Ibhodwe elihle kakhulu lokuncibilika 99 95 lokubumba i-tungsten crucible yesithando somlilo esishisayo
Indlela yokukhiqiza ye-tungsten crucible ngokuvamile ihlanganisa izinyathelo ezimbalwa:
Ukukhethwa kwempahla eluhlaza: I-crucible ikhiqizwa kusetshenziswa impahla ye-tungsten yekhwalithi ephezulu enobumsulwa obungu-99.95%.Ukuhlanzeka kwezinto kubalulekile ukuze kuqinisekiswe ukuthi i-crucible ingakwazi ukumelana namazinga okushisa aphezulu kanye nezindawo ezibolayo.Ukuncibilika nokusakazwa: Izinto ezikhethiwe ze-tungsten zincibilika kusetshenziswa imishini ekhethekile enezinga eliphezulu lokushisa njengeziko likagesi le-arc.I-tungsten encibilikisiwe ibe isithelwa esibunjeni ukuze kwakheke umumo wokuqala we-crucible.Inqubo yokuqamba: I-cast tungsten engenalutho ibe isingaphansi kwenqubo yokubumba ukuze ibumbe futhi yakhe umumo ofiswayo we-crucible.Lokhu kungase kuhilele izindlela ezihlukahlukene ezifana nokufoja isando, ukucindezela ukucindezela noma ukukhishwa ukuze kutholwe izilinganiso zokugcina ezidingekayo kanye nezakhiwo ze-crucible.Ukucutshungulwa Nokuqedwa: Ngemva kwenqubo yokubumba, i-crucible idlula inqubo yomshini nokuqedela ukuze icwengisise indawo yayo, isuse noma yikuphi ukukhubazeka, futhi ifinyelele ubukhulu obunembile kanye nekhwalithi yendawo edingekayo ekusetshenzisweni kwezinga lokushisa eliphezulu.Ukulawulwa Kwekhwalithi: Kuyo yonke inqubo yokukhiqiza, izinyathelo eziqinile zokulawula ikhwalithi ziyasetshenziswa ukuze kuqinisekiswe ukuthi i-tungsten crucible yokugcina ihlangabezana namazinga adingekayo ekusetshenzisweni kwesithando sokushisa okuphezulu.Lokhu kungase kuhlanganise ukuhlola okungalimazi, ukuhlolwa kobukhulu kanye nokuhlaziywa kwezinto ezibonakalayo.
Ngokulandela lezi zindlela zokukhiqiza, abakhiqizi bangakhiqiza ama-tungsten crucibles aphezulu angakwazi ukumelana namazinga okushisa aphezulu kanye nezindawo ezinokhahlo, okubenza bafanelekele ukusetshenziswa eziko lokushisa eliphezulu.
Ama-crucibles we-tungsten enziwe ngokusetshenziswa kwesithando somlilo asetshenziswa kakhulu eziko lokushisa okuphezulu ezimbonini ezahlukahlukene.Ukuhlanzeka kwempahla ye-tungsten kungu-99.95%, inokumelana okuhle kakhulu nokushisa okuphezulu futhi ifanele izinqubo zokwelashwa ezifuna ukushisa.Ezinye izinhlelo zokusebenza ezijwayelekile zifaka:
I-High Temperature Metal Melting: Izinsimbi ze-tungsten zisetshenziselwa ukuncibilika nokuphonsa izinsimbi ezincibilika kakhulu njengensimbi, ama-alloys okushisa aphezulu nezinsimbi eziphikisayo.Ezimbonini ezifana ne-aerospace, ezokukhiqiza izimoto nezensimbi, lezi zinsimbi zisiza ukucubungula insimbi encibilikisiwe emazingeni okushisa aphakeme kakhulu.Indawo ye-Vacuum ne-Inert Gas: I-Tungsten crucibles ivame ukusetshenziswa ezithandweni zokushisa eziphakeme ezisebenza endaweni ye-vacuum noma ye-inert gas.Lezi zimo zivamile ezimbonini ezifana nokwelashwa kokushisa, ukucubungula izinto ezithuthukisiwe kanye nokukhiqizwa kwe-semiconductor, lapho izakhiwo ezingaguquki ze-tungsten zibalulekile ekugcineni umoya olawulwayo kanye nokuzuza ukushisa okufanayo.Ukukhula KweCrystal kanye Nokukhiqiza I-Crystal Eyodwa: Ezimbonini ezifana ne-semiconductor kanye nokukhiqiza optical, izinsimbi ze-tungsten zisetshenziswa enqubweni yokukhula kwekristalu.Ukuhlanzeka okuphezulu nokuzinza kokushisa kwalezi zinsimbi zibalulekile ekukhiqizeni amakristalu ekhwalithi ephezulu asetshenziswa kumadivayisi kagesi kanye ne-optical.I-High Temperature Sintering and Annealing: I-Tungsten crucibles idlala indima ebalulekile ezinqubweni zokushisa okuphezulu ezifana nokucwiliswa kanye nokufaka izitsha zobumba, izinhlanganisela nezinto ezithuthukisiwe.I-crucible's conductivity enhle kakhulu yokushisa kanye nokuzinza kusiza ukwelashwa okushisa okunembile okudingekayo kulezi zinto.I-Powder Metallurgy: I-Tungsten crucibles isetshenziselwa ukukhiqiza izingxenye zensimbi neze-ceramic ngokusebenzisa inqubo ye-powder metallurgy.Ama-Crucibles ahlinzeka ngesiqukathi esithembekile sokuhlanganisa nokufaka insimbi noma izimpushana ze-ceramic emazingeni okushisa aphezulu.
Kuzo zonke lezi zinhlelo zokusebenza, ama-tungsten crucibles anezicelo zesithando somlilo abalulekile ukuze amelane namazinga okushisa aphezulu kanye nezimo zokusebenza ezinzima, okwenza kube lula ukwelashwa okushisa okusebenzayo nokunemba kwezinto eziko lokushisa okuphezulu.
