Ubwino Wantchito wa Cast Copper Alloys

1. Makhalidwe a ndondomeko: Ambirizitsulo zamkuwakukhala ndi shrinkage yaikulu, kuti ndondomeko yolimba iyenera kuyendetsedwa panthawi yoponya kuti asiye kupanga mapangidwe a shrinkage cavities.Tin bronze ndi okosijeni bwino mkati mwamadzimadzi, kuti kutuluka kwake kusasokonezedwe pakuthira.Pa nthawi yofanana, ndondomeko yothira iyenera kukhala yokonzeka kuteteza chitsulo chosungunuka kuti chisagwedezeke, kuti chitsulo chosungunuka chiziyenda bwino.Njira yothirira pansi imagwiritsidwa ntchito popanga.Tin bronze Z ndi yoyenera kuponya nkhungu yachitsulo, chifukwa kuzizira kwa nkhungu yachitsulo kumathamanga, komwe kumachepetsa malo olimba achitsulo chosungunula, ndipo sikophweka kupereka shrinkage porosity, komanso mawonekedwe a mkati mwa kuponyera. wandiweyani.
2. The smelted steel alloy of cast copper alloy ndithudi imakhala ndi oxidized mkati mwa madzi amadzimadzi, choncho oxide yomwe imapangidwa imasungunuka mkati mwa mkuwa kuti iwononge makina a alloy.Monga ma aloyi a aluminiyamu, ma aloyi amkuwa nthawi zambiri amasungunuka mung'anjo yowotcha kwambiri, kuti madzi amkuwa asakhudze mafuta ndi mpweya, motero kuchepetsa makutidwe ndi okosijeni ndi kutayika kwachitsulo ndikusunga chitsulo choyera.Pofuna kuletsa okosijeni wa mkuwa, zotuluka ngati galasi ndi borax ziyenera kuwonjezeredwa kubisa madzi amkuwa akasungunula mkuwa.Popeza zinki mu mkuwa wokha ukhoza kukhala deoxidizer wabwino, palibe kuyenera kuwonjezera flux ndi deoxidizer pamene kusungunula mkuwa.
3. Gulu: Amagawidwa m'magulu awiri: mkuwa wonyezimira ndi mkuwa;kuponyedwa mkuwa kumagawidwanso mkuwa wamba ndi mkuwa wapadera;mkuwa woponyedwa umagawidwanso kukhala malata amkuwa ndi aloyi yapadera yamkuwa.Copper alloy ndi aloyi yomwe imapangidwa powonjezera chimodzi kapena zinthu zina zingapo zamkuwa wangwiro chifukwa matrix.Mkuwa woyera ndi wofiirira-wofiira, womwe umatchedwanso mkuwa.Kachulukidwe ka mkuwa koyera ndi 8.96, malo oziziritsa ndi 1083 ℃, ndipo ndiyabwino kwambiri madutsidwe amagetsi, matenthedwe amafuta, ductility ndi kukana dzimbiri.
4. Amazolowera kwambiri kupanga zida zamagetsi monga ma jenereta, mabasi, zingwe, switchgear, thiransifoma, ndi zina zambiri, kuphatikiza ngati zida zopangira kutentha monga zosinthira kutentha, mapaipi, zotolera zalathyathyathya za zida zotenthetsera dzuwa.Ma aloyi amkuwa omwe amagwiritsidwa ntchito nthawi zambiri amagawidwa m'magulu atatu: mkuwa, mkuwa ndi cupronickel.Mkuwa ukhoza kukhala aloyi yamkuwa yokhala ndi zinki chifukwa chowonjezera chachikulu, chomwe chimaphatikizapo mtundu wokongola wachikasu ndipo chimawonedwa pamodzi ngati mkuwa.Copper-zinc binary alloy amatchedwa mkuwa wamba kapena mkuwa wosavuta.Brass yokhala ndi ma yuan atatu imatchedwa mkuwa wapadera kapena mkuwa wovuta.Ma aloyi amkuwa okhala ndi zinc 36% amapangidwa ndi yankho lolimba komanso amakhala ndi ntchito yabwino yozizira.mwachitsanzo, mkuwa wokhala ndi 30% zinki nthawi zambiri umapanga zipolopolo za zipolopolo, zomwe zimatchedwa bullet casing brass kapena seven-three brass.
