Ukuhleleka kwe-Ironmaking Blast kanye Nezimfanelo Zokushisa Ezishisayo

Isingeniso esakhiweni sokuqala sokufakwa kwezinsika zokuqhuma kanye nezinto ezishisayo ezishisayo:

Isithando somlilo siluhlobo lwemishini eshisayo enesakhiwo esiyinkimbinkimbi. Yimishini esemqoka ye-ironmaking futhi inezinzuzo zokukhishwa okukhulu, ukukhiqizwa okuphezulu, kanye nezindleko eziphansi.
Njengoba izinga lokushisa elisebenzayo lengxenye ngayinye yesithando se-blast liphezulu kakhulu, futhi ingxenye ngayinye ifakwa emiphumeleni emishini, okufana nokushayisana kokushisa okushisayo, amazinga okushisa aphezulu okushisa asebenzisa amazinga okushisa aphezulu athambisa ngaphansi kwemithwalo kanye namandla aphezulu aphezulu.
Njengomunye wemishini eyinhloko yesithando esikhazimulayo, isithando esishisayo esishisayo sinikezela ukuqhuma okushisayo okushisa kakhulu esithandweni sokushisa ngokusebenzisa ukushisa kwegesi yokuvutha kanye nemiphumela yokushisa kwezitini. Njengoba ingxenye ngayinye ithwala ukusabela okuphezulu kwegesi yokuhlangana kwegesi, ukuguguleka kothuli okulethwa yigesi, nokushaywa kwegesi okushisayo, ukhonkolo oshisayo oshisayo uvame ukukhetha izitini zokukhanya kwe-ccefire okukhanyayo, ukhonkolo ovimbela ukushisa, nezitini zobumba nezinye izinto ezinamandla amahle emishini.
Ukuze uqinisekise ngokugcwele imiphumela yokufakwa okushisayo kwesithako somlilo, ithobela imigomo yokukhetha izinto ezinokwethenjelwa ngokwezobuchwepheshe, ukufundwa kwayo okushisayo kwesithando esishisayo kanye nokusebenza okuphansi okushisayo okunokusebenza okuhle kwe-infal.
Indlela eyengeziwe yendabuko ukukhetha imikhiqizo yebhodi le-calcium busication, elinale nokwakheka okuqondile kokufakwa okushisayo: izitini ezikhanyayo ezi-aluminium + isakhiwo se-silica-calcium blokhi ngesigqikwa sokufakelwa esishisayo esingama-1000mm acishe abe yi-1000mm.

Lesi sakhiwo sokufakwa okushisayo sinezinkinga ezilandelayo kuhlelo lokusebenza:

A. Izinto zokufakwa kokufakwa okushisayo zinokuqhutshwa okukhulu okushisayo kanye nemiphumela emibi yokufaka okushisayo.
B. Amabhodi e-Silicon-calcium asetshenziswe ku-back lining ungqimba angaphuka kalula, akha izimbobo ngemuva kokuphulwa, futhi adale ukulahleka kokushisa.
C. Ukulahleka okukhulu kokushisa okushisa, okuholela ekungcoleni kwamandla.
D. Amabhodi ase-calcium alithuli ane-absorption eqinile yamanzi, kulula ukuphula, futhi enze kabi ekwakheni.
E. Ukushisa kohlelo lokusebenza kwamabhodi e-calcium aillicate aphansi ngo-600 ℃
Izinto zokufakwa okushisayo ezisetshenziswa esithandweni esivuthayo kanye nesithando saso esishisayo esishisayo kudingeka kube nokusebenza okuhle kokufakelwa okushisayo. Yize ukuthuthuka okushisayo kwamabhodi abunjiwe e-calcium aphansi kunalokho izitini ezibusayo kanye nokusebenza kokufakwa kwe-thermal kwenziwe ngcono, ngenxa ye-calcium silicape board kuphumula kalula ngesikhathi senqubo yokwakha ngenxa yokubuyiselwa kwabo emuva kwemiphumela yokufakelwa kwazo kanye nemiphumela engagculisi. Ngakho-ke, ukuze uthuthukise ukuthuthukisa imiphumela yokufakwa kwe-thermal kwezinsimbi zokuqhuma kwe-metallurgical kanye nezinto ezishisayo ze-blast, ama-ccewool ceramic fiber proub (izitini / amabhodi) ziye zaba yinto efanelekile yokufakelwa kuwo.

Ukuhlaziywa kwama-ceramic fiberboards 'okwenziwa kwezobuchwepheshe kwezobuchwepheshe:

Ccewool ceramic fiberboards asungule ikhwalithi ephezulu ye-Al2o3 + i-SIO2 = 97-99% FIBERS njengezinto zokwakha ezingavuthiwe, ezihlanganiswe nama-Inorganic Binders njengomzimba oyinhloko kanye nezengezo zesikhashana esiphakeme kanye nezithasiselo. Bakhiwa ngokuvusa ama-purping kanye nokuhlunga kwe-vacuum suction. Ngemuva kokuthi imikhiqizo yomisiwe, icutshungulwa ngochungechunge lwemishini yemishini yokuqedela izinqubo zokucubungula, njengokugaya, ukugaya, nokumba ukuqinisekisa ukusebenza komkhiqizo kanye nokunemba okuphezulu kusezingeni eliphakeme kakhulu. Izici zabo zobuchwepheshe eziphambili zifaka:
a. Ukuhlanzeka okuphezulu kwamakhemikhali: okuqukethe ama-oxide angama-97-99 aphezulu ama-oxides anjenge-al2o3 ne-SIO2, eqinisekisa ukumelana nokushisa kwemikhiqizo. Ccewool ceramic fiberboards ayikwazi ukufaka okunye esikhundleni samabhodi asilisa we-calcium asreiling njenge-lining yodonga, kepha futhi asetshenziswe ngqo endaweni eshisayo yezindonga zomlilo ukuze uzihlomise ngokumelana nokuguguleka komoya okuhle.
b. Imiphumela ephansi eshisayo kanye nemiphumela emihle yokufaka okushisayo
c. Amandla aphezulu futhi okulula ukuwasebenzisa: Imikhiqizo inamandla amakhulu acindezelayo futhi aguquguqukayo futhi ayizinto ezingezona ezifuywayo, ngakho-ke zihlangabezana ngokugcwele nezidingo zezinto zokwakha emuva. Zingasetshenziswa kunoma yimaphi amaphrojekthi wokufakelwa ngezidingo zamandla aphezulu, esikhundleni sezinto ezingemuva zokulala kwezingubo zokulala noma ezizwakalayo. Ngaleso sikhathi, ama-fiberbool acutshungulwe i-ceramic ceramic fiberboard anobukhulu obunembile bejometri futhi angasikwa futhi acutshungulwe ngentando. Ukwakhiwa kulula kakhulu, okuxazulula izinkinga zobuqili, ukugcwala kanye nezinga lokulimala kokwakhiwa okuphezulu kwamabhodi e-calcium silicate amabhodi. Banciphise kakhulu isikhathi sokwakha futhi banciphise izindleko zokwakha.
Ngamafuphi, ama-fiberbool ceramic ceramic akhiqizwa yi-vacuum ekwakheka hhayi kuphela izakhiwo ezinhle kakhulu zemishini kanye nobukhulu bejometri obuqondile, kepha futhi ugcina izici ezinhle kakhulu zezinto zokuvikela ukushisa. Bangakwazi ukufaka esikhundleni amabhodi e-calcium alirland futhi basetshenziswe kumasimu wokufakelwa adinga ubulukhuni nokuzethemba kanye nokumelana nomlilo.
