Kugwiritsa ntchito aluminiyumu kuyenga flux

Woyenga aluminiyamu, yemwe amadziwikanso kuti akuyenda, ndi gawo lofunikira kwambiri pakuyenga aluminiyamu.Zimagwira ntchito yofunika kwambiri pakuyeretsa aluminiyamu yosungunuka ndi kuchotsa zonyansa kuti chinthu chomaliza chikhale chapamwamba.

Cholinga chachikulu cha makina oyenga aluminiyamu ndikuthandizira kuchotsa zonyansa zosiyanasiyana zomwe zimapezeka mu aluminiyamu, monga magnesiamu, silicon, ndi zowonongeka zina zazitsulo.Zonyansazi zimatha kusokoneza makina, mawonekedwe, ndi magwiridwe antchito onse a aluminiyumu.

Ma aluminiyamu oyenga zinthu nthawi zambiri amakhala osakaniza mchere ndi fluoride mankhwala.Kusankhidwa kwa mankhwala enieni kumadalira zonyansa zomwe zilipo komanso zotsatira zofunidwa za ndondomeko yoyenga.Zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo cryolite (Na3AlF6), fluorspar (CaF2), alumina (Al2O3), ndi mchere wosiyanasiyana.

Pamene zitsulo zoyenga za aluminiyumu zimalowetsedwa mu aluminiyumu yosungunuka, imapanga wosanjikiza wa slag pamwamba.Slag imakhala ngati chotchinga choteteza pakati pa chitsulo chosungunuka ndi mlengalenga wozungulira.Chotchinga ichi chimakhala ndi zolinga zingapo.Choyamba, imalepheretsa aluminium kuti isakhumane ndi okosijeni, motero amachepetsa mwayi wa okosijeni.Kuonjezera apo, slag layer imalimbikitsa kulekanitsa zonyansa kuchokera ku aluminiyamu yosungunuka, kuwalola kuti achotsedwe mosavuta.

Njira yoyenga imaphatikizapo kuwongolera mosamala kutentha ndi kapangidwe ka aluminiyamu yosungunuka kuti akwaniritse bwino ntchito yoyenga aluminiyamu.Pamene zonyansazo zimagwira ntchito ndi flux, zimapanga mankhwala omwe ali ndi malo osungunuka kwambiri kuposa osungunuka.aluminiyamu.Chotsatira chake, mankhwalawa amamira pansi pa crucible kapena kuyandama pamwamba ngati phulusa, zomwe zimapangitsa kuti zikhale zosavuta kuzilekanitsa ndi aluminiyumu yoyeretsedwa.

Kuchuluka kwa aluminiyamu yoyenga yomwe ikufunika kumadalira zinthu zosiyanasiyana, monga kapangidwe kake ndi kuchuluka kwa zonyansa, mulingo wofunikira wa chiyero, ndi njira yoyenga yomwe imagwiritsidwa ntchito.Ndikofunikira kulinganiza pakati pa kugwiritsa ntchito kuchuluka kokwanira kuti muyeretsedwe moyenera ndikuchepetsa mtengo.

Kugwiritsa ntchito bwino kwa choyenga cha aluminiyumu kumapangitsa kuti aluminiyumu yoyeretsedwa yokhala ndi zida zamakina owonjezera, kutha bwino kwa pamwamba, ndikuchepetsa kufooka kwazovuta.Aluminiyamu yoyengedwayo imatha kugwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikiza magalimoto, ndege, zomangamanga, zopaka, ndi zamagetsi.

Mwachidule, woyenga aluminiyamu ndi gawo lofunika kwambiri pakuyenga aluminiyamu.Zimathandizira kuchotsa zonyansa, zimawonjezera ubwino wa chinthu chomaliza, ndikuwonetsetsa kuti aluminiyumu ikugwirizana ndi zofunikira zomwe zimagwiritsidwa ntchito.
