赵紫平：年产300万吨生铁高炉设计江西理工大学应用科学学院毕业设计PAGE 40PAGE 39 年产300万吨生铁高炉设计摘要高炉炼铁是传统的炼铁工艺，也是钢铁冶金过程中最重要的环节之一，在国民经济建设中起着举足轻重的作用。随着钢铁行业的蓬勃发展和节能环保要求的日益严格，高炉炉型逐渐走向大型化。本论文对年产300万吨生铁大型高炉车间进行了设计，设计内容包括炼铁物料平衡和热平衡计算、高炉炉型确定、高炉各部位炉衬、炉体冷却设备的选择和风口的设计。此外，还就高炉附属系统的煤气除尘处理系统进行了设计。本设计的高炉车间共有容积2162m3的大型高炉两座，高炉车间按并列式布置。关键词：高炉；炼铁工艺计算；设计；煤气处理 Abstract Blast furnace ironmaking was the traditional iron-making craft, also was one of the most important link in ferrous metallurgy, it played a decisive role in national economic construction. With the vigorous development of the steel industry and more and more strict requirement of energy conservation and environmental protection requirement, the BF became maximization gradually.A large scale BF plant which had annual output of 3 million tons of pig iron was designed in this thesis, design content includeed material balance and thermal equilibrium calculation, determination of BF profile, selection of lining and cooling equipment for each part of BF and design of taphole. In addition, the gas processing sytem which was one of the BF subsidiary system was designed.The ironmaking plant of this thesis has two 2162m3 BF, they were layouted side by side.Key words:blast furnace；Ironmaking process calculation；design；gas processing 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc293943356 2011年 4 月17日 PAGEREF _Toc293943356 \h 1 HYPERLINK \l _Toc293943357 摘要 PAGEREF _Toc293943357 \h I HYPERLINK \l _Toc293943358 Abstract PAGEREF _Toc293943358 \h II HYPERLINK \l _Toc293943359 目 录 PAGEREF _Toc293943359 \h III HYPERLINK \l _Toc293943360 第一章 绪论 PAGEREF _Toc293943360 \h 1 HYPERLINK \l _Toc293943361 1.1高炉炼铁概述 PAGEREF _Toc293943361 \h 1 HYPERLINK \l _Toc293943362 1.2高炉生产主要经济技术指标 PAGEREF _Toc293943362 \h 2 HYPERLINK \l _Toc293943363 1.3高炉炉型发展趋势 PAGEREF _Toc293943363 \h 3 HYPERLINK \l _Toc293943364 1.4高炉炼铁设计应遵循的原则 PAGEREF _Toc293943364 \h 3 HYPERLINK \l _Toc293943365 第二章 高炉配料计算 PAGEREF _Toc293943365 \h 5 HYPERLINK \l _Toc293943366 2
