毕业论文--65万吨电炉炼钢车间设计.doc

辽宁科技大学本科生毕业论文 65 万吨电炉炼钢车间设计材料与冶金学院指导老师: 辽宁科技大学本科生毕业论文 II 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;炉外精炼辽宁科技大学本科生毕业论文 III pared with the long steel mill, the short process steel plant ofthe electric furnace has advantages inthe area ofthe area, investment, energy saving and environmental protection. The electric furnace steel isthe development trend ofthe metallurgical industry.. Problems existed inthe Chinese iron and steel industry ofaging equipment, ordinary steel overproduction, low productivity, and poor quality ofthe high quality steel products, production capacity isweak, coupled with the lack ofscrap resources inChina, the electric furnace steel than has been inalow level, compared tothe western major steel producing countries, there isacertain the electric arc furnace with high power and ultra high power, refining, continuous casting, continuous rolling and a series oftechnical development and social scrap resources adequate amounts of accumulated development ofdirect reduction technology, rapid development of secondary refining technology, the development ofelectric power industry, electric arc furnace production cost will decline relative, countries onenergy, resources and environmental standards tofurther improve the management and strengthen, EAF steel making has abroader space for development, electric furnace steel insteel output inthe proportion ofgrowth momentum will not the review ofdomestic and foreign electric furnace workshop design literature, read about books, and tothe teacher toconsult pletion ofthe design. Including the formulation ofprod
