Imikhiqizo yensimbi ye-Tungsten iqukethe cishe u-18% we-tungsten, insimbi ye-tungsten ingeye-carbide enosimende, ebizwa nangokuthi i-tungsten-titanium alloy.Ukuqina buyi-10K esikalini se-Vickers, okwesibili ngemuva kwedayimane.Ngenxa yalokhu, imikhiqizo yensimbi ye-tungsten, inesici sokungelula ukugqokwa.Imikhiqizo ye-tungsten carbide ivamise ukusetshenziswa kumathuluzi e-lathe, ama-drill bits, ama-glass cutter bits, ama-tile cutters, aqinile, angesabi ukudonsa, kodwa ama-brittle.Yinsimbi engavamile.
Ukwakhiwa kwe-tungsten carbide sintering:
I-Tungsten carbide sintering molding iwukucindezela impushana ibe yimpahla futhi, bese ingena esithandweni somlilo esishiswe ngezinga elithile lokushisa 〔izinga lokushisa le-sintering〕, bese uyigcina isikhathi esithile (isikhathi sokugcina ukushisa), bese uyipholisa, ukuze uthole impahla yensimbi ye-tungsten ngokusebenza okudingekayo.
Inqubo ye-tungsten carbide sintering ingahlukaniswa ngezigaba ezine eziyisisekelo:
1: ukususwa kwe-ejenti eyakhayo, kucwiliswa isikhathi sokuqala ngokukhuphuka kwezinga lokushisa, i-ejenti eyakhayo iyabola kancane kancane noma i-vaporised, ikhishwe ngaphandle komzimba we-sintered, ngasikhathi sinye, i-ejenti eyakhayo ngaphezulu noma ngaphansi emzimbeni we-sintered. ukwanda kwekhabhoni, inani lokukhuphuka kwekhabhoni kuzoba nohlobo lwe-ejenti yokwakha, inani lenqubo ye-sintering kanye nokwehlukile noshintsho.
I-Powder surface oxides iyancishiswa, ekushiseni kwe-sintering, i-hydrogen ingancishiswa i-cobalt ne-tungsten oxides, uma ukususwa kwe-vacuum ye-ejenti eyakhayo kanye ne-sintering, ukusabela kwe-carbon ne-oksijini kungaqinile.Izinhlayiya ze-Powder zibuza ukuthi ukucindezeleka kokuxhumana kuqedwa kancane kancane, i-powder yensimbi eboshiwe yaqala ukukhiqiza imikhiqizo yokubuyisela kanye nokuhlanganisa kabusha, ukusakazeka komhlaba kwaqala ukwenzeka, amandla e-briquette athuthukile.
2: isigaba esiqinile se-sintering (800 ° c - izinga lokushisa le-eutectic)
Ezingeni lokushisa ngaphambi kokuvela kwesigaba soketshezi, ngaphezu kokuqhubeka nenqubo eyenzeka esigabeni sangaphambilini, ukusabela kwesigaba esiqinile kanye nokusabalalisa kuyaqina, ukugeleza kwepulasitiki kuyathuthukiswa, futhi umzimba we-sintered ubonakala uncipha kakhulu.
3: Isigaba se-Liquid sintering stage (izinga lokushisa eutectic - sintering temperature>)
Lapho isigaba se-liquid sibonakala emzimbeni we-sintered, ukufinyela kuqedwa ngokushesha okukhulu, kulandelwa ukuguqulwa kwe-crystalline ukuze kwakhiwe inhlangano eyisisekelo kanye nesakhiwo se-alloy.
4: Isiteji Sokupholisa (Sintering Temperature - Room Temperature>)
Kulesi sigaba, inhlangano kanye nokwakheka kwesigaba sensimbi ye-tungsten enezimo zokupholisa ezihlukene futhi ukhiqize izinguquko ezithile, ungasebenzisa lesi sici, ukwelashwa kokushisa kwensimbi ye-tungsten ukuthuthukisa izakhiwo zayo ezingokomzimba nezomshini.
Izinduku ze-tungsten ziyimikhiqizo ye-tungsten eyindilinga noma yesikwele.I-Tungsten iyinsimbi eqinile, eminyene enezinga lokushisa eliphakeme kakhulu lokuncibilika kunanoma iyiphi insimbi: 6,192°F (3,422°C).Iyingxenye yekhemikhali enenombolo ye-athomu 74. Iyingxenye yamakhemikhali enenombolo ye-athomu engu-74. I-tungsten inokumelana nokugqwala okuhle kakhulu futhi ayithinteki kancane ngama-asidi.Izinduku ze-Tungsten zikhiqizwa ngamasu okukhiqiza i-powder metallurgy.
Izinhlobo ze-Tungsten Rods Ngokuvamile zihlukaniswa zibe izinti ze-tungsten ezihlanzekile, izinduku ze-tungsten carbide, izinduku ze-tungsten alloy, izinduku zethusi ze-tungsten, izinduku zomqhubi we-tungsten nokunye.Ukusetshenziswa kwezinduku ze-Tungsten Rods Tungsten zingasetshenziswa kabanzi ekukhanyiseni, kuma-heaters kanye nobunjiniyela bemishini kagesi.Ngaphezu kwalokho, ingasetshenziswa ukwenza umthombo wokukhanya kagesi, amalambu emoto kanye nogandaganda, ukwenza izinti ze-lattice side, amafreyimu, izintambo, ama-electrode, ama-heaters kanye nezinto zokuxhumana, izinsimbi ze-PCB, izinsimbi zokubhoboza, izigayo zokugcina nokunye.
I-Zigong Xinhua Industrial supply yezinduku ze-tungsten ingakhiqizwa ngezicucu zobude obungahleliwe noma isikwe ubude obufiswa ikhasimende ngobubanzi obusuka kumayintshi angu-0.020 ukuya ku-0.750 amayintshi.Ukubekezelelana okuncane kungacashunwa ngokucela.Ngaphezu kwalokho, ama-surface finishes amathathu ahlukene noma ukwelapha okungaphezulu kuyatholakala kuye ngokusetshenziswa kokuphela okufunayo.
