摘 要:年产60万吨电炉炼钢车间设计以废钢为原料，通过冶金计算并在理论论证的基础上，采用90t超高功率电弧炉冶炼，之后依次使用LF炉和VD炉进行精炼，最后使用连铸机获得钢坯。主要生产Q255合金钢管，并在设计过程中融入了废钢预热、偏心炉底出钢、水冷挂渣炉壁等目前较为流行的生产技术。在导师的指引下，设计过程中综合运用大学所学知识，分析解决实际问题，自我受益匪浅。

ABSTRACT:Annual 60 tons of eaf adn workshop designed to scrap steel as raw material, through calculation and theoretical arguments of metallurgy, on the basis of high power electric arc furnace by 90t LF after use, in smelting furnace refining, finally get billet caster in use. The main production Q255 alloy steel tube, and in the design process into scrap steel preheating, eccentric furnace bottom, water-cooled hang the steel slag furnace wall, are relatively popular production technology. In mentor, under the guidance of the design process comprehensive use of university studied the knowledge, analyze and solve practical problems, self benefit.

电弧炉车间的炉渣运输方式有炉前吊渣罐和操作平台下拖运渣车两种方式。拖运湾车方式为当代高架式电弧炉普遍采用，炉渣满灌后运到炉渣跨处理．空渣罐再返回炉前待用。这种布置方式不影响其他工序，且改善环境。缺点是增大占地面积和投资。现代电弧炉车间采用泡沫渣操作，冶炼周期在60min以内，渣量大，在设计时应增加渣罐容积，对炉渣的处理也应采用泼渣法。
