包头原料条件下2200立方米高炉炉体及喷吹系统设计说明书.doc

本科生毕业设计说明书 题 目：包头原料条件下2200m3高炉炉体及喷吹系统设计 包头原料条件下00m3高炉本体及渣铁处理系统设计 摘要 高炉喷煤是20世纪60年代开始大规模应用于钢铁工业生产的炼铁新技术。随着石油危机、环保和炼焦煤资源日益短缺等问题，高炉喷煤不仅是高炉调剂的一项重要手段，同时还是弥补焦炭不足的主要措施。而且高炉喷煤是降低炼铁生产成本的有效途径。本设计结合包钢地区原料条件下和对目前国内外先进高炉喷吹工艺的学习。采用并罐直接喷吹形式的喷煤方式设计的2200m3高炉喷煤系统。系统设计包括高炉喷煤储运系统设计、高炉喷煤制粉系统设计、高炉喷煤喷吹系统设计、高炉喷煤安全设计。从而以价格低廉的煤粉部分替代价格昂贵而日趋贬值的冶金焦炭，使高炉炼铁焦比降低，生铁成分下降。增加效益。  关键词：高炉；The Design of 2200 m3 Blast Furnace Slag Ontology and Iron Processing System Under the Raw Material Conditions in Baotou Region Abstract The blast furnace coal is the 1960 s large scale application steel industry production of new iron-making technique. As the oil crisis, environmental protection and coking coal resources increasingly scarce, blast furnace has not only the blast furnace is coal adjusted a and also an important way to make up for the lack of coke or major measures. And blast furnace ironmaking is to reduce production cost coal the effective way. This design with Baotou area of material condition and at home and abroad and advanced injection process of blast furnace study. The adoption and cans of direct injection from of pulverized coal injection way of 2200 m3design of blast furnace coal system. System of blast furnace design including coal storage system design,blast furnace coal pulverizing system design, blast furnace pulverized coal injection system design, blast furnace safety design of coal. And the low price of coal powder partly replace expensive and more lack of metallurgical coke, make the blast furnace ironmaking coke rate reduce, pig iron cost down. Increase benefits. Key words：coal of blast furnace， blast furnace，injection technology 目 录 摘要 II Abstract I 第一章 文献综述 1 1.1高炉发展史 1 1.2五段式高炉炉型 3 1.2.1 高炉有效容积Vu和有效高度Hu 3 1.2.2 Hu/D 3 1.2.3 h0、h1、h2、h3、h4和h5 4 1.2.4 α、β角 4 5 1.3.1原煤储运系统 5 1.3.2制粉系统 5 1.3.3煤粉的输送 6 1.3.4喷吹系统 6 1.3.5供气系统 6 1.3.6煤粉计量 7 1.3.7 控制系统 7 1.4高炉烟煤喷 10 1.4.1 高炉混喷烟煤的优越性 10 1.4.2 国外高炉混喷烟煤工艺的发展现状 11 1.4.3 国内喷吹烟煤工艺的发展现状 12 第二章炼铁工艺计算 14 2.1 高炉物料平衡计算 14 2.1.1 原料条件及平衡计算 14 2
