摘　　要：为提高加热炉汽化冷却系统控制水平及精度,济钢采用变频器、智能调节器、差压变送器对其进行了改造,建立了汽包水位的闭环串级自动控制系统,当水位变化时,智能调节器可根据差压变送器的输出参数,自动调节变频器的输出转速,从而实现了汽包水位的自动控制调节,汽包水位波动范围可达到±5mm,节电率达70%。In order to advance the automation level of evaporated cooling system of heating furnace and the control precision, Jinan Steel adopted transducer, intelligent adjuster and differential pressure transmitter to transform it, and established a closed-loop cascade control system of the drum water level. When the water level changed, the intelligent adjuster automatically regulated the output speed of the transducer according to the output parameters of the differential pressure transmitter, then realizing the automation adjustment of the drum water level. The fluctuated range of the drum water level could be controlled within ± 5 mm. The power saving rate of the system reached to 70%.
