产400万吨合格铸坯转炉炼钢系统设计——转炉系统主体设计本科毕业设计说明书.doc

内蒙古科技大学 本科生毕业设计说明书 题 目：年产400万吨合格铸坯转炉 炼钢工程——转炉系统主体设计 专 业：冶金工程 摘要 然后进行车间计算和所用设备的规格和数量的设计，在此基础上进行车间尺寸计算，确定各层平台标高。最后对转炉车间设计环境和安全要求进行说明关键词：炼钢炉型设计ABSTRACT To meet the needs of the market, this design is: an annual output of 400 million tons of qualified billet converter steelmaking project - the main design of the converter system.The design in the case of the production of other qualified slab weathering steel as the main production of high value-added steel.From the blast furnace hot metal into steel plant began smelting process as follows:Hot Metal Pretreatment Torpedo cars Converter end of blowing argon LF Refining Slab Continuous Casting The hot-rolled unit of the in broadband Rough rolling Finishing Controlled cooling Take-up Sampling and testing Package Treasury,Through this process to produce qualified weathering steel plate blanks.This design uses two 200-ton converter,and furnace size, the metal structure, tilting mechanism, the calculation of the converter oxygen supply system, bulk system, flue gas purification system,hot metal pretreatment system, refining the system, casting a brief design and discussion.Determined after the layout of the workshop, workshop calculation and specifications of the equipment used and the number of design, on this basis, the workshop size calculation to determine the elevation of each floor platform. Finally, the environmental and safety requirements of the converter plant design description. More image described the converter steelmaking process and related equipment, structures in the design, add a large number of graphics Keyword:Steel-making furnace design, weathering steel, hot metal supply, the smelting process 目录 摘要 I ABSTRACT II 第一章 文献综述 1 1.1转炉的发展历程 1 1.2 我国转炉炼钢现状 1 1.2.1 转炉钢产量 1 1.2.2 转炉炼钢原材料 3 1.3 我国转炉炼钢发展现状 5 1.3.1 发展条件和机遇 5 1.3.2 转炉炼钢的发展与钢产量的增长方式 7 1.4 转炉自动化技术 7 1.4.1 介绍 7 1.4.2 技术分类 8 1.5 转炉炼
