Indlela yokukhiqiza ye-tungsten carbide

I-tungsten carbideiyinhlanganisela eyakhiwe i-tungsten ne-carbon.Ukuqina kwayo kufana nedayimane.Izakhiwo zayo zamakhemikhali zizinzile kakhulu futhi zithandwa kakhulu emikhakheni ehlukahlukene yezimboni.Namuhla, uSidi Xiaobian uzokhuluma nawe mayelana nendlela yokukhiqiza ye-tungsten carbide.

Ngokwezidingo zei-tungsten carbide rollerusayizi, osayizi abahlukene be-tungsten carbide basetshenziselwa izinhloso ezahlukene.Amathuluzi okusika i-Carbide, afana nomshini wokusika i-blade emise amathuluzi okusika amise okwe-V, ingxubevange emihle enezinhlayiya ze-ultrafine subfine tungsten carbide.Ingxubevange ye-coarse usebenzisa i-medium particle tungsten carbide;I-alloy yokusika amandla adonsela phansi kanye nokusika okusindayo yenziwe nge-tungsten carbide ephakathi nendawo.Itshe elisetshenziselwa amathuluzi ezimayini linobunzima obuphezulu kanye nemithwalo enomthelela futhi lisebenzisa i-tungsten carbide eqinile.Umthelela omncane wamadwala, umthwalo omncane womthelela, onezinhlayiyana ezimaphakathi ze-tungsten carbide njengezingxenye zempahla eluhlaza ezingagugi;Ekugcizeleleni ukumelana nokugqoka, ukumelana nengcindezi kanye nokushelela kwendawo, i-ultrafine ultrafine medium particle tungsten carbide isetshenziswa njengento eluhlaza.Ithuluzi lomthelela lisebenzisa impahla eluhlaza ye-tungsten carbide ephakathi nendawo.

I-Tungsten carbide inokuqukethwe kwekhabhoni yethiyori engu-6.128% (50% ye-athomu).Lapho okuqukethwe kwekhabhoni ye-tungsten carbide kukukhulu kunokuqukethwe kwekhabhoni yethiyori, ikhabhoni yamahhala ivela ku-tungsten carbide.Ukuba khona kwekhabhoni yamahhala kwenza izinhlayiya ezizungezile ze-tungsten carbide zikhule zibe zinkulu ngesikhathi sokucwiliswa, okuholela ezinhlayiyeni ze-carbide zikasimende ezingalingani.I-Tungsten carbide ngokuvamile idinga ikhabhoni eboshwe kakhulu (≥6.07%) kanye nekhabhoni yamahhala (≤0.05%), kanti ikhabhoni iyonke incike kunqubo yokukhiqiza kanye nobubanzi bokusetshenziswa kwe-carbide enosimende.

Ngaphansi kwezimo ezijwayelekile, ingqikithi yekhabhoni ye-vacuum sintering tungsten carbide ngendlela kapharafini inqunywa ngokuyinhloko ingqikithi yokuqukethwe komoyampilo webriquette ngaphambi kokucwiliswa.Ingxenye yokuqukethwe komoya-mpilo inyuke ngengxenye engu-0.75, okungukuthi, ingqikithi yekhabhoni ye-tungsten carbide =6.13%+ okuqukethwe komoyampilo %×0.75 (kucatshangwa ukuthi kunomoya ongathathi hlangothi esithandweni somlilo, empeleni, ingqikithi yekhabhoni ye-tungsten carbide in izithando zomlilo eziningi zingaphansi kwenani elibaliwe) [4] Ingqikithi yekhabhoni equkethwe ku-tungsten carbide yaseChina ingahlukaniswa cishe ibe izinqubo ezintathu zikapharafini.

I-vacuum sintered tungsten carbide inokuqukethwe kwekhabhoni isiyonke okungaba ngu-6.18±0.03% (ikhabhoni yamahhala izonyuka).Ingqikithi yekhabhoni yokuqukethwe kwe-parafini wax i-hydrogen sintering tungsten carbide ingu-6.13±0.03%.Ingqikithi yekhabhoni yokuqukethwe kwerabha ye-hydrogen sintering tungsten carbide ingu-5.90±0.03%.Lezi zinqubo ngezinye izikhathi ziyashintshana.Ngakho-ke, inani eliphelele lekhabhoni le-tungsten carbide linqunywa ngokuya ngezimo ezithile.
