Mapaipi Aakulu A Aluminiyamu Amkuwa Osagonjetsedwa ndi Dzimbiri

Chitoliro Chachikulu Cha Aluminiyamu Chamkuwa - Ndondomeko Yotsimikizira Njira & Ubwino

Machubu athu a aluminiyamu akuluakulu okwana mainchesi awiri amapangidwa kuti athe kupirira mikhalidwe yovuta kwambiri m'malo a m'nyanja ndi m'mafakitale, zomwe zimapangitsa kuti zikhale zodalirika kwa nthawi yayitali pomwe zipangizo zochepa sizingagwire ntchito.

Zinthu zazikulu zomwe zimachitika

● Chiŵerengero chachikulu cha extrusion (≥ 30:1) mu gawo la extrusion chimaswa bwino tirigu wouma ngati wothira ndipo chimapeza recrystallization yonse;
● Kujambula kopitilira muyeso pamodzi ndi maulendo awiri owala a vacuum annealing kumachotsa kupsinjika kwamkati ndikuletsa kukhuthala kwapakati pa granular, kusunga ukhondo wapamwamba pamwamba ndi mkati mwa zinthuzo;
● Kulekerera kwa miyeso komwe kumayendetsedwa mkati mwa ± 0.05 mm, kusiyana kwa makulidwe a khoma ≤ 3%, kulunjika ≤ 0.5 mm/m, ndi kusinthasintha kwapamwamba kozungulira kopitilira zofunikira za muyezo wadziko lonse;
● Kuyesa kwa 100% kwa eddy current kowonjezeredwa ndi ultrasound kuwunika kumachotsa ming'alu pamwamba ndi pansi pa nthaka, zinthu zomwe zili mkati mwake, khungu la lalanje, ndi zolakwika zina.

Dongosolo lowongolera khalidwe

Kupanga kumaphatikiza kuponyera kwapamwamba ndi njira zolondola zopangira kuti zikhale zabwino kwambiri pakukula kwakukulu:
●Kusungunula Alloy: Ma ingot ovomerezeka amasungunuka mu uvuni woyendetsedwa bwino, ndipo kapangidwe kake kamawunikidwa nthawi yonse yothira.
●Kuponya Mchenga kapena M'ma Centrifugal: Malo obisika okhuthala amapangidwa pogwiritsa ntchito njira zoyenera kukula kwakukulu, kuonetsetsa kuti palibe ma porosity ambiri.
●Kugwira Ntchito Yotentha: Kutulutsa kapena kuboola kumapanga mawonekedwe a chubu, kuyeretsa tirigu ndikuwongolera mphamvu zamakina.
●Kuchiza Kutentha: Kuphimba kwathunthu kumawonjezera mphamvu ndi kusinthasintha kwa kutentha pamene kumachotsa kupsinjika kwamkati.
●Kukonza ndi Kumaliza: Malo akunja ndi amkati amatembenuzidwa kapena kuphwanyidwa kuti akwaniritse miyeso yolondola komanso kumalizidwa bwino.
●Kuwongola ndi Kuyesa: Machubu amawongoledwa ndipo amayesedwa koyamba asanavomerezedwe komaliza.
●Kuteteza ndi Kuyika Zinthu Pamwamba: Malo ozungulira amatsukidwa ndi kupakidwa mafuta oteteza, kenako amamangiriridwa bwino kuti zinthu zitumizidwe padziko lonse lapansi.
