transferring data by Profibus,monitoring by Siemens WinCC system.And on the basis of the above,data are transferred between S7-300 and Profibus-DP by S7-300 as the main station,and the frequency of the winds of pressure machine are changed with transducer,in the end the gas are supplied continually by controlling gas reflux. |
