transformers and major electrical parameters of the calculation。 關鍵詞 :電爐 鋼坯 設計 畢業(yè)論文(設計) 第 V 頁 Yearly produces 1,000,000 tons billets (spindle) the ectric steelmaking workshop preliminary design Abstract World EAF steel production is growing, the total crude steel production output of 1 / 3, but is currently facing our country since 1990, an annual decline in the second situation. Therefore, in view of the current shortage of scrap steel and electricity status quo, from a global sustainable development and to make our country into a great power by the Iron and Steel Iron and Steel strategic power, the current macrocontrol by the State to support the development of China39。 本設計根據(jù)這些情況并結合貴州地區(qū)的市場需求 、 廢鋼資源、生鐵資源、電力資源、水資源、 交通運輸、環(huán)境保護等多方面提出在貴州地區(qū)興建年產(chǎn) 100 萬噸鋼坯(錠)電爐煉鋼車間的可能性并作了可行性分析,在此基礎上進行了電爐車間的初步設計。 畢業(yè)論文(設計) 第 I 頁 年產(chǎn) 100萬噸鋼坯 (錠 )電爐煉鋼車間初步設計 畢業(yè)論文(設計) 第 II 頁 目 錄 摘 要 .................................................................................................................

The design under these circumstances and with the Guizhou region metallurgical resources, market demand, transportation, environmental protection, and so propose the construction of the Guizhou region with an annual output of 1,000,000 tons steel billet (ingot) electric furnace steelmaking workshop and the possibility of a feasibility Analysis, on the basis of a preliminary design of the electric furnace workshop. Elements include: product programme, workshop production capacity of the determination of the entire plant metal balance plan rendering。 material balance and the heat balance calculation。 電爐鋼比例的增長,主要是由于跟高爐轉爐長流程相比,電爐煉鋼具有固定投資小,消耗鐵礦石、焦炭、水等資源少,占地 面積小,可比能耗低,對
