1 引言 柳钢2号高炉有效容积为308m~3,1996年前高炉使用风温一直徘徊在960℃左右,各项技术指标与全国地方骨干企业有较大的差距。随着市场竞争的激烈,能否摆脱当前低产高能耗的不利局面,走高风温低能耗之路是当务之急。2号高炉利用1996年初中修机会对3座热风炉进行改造:改用繁体五孔格子砖,采用新型陶瓷燃烧器,冷风均匀配气装置,利用热风炉烟气余热对热风炉助燃空气
1 Introduction Liuzhou Iron and Steel Co., Ltd. 2 blast furnace effective volume of 308m ~ 3, before 1996 blast furnace temperature has been hovering around 960 ℃, the technical indicators and the local backbone enterprises have a greater gap. With fierce competition in the market, it is imperative to be able to get out of the current unfavorable situation of low output and high energy consumption. No. 2 blast furnace used in early 1996 opportunities to repair three hot stoves: switch to the traditional five-hole lattice brick, the use of new ceramic burners, uniform distribution of cold air device, the use of hot stove flue gas waste heat on the hot air stove combustion air
