1. Yini i-metallurgicalukukhishwa kwe-vacuum okuqhubekayo?

I-Metallurgical continuous vacuum casting iwuhlobo olusha lwendlela yokuphonsa encibilikisa insimbi ngaphansi kwezimo ze-vacuum bese iyijova esikhunjeni ukuze kwenziwe imikhiqizo yensimbi ngokupholisa nokuqiniswa kwesikhunta. Ukukhishwa kwe-vacuum okuqhubekayo kunezinzuzo kunezindlela zendabuko ezifana nokusebenza kahle okuphezulu, ukunemba okuphezulu, nokusetshenziswa kwamandla okuphansi.

2. Izisetshenziswa ezivame ukusetshenziswa ku-vacuum casting

Imishini evame ukusetshenziselwa ukukhishwa kwe-vacuum ikakhulukazi ihlanganisa iziko le-vacuum, imishini yokukhipha i-vacuum, isikhunta sokuphonsa, njll. Phakathi kwazo, isithando somlilo siyisisetshenziswa esibalulekile esidingekayo ekulungiseleleni ukukhishwa kwekhwalithi ephezulu, okunganikeza indawo ehlanzekile ye-vacuum ukuze kuqinisekiswe izinga kanye nekhwalithi. ukusebenza kwe-castings.

3. Inqubo kanye nenqubo

Ubuchwepheshe kanye nenqubo yokusakazwa kwe-vacuum okuqhubekayo kuyinkimbinkimbi, kudinga izinyathelo eziningi ezifana nokushisa kwangaphambili, ukwelashwa kwe-vacuum, ukuncibilika, ukuthulula, ukuqinisa, njll. Phakathi kwazo, ukwelashwa kwe-vacuum kuyinqubo eyinhloko ye-metallurgical continuous vacuum casting, engasusa ngokuphumelelayo amagesi. kanye nokungcola kwensimbi, okuqinisekisa ikhwalithi nokushelela kwendawo yokubunjwa.

4. Izixazululo zezinkinga ezivamile

Enqubweni yokukhishwa kwe-vacuum okuqhubekayo ku-metallurgy, izinkinga ezivamile zihlanganisa ukushisa okweqile kwe-crystallizer, ukuchaphazeka kwensimbi, ukukhishwa kwegesi okungekuhle, kanye ne-porosity. Izindlela zokuxazulula lezi zinkinga zihlanganisa ukwenza kahle ukwakheka kwecrystallizer, ukulungisa uhlelo lokushisa, kanye nokwenza ngcono inqubo yokuthulula.

5. Isifinyezo

Ukusetshenziswa kobuchwepheshe be-vacuum casting obuqhubekayo be-metallurgical akuthuthukisi nje kuphela ikhwalithi nokusebenza kokusakazwa, kodwa futhi kuthuthukisa ukusebenza kahle kokukhiqiza futhi konga amandla. Ngokuthuthuka okuqhubekayo kwemboni yokukhiqiza, i-metallurgical vacuum casting eqhubekayo izosetshenziswa kabanzi futhi ibe ubuchwepheshe obubalulekile embonini yokuphonsa yesikhathi esizayo.

Yiziphi izinzuzo kanye nokubi kwe-vacuum casting?

Ukukhipha i-vacuum kuyinqubo yokuphonsa endaweni engenalutho, enezinzuzo nezinselele ezithile uma kuqhathaniswa nezindlela zokusakaza zendabuko. Nazi ezinye izinzuzo kanye nokubi kokusakazwa kwe-vacuum:

Izinzuzo:

Imikhiqizo yekhwalithi ephezulu: Imvelo ye-vacuum inganciphisa ngempumelelo ukuthintana phakathi kwezinsimbi namagesi afana ne-oxygen ne-nitrogen emoyeni, ngaleyo ndlela kuncishiswe i-oxidation nokunye ukungcola, okusiza ukukhiqiza imikhiqizo yensimbi ne-alloy esezingeni eliphezulu futhi ehlanzekile kakhulu.

Ukulawula okunembayo: Phakathi nenqubo yokukhipha i-vacuum, izici ezifana nezinga lokushisa, ingcindezi, nomoya kungalawuleka ngokunembe kakhudlwana, kwenze ukwakheka nezakhiwo zomkhiqizo zifane futhi zingaguquguquki, ngaleyo ndlela kuthuthukiswe ukunemba komkhiqizo.

Ukunciphisa i-porosity ne-inclusions: Ngenxa yokuqukethwe kwegesi ephansi endaweni ye-vacuum, kusiza ukunciphisa i-porosity kanye nokufaka ekusakazeni, ukuthuthukisa ukufana nokushuba komkhiqizo.

Ifanele ama-alloys amaphuzu aphezulu okuncibilika: I-vacuum casting ifanele ukuphonswa kwezinsimbi eziphezulu zokuncibilika kanye nama-alloys ngoba endaweni ye-vacuum, indawo yokuncibilika yalezi zinto iyancishiswa, okusiza ukulawula kangcono inqubo yokukhipha.

Ukuvikelwa kwemvelo: Inqubo yokukhipha i-vacuum inciphisa ukukhiqizwa kwegesi kanye nemfucuza eqinile, ikwenze kube nobungane ngokwemvelo.

Ububi:

Izindleko eziphezulu zemishini: Imishini yokukhipha ivacuum ngokuvamile ibiza kakhulu ngoba idinga ukwakheka okukhethekile kanye nezinhlelo zokulawula ezinembe kakhulu.

Ukulungiswa okuyinkimbinkimbi: Ukugcinwa nokusebenza kwemishini yevacuum kuyinkimbinkimbi, kudinga ulwazi lochwepheshe kanye namakhono.

Ukusebenza kahle kokukhiqiza okuphansi uma kuqhathaniswa: Uma kuqhathaniswa nezindlela ezithile zokulingisa ezivamile, ukukhishwa kwe-vacuum kungase kube nokusebenza kahle kokukhiqiza okuphansi, ikakhulukazi ekukhiqizeni ngezinga elikhulu.

Ububanzi bokusebenza obunomkhawulo: I-vacuum casting isetshenziswa kakhulu emikhakheni edinga ikhwalithi yomkhiqizo ephezulu kakhulu nezinsimbi ezihlanzeke kakhulu, ezingase zibonakale ziyinkimbinkimbi kakhulu futhi zibiza kakhulu ezisetshenziswayo ezijwayelekile.

Sekukonke, i-vacuum casting ubuchwepheshe obuthuthukisiwe obufanele izindawo ezithile zokufaka izicelo, futhi ukuhwebelana phakathi kwezinzuzo nokubi kuncike ezidingweni ezithile zokukhiqiza kanye nezidingo.

Umshini wokukhipha i-hasung vacuum oqhubekayo uzohlangabezana nesidingo sama-alloys ekhwalithi ephezulu ezimbonini ezahlukahlukene.
