Uburyo bwo Guhumura Umuringa woroshye

Guhitamo ibikoresho
Uburyohe bwibikoresho bigomba gutera imbere hamwe nuburyohe bwaumuringaUbwoko.Iyo gushonga umuringa utari ngombwa, niba ubwiza bwamafaranga bwizewe, rimwe na rimwe gukoresha ibikoresho bishaje bishobora kugera 100%.Nyamara, kugirango hamenyekane ubwiza bwashonga kandi bigabanye igihombo cyaka, imikoreshereze yumuriro ugabanijwe neza nkibishishwa bitandukanye cyangwa imitobe ya zinc ntigomba kurenza 30%.Ubuso bw'igeragezwa: Iyo ukoresheje 50% ya cathode y'umuringa hamwe na 50% bikozwe mu muringa, igihe gikenewe cyo gushonga nicyo kirekire kandi gukoresha ingufu ni byinshi.Niba ingunguru ya zinc yashyutswe kugeza 100 ~ 150 ℃ ikagaburirwa mubice, nibyiza cyane ko irohama kandi igashonga muri pisine yashongeshejwe vuba, bishobora kugabanya igihombo cyaka cyuma.Ongeramo umubare muto wa fosifore urashobora gukora firime ya oxyde ya elastike igizwe na 2ZnO.p2o2 hejuru yicyuzi gishongeshejwe.Wongeyeho umubare muto wa aluminium, nka 0.1% ~ 0.2%, urashobora gukora firime ikingira Al2O3 hejuru yikidendezi cyashongeshejwe, kandi igafasha kwirinda no kugabanya ihindagurika rya zinc no kunoza imiterere ya casting.Iyo umubare munini wibikoresho bishaje bikoreshwa mu gushonga imiringa, hakwiye gukorwa mbere yindishyi kubintu bimwe na bimwe bifite igihombo kinini.Kurugero, amafaranga yabanjirije indishyi ya zinc ni 0.2% mugihe ushonga umuringa muto-zinc, amafaranga yabanjirije indishyi ya zinc ni 0.4% -0.7% mugihe umuringa wo hagati wa zinc ushongeshejwe, naho indishyi zabanje kwishyurwa ni 1,2% -2.0% mugihe umuringa wa zinc mwinshi ushonga.
Kugenzura uburyo bwo gushonga
Urutonde rusange rwinyongera mugihe ushonga umuringa ni: umuringa, ibikoresho bishaje na zinc.Iyo gushongesha umuringa mubikoresho byicyuma, umuringa ugomba kubanza gushonga.Mubisanzwe, iyo umuringa ushonga ugashyuha cyane mubushyuhe runaka, ugomba guhumeka neza (urugero na fosifore) hanyuma zinc igomba gushonga.Iyo amafaranga yishyuwe arimo umuringa ushaje, urwego rwo kwishyuza rushobora guhindurwa uko bikwiye ukurikije imiterere nyayo nkibiranga ibice bivangwa nubwoko bwitanura.Kuberako ibikoresho bishaje ubwabyo birimo zinc, kugirango bigabanye igihombo cyo gushonga kwa zinc, ibikoresho bishaje byumuringa bigomba kongerwaho no gushonga birangiye.Nyamara, ibice binini byishyurwa ntibikwiye kwishyurwa rya nyuma no gushonga.Niba amafaranga yatose, ntagomba kongerwaho muburyo bwo gushonga.Niba amafaranga yatose yongeweho hejuru yandi mashanyarazi adashongeshejwe, bizashiraho igihe cyo kumisha no gushyushya mbere yo gushonga, bikaba bidafite akamaro gusa kwirinda guhumeka gushonga, ariko no kwirinda izindi mpanuka.Kwiyongera kwa Zinc ku bushyuhe buke nihame shingiro rigomba gukurikizwa hafi ya yose yo gushonga imiringa.Ongeramo zinc ku bushyuhe buke ntibishobora kugabanya igihombo cya zinc gusa, ariko kandi bifasha umutekano wibikorwa byo gushonga.Iyo gushongesha umuringa mu ziko ryumuriro wa fer-core induction, muri rusange ntabwo ari ngombwa kongeramo deoxidizer kuko gushonga ubwabyo, ni ukuvuga pisine yinzibacyuho, irimo zinc nyinshi.Ariko, mugihe ubwiza bwashonge ari bubi, 0.001% ~ 0.01% fosifore nayo irashobora kongerwaho ukurikije uburemere bwamafaranga yishyurwa rya deoxidation yubufasha.Ongeramo agace gato k'umuringa-fosifore master alloy gushonga birashobora kongera umuvuduko wamazi mbere yuko irekurwa mu itanura.Dufashe umuringa wa H65 nk'urugero, aho ushonga ni 936 ° C.Kugirango gaze nikinyamakuru mu gushonga bireremba kandi bisohore mugihe, bitarinze guhindagurika cyane kwa zinc no guhumeka gushonga, ubushuhe bwo gushonga bugenzurwa kuri 1060 ~ 1100 ° C.Ubushyuhe burashobora kwiyongera muburyo bukwiye kugeza 1080 ~ 1120 ℃.Nyuma yo "gucira umuriro" inshuro 2 kugeza kuri 3, zijugunywa mubihindura.Gupfukirana amakara yatetse mugihe cyo gushonga, kandi ubunini bwurwego rutwikiriye bigomba kuba birenze 80mm.
