首鋼工學(xué)院成教學(xué)院 本科畢業(yè)設(shè)計 題目: 年產(chǎn) 量 280 萬噸煉鋼生鐵 40 萬噸 鑄造生鐵的煉鐵車間 專題: 高爐專家系統(tǒng) 模型 的應(yīng)用及發(fā)展 首鋼工學(xué)院成教學(xué)院畢業(yè)設(shè)計(論文) 1 年產(chǎn)量 280 萬噸煉鋼生鐵 40 萬噸鑄造生鐵的煉鐵車間 摘要 本設(shè)計是設(shè)計年產(chǎn) 280 萬噸煉鋼生鐵, 40 萬噸鑄造生鐵的高爐煉鐵車間。 在設(shè)計中采用了 2022m3 的高爐 2 座,不設(shè)渣口, 2 個出鐵口,采用矩形出鐵場。送風(fēng)系統(tǒng)采用四座新日鐵式外燃式熱風(fēng)爐,煤氣處理系統(tǒng)采用重力除塵器、文氏管和電除塵。渣鐵處理系統(tǒng)采用拉薩法水淬渣( RASA)處理,特殊情況采用 干渣生產(chǎn),上料系統(tǒng)采用皮帶上料機(jī),保證高爐的不間斷供料。 在設(shè)計中,首先做了物料平衡、熱平衡,爐型的設(shè)計與計算,以及設(shè)備的選擇;設(shè)計中應(yīng)用了許多先進(jìn)的工藝,這些工藝在實行大噴煤技術(shù)提高傳熱效率,節(jié)能,提高生產(chǎn)率方面起了重要的作用。在設(shè)計中,廣泛吸收前人技術(shù)革新和國內(nèi)外科學(xué)研究成果。根據(jù)實際需要及可能性,盡量采用先進(jìn)設(shè)備、結(jié)構(gòu)、材料及新工藝。做到技術(shù)上先進(jìn),經(jīng)濟(jì)上合理,又減少環(huán)境污染。 車間總體布置形式為半島式。 關(guān)鍵詞: 高爐,物料平衡,熱平衡,半島式首鋼工學(xué)院成教學(xué)院畢業(yè)設(shè)計(論 文) 2 Design of an ironmaking workshop with annual output of million tons of steelmaking iron and million tons of Casting iron Abstract The assignment is the design of the million tons annual production capacity of steelmaking pig iron, of blast furnace cast pig iron workshop. I design two 1800 m3 blast furnaces, and set up two tap holes with no slag hole, which use rectangular field of iron. Blast system 4 Nippon external bustion hot stoves, Dust catcher system uses gravity precipitators, venturi tube and electrostatic precipitator. The methods of slag iron processing system use water quenching residue Lhasa (RASA), special circumstances use dry slag productions to deal with. The charging system is using belt feeding machine to ensuring uninterrupting charging of blast furnace. In the design, first of all, calculating the material balance, heat balance, and the furnace structure, as well as the choice of equipment。 the design of the application of a number of advanced technology, these processes in the implementation of large pulverized coal injection technology to enhance heat transfer efficiency, to save energy , to improve productivity ,which played an important role. The design has broadly absorpted technological innovations and the results of scientific research at home and abroad. According to the actual needs and possibilities use advanced equipment as far as possible, advanced structure, advanced materials and so on. Achieve technically advanced and economically rational, and reduce environmental pollution. The form of workshop with the overall layout is peninsula. Key words: blast furnace, material balance, eheat balance, peninsula 首鋼工學(xué)院成教學(xué)院畢業(yè)設(shè)計(論文) 3 目錄 緒論 ........................................................................................ 錯誤 !未定義書簽。 1 高爐冶煉綜合計算 ....................................................................................... 8 概述 .................................................................................................... 8 配料計算 ............................................................................................ 8 原燃料條件 ............................................................................. 8 計算礦石需要量 G 礦 ............................................................ 10 計算熔劑需要量 G 熔 ............................................................ 11 爐渣成分的計算 ................................................................... 12 校核生鐵成分 ....................................................................... 14 物料平衡計算 .................................................................................. 15 風(fēng)量計算 ............................................................................... 15 爐頂煤氣成分及數(shù)量的計算 ............................................... 17 編制物料平衡表 ................................................................... 21 熱平衡計算 ...................................................................................... 22 熱量收入 q 收 ......................................................................... 22 熱量支出 q 支 ......................................................................... 24 熱平衡表 ............................................................................... 27 2 高爐本體設(shè)計 ............................................................................................. 29 高爐爐型 .......................................................................................... 29 爐型設(shè)計與計算 .............................................................................. 29 高爐爐襯設(shè)計 .................................................................................. 33 爐底的爐襯設(shè)計與砌筑 ........................................................ 33 爐缸設(shè)計 的爐 襯設(shè)計 ............................................................ 34 爐腹、爐腰和爐身下部的爐襯設(shè)計 .................................... 35 爐身上部和爐喉的爐襯設(shè)計 ................................................ 37 高爐冷卻設(shè)備 .................................................................................. 38 冷卻設(shè)備的作用 ................................................................... 38 首鋼工學(xué)院成教學(xué)院畢業(yè)設(shè)計(論文) 4 冷卻介質(zhì)及水的軟化 ........................................................... 38 冷卻方式 ............................................................................... 39 高爐冷卻系統(tǒng) ....................................................................... 40 高爐送風(fēng)管路 .................................................................................. 41 熱風(fēng)圍管 ............................................................................... 41 送風(fēng)支管 ............................................................................... 42 直吹管 ................................................................................... 42 風(fēng) 口裝置 ............................................................................... 42 高爐鋼結(jié)構(gòu) ...................................................................................... 43 高爐本體鋼結(jié)構(gòu) ................................................................... 43 爐殼 ....................................................................................... 44 爐體框架 ...........................
