Inkampani yethu isanda kwethulwa i-anti-oxidationi-graphite i-rotor yokuhlanza eyenziwe nge-high-purity graphite idonse ukunaka kwabantu abaningi emakethe. Ii-rotor yokuhlanza akugcini nje ngokuthuthukisa umphumela wokuhlanzwa kwe-aluminium alloy melt, kodwa futhi kwandisa kakhulu impilo yesevisi yemishini, okuletha izinzuzo ezinkulu zezomnotho emabhizinisini okukhiqiza i-aluminium alloy.
I-anti-oxidationi-rotor yokuhlanza yenziwe nge-high-purity graphite, futhi izinga le-graphite lithinta ngokuqondile ukuqina kwe-rotor. Ngobuchwepheshe obukhethekile bokucubungula kanye nokusetshenziswa kwe-anti-oxidation protective coating ebusweni, impilo yesevisi ye-rotor inwetshwa kusukela ezinsukwini ezingu-30 zendabuko kuya ezinsukwini ezingu-50-60, kuthuthukisa kakhulu ukusebenza kahle kwemishini.
Inhloso eyinhloko yei-rotor yokuhlanza iwukuba ukuhlanza liquid aluminium ingxubevange. Inqubo yokuhlanza ye-aluminium alloy ewuketshezi iyindlela ebalulekile yokuthuthukisa ukusebenza okuphelele kwe-aluminium alloy. Kule nqubo, ai-rotor yokuhlanza isetshenziselwa ukuxuba igesi yokuhlanza nesincibilikisi, bese ivuthela ku-aluminium encibilike ngendlela yomjovo ojikelezayo. Lobu buthathwa njengobuchwepheshe obuphambili kakhulu njengamanje. Umgomo wokusebenza wei-rotor yokuhlanza isekelwe ohlelweni oluhlanganisa i-rotor rod kanye ne-nozzle, ehlakaza i-argon noma i-nitrogen ibe amabhamuza amancane angenakubalwa ngesivinini esikhulu futhi iwahlakaze ensimbi encibilikisiwe. Lawa mabhamuza amunca i-hydrogen nama-oxides ekuncibilikeni ngezimiso zomehluko wengcindezi yegesi kanye nokukhangiswa kwendawo, futhi ekugcineni awakhiphe endaweni encibilikayo ukuze azuze ukuhlanzwa.
Mayelana nokusetshenziswa nokugcinwa, ukunakwa okukhethekile kufanele kukhokhwe kumaphuzu alandelayo:
Umbhobho ojikelezayo wei-rotor yokuhlanza yenziwe nge-high-purity graphite, eklanyelwe ukuhlakaza amabhamuza nokusebenzisa amandla e-centrifugal ukuxuba ngokulinganayo ukugeleza koketshezi lwegesi, ngaleyo ndlela kwandise indawo yokuxhumana nesikhathi phakathi kwamabhamuza noketshezi lwe-aluminium alloy, futhi kuthuthukise umphumela wokuhlanza.
Ngemuva kokucubungula, ukumelana nokushisa okuphezului-rotor yokuhlanza inempilo yesevisi yezinsuku ezingama-55-65 ku-700°C kanye nezinsuku ezingama-25-35 ku-1000°C. Ukusetshenziswa kwe-surface protective coating kwandisa impilo yayo yesevisi ibe yizinsuku ezingama-50-60.
Ukuze kunwetshwe impilo yesevisi ye-i-rotor yokuhlanza, kunconywa ukuthi uyishise kusengaphambili imizuzu engu-5-10 endaweni engaba ngu-100mm kude noketshezi oluwuketshezi ngaphambi kokulucwilisa oketshezini lwe-aluminium ukuze ugweme umthelela wokupholisa ngokushesha ezintweni. Igesi kufanele yethulwe ngaphambi kokuba i-rotor icwiliswe emanzini, futhi ukunikezwa kwegesi kufanele kumiswe ngemva kokuba i-rotor ishiya indawo ye-liquid ukuze ivimbele ukuthi i-nozzle ingavimbeli.
Imbangela enkulu yomonakalo kui-rotor yokuhlanzas i-high-temperature oxidation. I-graphite izobhekana ne-oxidation ebalulekile emoyeni emazingeni okushisa angaphezu kuka-600°C, ukwakha amagesi e-CO ne-CO2, okubangela ukuthi ububanzi be-rotor bunciphe kancane kancane kuze kube yilapho iphuka futhi ingasebenziseki.
Ngokuthuthukisa izinto kanye nokucubungula ubuchwepheshe bei-rotor yokuhlanza, lo mkhiqizo ubonisa ukusebenza okuhle kakhulu kanye nezinzuzo zezomnotho emkhakheni wokuhlanza uketshezi lwe-aluminium, okumaka ukuphakama okusha kubuchwepheshe bokukhiqiza i-aluminium alloy. Izinkampani zokukhiqiza ezikhetha lolu hlobo lwei-rotor yokuhlanza ayikwazi nje ukuthuthukisa ukusebenza kahle kokukhiqiza, kodwa futhi inciphise ngempumelelo izindleko zokugcinwa kwemishini, efanele ukusetshenziswa okubanzi.
