Idizayini kanye nokuguqulwa kwe-fiber layer fiber ye-Ironmaking Blast Furnaces nama-Hot-blast furnaces
Isethulo sesakhiwo sokuqala sokufakelwa kwezithando zomlilo neziqhumane ezishisayo:
Isithando somlilo siwuhlobo lwemishini eshisayo enesakhiwo esiyinkimbinkimbi. Iwumshini oyinhloko wokwenza insimbi futhi inezinzuzo zomkhiqizo omkhulu, ukukhiqiza okuphezulu, nezindleko eziphansi.
Njengoba izinga lokushisa elisebenzayo lengxenye ngayinye yesithando somlilo liphezulu kakhulu, futhi ingxenye ngayinye ingaphansi kwemiphumela yemishini, njengokungqubuzana nomthelela weshaja ewayo, iningi lezinto eziphikisayo ezisebenza endaweni eshisayo zisebenzisa izitini ezikhanyayo ze-CCEFIRE ezifika nezinga lokushisa eliphezulu lokuthambisa ngaphansi komthwalo namandla amahle emishini ezinga eliphezulu.
Njengenye yemishini eyinhloko ehambisana nesithando somlilo, i-hot blast furnace inikeza ukuqhuma okushisayo okushisayo kwesithando somlilo ngokusebenzisa ukushisa okuvela ekushiseni kwegesi yomlilo kanye nemiphumela yokushintshana kokushisa kwe-lattice yezitini. Njengoba ingxenye ngayinye inomphumela wokushisa ophakeme wokushiswa kwegesi, ukuguguleka kothuli olulethwa igesi, kanye nokushiswa kwegesi evuthayo, izithasiselo ezishisayo zivame ukukhetha izitini zokuvikela ukukhanya kwe-CCEFIRE, ukhonkolo ongashisi, izitini zobumba, nezinye izinto ezinamandla okusebenza kahle.
Ukuze kuqinisekiswe ngokugcwele imiphumela yokushisa okushisayo kwendwangu yesithando somlilo, ukuthobela izimiso zokukhetha izinto ezinokwethenjelwa ngokobuchwepheshe, ezongayo nezinengqondo, ulwelwesi lwendawo eshisayo esebenzayo yesithando somlilo esiqhumayo kanye nesithando somlilo saso esishisayo ngokuvamile sikhetha izinto zokufakelwa ezinomoya ophansi we-thermal conductivity kanye nokusebenza okuhle kokushisa.
Indlela yendabuko kakhulu ukukhetha imikhiqizo yebhodi ye-calcium silicate, enalesi sakhiwo esikhethekile sokufakwa kwe-thermal: izitini ezikhanyayo ze-aluminium ephezulu + isakhiwo samabhodi e-silica-calcium enogqinsi lwe-thermal engaba ngu-1000mm.
Lesi sakhiwo se-thermal insulation sinezinkinga ezilandelayo ekusebenzeni:
A. Izinto zokufaka ezishisayo zinezinga eliphezulu le-thermal conductivity kanye nemiphumela engemihle yokufakwa kwe-thermal.
B. Amabhodi e-silicon-calcium asetshenziswa ongqimbeni lwangemuva angaphuka kalula, akhe izimbobo ngemva kokuphuka, futhi abangele ukulahlekelwa ukushisa.
C. Ukulahleka okukhulu kwesitoreji sokushisa, okuholela ekumosheni kwamandla.
D. Amabhodi e-calcium silicate anomunca amanzi aqinile, kulula ukuphuka, futhi awasebenzi kahle ekwakhiweni.
E. Izinga lokushisa lokusetshenziswa kwamabhodi e-calcium silicate liphansi ku-600℃
Izinto zokufakelwa ezishisayo ezisetshenziswa esithandweni somlilo kanye nesithando somlilo saso esishisayo zidinga ukusebenza kahle kokufakwa kwe-thermal. Nakuba i-conductivity yokushisa yamabhodi e-calcium silicate iphansi kunezitini eziphikisayo kanye nokusebenza kokushisa okushisayo kuye kwathuthukiswa, ngenxa yokuphakama komzimba wesithando somlilo kanye nobubanzi obukhulu besithando somlilo, amabhodi e-calcium silicate aphuka kalula ngesikhathi senqubo yokwakha ngenxa yokuqina kwawo, okuholela ekufakweni okungaphelele kwe-back lining kanye nemiphumela engagculisi yokufakelwa. Ngakho-ke, ukuze kuthuthukiswe imiphumela yokushisa eshisayo yezithando zensimbi neziqhumane ezishisayo, imikhiqizo ye-CCEWOOL ye-ceramic fibre (izitini/amabhodi) isiphenduke into efanelekile yokufakwa kuyo.
Ukuhlaziywa kokusebenza kobuchwepheshe kwama-ceramic fiberboards:
I-CCEWOOL Ceramic fiberboards isebenzisa i-AL2O3+SiO2=97-99% yekhwalithi ephezulu yamafayibha njengezinto ezingavuthiwe, ezihlanganiswe nezibophezelo ze-inorganic njengomzimba oyinhloko nezigcwalisi nezithasiselo zezinga eliphezulu lokushisa. Akhiwa ngokunyakazisa kanye nokudonsa kanye nokuhlunga kwe-vacuum suction. Ngemva kokuba imikhiqizo isomisiwe, icutshungulwa ngochungechunge lwemishini yokwenza imishini ukuze kuqedelwe izinqubo zokucubungula, njengokusika, ukugaya, nokubhoboza ukuze kuqinisekiswe ukuthi ukusebenza komkhiqizo nokunemba kobukhulu kusezingeni eliholayo lamazwe ngamazwe. Izici zabo eziyinhloko zobuchwepheshe zihlanganisa:
a. Ukuhlanzeka kwamakhemikhali aphezulu: aqukethe ama-97-99% ama-oxide aphezulu okushisa afana ne-Al2O3 ne-SiO2, eqinisekisa ukumelana nokushisa kwemikhiqizo. I-CCEWOOL Ceramic fiberboards ayikwazi nje ukufaka amabhodi e-calcium silicate njengodonga lwesithando somlilo, kodwa futhi asetshenziswe ngokuqondile endaweni eshisayo yezindonga zesithando somlilo ukuze ahlomise ukumelana nokuguguleka komoya okuhle kakhulu.
b. I-conductivity ephansi yokushisa kanye nemiphumela emihle yokushisa okushisayo: Ngenxa yokuthi lo mkhiqizo ungumkhiqizo we-CCEWOOL we-ceramic fiber okhiqizwa inqubo ekhethekile yokukhiqiza eqhubekayo, unomsebenzi ongcono kunezitini zendabuko ze-diatomaceous zomhlaba, amabhodi e-calcium silicate nezinye izinto ezisekelayo eziyinhlanganisela ye-silicate ekuqhubeni kwayo okuphansi kwe-thermal, imiphumela engcono yokugcina ukushisa, kanye nemiphumela ebalulekile yokonga amandla.
c. Amandla aphezulu futhi kulula ukuwasebenzisa: Imikhiqizo inamandla aphezulu okucindezela futhi aguquguqukayo futhi ayizinto ezingezona i-brittle, ngakho-ke ihlangabezana ngokugcwele nezidingo zezinto eziqinile ze-back back. Angasetshenziswa kunoma yimaphi amaphrojekthi okufakelwa anezidingo zamandla aphezulu, esikhundleni sezinto zokwenziwa zangemuva zezingubo zokulala noma izinsimbi. Ngaleso sikhathi, ama-CCEWOOL Ceramic fiberboards acutshunguliwe anobukhulu obunembile bejometri futhi angasikwa futhi acutshungulwe ngokuthanda kwakhe. Ukwakhiwa kulula kakhulu, okuxazulula izinkinga ze-brittleness, fragility kanye nezinga eliphezulu lokulimala kokwakhiwa kwamabhodi e-calcium silicate. Banciphisa kakhulu isikhathi sokwakha futhi banciphise izindleko zokwakha.
Kafushane, i-CCEWOOL Ceramic fiberboards ekhiqizwa ukwakhiwa kwe-vacuum ayinayo nje kuphela izakhiwo ezinhle kakhulu zemishini kanye nobukhulu obunembile bejiyomethri, kodwa futhi igcina izici ezinhle kakhulu zezinto zokuvikela ukushisa kwe-fibrous. Angakwazi ukufaka esikhundleni samabhodi e-calcium silicate futhi asetshenziswe ezinkambini zokufakelwa ezidinga ukuqina nokuzisekela kanye nokumelana nomlilo.
Isakhiwo sokusetshenziswa samabhodi e-ceramic fiberboards kuma-ayina aqhumayo aqhumayo kanye neziqhumane ezishisayo
Isakhiwo sokusebenza se-CCEWOOL Ceramic fiberboards ezithandweni zokuqhumisa insimbi sisetshenziswa kakhulu njengokusekelwa kwezitini ze-silicon carbide refractory, izitini zobumba ezisezingeni eliphezulu noma izitini eziphikisayo ze-alumina ephezulu, esikhundleni samabhodi e-calcium silicate (noma isitini se-diatomaceous earth).
Isicelo ku-ayina blast furnaces kanye hot blast furnaces
I-CCEWOOL Ceramic fiberboards ingathatha indawo yesakhiwo se-calcium silicate board (noma isitini se-diatomaceous earth), futhi ngenxa yezinzuzo zabo, ezifana ne-conductivity ephansi eshisayo, izinga lokushisa eliphezulu elisetshenziswayo, ukusebenza kahle kwemishini, futhi akukho ukumuncwa kwamanzi, axazulula ngokuphumelelayo izinkinga isakhiwo sokuqala esinazo, isibonelo, imiphumela engemihle yokushisa okushisayo, ukulahlekelwa okukhulu kokushisa, izinga eliphezulu lomonakalo, isevisi ye-calcium silicate ukwakhiwa okufushane kanye ne-insulation board. Bazuze imiphumela emihle kakhulu yohlelo lokusebenza.
