Blast furnace steel plant with raw materials for the workshop anizationThe subject of this graduation project for the design of an annual output of tons of pig iron (including steelmaking pig iron 90%, cast iron 10%) of the blast furnace plant process design. This design uses a series of advanced technology, such as whole cooling wall, carbon bricks, high alumina bricks integrated bottom bottom, blast furnace technology, enriched PCI, main task of this design include the blast furnace burden calculation, blast furnace body design, material transport system design, equipment design, blast furnace, blast furnace blower selection, design and calculation of hot stove, iron slag processing systems and gas handling system design and plant layout and so few parts, and part of the process are described.The design part involves the calculation of blast furnace burden calculation, puting blast furnace, blast furnace blowers and brick puting, and the related calculation of internal bustion stove. Part and the hot blast stove blast furnace design in which the design part is the main part of this design.The design options related to the equipment, including blast furnace equipment selection, blast furnace feed system, equipment selection, the choice of blower, iron slag processing systems and gas handling system equipment selection. I hope that advanced technology can be used in a blast furnace to achieve high yield, high quality low。 longevity, environmental protection, the production target.Key words: blast furnace, Stove, process design, equipment 第 i 頁目 錄前 言 ............................................................11 高爐配料計(jì)算 .....................................................2 原始資料 .....................................................2 礦石的選配 ................................................4 原始資料的整理 ...............................................4 冶煉條件的確定 ...............................................4 煤氣的成分和數(shù)量計(jì)算 .....................................12 物料平衡表的編制 .........................................15 熱平衡 ......................................................16 計(jì)算熱量收入項(xiàng) ...........................................16 計(jì)算熱量支出項(xiàng) ...........................................17 根據(jù)以上計(jì)算列出熱量平衡表 ...............................20 高爐熱工指標(biāo)的分析 .......................................212 高爐本體設(shè)計(jì) ....................................................22 高爐內(nèi)型相關(guān)計(jì)算 ............................................22 高爐內(nèi)襯設(shè)計(jì) ................................................25 爐底 .....................................................25 爐缸 .....................................................26 爐腹 .....................................................26 爐腰 .....................................................27 爐身 .....................................................27 高爐爐殼和高爐基礎(chǔ) ..........................................32 高爐爐殼 .................................................32 高爐基礎(chǔ) .................................................33 爐體設(shè)備 .....................................................34 爐體冷卻設(shè)備 .............................................34 風(fēng)口水套 .................................................35 鐵口套 ...................................................35 爐喉鋼磚 .................................................35 爐頂保護(hù)板 ...............................................353 料運(yùn)系統(tǒng)計(jì)算及裝料布料設(shè)備 ......................................36 貯礦槽 .......................................................36 平面布置 .................................................36 槽上運(yùn)輸方式 .............................................36 第 ii 頁 儲(chǔ)礦槽工藝參數(shù) ...........................................36 槽下供料 .................................................36 料坑設(shè)備 ....................................................37 碎焦運(yùn)送設(shè)施 ................................................38 上料設(shè)備 ....................................................384 高爐鼓風(fēng)機(jī)的選擇 ................................................39 高爐鼓風(fēng)量及鼓風(fēng)壓力的確定 ..................................39 高爐入爐風(fēng)量 .............................................39 鼓風(fēng)機(jī)出口風(fēng)量 ...........................................39 高爐鼓風(fēng)壓力 .............................................40 高爐鼓風(fēng)機(jī)能力的確定 ........................................40 大氣狀況對(duì)高爐鼓風(fēng)的影響 .................................40 鼓風(fēng)機(jī)工況的計(jì)算 .........................................40 鼓風(fēng)機(jī)的選擇 .............................................41 高爐鼓風(fēng)機(jī)的工藝過程 ........................................425 熱風(fēng)爐 ..........................................................43 計(jì)算的原始數(shù)據(jù) ..............................................43 燃燒計(jì)算 ..................................................
