年产量280万吨炼钢生铁40万吨铸造生铁的炼铁车间
摘要
本设计是设计年产280万吨炼钢生铁,40万吨铸造生铁的高炉炼铁车间。
在设计中采用了2022m3的高炉2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器、文氏管和电除尘。渣铁处理系统采用拉萨法水淬渣(RASA)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,首先做了物料平衡、热平衡,炉型的设计与计算,以及设备的选择;设计中应用了许多先进的工艺,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的作用。在设计中,广泛吸收前人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,又减少环境污染。
车间总体布置形式为半岛式。
关键词:高炉,物料平衡,热平衡,半岛式
Design of an ironmaking workshop with annual output of million tons of steelmaking iron and million tons of Casting iron
Abstract
The assignment is the design of the million tons annual production capacity of steel-making pig iron, of blast furnace cast pig iron workshop. I design two 1800 m3 blast furnaces,and set up two tap holes with no slag hole,which use rectangular field of iron. Blast system 4 Nippon bustion hot stoves,Dust catcher system uses gravity precipitators, venturi tube and electrostatic precipitator. The methods of slag iron processing system use water quenching residue Lhasa (RASA), special circumstances use dry slag productions to deal with. The charging system is using belt feeding machine to ensuring uninterrupting charging of blast furnace. In the design,first of all, calculating the material balance, heat balance, and the furnace structure, as well as the choice of equipment; the design of the application of a number of advanced technology, these processes in the implementation of large pulverized coal injection technology to enhance heat transfer efficiency,to save energy ,to improve productivity ,which played an important role. The design has broadly absorpted technological innovations and the results of scientific research at home and abroad. According to the actual needs and possibilities use advanced equipment as far as possible,advanced structure,advanced materials and so on. Achieve technically advanced and economically rational,and reduce
