炼钢转炉汽包水位全自动控制系统

Fully Automatic Control System for the Drum Water Level for Converter

介绍包钢150t转炉余热锅炉汽包水位全自动检测控制系统的应用:采用全工况电容式智能汽包水位计测量汽包水位,采用变频给水泵控制汽包给水母管的压力,采用给水调节阀控制汽包水位,通过软件编程实现汽包水位在转炉冶炼不同阶段的全自动控制方式,最终实现汽包水位的准确控制。

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 Coloration： the drum water level is meastued 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 fidly 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.
