Iyini i-tungsten carbide?

I-Tungsten carbide, noma i-cemented carbide, ebizwa nangokuthi i-alloy eqinile, ibonakala njengenye yezinto ezinzima kakhulu.s emhlabeni. Empeleni, iyinsimbi, kodwa iyinhlanganiselai-ation i-tungsten, i-cobalt nezinye izinsimbi. Ukuqina okuphezulu kakhulu kwe-tungsten carbide eyenziwe njengamanje cishe ku-94 HRA, kukalwa ngendlela ye-Rockwell A. Enye yezinto eziqanjwe kakhulus ye-tungsten carbide i-tungsten, enendawo ephakeme kakhulu yokuncibilika phakathi kwazo zonke izinsimbi. I-Cobalt isebenza njengesibopho kule matrix yensimbi futhi ithuthukes amandla okugoba e-tungsten carbide. Ngenxa yokusebenza okuphezulu kwe-tungsten carbide, iyimpahla ephelele yezimboni eziningi, njengokufakwa kwe-tungsten carbide, izinduku ze-carbide kanye nezigayo zokugcina zamathuluzi okusika i-CNC; ukusika izindwani zokusika iphepha, ukusika amakhadibhodi, njll; Isihloko se-tungsten carbide siyafa, isipikili siyafa, umdwebo uyafa ngokusetshenziswa kokumelana nokugqoka; amathiphu e-tungsten carbide saw, amapuleti e-carbide, imichilo ye-carbide yokusika nokugqoka isicelo; izinkinobho ze-tungsten carbide, izikhonkwane ze-HPGR, izinsimbi zezimayini ze-carbide zezinkundla zokumba. I-Tungsten carbide impahla isetshenziswa kabanzi ngakho ibizwa nangokuthi“amazinyo ezimbonini”.

Iyini inqubo yokukhiqiza i-tungsten carbide?

1. Isinyathelo sokuqala sokwenza umkhiqizo we-tungsten carbide, ukwenza impushana. Impushana iyingxube ye-WC ne-Cobalt, ihlanganiswe ndawonye ngesilinganiso esithile. Isibonelo, uma amakhasimende edinga i-tungsten carbide heading dies, bafuna i-carbide grade YG20, ubuningi be-100 kilos. Khona-ke umenzi wempushana uzohlanganisa cishe u-18kgs we-Cobalt powder no-80kgs WC powder, ibhalansi engu-2kgs amanye ama-powder ensimbi azokwengezwa kuwo ngokuvumelana neresiphi yenkampani yebanga le-YG20. Zonke izimpushana zizofakwa emishinini yokugaya. Kunamakhono ahlukene emishini yokugaya, efana no-5kgs wamasampula, 25kgs, 50kgs, 100kgs, noma amakhulu.

2. Ngemva kokuxuba impushana, isinyathelo esilandelayo ukufutha nokomisa. Enkampanini ye-Zhuzhou Better Tungsten Carbide, kusetshenziswa umbhoshongo wokufutha, ozothuthukisa ukusebenza ngokomzimba namakhemikhali we-tungsten carbide powder. I-Powder eyenziwe nge-Spray tower inokusebenza okungcono kakhulu kuneminye imishini. Ngemva kokuqeda le nqubo, impushana ingena“ilungele ukucindezela” isimo.

3. I-powder izocindezelwa ngemuva kwe-“ilungele ukucindezela” impushana ihlolwe KULUNGILE. Kunezindlela ezahlukahlukene zokucindezela, noma sithi izindlela ezahlukahlukene zokwakha imikhiqizo ye-tungsten carbide. Isibonelo, uma imboni ikhiqiza amathiphu e-tungsten carbide saw, umshini we-auto-press uzosetshenziswa; uma kudingeka ukufa kwe-tungsten carbide enkulu, umshini wokucindezela owenziwe ngesandla uzosetshenziswa. Kukhona nezinye izindlela zokwenza imikhiqizo ye-tungsten carbide, njengokucindezela okubandayo kwe-isostatic(igama elifushane yi-CIP), kanye nemishini yokukhipha.

4. I-Sintering iyinqubo ngemva kokucindezela, futhi kuyinqubo yokugcina yokukhiqiza insimbi ye-tungsten carbide engasetshenziswa njengokuqina okuphezulu namandla aphezulu ensimbi yobunjiniyela yokusika, ukumelana nokugqoka, ukubhola, noma ezinye izinhlelo zokusebenza. Izinga lokushisa le-sintering liphezulu kuya ku-1400 centigrade. Ezingomeni ezihlukene, izinga lokushisa lizoba nomehluko othile. Emazingeni okushisa aphezulu kangaka, i-binder ingahlanganisa i-WC powder futhi yakhe isakhiwo esiqinile. Inqubo ye-sintering ingenziwa noma ngaphandle komshini ophezulu we-isostatic gas pressure(HIP).

Inqubo engenhla iyincazelo elula yenqubo yokukhiqiza i-carbide enosimende. Nakuba kubukeka kulula, ukukhiqizwa kwe-tungsten carbide kuyimboni yokuqoqa esezingeni eliphezulu. Akulula ukukhiqiza imikhiqizo ye-tungsten carbide efanelekayo. I-Tungsten iwuhlobo lwensiza engavuseleleki, uma isisetshenzisiwe, akunakwenzeka ukuthi iphinde yakheke futhi ngesikhathi esifushane. Yazisa insiza ebalulekile, qiniseka ukuthi yonke iqoqo lemikhiqizo ye-tungsten carbide ifanelekile ngaphambi kokufinyelelwa ezandleni zamakhasimende, kungesinye sezizathu ezibalulekile ezisicindezela ukuthi senze kangcono. Qhubeka uhamba, qhubeka uthuthuka!
