1. Kuyini i-metallurgicalukuphonswa kwe-vacuum okuqhubekayo?

Ukuphonswa kwe-vacuum okuqhubekayo kwe-Metallurgical kuyindlela entsha yokuphonswa encibilikisa insimbi ngaphansi kwezimo ze-vacuum bese iyifaka esikhumbeni ukuze ikhiqize imikhiqizo yensimbi ngokupholisa nokuqinisa isikhunta. Ukuphonswa kwe-vacuum okuqhubekayo kunezinzuzo kunezindlela zendabuko ezifana nokusebenza kahle okuphezulu, ukunemba okuphezulu, kanye nokusetshenziswa kwamandla aphansi.

2. Imishini evame ukusetshenziswa ekubunjweni kwe-vacuum

Imishini evame ukusetshenziswa kakhulu yokukhipha i-vacuum ihlanganisa kakhulu ama-vacuum furnaces, imishini yokukhipha i-vacuum, isikhunta sokukhipha, njll. Phakathi kwazo, i-vacuum furnace iyithuluzi elibalulekile elidingekayo ekulungiseleleni ama-castings asezingeni eliphezulu, anganikeza indawo eqinile ye-vacuum ukuqinisekisa ikhwalithi nokusebenza kwama-castings.

3. Inqubo kanye nenqubo

Ubuchwepheshe kanye nenqubo yokuphonswa kwe-vacuum okuqhubekayo kuyinkimbinkimbi kakhulu, kudinga izinyathelo eziningi njengokushisa kusengaphambili, ukwelashwa kwe-vacuum, ukuncibilikisa, ukuthulula, ukuqina, njll. Phakathi kwazo, ukwelashwa kwe-vacuum inqubo eyinhloko yokuphonswa kwe-vacuum okuqhubekayo kwe-metallurgical, okungasusa ngempumelelo amagesi nokungcola ensimbi, kuqinisekiswe ikhwalithi kanye nokushelela kobuso bophonswa.

4. Izixazululo zezinkinga ezivamile

Enkambisweni yokukhipha i-vacuum okuqhubekayo ku-metallurgy, izinkinga ezivamile zifaka phakathi ukushisa ngokweqile kwe-crystallizer, ukuchaphaza kwensimbi, ukukhishwa kwegesi okungekuhle, kanye nokuvuleka. Izindlela zokuxazulula lezi zinkinga zifaka phakathi ukwenza ngcono ukwakheka kwe-crystallizer, ukulungisa uhlelo lokushisa, kanye nokuthuthukisa inqubo yokuthulula.

5, Isifinyezo

Ukusetshenziswa kobuchwepheshe bokuphonsa i-vacuum obuqhubekayo be-metallurgical akugcini nje ngokuthuthukisa ikhwalithi kanye nokusebenza kwe-castings, kodwa futhi kuthuthukisa ukusebenza kahle kokukhiqiza futhi konga amandla. Ngokuthuthuka okuqhubekayo komkhakha wokukhiqiza, ukuphonsa i-vacuum okuqhubekayo kwe-metallurgical kuzosetshenziswa kabanzi futhi kube ubuchwepheshe obubalulekile embonini yokusakaza yesikhathi esizayo.

Yiziphi izinzuzo kanye nokungalungi kokukhipha i-vacuum?

Ukuphonswa kwe-vacuum kuyinqubo yokuphonswa endaweni engenawo umoya, enezinzuzo nezinselele ezithile uma kuqhathaniswa nezindlela zokuphonswa zendabuko. Nazi ezinye izinzuzo nezimbi zokuphonswa kwe-vacuum:

Izinzuzo:

Imikhiqizo esezingeni eliphezulu: Indawo yokuhlanza inganciphisa ngempumelelo ukuxhumana phakathi kwezinsimbi namagesi afana nomoya-mpilo ne-nitrogen emoyeni, ngaleyo ndlela kuncishiswe ukungcoliswa komoya kanye nokunye ukungcola, okusiza ekukhiqizeni imikhiqizo yensimbi ne-alloy esezingeni eliphezulu nehlanzekile kakhulu.

Ukulawula ukunemba: Ngesikhathi senqubo yokuphonswa kwe-vacuum, izici ezifana nokushisa, ingcindezi, kanye nomoya zingalawulwa ngokunembe kakhudlwana, okwenza ukwakheka kanye nezakhiwo zomkhiqizo kufane futhi kuhambisane, ngaleyo ndlela kuthuthukiswe ukunemba komkhiqizo.

Ukunciphisa ukuvuleka kanye nokufakwa: Ngenxa yokuqukethwe okuphansi kwegesi endaweni yokuhlanza, kusiza ukunciphisa ukuvuleka kanye nokufakwa ekubunjweni, kuthuthukise ukufana kanye nobuningi bomkhiqizo.

Ifanelekela ama-alloy anezinga lokuncibilika eliphezulu: Ukuphonswa kwe-vacuum kufanelekile ekuphonsweni kwezinsimbi nama-alloy anezinga lokuncibilika eliphezulu ngoba endaweni engenazinga lokuncibilika, izinga lokuncibilika lalezi zinto liyancishiswa, okusiza ukulawula kangcono inqubo yokuphonswa.

Ukuvikelwa kwemvelo: Inqubo yokukhipha i-vacuum inciphisa ukukhiqizwa kwegesi kanye nemfucuza eqinile, okwenza kube nobungane kakhulu nemvelo.

Okubi:

Izindleko zemishini eziphezulu: Imishini yokukhipha i-vacuum ivame ukubiza kakhulu ngoba idinga umklamo okhethekile kanye nezinhlelo zokulawula ezinembile kakhulu.

Ukugcinwa okuyinkimbinkimbi: Ukugcinwa nokusebenza kwemishini yokuhlanza kuyinkimbinkimbi kakhulu, kudinga ulwazi namakhono ochwepheshe.

Ukusebenza kahle kokukhiqiza okuphansi kakhulu: Uma kuqhathaniswa nezinye izindlela zokusakaza zendabuko, ukusakaza nge-vacuum kungaba nokusebenza kahle kokukhiqiza okuphansi, ikakhulukazi ekukhiqizeni okukhulu.

Ububanzi bokusetshenziswa okulinganiselwe: Ukuphonswa kwe-vacuum kusetshenziswa kakhulu emikhakheni edinga ikhwalithi ephezulu kakhulu yomkhiqizo kanye nezinsimbi ezihlanzekile kakhulu, ezingase zibonakale ziyinkimbinkimbi kakhulu futhi zibiza kakhulu ekusetshenzisweni okuvamile.

Sekukonke, ukukhishwa kwe-vacuum kuwubuchwepheshe obuthuthukisiwe obufanele izindawo ezithile zokusetshenziswa, futhi ukuhweba phakathi kwezinzuzo nokungalungi kuncike ezidingweni ezithile zokukhiqiza kanye nezidingo.

Umshini wokuphonsa oqhubekayo we-vacuum we-Hasung uzohlangabezana nesidingo sama-alloy asezingeni eliphezulu ezimbonini ezahlukahlukene.
