摘　要:本畢業(yè)設(shè)計是根據(jù)國內(nèi)外電弧爐煉鋼技術(shù)現(xiàn)狀來設(shè)計的，主要任務(wù)是設(shè)計一個年產(chǎn)120萬噸的現(xiàn)代電爐煉鋼車間。該廠以電爐煉鋼車間為基礎(chǔ),設(shè)定兩座85t電弧爐、鋼包爐和VD爐、合金料添加系統(tǒng),直接與連鑄機連接，以及各種公、輔設(shè)施，包括煙氣處理設(shè)備和自動化系統(tǒng)。

　　　本文對電弧爐煉鋼車間全廠金屬平衡，以及煉鋼過程中的物料平衡、熱平衡進行了計算，以及對爐型結(jié)構(gòu)、車間布置進行了設(shè)計計算。

關(guān)鍵詞：煉鋼；電爐；設(shè)計

ABSTRACT:The graduation design is basis of recent status and development of electric arc furnace steelmaking technology at home and abroad，and its main task is design an electric steel meltshop with an annual synthesis productivity of 1.2 million tons steel.The Steel-making Plant is based on electric steel meltshop with two 85-t EAF and LF, VDconverter, alloy addition system, conticaster, plus auxiliary services including fume treatment plant and automation system.

　　Plant,s Metal Balancing,Material Balance and Thermal Malance in metallurgical industry have been described in the paper, structure of furnace design and design details of the technical reform project such as:design mission,annual production program,technology analysis,design calculation of main equipment and general layout of the shop,ete, are also emphatically introduced.
