Inqubo yokukhiqiza kanye nenqubo yokwenza izinduku ze-tungsten carbide

Kunezindlela ezimbili zokwakha zokukhiqiza imigoqo eyindilinga ye-tungsten carbide: eyodwa i-extrusion, futhi i-extrusion iyindlela efanelekile yokukhiqiza imigoqo emide.Ingancishiswa ibe yinoma ibuphi ubude obufiswa umsebenzisi ngesikhathi senqubo ye-extrusion.Nokho, ubude bubonke abunakudlula u-350mm.Enye i-compression molding, okuyindlela efanelekile yokukhiqiza isitoko esifushane sebha.Njengoba igama liphakamisa, i-carbide powder ehlanganisiwe icindezelwa ukuze ibumbe ngesikhunta.

I-carbide enosimende inochungechunge lwezakhiwo ezinhle kakhulu njengokuqina okuphezulu, ukumelana nokugqoka, amandla amahle kanye nokuqina, ukumelana nokushisa, ukumelana nokugqwala, ikakhulukazi ubulukhuni bayo obuphezulu nokumelana nokugqoka, okuhlala kungashintshile ngisho nasezingeni lokushisa elingu-500 ° C, futhi namanje inobunzima obuphezulu ku-1000 °C.I-Tungsten carbide isetshenziswa kabanzi njengezinto zamathuluzi, njengamathuluzi okuguqula, abasiki bokugaya, abasiki beplanethi, izinsimbi, abasiki abayisicefe, njll., ukusika insimbi eyinsimbi, izinsimbi ezingezona ayoni, amapulasitiki, imicu yamakhemikhali, igraphite, ingilazi, itshe nokunye okujwayelekile. insimbi, futhi ingasetshenziswa futhi ukusika insimbi engashisi, insimbi engagqwali, insimbi ephezulu yemanganese, insimbi yamathuluzi nezinye izinto ezinzima zokugaya ezimanzi (isigayo sebhola, iKhabhinethi yokomisa, i-Z-mixer, i-granulator---), ukucindezela (ngohlangothi ukucindezela kwe-hydraulic press noma i-extruder), --- i-sintering (isithando somlilo, isithando somlilo esihlanganisiwe noma isithando somlilo esiphansi se-HIP).

Izinto ezisetshenziswayo ziwukugaya okumanzi, ukomiswa, i-glue doping, bese ukomisa nokunciphisa ingcindezi ngemuva kokubunjwa noma ukukhishwa, futhi ekugcineni kwenza i-alloy yokugcina ingenalutho ngokukhipha i-sintering.

Ububi bokukhiqizwa kwe-round bar extrusion ukuthi umjikelezo wokukhiqiza mude.Ukukhama imigoqo eyindilinga emincane engaphansi kuka-3mm nokuphula iziphetho ezimbili kuzomosha inani elithile lempahla.Uma ubude bebha eyisiyingi eyisiyingi se-carbide bude, buba bubi nakakhulu ukuqina kokungenalutho.Yiqiniso, izinkinga eziqondile neziyindilinga zingathuthukiswa ngokugaya isilinda ngokuhamba kwesikhathi.

Okunye ukubunjwa kokucindezela, okuyindlela i-stock bar emfishane ekhiqizwa ngayo.Njengoba igama liphakamisa, yisikhunta esicindezela impushana ye-carbide enosimende ibe yisimo.Inzuzo yale ndlela yokwenza ibha ye-carbide yukuthi ingakhiwa ngokudlula okukodwa futhi inciphise i-scrap.Yenza kube lula inqubo yokusika ucingo futhi uqede umjikelezo wezinto ezomile wendlela ye-extrusion.Isikhathi esifushane esingenhla singasindisa amakhasimende izinsuku ezingu-7-10.

Ukukhuluma ngokuqinile, ukucindezela kwe-isostatic nakho kungokwe-compression molding.Ukucindezela kwe-Isostatic kuyindlela ekahle yokwakha yokukhiqiza amabha ayindilinga amakhulu namade e-tungsten carbide.Ngokusebenzisa izimpawu zepiston ezingaphezulu neziphansi, ipompo yokucindezela ijova uketshezi oluphakathi nendawo phakathi kwesilinda somfutho ophezulu kanye nerabha enomfutho, futhi ukucindezela kudluliselwa ngerabha ecindezelwe ukwenza impushana ye-carbide esimende icindezelwe ekwenzeni.
