Fotokozani mwatsatanetsatane njira yoponyera masitepe a aluminiyamu kwa inu

1. Sankhani kutentha koyenera
Kutentha koyenera koponyera kumakhalanso chinthu chofunikira kuti apange khalidwe lapamwambazitsulo za aluminiyamu. Zowonongeka zopangira monga tirigu wouma ndi nthenga za crystal ndizosavuta kuchitika kutentha kukakhala kokwera.
Pambuyo kuyengedwa kwambewu, kutentha kwamadzi 6063 aluminium aloyi kumatha kukulitsidwa moyenera, nthawi zambiri pakati pa 720-740 ℃, chifukwa:
(1) Aluminiyamu yamadzimadzi imakhala yomata pambuyo pakuyengedwa kwambewu ndi kulimba kwachitsulo kosavuta. (2) Pali zone yamadzi-olimba ya magawo awiri kwambiri kutsogolo kwa zitsulo zotayidwa popanga. Kutentha kwapamwamba kwambiri kumakhala ndi malo opapatiza kwambiri, omwe amathandiza kuti mpweya utuluke popanda kutsogolo kwa crystallization. Inde, kutentha sikungakhale kokwera kwambiri, kutentha kwapamwamba kwambiri kumachepetsera nthawi yothandiza ya oyenga tirigu ndikupangitsa njere kukhala yaikulu.
2. Pamene zinthu zilipo, preheat kwathunthu, zimitsani dongosolo kuponyera monga flow tank ndi shunt mbale kuteteza mmene madzi ndi aluminiyamu madzi kupanga mayamwidwe haidrojeni.
3. Mu zotayidwa kapamwamba forging, yesetsani kupewa chipwirikiti ndi anagubuduza za zotayidwa madzi, musamangogwiritsa ntchito zipangizo kusonkhezera zotayidwa madzi mu thanki otaya ndi shunt mbale, kuti zotayidwa madzi pamwamba pa filimu okusayidi pansi pa chitetezo cha khola otaya mu crystallization crystallization.
Ichi ndi chifukwa zida mukubwadamuka madzi zotayidwa ndi madzi otaya anagubuduza zonse kupanga pamwamba zotayidwa okusayidi filimu kugawanika, kupanga makutidwe ndi okosijeni watsopano, pa nthawi yomweyo, ndi okusayidi filimu nawo zotayidwa madzi.
Kafukufukuyu akuwonetsa kuti filimu ya okusayidi imakhala ndi mphamvu zokopa, imakhala ndi madzi 2%, pamene filimu ya oxide imakhudzidwa ndi aluminiyamu yamadzimadzi, madzi mufilimu ya oxide ndi aluminium yamadzimadzimadzi, kupanga mayamwidwe a hydrogen ndi slag.
4. Aluminiyamu bar aluminiyamu madzi kusefera, kusefera ndi njira zothandiza kuchotsa nonmetal slag mu aluminum madzi, mu kupanga 6063 zotayidwa aloyi, kawirikawiri ndi Mipikisano wosanjikiza magalasi CHIKWANGWANI nsalu kusefera kapena ceramic fyuluta mbale kusefera, ziribe kanthu mtundu wa njira kusefera ntchito.
Pofuna kuonetsetsa kusefera yachibadwa a aluminiyamu madzi, zotayidwa madzi ayenera kuchotsedwa pamwamba scum pamaso kusefera, chifukwa pamwamba scum n'zosavuta kupanikizana mauna fyuluta ya zopangira, kuti kusefera sungakhoze kuchitidwa bwinobwino, njira yosavuta kuchotsa pamwamba zinyalala za zotayidwa zamadzimadzi ndi sintha mbale slag mu zitsulo zotayidwa scum, kotero kuchotsedwa scum madzi otaya.
