And in accordance with domestic and international steelmaking technology, development trends, development of steel products, select the advanced and there is greater room for development of the shortflow process: scrap → Converter → continuous casting. Design to new technology, the principle of high efficiency, fully reflects the advanced, flexible, multifunction features, with sustainability. Includes design specifications submitted by a (Including thematic and Metallurgy asked all foreign documents related article), Convertertype plans, the workshop floor plan and sections of the piece. Keywords: converter, steelmaking, continuous casting, process design 第 III 頁 目 錄 緒論 .............................................................................................................................. 1 1 轉(zhuǎn)爐煉鋼廠設(shè)計(jì)方案 .............................................................................................. 4 轉(zhuǎn)爐車間生產(chǎn)能力的確定 ................................................................................ 4 主要鋼種的選擇 ................................................................................................ 4 工藝流程 ............................................................................................................ 4 車間組成 ............................................................................................................ 5 主廠房工藝布置 ................................................................................................ 5 原料跨布置 .................................................................................................. 5 爐子跨的布置 .............................................................................................. 6 精煉跨的布置 .............................................................................................. 6 澆注跨與出坯跨 .......................................................................................... 6 原材料的供應(yīng)及設(shè)備 ........................................................................................ 7 廢鋼的供應(yīng) .................................................................................................. 7 散狀材料的供應(yīng) .......................................................................................... 7 氧氣的供應(yīng)及設(shè)備 ............................................................................................ 8 2 物料平衡與熱平衡 .............................................................................................. 10 物料平衡計(jì)算 .................................................................................................. 10 計(jì)算所需原始數(shù)據(jù) .................................................................................... 10 物料平衡基本項(xiàng)目 .................................................................................... 12 計(jì)算步驟 .................................................................................................... 12 熱平衡計(jì)算 ...................................................................................................... 23 計(jì)算所需原始數(shù)據(jù)： ................................................................................ 23 計(jì)算步驟： ................................................................................................ 25 3 頂?shù)讖?fù)吹轉(zhuǎn)爐爐型設(shè)計(jì) ........................................................................................ 30 爐型設(shè)計(jì) .......................................................................................................... 30 原始條件 .................................................................................................... 30 熔池尺寸的計(jì)算 ........................................................................................ 30 爐帽尺寸的確定 ........................................................................................ 31 爐容比的確定 ............................................................................................ 32 爐身尺寸的確定 ........................................................................................ 32 出鋼口的尺寸設(shè)計(jì) .................................................................................... 32 爐襯尺寸的確定 ........................................................................................ 33 爐子高寬比 ................................................................................................ 33 第 IV 頁 氧槍設(shè)計(jì) .......................................................................................................... 34 氧槍噴頭設(shè)計(jì) ............................................................................................ 34 氧槍水冷系統(tǒng) .................................................................................................. 37 底部供氣構(gòu)件的設(shè)計(jì) ............................................
