Idizayini kanye Noguquko lwengqimba yokwahlukanisa insimbi ye-Ironmaking Blast Furnaces kanye ne-Hot-blast furnace
Isingeniso esakhiweni sokuqala sokuvikela ukushisa kwamakhaza namakhaza ashisayo:
Isithando somlilo luhlobo lwezinto ezishisayo ezinesakhiwo esiyinkimbinkimbi. Iyisetshenziswa esiyinhloko sokwenza i-iron futhi inezinzuzo zokukhipha okukhulu, ukukhiqiza okuphezulu, nezindleko eziphansi.
Njengoba izinga lokushisa elisebenzayo lengxenye ngayinye yesithando somlilo liphezulu kakhulu, futhi ingxenye ngayinye ibhekene nemiphumela yemishini, njengokuxabana nomthelela wenkokhiso ewayo, iningi lezindawo ezishisayo ezisebenzisa i-CCEFIRE izinga lokushisa eliphakeme lezitini ezizayo ngamazinga okushisa aphezulu okuthambisa ngaphansi komthwalo namandla amahle we-high-temp mechanical.
Njengomunye wemishini eyinhloko yokulekelelwa kwesithando somlilo, isithando somlilo esishisayo sinikeza ukuqhuma okushisayo okuphezulu esithandweni sokuqhuma ngokusebenzisa ukushisa okuvela emlilweni womlilo wegesi kanye nemiphumela yokushintshana ngokushisa kweleti lezitini. Njengoba ingxenye ngayinye ithwala ukusabela okuphezulu kwesikhashana somlilo wegesi, ukuguguleka kothuli okulethwa yigesi, nokushaywa kwegesi yomlilo, izindawo ezishisayo ezingaphezulu zivame ukukhetha izitini zokuvikela ukukhanya zeCCEFIRE, ukhonkolo ongamelana nokushisa, izitini zobumba, nokunye izinto ezinamandla amahle wokukhanda.
Ukuze kuqinisekiswe ngokugcwele imiphumela yokufakwa kokushisa kwesithambo sesithando somlilo, ngokulandela imigomo yokukhetha izinto ezinokwethenjelwa ngokwezobuchwepheshe, ezongayo nezizwakalayo, ulwelwesi lwendawo esebenzayo eshisayo yesithando somlilo kanye nesithando sayo esishisayo somlilo kuvame ukukhetha izinto zokuvikela ukuqhuba okushisayo okuphansi nokusebenza okuhle kokufakwa.
Indlela yendabuko eyengeziwe ukukhetha imikhiqizo yebhodi ye-calcium silicate, enalesi sakhiwo esithile sokushisa okushisayo: izitini ezikhanyayo eziphezulu ze-aluminium + isakhiwo samabhodi we-silica-calcium anokuqina kokushisa okungaba ngu-1000mm.
Lesi sakhiwo sokufudumeza sinezici ezilandelayo ekusetshenzisweni:
Izinto zokwakha zokushisa ezishisayo zinokuqhutshwa okukhulu kokushisa nemiphumela engemihle yokushisa.
B. Amabhodi e-silicon-calcium asetshenziswe kungqimba lwendwangu engemuva angagqashuka kalula, enze izimbobo ngemuva kokuphuka, futhi abangele ukushisa kokushisa.
C. Ukulahleka okukhulu kokugcina ukushisa, okuholela ekuchithekeni kwamandla.
D. Amabhodi e-calcium silicate anokumunca amanzi okuqinile, kulula ukuwaphula, futhi enza kabi ekwakhiweni.
E. Ukushisa kwesicelo samabhodi e-calcium silicate kuphansi kuma-600 ℃
Izinto zokwakheka ezishisayo ezisetshenziswe esithandweni sokuqhuma kanye nesithando saso esishisayo sokushisa kudingeka ukuthi kube nokusebenza okuhle kokushisa okushisayo. Yize ukuqhutshwa okushisayo kwamabhodi e-calcium silicate kungaphansi kunalokho okwenziwe ngezitini ezikhombayo futhi ukusebenza kwe-thermal kuthuthukisiwe, ngenxa yokuphakama kwesithando somzimba esikhulu nobubanzi besithando somlilo, amabhodi e-calcium silicate aphuka kalula ngesikhathi senqubo yokwakha ngenxa yabo ubuntekenteke, okuholela ekwambekeni okungaphakathi okungaphelele emuva kanye nemiphumela yokugcwala engagculisi. Ngakho-ke, ukuze kuqhutshekwe kuthuthukiswe imiphumela yokufakwa kwemishini eshisayo yamathambo we-metallurgical blast kanye namahhotela okushisa, i-CCEWOOL imikhiqizo ye-ceramic fiber (izitini / amabhodi) seyiphenduke into efanelekile yokufakwa kuyo.
Ukuhlaziywa kokusebenza kobuchwepheshe be-ceramic fiberboards:
Ama-fiberboard e-ceramic e-CCEWOOL amukela i-AL2O3 ephezulu + ne-SiO2 esezingeni eliphakeme njenge-97-99% yemicu njengezinto zokusetshenziswa, kuhlanganiswe nezibophelelo ezingajwayelekile njengomzimba oyinhloko nokugcwalisa okunamandla aphezulu nezithasiselo. Akhiwa ngokudlidliza nokugaya kanye nokuhlanza kokuhlanza. Ngemuva kokuthi imikhiqizo isomisiwe, icutshungulwa ngochungechunge lwemishini yokuqothula ukuqedela izinqubo zokucubungula, ezifana nokusika, ukugaya, nokumba ukuze kuqinisekiswe ukuthi ukusebenza komkhiqizo nokunemba okuyisilinganiso kusezingeni lokuhola lomhlaba jikelele. Izici zabo zobuchwepheshe eziyinhloko zifaka:
a. Ukuhlanzeka kwamakhemikhali okuphezulu: okuqukethe ama-oxide aphezulu okushisa angama-97-99% njenge-Al2O3 ne-SiO2, eqinisekisa ukumelana nokushisa kwemikhiqizo. I-CCEWOOL fiberboard yama-ceramic ayikwazi ukufaka kuphela amabhodi e-calcium silicate njengothango lwesithando somlilo, kepha futhi ingasetshenziswa ngqo ebusweni obushisayo bezindonga zesithando ukuze ibahlomelele ngokumelana nokuguguleka komoya okuhle kakhulu.
b. Ukuqhutshwa okuphansi kokushisa nemiphumela emihle yokufaka okushisayo: Ngoba lo mkhiqizo yi-CCEWOOL ceramic fiber product ekhiqizwa inqubo ekhethekile yokukhiqiza eqhubekayo, inokusebenza okungcono kunezitini zomhlaba zendabuko ezi-diatomaceous, amabhodi e-calcium silicate nezinye izinto zokweseka i-silicate ezintweni eziphansi ezishisayo ukuqhuba, imiphumela engcono yokulondolozwa kokushisa, nemiphumela yokonga amandla ebalulekile.
c. Amandla aphakeme futhi asebenziseka kalula: Imikhiqizo inamandla aphezulu okucindezela nokuguquguquka futhi ayizinto ezingekho brittle, ngakho-ke zihlangabezana ngokugcwele nezidingo zezinto zokwakha ulayini onzima emuva. Zingasetshenziswa kunoma yimaphi amaphrojekthi we-insulation anezidingo zamandla aphezulu, esikhundleni sezinto zokulala zangemuva zezingubo zokulala noma ezithandwayo. Okwamanje, ama-fiberboards e-ceramic e-CCEWOOL asetshenzisiwe anezilinganiso ezinembile zejometri futhi angasika futhi acutshungulwe ngokuthanda. Ukwakhiwa kulula kakhulu, okuxazulula izinkinga zokuqina, ubuhlalu kanye nezinga eliphezulu lokulimala kokwakhiwa kwamabhodi e-calcium silicate. Zifinyeza kakhulu isikhathi sokwakha futhi zinciphise nezindleko zokwakha.
Ngokufingqa, i-CCEWOOL fiberboard ebunjiwe ekhiqizwa nge-vacuum yakha hhayi nje inezakhiwo ezinhle kakhulu zobukhulu nobukhulu be-geometric, kepha futhi igcina nezimpawu ezinhle kakhulu zezinto zokuvikela ukushisa eziyimicu. Bangathatha indawo yamabhodi e-calcium silicate futhi bangafakwa ezinkambeni zokwambathisa ezidinga ukuqina nokuzisekela nokumelana nomlilo.
Isakhiwo sohlelo lokusebenza lwama-fiberboard e-ceramic kumathangi wokuqhuma kwensimbi namakhishi ashisayo wokuqhuma
Isakhiwo sesicelo se-CCEWOOL fiberboard yamabhodlela e-ironmaking blast ovens sisetshenziswa kakhulu njengokwesekwa kwezitini ze-silicon carbide, izitini zobumba ezisezingeni eliphakeme noma izitini eziphakeme ze-alumina, ezithatha indawo yamabhodi e-calcium silicate (noma izitini zomhlaba ze-diatomaceous).
Isicelo kumakhemikhali wokuqhuma kwensimbi nakumafutha ashisayo wokuqhuma
Ama-fiberboards e-CCEWOOL ceramic angathatha isikhundla sokwakhiwa kwamabhodi e-calcium silicate (noma isitini somhlaba esine-diatomaceous), futhi ngenxa yezinzuzo zawo, njengokuqhuba okuphansi kokushisa, ukushisa okuphezulu okusetshenziswayo, ukusebenza kahle kwemishini, futhi akukho ukumuncwa kwamanzi, zixazulula ngempumelelo izinkinga ukwakheka kwangempela kunesibonelo, imiphumela emibi yokufakwa kokushisa, ukulahleka okukhulu kokushisa, izinga lokulimala eliphakeme lamabhodi e-calcium silicate, ukusebenza okungakhi kahle, kanye nempilo yesevisi emfushane yolwelwesi lokuvala. Bazuze imiphumela emihle kakhulu yohlelo lokusebenza.
