Tungsten carbide pas nrig yog tungsten carbide round bar, tseem hu ua tungsten steel bar, yooj yim hais, tungsten steel round bar lossis tungsten carbide round bar.Tungsten carbide yog cov khoom sib xyaw ua los ntawm cov hmoov hlau metallurgy thiab tsim los ntawm cov khoom siv hlau refractory (theem nyuaj) thiab cov hlau sib txuas (binder theem).
Muaj ob txoj hauv kev rau kev tsim cov tungsten carbide puag ncig tuav: ib qho yog extrusion, thiab extrusion yog ib txoj hauv kev tsim cov khoom ntev.Nws tuaj yeem raug txiav rau txhua qhov ntev uas tus neeg siv xav tau thaum lub sijhawm extrusion txheej txheem.Txawm li cas los xij, qhov ntev tag nrho tsis tuaj yeem tshaj 350mm.Lwm qhov yog compression molding, uas yog ib txoj hauv kev tsim cov khoom luv luv.Raws li lub npe qhia, cemented carbide hmoov yog nias rau hauv cov duab nrog pwm.
Cemented carbide muaj cov khoom zoo heev xws li siab hardness, hnav tsis kam, zoo zog thiab toughness, kub tsis kam, corrosion kuj, tshwj xeeb tshaj yog nws siab hardness thiab hnav tsis kam, uas tseem nyob twj ywm tsis hloov txawm nyob rau ntawm qhov kub ntawm 500 ° C, thiab tseem. muaj ib tug siab hardness ntawm 1000 ° C.Tungsten carbide yog dav siv los ua cov cuab yeej siv, xws li cov cuab yeej tig, milling cutters, planer cutters, xyaum, tho txawv cutters, thiab lwm yam, rau txiav hlau cam khwb cia hlau, non-ferrous hlau, yas, tshuaj fibers, graphite, iav, pob zeb thiab zoo tib yam. hlau, thiab tseem tuaj yeem siv los txiav cov hlau tsis muaj cua sov, cov hlau tsis muaj steel, siab manganese hlau, cov cuab yeej hlau thiab lwm yam khoom siv nyuaj ntub sib tsoo (pob zeb, ziab txee, Z-txias, granulator ---), nias (nrog rau sab siab hydraulic xovxwm los yog extruder), --- sintering (degreasing rauv, integrated rauv los yog HIP tsis tshua muaj siab rauv).
Cov ntaub ntawv raw yog ntub dej sib tsoo, ziab, kua nplaum doping, tom qab ziab thiab txo kev ntxhov siab tom qab molding los yog extrusion, thiab thaum kawg tsim cov alloy kawg dawb paug los ntawm debinding thiab sintering.
Qhov tsis zoo ntawm round bar extrusion ntau lawm yog tias lub voj voog ntau lawm ntev.Squeezing me me txoj kab uas hla puag ncig tuav hauv qab 3 hli thiab tawg ob kawg yuav nkim ib yam khoom.Qhov ntev ntawm qhov ntev ntawm cov carbide me me txoj kab uas hla puag ncig bar, qhov phem qhov ncaj ntawm qhov khoob.Ntawm chav kawm, teeb meem ncaj thiab roundness tuaj yeem txhim kho los ntawm kev sib tsoo cylindrical tom qab theem.
Lwm qhov yog compression molding, uas yog txoj kev luv luv bar Tshuag yog tsim.Raws li lub npe qhia, nws yog cov pwm uas nias cov cemented carbide hmoov rau hauv cov duab.Qhov kom zoo dua ntawm no carbide bar txoj kev yog tias nws tuaj yeem tsim nyob rau hauv ib qho dhau los thiab txo cov seem.Simplify cov txheej txheem hlau txiav thiab tshem tawm cov khoom siv qhuav ntawm txoj kev extrusion.Lub sijhawm luv luv saum toj no tuaj yeem txuag cov neeg siv khoom 7-10 hnub.
Hais lus nruj me ntsis, isostatic nias kuj yog rau compression molding.Isostatic nias yog txoj kev zoo tshaj plaws rau kev tsim cov khoom loj thiab ntev tungsten carbide puag ncig tuav.Los ntawm sab sauv thiab qis piston ntsaws ruaj ruaj, lub twj tso kua mis siab txhaj cov kua nruab nrab ntawm lub tog raj kheej siab thiab cov roj hmab pressurized, thiab lub siab yog kis los ntawm cov roj hmab pressurized los ua cov cemented carbide hmoov nias rau hauv kev sib sau.
