Izindaba

Umshini Ovundlile Wokuphonsa Oqhubekayo(HVCCM) iyithuluzi elinembile elisetshenziswa embonini yensimbi ukukhiqiza imikhiqizo yensimbi esezingeni eliphezulu. Lobu buchwepheshe bushintshe indlela okubunjwa ngayo insimbi futhi bunikeza izinzuzo eziningi kunezindlela zokudala zokukhipha. Kulesi sihloko, sizoxoxa ngezimiso zenqubo, izingxenye kanye nokusetshenziswa kwama-casters aqhubekayo e-vacuum avundlile.

Funda ngokusakaza okuqhubekayo kwe-vacuum okuvundlile

Ngaphambi kokuhlola izimiso zenqubo, kubalulekile ukuqonda ukuthi kusho ukuthini ukuphonswa okuqhubekayo kwe-vacuum okuvundlile. Le ndlela ihilela ukuphonswa okuqhubekayo kwensimbi encibilikisiwe ibe yifomu eqinile ngenkathi kugcinwa indawo ye-vacuum. Umgomo oyinhloko ukukhiqiza imikhiqizo yensimbi ehlanzekile kakhulu eneziphambeko ezincane, okubaluleke kakhulu ezimbonini ezifana nezindiza, izimoto kanye ne-elekthronikhi.

Izingxenye ezibalulekile ze-HVCCM

Isithando somlilo: Inqubo iqala ngesithando somlilo lapho izinto zokusetshenziswa zishiswa khona zize zincibilike. Isithando somlilo sivame ukuhlonyiswa ngokushisa kokufakelwa noma ubuchwepheshe be-arc kagesi ukuqinisekisa ukushisa okufanayo.

Isithando Sokushisa: Ngemva kokuncibilika, insimbi encibilikisiwe idluliselwa esithandweni somlilo esibambayo. Isithando sigcina izinga lokushisa lensimbi encibilikisiwe futhi siqinisekise ukuthi ihlala imanzi kuze kube yilapho isilungele ukuphonswa.

Ukuphonsa Isikhunta: Isikhunta sokubumba siyisici esibalulekile se-HVCCM. Senzelwe ukunikeza insimbi encibilikisiwe ukuma njengoba iqina. Isikhunta ngokuvamile senziwe ngezinto ezisezingeni eliphezulu ezingamelana namazinga okushisa aphezulu kanye nokucindezeleka.

Igumbi Lokuhlanza I-Vacuum: Igumbi lokuhlanza yilapho kwenzeka khona ukuphonswa kwangempela. Ngokudala indawo yokuhlanza, umshini unciphisa ukuba khona kwamagesi nokungcola okungabangela amaphutha kumkhiqizo wokugcina.

Uhlelo Lokupholisa: Uma insimbi encibilikisiwe isithelwe esikhumbeni, iqala ukuphola futhi iqine. Uhlelo lokupholisa luqinisekisa ukuthi insimbi iphola ngokulinganayo, ivimbele ukuguguleka noma ukuqhekeka.

Imishini yokusika nokuqeda: Ngemva kokuqina, umkhiqizo oqhubekayo unqunywa ubude obudingekayo bese ufakwa enkambisweni yokuqeda ukuze kufezwe ikhwalithi edingekayo ebusweni.

Isimiso senqubo ye-HVCCM

Isimiso senqubo yomshini wokuphonsa oqhubekayo we-vacuum ovundlile ungahlukaniswa ngezigaba eziningana ezibalulekile:

1. Ukuncibilikisa Nokugquma

Inqubo iqala ngokuncibilika kwezinto zokusetshenziswa esithandweni somlilo. Isithando somlilo senzelwe ukufinyelela amazinga okushisa aphezulu ngokushesha nangendlela ephumelelayo. Uma insimbi isincibilikile, idluliselwa esithandweni somlilo lapho igcinwa khona ekushiseni okufanayo. Lesi sigaba sibalulekile njengoba siqinisekisa ukuthi insimbi encibilikisiwe iyafana futhi ayinazo izinto ezingcolile.

2. Ukwakhiwa kwe-vacuum

Ngaphambi kokuba inqubo yokubumba iqale, kwakheka i-vacuum ekamelweni lokubumba. Lokhu kufezwa ngokusebenzisa iphampu ye-vacuum ukususa umoya namanye amagesi ekamelweni. Indawo ye-vacuum ibalulekile ukuvimbela i-oxidation kanye nokungcola kwensimbi encibilikisiwe, okungaholela ezifweni kumkhiqizo wokugcina.

3. Ukuthulula insimbi encibilikisiwe

Uma i-vacuum isimisiwe, insimbi encibilikisiwe ithululelwa esikhumbeni. Ukwakheka kwesikhumbeni kuvumela ukugeleza okuqhubekayo kwensimbi okuyisici senqubo ye-HVCCM. Kuyaqashelwa ngesikhathi senqubo yokuthulula ukuqinisekisa ukuthi insimbi igcwalisa isikhumbeni ngokulinganayo futhi akukho ukuxokozela okungangenisa amabhamuza omoya.

4. Ukuqina

Njengoba insimbi encibilikisiwe igcwalisa isikhunta, iqala ukuphola nokuqina. Inqubo yokupholisa ilawulwa ngokucophelela ukuqinisekisa ukuqina okufanayo. Indawo yokuhlanza idlala indima ebalulekile lapha njengoba isiza ukugcina izinga lokushisa elihlala njalo futhi ivimbela ukwakheka kwama-bubbles.

5. Ukukhipha imali njalo

Esinye sezici ezihlukanisayo ze-HVCCM ukususwa okuqhubekayo kwensimbi eqinile kusuka ku-mold. Njengoba insimbi iqina, idonswa kancane kancane kusuka ku-mold ngesivinini esilawulwayo. Le nqubo eqhubekayo ikhiqiza ubude obude bemikhiqizo yensimbi enganqunywa ngosayizi.

6. Ukusika nokuqeda

Uma ubude bensimbi obudingekayo sebukhishwe, buyasikwa kusetshenziswa imishini yokusika ekhethekile. Izinqubo zokuqeda zingafaka phakathi ukwelashwa kwendawo, imishini noma ezinye izindlela zokufeza imininingwane edingekayo. Umkhiqizo wokugcina ube usuhlolwa ikhwalithi kanye nokungaguquguquki.

Izinzuzo zokusakaza okuqhubekayo kwe-vacuum okuvundlile

Umshini wokuphonsa oqhubekayo we-vacuum ovundlile unezinzuzo ezilandelayo uma kuqhathaniswa nezindlela zokuphonsa zendabuko:

Ukuhlanzeka Okuphezulu: Indawo yokuhlanza inciphisa ukuba khona kwamagesi nokungcola, okuholela emikhiqizweni yensimbi emsulwa kakhulu.

Amaphutha Ancishisiwe: Inqubo yokupholisa nokuqinisa elawulwayo inciphisa amathuba okuba neziphambeko ezifana nama-pores kanye nokufakwa.

Ukukhiqizwa Okuqhubekayo: Iukuphonsa okuqhubekayoinqubo ingakhiqiza izinsimbi ezinde ngempumelelo, inciphise imfucuza futhi ikhulise umkhiqizo.

UKUSEBENZISA IZINTO EZININGI: I-HVCCM ingasetshenziswa ezinhlobonhlobo zezinsimbi, okuhlanganisa i-aluminium, ithusi kanye ne-alloys ekhethekile, okwenza kube ukukhetha okuguquguqukayo kwabakhiqizi.

Ukusebenza Kahle Kwezindleko: Nakuba ukutshalwa kwezimali kokuqala kubuchwepheshe be-HVCCM kungaba phezulu, ukonga kwesikhathi eside ezindleleni zezinto ezibonakalayo kanye nokuthuthukiswa kokusebenza kahle kokukhiqiza kuvame ukwedlula lezi zindleko.

Ukusetshenziswa kwe-HVCCM

Okuvundlileimishini yokuphonsa eqhubekayo ye-vacuumzisetshenziswa kabanzi ezimbonini ezahlukene, okuhlanganisa:

Izindiza: Izinsimbi ezihlanzekile kakhulu zibalulekile ezingxenyeni zezindiza lapho ukusebenza nokuthembeka kubalulekile khona.

Izimoto: Imboni yezimoto idinga imikhiqizo yensimbi esezingeni eliphezulu ukuze ikhiqize izingxenye zenjini, izingxenye zokudlulisa kanye nezakhi zesakhiwo.

AMA-ELEKTRONIKI: Imboni ye-elekthronikhi ithembele ezinsimbini ezihlanzekile kakhulu ukwenza amabhodi wesekethe, izixhumi nezinye izingxenye.

Amadivayisi Ezokwelapha: Insimu yezokwelapha idinga izinto ezihlangabezana nezindinganiso zekhwalithi eziqinile, okwenza i-HVCCM ibe yindawo ekahle yokukhiqizwa kwezingxenye zedivayisi yezokwelapha.

Ekuphetheni

Ama-caster aqhubekayo e-vacuum avundlile amelela intuthuko enkulu kubuchwepheshe bokubumba insimbi. Ngokuqonda izimiso zenqubo kanye nezingxenye ezahlukahlukene ezihilelekile, abakhiqizi bangasebenzisa lobu buchwepheshe ukukhiqiza imikhiqizo yensimbi esezingeni eliphezulu eneziphambeko ezincane. Njengoba izimboni ziqhubeka nokufuna ubumsulwa obuphezulu kanye nokusebenza okuvela ezintweni zokwakha, i-HVCCM izodlala indima ebaluleke kakhulu ekuhlangabezaneni nalezi zidingo. Ngezinzuzo zazo eziningi kanye nobubanzi bezicelo, ama-caster avundlile avundlile azoqhubeka nokuba yitshe lesisekelo le-metallurgy yesimanje.
