Mfundo zazikuluzikulu za aluminium bronze semi - njira yopititsira patsogolo

Aluminium bronzeali ndi mphamvu zoponyera za kuyamwa mwamphamvu, kutsekemera kosavuta kwa okosijeni, kutsika kwakukulu kolimba, kusasunthika bwino kwamafuta, komanso kusachita bwino pakuponya. Asanaponye, ​​opanga malata amkuwa adagwiritsa ntchito zosakaniza zazitsulo za alkali padziko lapansi, monga Na₃AlF₆ ndi NaF, monga chothandizira kuyeretsa mkuwa wamadzimadzi. Zinali zothandiza kukonza mawonekedwe a crystalline azitsulo zoyera zamadzimadzi ndi ingot.

Kutentha kwa aluminium bronze nthawi zambiri kumakhala 1120 ~ 1180 ℃, ndipo kutentha kwa ingot yayikulu kumakhala kochepa pang'ono. Pamene aluminiyamu yamkuwa yozungulira ingot iponyedwa, mlingo wamadzimadzi wachitsulo mu nkhungu ukhoza kuponyedwa momasuka popanda chitetezo chilichonse.

Kusungunuka kumalowa mu nkhungu kudzera mu dzenje lomwe lili pansi pa fupalo. Mapangidwe a kabowo ka faniyo ayenera kukumana ndi zinthu ziwiri nthawi imodzi: imodzi ndikuwonetsetsa kuti kuthamanga kwa kuthamanga kumagwirizana ndi liwiro loponya; Chachiwiri, onetsetsani kuti funnel nthawi zonse imakhala ndi mulingo wina wamadzimadzi, kuti zinyalala zamadzimadzi zisathe kulowa mu nkhungu kuchokera ku dzenje. Aluminium-bronze ingot imakonda kukhala porosity ndi shrinkage yokhazikika. M`pofunika mosamala kudzaza kumapeto kuthira kupewa anaikira shrinkage wa ingot.

Waya wa aluminiyamu wamkuwa wokhala ndi kupindana ukhoza kukhala ndi kusakhazikika komanso kusinthasintha. Ngati pali zowunikira zowunikira pamwamba, pamwamba pa waya wamkuwa wawonongeka, zomwe zitha kuchitika pojambula waya, zomwe zikuwonetsa kuti waya wamkuwa si wabwino. Ngati mawaya amkuwa opangidwa ali ndi izi, tiyenera kusamala kuti tiwone ngati nkhungu yathu yatha, komanso ngati gudumu lowongolera silimasinthasintha kwa nthawi yayitali, zomwe zingayambitse mavuto.

Ngati pali zizindikiro zina zomwe zikusowa pamwamba pa waya wamkuwa wa aluminiyumu, mawonekedwe owoneka bwino ndi oipa kwambiri. Chodabwitsa ichi chimatchedwa tsitsi, lomwe limayambitsidwanso ndi kutha, ndipo pali zotupa ndi zovuta zina, zomwe zimasonyeza kuti ubwino wa waya wamkuwa si wabwino kwambiri. Kuchokera ku maonekedwe akhoza kuwonedwa pafupifupi khalidwe la waya wamkuwa, choncho tiyenera kutsegula maso athu pogula waya wamkuwa, kuti tisasokonezedwe ndi zinthu zochepa.
