Ngophuhliso oluqhubekayo lweshishini lokuvelisa, i-metallurgical vacuum casting eqhubekayo iya kusetyenziswa ngokubanzi kwaye ibe yitekhnoloji ebalulekileyo kwishishini lokuphosa elizayo.

Zeziphi izinto eziluncedo kunye nezingeloncedo zokuphosa ivacuum?

I-vacuum casting yinkqubo yokuphosa kwindawo ye-vacuum, enenzuzo kunye nemingeni ethile xa kuthelekiswa neendlela zokuphosa zendabuko. Nazi ezinye iingenelo kunye nobubi bokuphosa ivacuum:

Izinto eziluncedo:

Iimveliso ezikumgangatho ophezulu: Imeko ye-vacuum inokunciphisa ngokufanelekileyo uqhagamshelwano phakathi kwesinyithi kunye neegesi ezifana ne-oksijini kunye ne-nitrogen emoyeni, ngaloo ndlela kuncitshiswa i-oxidation kunye nolunye ungcoliseko, okunceda ukuvelisa umgangatho ophezulu kunye nococeko oluphezulu lwesinyithi kunye neemveliso ze-alloy.

Ukulawulwa ngokuchanekileyo: Ngexesha lenkqubo yokukhupha i-vacuum, izinto ezifana nokushisa, uxinzelelo, kunye nomoya unokulawulwa ngokuchanekileyo, ukwenza ukubunjwa kunye neempawu zemveliso zifanayo kwaye zihambelana, ngaloo ndlela ziphucula ukuchaneka kwemveliso.

Ukunciphisa i-porosity kunye ne-inclusions: Ngenxa yomgangatho ophantsi wegesi kwindawo ye-vacuum, inceda ukunciphisa i-porosity kunye ne-inclusions kwi-casting, ukuphucula ukufana kunye nobuninzi bemveliso.

Ifanelekile kwi-alloys ephezulu ye-melting point: I-vacuum casting ifanelekile ukuchithwa kwezinto eziphezulu zetsimbi kunye ne-alloys ngenxa yokuba kwindawo yokucoca, indawo yokuncibilika kwezi zinto iyancitshiswa, enceda ukulawula kakuhle inkqubo yokuphosa.

Ukhuseleko lokusingqongileyo: Inkqubo yokukhupha ivacuum inciphisa ukuveliswa kwerhasi kunye nenkunkuma eqinileyo, nto leyo eyenza ukuba kulunge ngakumbi ukusingqongileyo.

Izinto ezingeloncedo:

Iindleko eziphezulu zezixhobo: Izixhobo zokugalela ivacuum zidla ngokubiza kakhulu kuba zifuna uyilo olulodwa kunye neenkqubo zolawulo ezichane kakhulu.

Ulondolozo oluntsonkothileyo: Ukugcinwa kunye nokusebenza kwezixhobo zokufunxa kunzima, kufuna ulwazi lobungcali kunye nezakhono.

Ukusebenza kwemveliso ephantsi ngokwentelekiso: Xa kuthelekiswa nezinye iindlela zokugalela zemveli, ukugalelwa kwevacuum kunokuba nemveliso esezantsi esebenzayo, ngakumbi kwimveliso enkulu.

Umda wosetyenziso olulinganiselweyo: Ukufakwa kwevacuum kusetyenziswa ikakhulu kwiindawo ezifuna umgangatho wemveliso ophezulu kakhulu kunye neentsimbi ezisulungekileyo, ezinokubonakala zintsokothile kwaye zibiza kakhulu kwizicelo jikelele.

Ngokubanzi, i-vacuum casting iteknoloji ephakamileyo efanelekileyo kwiindawo ezithile zesicelo, kwaye ukurhweba phakathi kweenzuzo kunye nokungalunganga kuxhomekeke kwiimfuno ezithile zokuvelisa kunye neemfuno.

I-Hasung vacuum eqhubekayo yomatshini wokuphosa uya kuhlangabezana nemfuno yee-alloys ezikumgangatho ophezulu kumashishini ahlukeneyo.
