摘　要:年產60萬噸電爐煉鋼車間設計以廢鋼為原料，通過冶金計算并在理論論證的基礎上，采用90t超高功率電弧爐冶煉，之后依次使用LF爐和VD爐進行精煉，最后使用連鑄機獲得鋼坯。主要生產Q255合金鋼管，并在設計過程中融入了廢鋼預熱、偏心爐底出鋼、水冷掛渣爐壁等目前較為流行的生產技術。在導師的指引下，設計過程中綜合運用大學所學知識，分析解決實際問題，自我受益匪淺。

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.

電弧爐車間的爐渣運輸方式有爐前吊渣罐和操作平臺下拖運渣車兩種方式。拖運灣車方式為當代高架式電弧爐普遍采用，爐渣滿灌后運到爐渣跨處理．空渣罐再返回爐前待用。這種布置方式不影響其他工序，且改善環境。缺點是增大占地面積和投資。現代電弧爐車間采用泡沫渣操作，冶煉周期在60min以內，渣量大，在設計時應增加渣罐容積，對爐渣的處理也應采用潑渣法。
