The Application of Pressurized Blast Hole Water-Saving Device of 3BF in Anyang Steel
Hou Hua-min · Gansu Metallurgy · 2008
This paper analyses the cause of inadequate intensity of cooling of the furnace shaft of 3BF of Anyang'Steel.Further more,it concludes the rebuiding experience of the furnace shaft cooling system.By installing the pressurized blast hole water-saving device,the cooling intensity at the furnace belly and bosh is increased,which meets the need of high-intensity of blast furnace smelting.Therefore,cooling water is saved by increaced pressure,and the life of the furnace shaft is lenghened.
