Fully Automatic Control System for the Drum Water Level for Converter

This paper describes the application of the fully automatic detection and control system for steam drum water level of the waste heat boiler for the 150t Converter of Baotou Iron and Steel Corporation:the drum water level is measured by means of capacitance intelligent drum water level meter working under all the conditions;the pressure in the water feed main pipe to steam drum is controlled by variable frequency water supply pump;the drum water level is controlled by feed water regulating valve;the fully automatic control of drum water level in various smelting stages is realized through software programming,so as to finally realize the accurate control of drum water level.
