Umklamo kanye nokuguqulwa kwefayibha yesendlalelo sokushisa ye-Ironmaking Blast Furnaces kanye ne-Hot-blast furnaces
Isingeniso esakhiweni sokuqala sokushisa sama-blast furniture nama-hot-blast furniture:
Isithando somlilo esiqhumayo uhlobo lwemishini yokushisa enesakhiwo esiyinkimbinkimbi. Siyimishini eyinhloko yokwenza insimbi futhi inezinzuzo zokukhiqiza okukhulu, ukukhiqiza okuphezulu, kanye nezindleko eziphansi.
Njengoba izinga lokushisa lokusebenza lengxenye ngayinye yesithando somlilo liphezulu kakhulu, futhi ingxenye ngayinye ibhekene nemiphumela yemishini, njengokungqubuzana kanye nomthelela weshaja ewayo, iningi lama-refractories ashisayo asebenzisa izitini zokukhanya ze-CCEFIRE ezihambisana namazinga okushisa aphezulu okuthambisa ngaphansi komthwalo kanye namandla amahle emishini esezingeni eliphezulu.
Njengenye yemishini eyinhloko yokusekela yesithando somlilo, isithando somlilo esishisayo sinikeza isithando somlilo esishisayo esishisayo esithandweni somlilo ngokusebenzisa ukushisa okuvela ekushisweni kwegesi yesithando somlilo kanye nemiphumela yokushintshana kokushisa kwe-lattice yezitini. Njengoba ingxenye ngayinye inemiphumela yokushisa okuphezulu kokushiswa kwegesi, ukuguguleka kothuli olulethwa yigesi, kanye nokukhuhla igesi evuthayo, ama-refractories angaphezulu ashisayo avame ukukhetha izitini zokushisa zokukhanya ze-CCEFIRE, ukhonkolo omelana nokushisa, izitini zobumba, nezinye izinto ezinamandla amahle okusebenza.
Ukuze kuqinisekiswe ngokugcwele imiphumela yokushisa kwe-lining yesithando somlilo, kulandelwa izimiso zokukhetha izinto ezithembekile, ezongayo nezinengqondo, ulwelwesi lwendawo eshisayo esebenzayo yesithando somlilo somlilo kanye nesithando saso somlilo esishisayo ngokuvamile lukhetha izinto zokushisa ezinokushisa okuphansi kanye nokusebenza okuhle kokushisa.
Indlela evamile ukukhetha imikhiqizo yebhodi le-calcium silicate, enalesi sakhiwo esithile sokuvikela ukushisa: izitini zokukhanya ze-aluminium ephezulu + isakhiwo samabhodi e-silica-calcium anobukhulu bokuvikela ukushisa obungaba ngu-1000mm.
Lesi sakhiwo sokushisa sinezinkinga ezilandelayo ekusetshenzisweni:
A. Izinto zokuvikela ukushisa zine-conductivity enkulu yokushisa kanye nemiphumela emibi yokuvikela ukushisa.
B. Amabhodi e-silicon-calcium asetshenziswa ongqimbeni lwangemuva angaphuka kalula, akhe izimbobo ngemva kokuphuka, futhi abangele ukulahlekelwa ukushisa.
C. Ukulahlekelwa okukhulu kwesitoreji sokushisa, okuholela ekuchithekeni kwamandla.
D. Amabhodi e-calcium silicate anomuncwa wamanzi oqinile, kulula ukuwaphula, futhi awenzi kahle ekwakheni.
E. Izinga lokushisa lokusetshenziswa kwamabhodi e-calcium silicate liphansi ku-600℃
Izinto zokufaka ukushisa ezisetshenziswa ku-blast furnace kanye ne-hot blast furnace yayo kudingeka zibe nokusebenza okuhle kokufaka ukushisa. Nakuba ukuhanjiswa kokushisa kwamabhodi e-calcium silicate kuphansi kunokwezitini eziphikisayo futhi ukusebenza kokufaka ukushisa kuthuthukisiwe, ngenxa yokuphakama komzimba we-furnace enkulu kanye nobubanzi obukhulu be-furnace, amabhodi e-calcium silicate aphuka kalula ngesikhathi senqubo yokwakha ngenxa yobuthakathaka bawo, okuholela ekufakweni kokufakwa kodonga olungemuva olungaphelele kanye nemiphumela yokufakwa kodonga engagculisi. Ngakho-ke, ukuze kuthuthukiswe imiphumela yokufakwa kokushisa kwama-metallurgical blast furnace kanye nama-hot blast furnace, imikhiqizo ye-CCEWOOL ceramic fiber (izitini/amabhodi) ibe yinto efanelekile yokufakwa kodonga kuzo.
Ukuhlaziywa kokusebenza kobuchwepheshe kwamabhodi e-ceramic fiberboard:
Ama-fiberboard e-ceramic e-CCEWOOL asebenzisa imicu ye-AL2O3+SiO2=97-99% esezingeni eliphezulu njengezinto zokusetshenziswa, ehlanganiswe nezihlanganisi ezingaphili njengomzimba oyinhloko kanye nezigcwalisi kanye nezengezo ezishisa kakhulu. Zakhiwa ngokuxubha kanye nokudonsa kanye nokuhlunga nge-vacuum suction. Ngemva kokuba imikhiqizo isomisiwe, icutshungulwa ngochungechunge lwemishini yokugaya ukuze kuqedwe izinqubo zokucubungula, njengokusika, ukugaya, kanye nokubhoboza ukuqinisekisa ukuthi ukusebenza komkhiqizo kanye nokunemba kobukhulu kusezingeni eliphambili lomhlaba wonke. Izici zabo zobuchwepheshe eziyinhloko zifaka:
a. Ubumsulwa obuphezulu bamakhemikhali: aqukethe ama-oxide angu-97-99% okushisa okuphezulu njenge-Al2O3 ne-SiO2, okuqinisekisa ukumelana nokushisa kwemikhiqizo. Ama-fiberboard e-ceramic e-CCEWOOL awakwazi nje ukufaka esikhundleni samabhodi e-calcium silicate njenge-furnace wall lining, kodwa futhi angasetshenziswa ngqo ebusweni obushisayo bezindonga zesithando ukuze ahlonyiswe ngokumelana okuhle nokuguguleka komoya.
b. Ukushisa okuphansi kanye nemiphumela emihle yokushisa: Ngenxa yokuthi lo mkhiqizo uwumkhiqizo we-ceramic fiber we-CCEWOOL okhiqizwa inqubo ekhethekile yokukhiqiza eqhubekayo, usebenza kangcono kunezitini zomhlaba zendabuko ze-diatomaceous, amabhodi e-calcium silicate kanye nezinye izinto ezisekelayo ze-silicate ezihlanganisiwe ekushiseni kwawo okuphansi, imiphumela engcono yokulondolozwa kokushisa, kanye nemiphumela ebalulekile yokonga amandla.
c. Amandla aphezulu futhi kulula ukuyisebenzisa: Imikhiqizo inamandla aphezulu okucindezela nokuguquguquka futhi ayizinto zokwakha ezingabonakali kahle, ngakho-ke ihlangabezana ngokugcwele nezidingo zezinto zokwakha eziqinile ngemuva. Zingasetshenziswa kunoma yimiphi imisebenzi yokuvikela enezidingo zamandla aphezulu, esikhundleni sezinto zokwakha ezingemuva zezingubo zokulala noma amafelt. Okwamanje, amabhodi e-fiberboard e-CCEWOOL acutshunguliwe anobukhulu obunembile bejometri futhi anganqunywa futhi acutshungulwe ngokuthanda kwawo. Ukwakhiwa kulula kakhulu, okuxazulula izinkinga zobuthakathaka, ubuthakathaka kanye nezinga eliphezulu lomonakalo wokwakha kwamabhodi e-calcium silicate. Afinyeza kakhulu isikhathi sokwakha futhi anciphise izindleko zokwakha.
Ngamafuphi, amabhodi e-fiberboard e-ceramic e-CCEWOOL akhiqizwa ngokwakhiwa kwe-vacuum awagcini nje ngokuba nezakhiwo ezinhle kakhulu zemishini kanye nobukhulu obuqondile bejometri, kodwa futhi agcina izici ezinhle kakhulu zezinto zokuvimbela ukushisa ezine-fibrous. Angathatha indawo yamabhodi e-calcium silicate futhi asetshenziswe ezinkambeni zokuvimbela ezidinga ukuqina nokuzisekela kanye nokumelana nomlilo.
Isakhiwo sokusetshenziswa kwama-fiberboard e-ceramic kuma-fireworks okwenziwa ngensimbi kanye nama-hot blast furnaces
Isakhiwo sokusetshenziswa kwama-fiberboard e-ceramic e-CCEWOOL ezitsheni zomlilo sisebenzisa kakhulu ukusekela izitini eziphikisayo ze-silicon carbide, izitini zobumba ezisezingeni eliphezulu noma izitini eziphikisayo ze-alumina ephezulu, esikhundleni samabhodi e-calcium silicate (noma izitini zomhlaba ze-diatomaceous).
Ukusetshenziswa kwezithando zokuqhuma ezenziwe ngensimbi kanye nezithando zokuqhuma ezishisayo
Ama-fiberboard e-ceramic e-CCEWOOL angathatha indawo yesakhiwo samabhodi e-calcium silicate (noma izitini zomhlaba ze-diatomaceous), futhi ngenxa yezinzuzo zawo, njengokuqhuba ukushisa okuphansi, izinga lokushisa eliphezulu lokusetshenziswa, ukusebenza kahle komshini wokugaya, kanye nokungamuncwa kwamanzi, axazulula ngempumelelo izinkinga isakhiwo sokuqala esinazo, isibonelo, imiphumela emibi yokushisa, ukulahlekelwa ukushisa okukhulu, izinga eliphezulu lomonakalo wamabhodi e-calcium silicate, ukusebenza okubi kokwakhiwa, kanye nokuphila kwesikhathi esifushane kwe-insulation lining. Athole imiphumela emihle kakhulu yokusetshenziswa.
