Incazelo ye-Corundum Mullite Castable
I-Corundum mullite refractory castable uhlobo lwezinto zokwakha eziqinile nezingenasimo ezithengiswayo e-RS Company, ezingasetshenziswa kuhhavini wesamente. Ama-castable e-Corundum mullite angenza izakhiwo eziphakeme njengokuqina okuphezulu kokuchoboza, ukuqina kokushisa okuphezulu, ukumelana nokushaqeka kokushisa, ukumelana nokuguguleka kwamakhemikhali elangeni lebhoyila elikhulu lesiteshi samandla kanye neminye imishini yokushisa okuphezulu. I-corundum mullite refractory castable ingasetshenziswa kuhhavini wensimbi, kuhhavini wesamente, kuhhavini wengilazi, kuhhavini wokwenza insimbi, kuhhavini we-ceramic tunnel njalo njalo.
Izakhiwo zeCorundum Mullite Castable
- Amandla aphezulu,
- Ukumelana nokuguguleka okunamandla,
- Ukumelana okuhle nokuguguleka komhlabathi,
- Ukuqina okuhle kakhulu kokushaqeka kokushisa,
- Ukumelana nokushisa okuphezulu.
Inqubo Yokukhiqiza yeCorundum Mullite Castable
Izinto eziyinhloko zokusetshenziswa kwe-corundum mullite castable yi-aluminium oxide aggregate elula, i-mullite ore yemvelo ehlanzekile esezingeni eliphezulu, kanye ne-calcium aluminate cement njenge-bonding agent. I-corundum mullite refractory castable yenziwa ngokushiswa kokushisa okuphezulu yi-furnace yezimboni ethuthukisiwe. Amandla e-corundum mullite flexural kanye namandla okucindezela ayanda kuqala bese ehla bese kuba ngokwanda kwezinga lokushisa lokwelashwa kokushisa. Futhi lapho okuqukethwe kwamandla amancane e-alumina kungu-5%, amandla e-flexural afinyelela phezulu.
Ukwakheka kweCorundum Mullite Castable
Okuqukethwe kwe-Al2O3 kungaphezu kuka-90%, kanti i-corundum mullite insulation castable ne-corundum njengesigaba esiyinhloko sekristalu ixutshwe nama-dispersants afanele, ama-coagulant, imicu yensimbi engagqwali, ehlanganiswa ngokwefomula eqinile. I-corundum mullite castable e-Refractory inezici eziningi, njengamandla okushisa aphezulu, ukumelana nokuguguleka kanye nokulwa nokushisa, ukuqhuba ukushisa okuphezulu, ukumelana nokushaqeka kokushisa, ukumelana nokugqwala, ukuvala kahle kanye nokufinyela kwasekuqaleni.

Ukusetshenziswa kweCorundum Mullite Castable
I-Corundum mullite refractory castable inezici zokwandiswa okufanayo, ukumelana okuhle kakhulu nokushaqeka kokushisa, ukuzinza kwevolumu yokushisa okuphezulu, amandla okushisa aphezulu, ukumelana okuphezulu ngaphansi komthwalo, izinga eliphansi lokuhamba lokushisa eliphezulu, amandla aphezulu okuchoboza, izinga eliphansi lokushintsha kobukhulu obuqondile, ubulukhuni obuphezulu, ukumelana okuhle nokugqwala kwamakhemikhali, ukuqina kwe-spalling kanye nokumelana nokuguguleka. Ngenxa yalezi zinhlamvu, i-corundum mullite insulation castable ihlala isikhathi eside isetshenziswa futhi isetshenziswa kabanzi ezitsheni ezahlukene zezimboni, esithandweni sokushisa okuphezulu nakwezinye izingxenye ezibalulekile zokushisa okuphezulu, njenge:
- Ibhoyila, isithando somlilo, isitofu somlilo esishisayo, isithando somlilo esishisayo,
- Isitofu somhubhe we-ceramic, isitofu sikasimende, isitofu samalahle,
- Umnyango wesithando somlilo, ukuvulwa kokudla, izithando zensimbi, izithando zokwenza insimbi,
- Igumbi lokusha, ulwelwesi oluthambekele,
- Ibhoyila yesiteshi sikagesi esikhulu, i-oven yengilazi.
