1. Metallurgical ndi chiyanikuponya vacuum mosalekeza?

Metallurgical continuous vacuum casting ndi njira yatsopano yoponyera yomwe imasungunula zitsulo pansi pazitsulo zotsekemera ndikuzilowetsa mu nkhungu kupanga zinthu zachitsulo kupyolera mu kuzizira ndi kulimba kwa nkhungu. Kuponyera vacuum mosalekeza kumakhala ndi zabwino kuposa njira zachikhalidwe monga kuchita bwino kwambiri, kulondola kwambiri, komanso kugwiritsa ntchito mphamvu zochepa.

2. Zida zomwe zimagwiritsidwa ntchito kwambiri poponya vacuum

Zida zomwe zimagwiritsidwa ntchito popangira vacuum makamaka zikuphatikizapo ng'anjo za vacuum, makina oponyera vacuum, zitsulo zotayira, etc. Pakati pawo, ng'anjo yowonongeka ndi chida chofunika kwambiri pokonzekera ma castings apamwamba kwambiri, omwe angapereke malo otsetsereka a vacuum kuti atsimikizire khalidwe ndi ntchito za castings.

3. Njira ndi ndondomeko

Ukadaulo ndi ndondomeko ya mosalekeza vakuyumu kuponyera ndi zovuta, amafuna masitepe angapo monga preheating, zingalowe mankhwala, kusungunuka, kuthira, solidification, etc. Pakati pawo, vakuyumu mankhwala ndi pachimake ndondomeko ya metallurgical mosalekeza vakuyumu kuponyera, amene angathe kuchotsa bwino mpweya. ndi zosafunika muzitsulo, kuonetsetsa ubwino ndi kusalala kwa pamwamba pa kuponyera.

4. Njira zothetsera mavuto omwe wamba

Popitirizabe kutulutsa vacuum muzitsulo, mavuto omwe amapezeka nthawi zambiri amaphatikizapo kutenthedwa kwa crystallizer, kuwotcha kwachitsulo, kutulutsa mpweya woipa, ndi porosity. Njira zothetsera mavutowa ndi monga kukhathamiritsa mapangidwe a crystallizer, kusintha makina otenthetsera, komanso kukonza njira yothira.

5, Chidule

Kugwiritsa ntchito ukadaulo wazitsulo wopitilira muyeso wa vacuum sikuti kumangokulitsa luso komanso magwiridwe antchito a castings, komanso kumapangitsa kuti pakhale mphamvu zopanga ndikupulumutsa mphamvu. Ndi chitukuko mosalekeza makampani opanga, metallurgical mosalekeza vakuyumu kuponyera adzakhala ankagwiritsa ntchito ndi kukhala luso lofunika mu makampani akuponya tsogolo.

Kodi ubwino ndi kuipa kwa vacuum casting ndi chiyani?

Kuponyera vacuum ndi njira yoponyera m'malo opanda vacuum, yomwe ili ndi zabwino ndi zovuta zina poyerekeza ndi njira zachikhalidwe zoponya. Nazi zina zabwino ndi kuipa kwa vacuum casting:

Ubwino:

Zogulitsa zapamwamba: Malo opumulira amatha kuchepetsa kukhudzana pakati pa zitsulo ndi mpweya monga mpweya ndi nayitrogeni mumlengalenga, potero amachepetsa makutidwe ndi okosijeni ndi kuipitsidwa kwina, komwe kumathandizira kupanga zitsulo zapamwamba komanso zoyera kwambiri.

Kuwongolera mwatsatanetsatane: Panthawi yoponyera vacuum, zinthu monga kutentha, kupanikizika, ndi mlengalenga zimatha kuyendetsedwa bwino kwambiri, kupanga mapangidwe ndi katundu wa chinthucho kukhala chofanana komanso chosasinthasintha, potero kuwongolera kulondola kwa chinthucho.

Kuchepetsa porosity ndi inclusions: Chifukwa cha kuchepa kwa mpweya m'malo opanda mpweya, zimathandiza kuchepetsa porosity ndi inclusions poponya, kupititsa patsogolo kufanana ndi kachulukidwe ka mankhwala.

Oyenera ma alloys apamwamba osungunuka: Kuponyera kwa vacuum ndikoyenera kuponyera zitsulo zosungunuka kwambiri ndi ma alloys chifukwa m'malo opanda mpweya, malo osungunuka azinthuzi amachepetsedwa, zomwe zimathandiza kuwongolera bwino njira yoponyera.

Kuteteza chilengedwe: Njira yopangira vacuum imachepetsa kutulutsa kwa gasi ndi zinyalala zolimba, zomwe zimapangitsa kuti zisawononge chilengedwe.

Zoyipa:

Mtengo wapamwamba wa zida: Zida zoponyera vacuum nthawi zambiri zimakhala zokwera mtengo chifukwa zimafunikira mapangidwe apadera komanso njira zowongolera zolondola kwambiri.

Kukonza movutikira: Kukonza ndi kugwiritsa ntchito zida za vacuum ndizovuta, zomwe zimafuna chidziwitso ndi luso laukadaulo.

Kuchita bwino pang'ono popanga: Poyerekeza ndi njira zachikhalidwe zoponyera, zotayira zotayira zitha kukhala ndi magwiridwe antchito ocheperako, makamaka pakupanga kwakukulu.

Kuchulukirachulukira kwa ntchito: Kuponyera vacuum kumagwiritsidwa ntchito makamaka m'magawo omwe amafunikira zida zapamwamba kwambiri komanso zitsulo zoyeretsedwa kwambiri, zomwe zitha kuwoneka zovuta komanso zokwera mtengo pazogwiritsidwa ntchito wamba.

Ponseponse, kuponyera vacuum ndiukadaulo wapamwamba woyenerera madera ena ogwiritsira ntchito, ndipo kusinthanitsa pakati pa zabwino ndi zoyipa kumatengera zosowa ndi zofunikira pakupangira.

Hasung vacuum mosalekeza kuponya makina adzakwaniritsa kufunikira kwa ma alloys apamwamba kwambiri m'mafakitale osiyanasiyana.
