高压变频调速技术在转炉除尘风机上的研究与应用

Application Research of High Voltage Changing Frequency Regulation Speed Technique in Dedusting Exhaust Blower of Converter

莱钢炼钢厂将高压变频调速技术应用于1#转炉除尘风机,经合理设计方案,实现了除尘风机随转炉冶炼周期自动合理调速,减少了设备故障。该系统安全可靠,操作简单,节电率达60%,年节电效益达8316万元。

High voltage changing frequency regula t ion speed technique has been applied to dedusting exhaust blower of No.1 convert er in the steelmaking plant of Laiwu iron and steel group Co.,Ltd.Through reason able plan design,the automatical and reasonable regulation speed of dedusting exhaust blower with meeting cycle of converter can be implemented and the equipment fai lure ratio can be decreased.This system is safe and convenient,it's power saving ratio is up to 60% and profit of power saving is up to 08316 million yuan e very year.
