摘要
本设计要求建年产量为160万吨炼钢生铁的高炉车间。
在设计中采用了2048 m3的高炉1座,不设渣口,2个出铁口,采用矩形出铁场。送风系统采用四座新日铁式外燃式热风炉,煤气处理系统采用重力除尘,文氏管和电除尘。渣铁处理系统采用轮法粒化渣处理工艺处理,特殊情况采用干渣生产,上料系统采用皮带上料机,保证高炉的不间断供料。
在设计中,首先作了物料平衡.热平衡.炉形的设计与计算,以及设备的选择;设计中应用了选多先进的工艺,这些工艺在实行大喷煤技术提高传热效率,节能,提高生产率方面起了重要作用。在设计中,广泛吸收前任技术革新和国内外科学研究成果。根据实际需要及可能性,尽量采用先进设备.结构.材料及新工艺。做到技术上先进,经济上合理,有减少环境污染。
Abstract
The assignment in the design of the 1.6 million tons annual production capacity of steel-making cast ieon in blast furnace Workshop
used in the design of the one 2048 m3 blast furnace ,no set up Jardine ,two taphole , the use of rectangular field of iron. Blast system 4 Nippon external combustion hot stove, Dust catcher system using gravity precipitators , vebturi tube and electrostatic precipitator .Tapping system method of Wheel law granular slag to deal with special
circumstances dry slag production ,the charging system is used in feed belt to ensure uninterrupted blast furnace charge .
In the design, first of all made a material balance, heat balane ,and calculation of furnace design ,as well as the chice of equipment ;the design of the application of a number of advanced technology ,these processes in implementation of large pulverized coal injection technology ,these processes in the implementation of large pulverized coal injection technology to enhance heat transfer efficiency ,energy saving ,to improve productivity played an important role .in the design, the broad absorption of previous technological innovations an the results of scientific research at home an abroad . According to the actual needs and possibilities , as far as possible the use of advanced equipment, advanced structure, advanced materials and so on .Achieve technicaiiy
