马钢二铁厂有4座294m~3高炉。为了提高高炉冷却强度,延长冷却壁使用寿命,采用了化学清洗药剂对冷却壁水管进清洗。清洗工艺如下:在现有分水器旋塞上,再装一个三通旋塞,分别接上药液管和水管,开泵后关闭进水旋塞,接通药液,使药液在冷却壁水管中循环,经20～40min后打开进水旋塞,关闭药液旋塞,即完成了1～2块冷却壁(箱)清洗工作。如此逐一清洗其它冷却器。由于药液中加入缓蚀剂,对水管腐蚀作用很轻
There are 4 294m ~ 3 blast furnaces at Masteel II Iron Works. In order to improve the cooling strength of the blast furnace to extend the life of the cooling wall, the use of chemical cleaning agent on the cooling water pipe cleaning. Cleaning process is as follows: In the existing manifold tap, and then install a three-way cock, respectively, connected to the liquid pipe and water pipe, turn off the water inlet after the pump cock, connect the liquid, so liquid in the cooling water pipe Cycle, after 20 ~ 40min open the water cock, close the cocks, which completed 1 or 2 cooling wall (box) cleaning. So wash the other cooler one by one. Corrosion due to the corrosion inhibitor added to the liquid pipe is very light
