Iarhente yokusulungekisa ialuminiyam, eyaziwa ngokuba yi-aukuguquguquka, licandelo elibalulekileyo kwinkqubo yokusulungekisa ialuminiyam.Idlala indima ebalulekileyo ekucoceni ialuminiyam etyhidiweyo kunye nokususa ukungcola ukunyusa umgangatho wemveliso yokugqibela.
Eyona njongo iphambili ye-aluminiyam yokusulungekisa i-aluminiyam kukuququzelela ukususwa kokungcola okwahlukeneyo okukhoyo kwi-aluminium, njenge-magnesium, i-silicon, kunye nezinye izinto ezingcolileyo zetsimbi.Oku kungcola kunokuchaphazela kakubi iipropati zomatshini, ukubonakala, kunye nokusebenza ngokubanzi kwe-aluminium.
Ii-aluminiyam zokucokisa ii-aluminiyam ngokuqhelekileyo zenziwe ngumxube weetyuwa kunye neekhompawundi ze-fluoride.Ukukhethwa kweekhompawundi ezithile kuxhomekeke kukungcola okukhoyo kunye nesiphumo esifunwayo senkqubo yokucoca.Iikhompawundi ezisetyenziswa ngokuqhelekileyo ziquka i-cryolite (Na3AlF6), i-fluorspar (CaF2), i-alumina (Al2O3), kunye neetyuwa ezahlukeneyo.
Xa i-aluminiyam yokucoca i-agent ifakwe kwi-aluminium etyhidiweyo, yenza uluhlu lwe-slag phezu komhlaba.I-slag isebenza njengesithintelo sokukhusela phakathi kwesinyithi esityhidiweyo kunye nomoya ojikelezayo.Lo mqobo usebenzela iinjongo ezininzi.Okokuqala, ithintela i-aluminiyam ekudibaneni neoksijini, ngaloo ndlela inciphisa ukubakho kwe-oxidation.Ukongezelela, i-slag layer ikhuthaza ukuhlukana kokungcola kwi-aluminium etyhidiweyo, evumela ukuba isuswe ngokulula.
Inkqubo yokusulungekiswa ibandakanya ukulawula ngononophelo ubushushu kunye nokwakheka kwe-aluminiyam etyhidiweyo ukuze kuphuculwe ukusebenza kakuhle kwearhente yokucoca i-aluminiyam.Njengoko ukungcola kusabela ngokuguquguquka, zenza iikhompawundi ezineendawo eziphezulu zokunyibilika kunezinyibilikisiweyo.aluminiyam.Ngenxa yoko, ezi khompawundi zitshona ukuya ezantsi kwi-crucible okanye zidada ukuya phezulu njengenkunkuma, okwenza kube lula ukuzohlula kwi-aluminiyam ecocekileyo.
Ubungakanani be-aluminiyam yokusulungekisa efunekayo ixhomekeke kwizinto ezahlukeneyo, ezifana nokwakheka kunye nobuninzi bobumdaka, inqanaba elinqwenelekayo lokucoceka, kunye nendlela ethile yokucoca esetyenzisiweyo.Kubalulekile ukulinganisa phakathi kokusebenzisa isixa esaneleyo se-flux ukufezekisa ukucocwa okusebenzayo ngelixa unciphisa iindleko.
Ukusetyenziswa okuyimpumelelo kwe-aluminiyam yokucoca i-aluminiyam iphumela kwi-aluminiyam esulungekileyo eneempawu eziphuculweyo zomatshini, ukugqitywa komgangatho ophuculweyo, kunye nokuncitshiswa kokuchaphazeleka kwiziphene.Ialuminiyam esulungekisiweyo ingasetyenziswa kuluhlu olubanzi lwemizi-mveliso, kubandakanywa iimoto, i-aerospace, ulwakhiwo, ukupakisha kunye nombane.
Isishwankathelo, i-aluminiyam yokucoca i-aluminiyam yinto eyimfuneko kwinkqubo yokusulungekisa i-aluminium.Ivumela ukukhutshwa kokungcola, ikhulise umgangatho wemveliso yokugqibela, kwaye iqinisekisa ukuba i-aluminium ihlangabezana nemigangatho efunekayo kwizicelo ezijoliswe kuzo.
