65万吨电炉炼钢车间设计毕业论文设计.doc

65万吨电炉炼钢车间设计 材料与冶金学院 指导老师： 摘 要 电炉短流程钢厂与转炉长流程钢厂相比，在占地、投资、节能、环保等方面都有优势，电炉钢比逐年提高是冶金工业发展趋势。中国钢铁业存在的问题有设备老化、普通钢生产过剩、生产率低，而优质钢产品质量欠佳、生产能力薄弱等；再加上中国废钢资源不足，电炉钢比一直处于较低水平，相比西方主要产钢国存在一定差距。随着电弧炉采用高功率或超高功率，炉外精炼、连续铸钢，连续轧钢等一系列技术的发展和社会废钢资源的足量累计，直接还原技术的开发，二次精炼技术的飞速发展，电力工业的发展，电弧炉生产成本会相对下降，国家对能源、资源和环保标准的进一步提高及管理的加强，电炉炼钢有着更加广阔的发展空间，电炉钢在钢产量上的比例增长势头不会改变。通过查阅国内外电炉车间设计的文献资料，阅读有关书籍，并向老师请教完成了本次设计。包括产品大纲的制定；电炉、炉外精炼、连铸的论证；然后进行配料计算，选择合适设备；最后绘出电炉的剖面图和电炉车间的平面布置图。 关键字：电弧炉；车间设计；超高功率；连铸；炉外精炼 ABSTRACT Compared with the long steel mill, the short process steel plant of the electric furnace has advantages in the area of the area, investment, energy saving and environmental protection. The electric furnace steel is the development trend of the metallurgical industry..?Problems existed in the Chinese iron and steel industry of aging equipment, ordinary steel overproduction, low productivity, and poor quality of the high quality steel products, production capacity is weak, coupled with the lack of scrap resources in China, the electric furnace steel than has been in a low level, compared to the western major steel producing countries, there is a certain gap.With the electric arc furnace with high power and ultra high power, refining, continuous casting, continuous rolling and a series of technical development and social scrap resources adequate amounts of accumulated development of direct reduction technology, rapid development of secondary refining technology, the development of electric power industry, electric arc furnace production cost will decline relative, countries on energy, resources and environmental standards to further improve the management and strengthen, EAF steel making has a broader space for development, electric furnace steel in steel output in the proportion of growth momentum will not change.Through the review of domestic and foreign electric furnace workshop design literature, read about books, and to the teacher to consult the completion of the design.?Including the formu
