I-CCEFIRE® DEHA Series Isitini esiphezulu se-alumina siwuhlobo lwempahla ephikisayo engathathi hlangothi enokuqukethwe kwe-aluminium ngaphezu kuka-48%. Isitini esiphezulu se-alumina refractory senziwa ngokubala nokubunjwa nge-bauxite nezinye izinto zokusetshenziswa ezinokuqukethwe okuphezulu kwe-alumina. Ngokusho kokuqukethwe okuhlukile kwe-alumina esitini esiphezulu se-alumina, ukumelana kwayo nomlilo, i-refractoriness ngaphansi komthwalo, amandla okucindezela nezinye izinkomba ziyahlukahluka.
Ikhwalithi Yomkhiqizo Ezinzile
Ukulawula okuqinile kwezinto ezingavuthiwe
Lawula okuqukethwe kokungcola, qinisekisa ukuncipha kokushisa okuphansi, futhi uthuthukise ukumelana nokushisa
1. Umnikazi wesisekelo esikhulu sensimbi, okokusebenza kwezimayini, kanye nokukhethwa okuqinile kwezinto zokusetshenziswa.
2. Izinto zokusetshenziswa ezingenayo ziyahlolwa kuqala, bese izinto ezingavuthiwe ezifanele zigcinwe endaweni yokugcina impahla ekhethiwe ukuze kuqinisekiswe ubumsulwa bazo.
3. Izinto zokusetshenziswa ze-CCEFIRE Izitini ze-alumina eziphakeme zinokungcola okuphansi okunama-oxide angaphansi kuka-1%, njengensimbi nensimbi ye-alkali. Ngakho-ke, izitini ze-CCEFIRE High alumina zine-refractoriness ephezulu.
Ukulawulwa kwenqubo yokukhiqiza
Nciphisa okuqukethwe kwamabhola e-slag, qinisekisa ukuhanjiswa kwe-thermal okuphansi, futhi uthuthukise ukusebenza kokufakwa kwe-thermal
1. Isistimu yokuhlanganisa ezenzakalelayo ngokugcwele iqinisekisa ngokugcwele ukuzinza kokwakheka kwempahla eluhlaza kanye nokunemba okungcono kwesilinganiso sempahla eluhlaza.
2. Ngemigqa yokukhiqiza ezenzakalelayo ethuthuke emhlabeni jikelele yeziko lezinga eliphezulu lokushisa, iziko lokufudumeza, nezithando zomlilo ezijikelezayo, izinqubo zokukhiqiza kusukela ezintweni ezingavuthiwe kuya emikhiqizweni eqediwe zingaphansi kokulawulwa kwekhompyutha okuzenzakalelayo, okuqinisekisa ikhwalithi yomkhiqizo ozinzile.
3. Izithando zomlilo ezizenzakalelayo, ukulawulwa kwezinga lokushisa okuzinzile, ukuqhutshwa kokushisa okuphansi kwe-CCEFIRE Izitini ze-alumina eziphakeme, ukusebenza okuhle kakhulu kwe-thermal insulation, ngaphansi kuka-0.5% ekushintsheni komugqa unomphela, ikhwalithi ezinzile, nempilo ende yesevisi.
4. Ukubunjwa okuhlukahlukene kwezitini eziphakeme ze-alumina kungenziwa ngokusho kwemiklamo. Zinobukhulu obunembe ngephutha lokuthi +1mm futhi zilungele amakhasimende ukuthi azifake.
Ikhwalithi yokulawula
Qinisekisa ukuminyana ngobuningi futhi uthuthukise ukusebenza kwe-thermal insulation
1. Ukuthunyelwa ngakunye kunomhloli wekhwalithi ozinikele, futhi umbiko wokuhlola unikezwa ngaphambi kokuhamba kwemikhiqizo evela efektri ukuze kuqinisekiswe ikhwalithi yokuthekelisa yokuthunyelwa ngakunye kwe-CCEFIRE.
2. Ukuhlola okuvela eceleni (okufana ne-SGS, BV, njll.) kwamukelwe.
3. Ukukhiqizwa kuhambisana ngokuqinile nesitifiketi sohlelo lokuphathwa kwekhwalithi ye-ASTM.
4. Ukupakishwa kwangaphandle kwebhokisi ngalinye kwenziwa ngezingqimba ezinhlanu zephepha le-kraft, kanye nokupakisha kwangaphandle + i-pallet,, efanele ukuhamba ibanga elide.
Izici Ezivelele
1. Ukungaguquguquki
I-refractoriness ye-CCEFIRE izitini eziphakeme ze-alumina ziphakeme kunezitini eziphikisayo zobumba nezitini ze-semi-silica, ezifinyelela ku-1750 ~ 1790 ℃, okuwuhlobo lwezinto eziphikisayo zezinga eliphezulu.
2. Layisha ukuthambisa izinga lokushisa
Njengoba imikhiqizo ye-alumina ephezulu ine-Al2O3 ephezulu, ukungcola okuncane, kanye nengilazi encane ye-fusible, izinga lokushisa lokunciphisa umthwalo liphakeme kunalelo lezitini zobumba, kodwa ngenxa yokuthi amakristalu e-mullite awakhi isakhiwo senethiwekhi, izinga lokushisa lokuthambisa umthwalo alikabi phezulu njengezitini ze-silica.
3. Ukumelana ne-slag
Izitini ze-CCEFIRE ezine-alumina ephezulu ziqukethe i-Al2O3 eningi, eduze ne-neutral refractory material, ukuze zikwazi ukumelana nokuguguleka kwe-acid slag kanye ne-alkaline slag. Ngenxa yokuqukethwe kwe-SiO2, ukumelana ne-alkaline slag kubuthakathaka kune-acid slag.
Izitini eziphakeme ze-alumina ezibonakala ngokuzinza okuphezulu kokushisa, ukuqina okuphezulu okungaphezulu kwama-degrees angu-1770, ukumelana ne-slag okuhle, ikakhulukazi okusetshenziselwa isithando somlilo sikagesi, isithando somlilo, isithando somlilo esishisayo, i-ladle, insimbi encibilikisiwe, ihhavini likasimende, ingilazi yomlilo kanye nolunye uhlaka lwesithando somlilo. Isetshenziswa kakhulu ekwenzeni insimbi, ukwenza insimbi, imboni yamakhemikhali, usimende nezinye izimboni.
