I-CCEFIRE® DEHA Series Izitini eziphakeme ze-alumina ezicasulayo ziwuhlobo lwezinto ezingathathi hlangothi zokuphikisa ezinokuqukethwe kwe-aluminium okungaphezu kwama-48%. Izitini eziphakeme ze-alumina ezikhanyayo zenziwa ngokubala nokubumba kusuka ku-bauxite nezinye izinto zokusetshenziswa ezinokuqukethwe okuphezulu kwe-alumina. Ngokuya ngokuqukethwe okuhlukile kwe-alumina kuzitini eziphakeme ze-alumina, ukumelana nomlilo, ukuphindisela okungaphansi kokulayishwa, amandla acindezelayo nezinye izinkomba ziyahlukahluka.
Ikhwalithi Yomkhiqizo Oqinile
Ukulawulwa okuqinile kwezinto zokusetshenziswa
Lawula okuqukethwe okungcolile, qinisekisa ukuncipha okuphansi okushisayo, futhi uthuthukise ukumelana nokushisa
1. Yiba nesisekelo sensimbi enkulu, imishini yezimayini esezingeni elifanele, nokukhethwa okuqinile kwezinto zokusetshenziswa.
2. Izinto zokusetshenziswa ezingenayo zihlolwa kuqala, bese kuthi izinto zokusetshenziswa ezifanelekayo zigcinwe endaweni yokugcina impahla ekhethiwe ukuze kuqinisekiswe ubumsulwa bazo.
3. Izinto zokusetshenziswa zezitini ze-CCEFIRE High alumina zinokungcola okuphansi okuqukethwe okunama-oxide angaphansi kuka-1%, njenge-iron nezinsimbi ze-alkali. Ngakho-ke, izitini ze-CCEFIRE High alumina zine-refractoriness ephezulu.
Inqubo Yokulawula inqubo
Nciphisa okuqukethwe kwamabhola e-slag, qinisekisa ukuqhutshwa okuphansi kokushisa, futhi uthuthukise ukusebenza kokufakwa kwe-thermal
1. Uhlelo oluzenzakalelayo lokubhaka luqinisekisa ngokuphelele ukuzinza kokwakhiwa kwempahla eluhlaza kanye nokunemba okungcono kunani lezinto ezingavuthiwe.
2. Ngemigqa yokukhiqiza ezenzakalelayo yamazwe omhlaba esezingeni eliphakeme lamathunzi, iziko lokuhamba, namahhavini ajikelezayo, izinqubo zokukhiqiza kusuka ezintweni ezingavuthiwe kuya emikhiqizweni eqediwe zingaphansi kokulawulwa okuzenzakalelayo kwekhompyutha, ukuqinisekisa ikhwalithi yomkhiqizo ozinzile.
3. Amofoji azenzakalelayo, ukulawulwa kokushisa okuzinzile, ukuqhutshwa okushisayo okuphansi kweCCEFIRE Izitini eziphakeme ze-alumina, ukusebenza okuhle kakhulu kwe-thermal, ngaphansi kuka-0.5% ekushintsheni kolayini unomphela, ikhwalithi ezinzile, nempilo yesevisi ende.
4. Izinhlobo ezahlukahlukene zezitini eziphakeme ze-alumina zingenziwa ngokuya ngemiklamo. Zinobukhulu obuqondile ngephutha le- + 1mm futhi zilungele ukuthi amakhasimende azifake.
Ikhwalithi yokulawula
Qinisekisa ukuminyana ngobuningi futhi uthuthukise ukusebenza kokufakwa kwe-thermal
1. Ukuthunyelwa ngakunye kunomhloli wekhwalithi ozinikele, futhi kunikezwa umbiko wokuhlolwa ngaphambi kokuhamba kwemikhiqizo efektri ukuqinisekisa ikhwalithi yokuthunyelwa kokuthunyelwa ngakunye kweCCEFIRE.
2. Ukuhlolwa okuvela eceleni (njenge-SGS, BV, njll.) Kuyamukelwa.
3. Ukukhiqizwa kuhambisana ngokuqinile nesitifiketi sokuphathwa kwekhwalithi ye-ASTM.
4. Ukupakisha kwangaphandle kwebhokisi ngalinye kwenziwa ngezingqimba ezinhlanu zephepha le-kraft, kanye nokupakisha kwangaphandle + pallet ,, efanelekile ukuthuthwa kwebanga elide.
Izici ezivelele
1. Refractoriness
Ukuphinda kukhanye kwezitini eziphakeme ze-CCEFIRE ze-alumina kuphakeme kunezitini ezakhiwe ngobumba nezitini ezinesi-silica, ezifinyelela ku-1750 ~ 1790 ℃, okuluhlobo lwezinto zokuphikisa ezisezingeni eliphakeme.
2. Layisha ukushisa okuthambile
Njengoba imikhiqizo ene-alumina ephezulu ine-Al2O3 ephezulu, ukungcola okuncane, nengilazi engacoleki kangako, izinga lokushisa lokuthambisa umthwalo liphakeme kunalelo lezitini zobumba, kepha ngenxa yokuthi amakristalu e-mullite awenzi isakhiwo senethiwekhi, izinga lokushisa lokuthambisa umthwalo alikaphakeme njengokuthi izitini zesilica.
3. Ukumelana kweSlag
Izitini ze-CCEFIRE eziphakeme ze-alumina ziqukethe i-Al2O3 eningi, eduze kwento ephikisayo engathathi hlangothi, ukuze bakwazi ukumelana nokuguguleka kwe-acid slag ne-alkaline slag. Ngenxa yokuqukethwe kwe-SiO2, ukumelana ne-alkaline slag kubuthakathaka kune-acid slag.
Izitini eziphakeme ze-alumina ezibonakala ngokuzinza okuphezulu okushisayo, ukuphindisela okuphezulu ngaphezulu kwama-degree ayi-1770, ukumelana okuhle kwe-slag, ikakhulukazi okusetshenziselwa isithando somlilo sikagesi, isithando somlilo, isithando somlilo esishisayo, ukhamba, insimbi encibilikisiwe, ikilin kusimende, ingilazi yesikhuni nezinye izinto zokushisa ezishisayo. Isetshenziswa kabanzi ekwenzeni insimbi, ukwenziwa kwensimbi, imboni yamakhemikhali, usimende nezinye izimboni.
