Design and Application of Computer Control System of Blending and Feeding for Blast Furnace

This paper mainly introduced the process control system of blending and feeding for blast furnace based on Siemens S7 series PLC and industry PC. Configuration software WinCC6.0 and Visual Basic6.0 were used to monitor and manage process data. Development environment for basic automation system that used to realize logical interlocks and pulse measurement is Siemens Step 7 V5.2. The way how to choose and exchange hopper automatically and automatic precise blending could meet the desire of process control system.
