针对高炉不同的出铁工况，设计出一种高炉出铁场除尘恒风压变频调速模型，以满足高炉出铁过程中的正常风量需要，保持恒定的除尘总管风压；通过出铁场除尘阀门控制技术，将除尘控制设置在炉前泥炮操作室，完成对除尘阀门和风机的操作。梅钢5#高炉（4070 m3，风机装机量2×2240 kW）应用表明，出铁场除尘风机吨铁总电耗为5.78 kW·h，节能减排效果明显。
針對高爐不同的齣鐵工況，設計齣一種高爐齣鐵場除塵恆風壓變頻調速模型，以滿足高爐齣鐵過程中的正常風量需要，保持恆定的除塵總管風壓；通過齣鐵場除塵閥門控製技術，將除塵控製設置在爐前泥砲操作室，完成對除塵閥門和風機的操作。梅鋼5#高爐（4070 m3，風機裝機量2×2240 kW）應用錶明，齣鐵場除塵風機噸鐵總電耗為5.78 kW·h，節能減排效果明顯。

According to different conditions of blast furnace casthouse, the article designs a frequency control model of speed regulation which can keep dedust pressure constant for blast furnace casthouse dust, can meet the needs of normal flue gas volume in the process of blast furnace production, can keep the pressure constant of gas piping stress. By means of the field dedusting valve control technology, due to it is set in the dust control mud gun in front of the furnace operation room, it can finish the operation of the dedusting valve and fan. The application in Meigang’s No.5 blast furnace fan installed with 2×2 (4 070 m3, 240 kW) shows that the field of iron dust removal fan ton iron total power consumption is 5.78 kW·h, energy conservation and emissions reduction effect is obviously.
