Uburyo bwo Gukora Utubuto twa Carbide
Uburyo bwo Gukora Utubuto twa Carbide
Carbide ya Tungsten ni kimwe mu bikoresho bikoreshwa cyane mu nganda. Akabuto ka karbide gakozwe muri tungsten karbide, kuburyo ifite imiterere ya karbide ya sima. Imiterere ya silinderi ya tungsten karbide ya bits ituma byoroha kwinjiza mubindi bikoresho ukoresheje ubushyuhe hamwe no gukanda. Kuberako buto ya karbide yinjizamo ifata ibintu byo gukomera, gukomera, no kuramba, biramenyerewe kubibona mubihe bitandukanye nko gucukura neza, gusya urutare, gukora umuhanda, nibikorwa byubucukuzi. Ariko buto ya karbide ikorwa ite? Muri iyi ngingo, tuzamenya iki kibazo.
1. Gutegura ibikoresho bito
Uburyo bukurikira bukenera ibikoresho bya WC nifu ya Cobalt. Ifu ya WC ikozwe mu bucukuzi bwa tungsten, yacukuwe kandi acibwa amande muri kamere. Amabuye y'agaciro ya Tungsten azahura na reaction ya chimique, ubanza hamwe na ogisijeni ihinduka okiside ya tungsten hanyuma hamwe na karubone ihinduka ifu ya WC.
2. Kuvanga ifu
Noneho dore intambwe yambere uburyo inganda zikora amenyo ya karbide. Inganda zizongeramo binders (ifu ya Cobalt cyangwa ifu ya Nickel) muri poro ya WC. Binders ni nka "kole" mubuzima bwacu bwa buri munsi kugirango dufashe guhuza karbide ya tungsten cyane. Abakozi bagomba gupima ifu ivanze kugirango barebe ko ishobora gukoreshwa mu ntambwe zikurikira.
3. Gusya neza
Muri ubu buryo, ifu ivanga izashyirwa mumashini ya Ball Milling hanyuma isya hamwe namazi nkamazi na Ethanol. Aya mazi ntabwo azakora muburyo bwa chimique ariko yoroshya gusya.
4. Koresha Kuma
Ubu buryo burigihe bubaho. Ariko inganda zitandukanye zirashobora guhitamo ubwoko bwimashini zitandukanye. Ubwoko bubiri bwimashini zikurikira zirasanzwe. Imwe muriyo ni Vacuum Dryer; ikindi ni Spray Kuma. Bafite ibyiza byabo. Koresha imirimo yo kumisha hamwe nubushyuhe bwinshi na gaze ya inert kugirango uhumeke amazi. Irashobora guhumeka amazi menshi, ikora neza muburyo bubiri bukurikira Kanda na Sintering. Vacuum Kuma ntabwo ikeneye ubwo bushyuhe bwo hejuru ariko bihenze kandi bisaba byinshi kubungabunga.
5. Kanda
Kugirango ukande ifu muburyo butandukanye abakiriya bakeneye, abakozi bazabanza kubumba. Utubuto twa Carbide tuza muburyo butandukanye kuburyo ushobora kubona ubwoko butandukanye bwurupfu, hamwe numutwe wa conic, umutwe wumupira, umutwe wa parabolike, cyangwa umutwe wikiyiko, hamwe na chamferi imwe cyangwa ebyiri, hamwe na pinholes cyangwa idafite. Hariho uburyo bubiri bwo gushiraho. Kubunini buto bwa buto, abakozi bazakanda kumashini ikora; kuri nini, abakozi bazakanda kumashini ya hydraulic.
6. Gucumura
Abakozi bazashyira karbide bito byanditseho isahani ya grafite no muri Hot Isostatic Pressing (HIP) Sintered Furnace munsi yubushyuhe bwa 1400˚ C. Ubushyuhe bugomba kuzamurwa kumuvuduko muke kugirango buto ya karbide igabanuke buhoro kandi birangiye buto ifite imikorere myiza. Nyuma yo gucumura, izagabanuka kandi ifite hafi kimwe cya kabiri cyijwi nka mbere.
7. Kugenzura ubuziranenge
Kugenzura ubuziranenge ni ngombwa cyane. Kwinjiza Carbide byabanje kugenzurwa kubintu nkubukomere, cobalt magnetique, na microstructure kugirango barebe ibyobo cyangwa uduce duto. Micrometero igomba gukoreshwa kugirango igenzure ubunini bwayo, uburebure, na diameter mbere yo gupakira.
Kurangiza, kubyara sima ya tungsten karbide yinjizamo bigomba gukurikiza inzira:
1. Gutegura ibikoresho bito
2. Kuvanga ifu
3. Gusya neza
4. Koresha Kuma
5. Kanda
6. Gucumura
7. Kugenzura ubuziranenge
