Yuav ua li cas carbide hniav?
Carbide hniav muaj nuj nqis rau lawv qhov tshwj xeeb hardness, hnav tsis kam, thiab muaj peev xwm tswj tau qhov ntse ntawm lub sijhawm ntev, ua rau lawv zoo tagnrho rau kev txiav cov khoom tawv.
Carbide hniav feem ntau yog ua los ntawm kev siv cov txheej txheem uas muaj sintering tungsten carbide hmoov rau hauv ib daim ntawv, ua raws li los ntawm shaping thiab tiav cov hniav. Ntawm no yog ib kauj ruam los ntawm kauj ruam qhia txog yuav ua li cas carbide hniav feem ntau tsim:
1. Kev npaj raw khoom
- Tungsten CarbideHmoov: Cov khoom tseem ceeb uas siv hauv carbide hniav yog tungsten carbide (WC), uas yog qhov sib dhos thiab cov pa roj carbon ntau. Cov hmoov daim ntawv ntawm tungsten carbide yog tov nrog ib tug binder hlau, feem ntau yog cobalt (Co), los pab nrog sintering txheej txheem.
- Hmoov Mixing: Cov tungsten carbide hmoov thiab cobalt yog sib xyaw ua ke los ua ib qho kev sib xyaw ua ke. Cov sib tov yog ua tib zoo tswj kom paub meej qhov tseeb muaj pes tsawg leeg rau qhov xav tau hniav hardness thiab toughness.
2. Nias
- Moulding: Cov hmoov sib tov yog muab tso rau hauv pwm los yog tuag thiab nias rau hauv cov duab compact, uas yog cov txheej txheem ntxhib ntawm cov hniav. Qhov no feem ntau yog ua nyob rau hauv lub siab siab nyob rau hauv ib tug txheej txheem hu uatxias isostatic nias (CIP) or uniaxial nias.
- Kev tsim: Thaum lub sij hawm nias, cov hniav ntxhib yog tsim, tab sis nws tseem tsis tau tag nrho ntom los yog tawv. Cov xovxwm pab compact cov hmoov sib tov rau hauv qhov xav tau geometry, xws li cov duab ntawm cov cuab yeej txiav los yog cov hniav.
3. Sintering
- High-temperature Sintering: Tom qab nias, cov hniav dhau los ua txheej txheem sintering. Qhov no suav nrog cua sov cov duab nias hauv lub cub tawg ntawm qhov kub thiab txias feem ntau nruab nrab ntawm1,400 ° C thiab 1,600 ° C(2552 ° F txog 2912 ° F), uas ua rau cov hmoov hmoov sib xyaw ua ke thiab tsim cov khoom siv ntom ntom.
- Kev tshem tawm Binder: Thaum lub sij hawm sintering, cobalt binder kuj ua tiav. Nws pab cov tungsten carbide hais ua ke, tab sis tom qab sintering, nws kuj pab muab cov hniav nws zaum kawg hardness thiab toughness.
- Txias: Tom qab sintering, cov hniav yog maj mam txias nyob rau hauv ib puag ncig tswj kom tsis txhob tawg los yog distortion.
4. Sib tsoo thiab Shaping
- Sib tsoo: Tom qab sintering, cov hniav carbide feem ntau yog ntxhib los yog tsis sib xws, yog li nws yog av kom meej qhov ntev uas siv lub log tshwj xeeb lossis cov tshuab sib tsoo. Cov kauj ruam no yog qhov tseem ceeb rau kev tsim cov ntug ntse thiab ua kom cov hniav ua tau raws li qhov xav tau tshwj xeeb.
- Shaping thiab Profileing: Nyob ntawm daim ntawv thov, cov hniav tuaj yeem hloov kho ntxiv lossis profileing. Qhov no tuaj yeem koom nrog kev sib tsoo cov ces kaum tshwj xeeb ntawm cov ntug txiav, siv cov txheej txheem, lossis kev kho kom zoo ntawm cov hniav tag nrho cov geometry.
5. Kev kho mob tiav
- Nto txheej (yeem): Qee cov hniav carbide tau txais kev kho mob ntxiv, xws li txheej txheej ntawm cov ntaub ntawv zoo li titanium nitride (TiN), los txhim kho hardness, hnav tsis kam, thiab txo kev sib txhuam.
- Polishing: Txhawm rau txhim kho kev ua tau zoo ntxiv, cov hniav tuaj yeem polished kom ua tiav qhov du, ua tiav qhov chaw uas txo kev sib txhuam thiab txhim kho kev txiav.
6. Kev Tswj Xyuas Zoo thiab Kev Xeem
- Kev kuaj Hardness: Lub hardness ntawm cov hniav feem ntau yog kuaj los xyuas kom meej tias nws ua tau raws li qhov yuav tsum tau specifications, nrog rau kev ntsuam xyuas xws li Rockwell los yog Vickers hardness kuaj.
- Dimensional soj ntsuam: Precision yog qhov tseem ceeb, yog li qhov ntev ntawm cov hniav raug kuaj xyuas kom ntseeg tau tias lawv ua tau raws li qhov kev cia siab.
- Kev Ntsuas Kev Ua Haujlwm: Rau cov kev siv tshwj xeeb, xws li txiav lossis txiav, cov hniav tuaj yeem raug kuaj hauv ntiaj teb tiag tiag kom ntseeg tau tias nws ua tau raws li qhov xav tau.
HUAXIN CEMENTED CARBIDE muab hwm tungsten carbide riam thiab hniav rau peb cov neeg muas zaub los ntawm txawv industries thoob plaws lub ntiaj teb no.Cov hniav yuav tsum configured kom haum cov cav tov siv nyob rau hauv zoo txhua yam kev lag luam daim ntawv thov. Cov ntaub ntawv hniav, ntug ntev thiab cov profiles, kev kho mob thiab cov txheej txheem tuaj yeem hloov kho rau kev siv nrog ntau yam khoom siv
Thaum cov hniav tau dhau tag nrho cov kev kuaj xyuas zoo, lawv tau npaj siv rau hauv ntau daim ntawv thov kev lag luam, xws li hauv kev ua haujlwm hlau, ntim khoom, lossis lwm yam kev ua haujlwm txiav uas muaj kev hnav tsis kam thiab kev ua kom zoo yog qhov tseem ceeb.
