高炉冷却系统结垢的清洗问题,国内外很久以来没有得到解决。鞍钢炼铁厂曾采用苏联的酸洗办法,效果极低,一般使用2～3年后水管就结上3～8毫米厚的水垢,使冷却效果大为降低,尤其是高炉强化后,就更不能适应生产的要求。近来高炉炉缸采用炭素材料后寿命可大为延长,要求水冷系统也能延长使用寿命,否则就会因水冷系统结垢严重而被迫停炉。因此,近年来我厂职工都在积极摸索一种新的清除水垢的方法,如:利用高压水,高压蒸汽,压缩空气的冲洗和采用不同配比的酸洗等,所有这些方法虽起到一些效果,但终究没有解决水管继续结垢的问题。最近配管工段老配管工李国忠同志等,经过118次的
Blast furnace cooling system scaling cleaning problems, at home and abroad for a long time have not been resolved. Ansteel Iron Works had used the Soviet Union pickling method, the effect is very low, the general use of 2 to 3 years after the water pipes on the 3 to 8 mm thick scale, greatly reducing the cooling effect, especially after the blast furnace to strengthen Can not meet the production requirements. Recently, the use of carbonaceous materials blast furnace hearth life can be greatly extended, requiring water cooling system can also extend the service life, otherwise it will be due to severe water cooling system was forced to shutdown furnace. Therefore, in recent years, I plant workers are actively exploring a new method of scavenging, such as: the use of high-pressure water, high pressure steam, compressed air washing and the use of different proportions of pickling, all of these methods to play some Effect, but after all, did not solve the problem of water pipes to continue scaling.
