摘要
武钢4号高炉不放上渣操作是从1987年11月开始的,在国内有渣口的高炉尚属首创。文中论述了不放上渣操作的条件(两个铁口、渣量500 kg/t_铁、日出铁15次)和经济效益(节焦13 kg/t_铁、增产38 t/d、一年节约渣口小套经济价值118608元)。不放上渣的高炉能降低铁水的硅和硫含量,提高生铁质量,其操作可在国内所有两个铁口的高炉上推广。
Since november 1987 the cinder notches have been closed on No.4 blast furnace at WuhanIron and Steel Corp..It is the first in this kind of blast furnaces with cinder notches closed inChina.The conditions of this B.F.operation are as follows:2 iron notches,slag volume 500kg/THM,15 casts per day.The advantages of the new practice are decrease in coke rate by 13kg/THM,increase in hot metal output by 38t/day,and ￥118,608 RMB per year saved for jackets ofcinder notches.This practice may be spread to all blast furnaces with two iron notches throughout China.
