Uchungechunge lwe-CCEFIRE® DEHA Izitini ezijikijelayo ze-alumina ephezulu ziwuhlobo lwezinto ezijikijelayo ezingathathi hlangothi ezinokuqukethwe kwe-aluminium okungaphezu kuka-48%. Izitini ezijikijelayo ze-alumina ephezulu zenziwa nge-calcination kanye nokubumba kusuka ku-bauxite nezinye izinto zokusetshenziswa ezinokuqukethwe okuphezulu kwe-alumina. Ngokusho kokuqukethwe okuhlukile kwe-alumina ezitini ezijikijelayo ze-alumina ephezulu, ukumelana kwayo nomlilo, ukumelana kwayo nomthwalo ngaphansi komthwalo, amandla okucindezela kanye nezinye izinkomba kuyahlukahluka.
Ikhwalithi Yomkhiqizo Ezinzile
Ukulawulwa okuqinile kwezinto zokusetshenziswa
Lawula okuqukethwe kokungcola, qinisekisa ukuncipha kokushisa okuphansi, futhi uthuthukise ukumelana nokushisa
1. Unesisekelo esikhulu se-ore, imishini yokumba yobungcweti, kanye nokukhethwa okuqinile kwezinto zokusetshenziswa.
2. Izinto zokusetshenziswa ezingenayo ziyahlolwa kuqala, bese izinto zokusetshenziswa ezifanele zigcinwa endaweni yokugcina impahla eluhlaza ekhethiwe ukuqinisekisa ubumsulwa bazo.
3. Izinto zokusetshenziswa zezitini ze-CCEFIRE Ezine-alumina ephezulu zinokuqukethwe okuphansi kokungcola okunama-oxide angaphansi kuka-1%, njengensimbi nezinsimbi ze-alkali. Ngakho-ke, izitini ze-CCEFIRE Ezine-alumina ephezulu zinamandla okumelana nokushisa okuphezulu.
Ukulawulwa kwenqubo yokukhiqiza
Nciphisa okuqukethwe kwamabhola e-slag, qinisekisa ukuthi ukushisa kuphansi, futhi uthuthukise ukusebenza kokushisa
1. Uhlelo lokuhlanganisa oluzenzakalelayo ngokuphelele luqinisekisa ngokugcwele ukuzinza kokwakheka kwezinto zokusetshenziswa kanye nokunemba okungcono kwesilinganiso sezinto zokusetshenziswa.
2. Ngemigqa yokukhiqiza ezenzakalelayo ethuthukisiwe emhlabeni wonke yezithando zomhubhe ezishisa kakhulu, izithando zokuthutha, kanye nezithando ezijikelezayo, izinqubo zokukhiqiza kusukela ezintweni zokusetshenziswa kuya emikhiqizweni eqediwe zilawulwa yikhompyutha ngokuzenzakalelayo, okuqinisekisa ikhwalithi yomkhiqizo ezinzile.
3. Izitofu ezizenzakalelayo, ukulawulwa kokushisa okuzinzile, ukuhanjiswa kokushisa okuphansi kwe-CCEFIRE Izitini ze-alumina eziphakeme, ukusebenza kahle kokuvikela ukushisa, ngaphansi kuka-0.5% ekushintsheni komugqa okuhlala njalo, ikhwalithi ezinzile, kanye nokuphila isikhathi eside kwenkonzo.
4. Izimo ezahlukahlukene zezitini ze-alumina eziphakeme zingenziwa ngokwemiklamo. Zinobukhulu obuqondile obunephutha elingu-+1mm futhi zilungele amakhasimende ukuzifaka.
Ikhwalithi yokulawula
Qinisekisa ubuningi obukhulu futhi uthuthukise ukusebenza kokuvikela ukushisa
1. Ukuthunyelwa ngakunye kunomhloli wekhwalithi ozinikele, futhi kunikezwa umbiko wokuhlola ngaphambi kokuhamba kwemikhiqizo efektri ukuqinisekisa ikhwalithi yokuthunyelwa ngakunye kwe-CCEFIRE.
2. Ukuhlolwa komuntu wesithathu (njenge-SGS, i-BV, njll.) kuyamukelwa.
3. Ukukhiqizwa kuhambisana ngokuqinile nesitifiketi sohlelo lokuphathwa kwekhwalithi ye-ASTM.
4. Iphakheji yangaphandle yebhokisi ngalinye yenziwe ngezingqimba ezinhlanu zephepha lokubhaka, kanye nephakheji yangaphandle + iphalethi,, efanelekile ukuthuthwa ibanga elide.
Izici Ezivelele
1. Ukungavuvukali
Ukuqina kwezitini ze-alumina eziphakeme ze-CCEFIRE kuphakeme kunokuqina kwezitini zobumba ezimelana nobumba kanye nezitini ze-semi-silica, kufinyelela ku-1750~1790℃, okuwuhlobo lwezinto zokumelana ezisezingeni eliphezulu.
2. Izinga lokushisa lokuthambisa umthwalo
Njengoba imikhiqizo ene-alumina ephezulu ine-Al2O3 ephezulu, ukungcola okuncane, kanye nengilazi engashibiliki kakhulu, izinga lokushisa lokuthambisa umthwalo liphakeme kunelezitini zobumba, kodwa ngenxa yokuthi amakristalu e-mullite awakhi isakhiwo senethiwekhi, izinga lokushisa lokuthambisa umthwalo alikaphakeme njengezitini ze-silica.
3. Ukumelana ne-slag
Izitini ze-CCEFIRE ezine-alumina ephezulu ziqukethe i-Al2O3 eyengeziwe, eduze nezinto ezingathathi hlangothi ezimelana nokuguguleka, ukuze zikwazi ukumelana nokuguguleka kwe-asidi slag kanye ne-alkaline slag. Ngenxa yokuqukethwe kwe-SiO2, ukumelana ne-alkaline slag kubuthakathaka kunokumelana ne-asidi slag.
Izitini ze-alumina eziphakeme ziphawuleka ngokuqina okuphezulu kokushisa, ukumelana okuphezulu okungaphezu kwama-degrees angu-1770, ukumelana okuhle kwe-slag, ezisetshenziswa kakhulu phezulu kwesithando sikagesi, isithando somshaft, isithando somlilo esishisayo, iladle, insimbi encibilikisiwe, isithando sikasimende, isithando seglasi kanye nezinye izinto zokushisa zesithando. Zisetshenziswa kabanzi ekwenzeni insimbi, ekwenzeni insimbi, embonini yamakhemikhali, kusimende nakwezinye izimboni.
