Yuav ua li cas carbide?
Carbide hniav yog muaj nuj nqis rau lawv lub hardness, hnav tsis kam, thiab muaj peev xwm los ua kom muaj cov khoom siv tau ntev, ua rau lawv tsim nyog rau cov khoom tawv.
Carbide cov hniav yog feem ntau ua rau siv cov txheej txheem uas cuam tshuam nrog sintering tungsten carbide hmoov rau hauv daim ntawv ruaj khov rau hauv ib daim ntawv khov, ua raws li los ntawm kev ua tiav thiab ua tiav hniav. Ntawm no yog ib qib zuj zus ntawm-kauj ruam txheej txheem saib txog li cas carbide blades feem ntau tsim:
1. Raw Khoom Npaj
- 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 binder cov hlau, feem ntau yog cobalt (co), kom pab nrog Sintering txheej txheem.
- Hmoov Sib xyaw: Lub tungsten carbide hmoov thiab cobalt yog sib xyaw ua ke los ua ib qho kev sib xyaw sib xyaw. Cov sib xyaw kom sib xyaw yog ua tib zoo tswj kom ntseeg tau tias qhov tseeb muaj pes tsawg leeg rau qhov uas xav tau lub ntsej muag uas xav tau kev nyuaj thiab tawv.
2. Tseem ceeb
- Moulding: Cov hmoov sib xyaw yog muab tso rau hauv cov pwm lossis tuag thiab nias rau hauv cov duab sib cav, uas yog cov qauv me me ntawm cov hniav. Qhov no feem ntau ua tiav nyob rau hauv kev kub siab hauv tus txheej txheem hu uaTxias Isostatic Pressing (CIP) or uniaxial nias.
- Kev sau: Lub sijhawm nias, cov hniav txoj kev ntxhib yog tsim, tab sis nws tseem tsis tau muaj tuab lossis nyuaj. Cov xovxwm pab ua kom cov hmoov sib xyaw kom sib xyaw rau hauv cov yam xav tau geometry, xws li cov duab ntawm cov cuab yeej txiav lossis hniav txiav.
3. Sumining
- Siab Sintering: Tom qab nias, cov hniav undergoes ib sintering txheej txheem. Qhov no cuam tshuam nrog cua sov nias cov duab hauv lub cub tawg ntawm qhov kub tshaj plaws ntawm1,400 ° C thiab 1,600 ° C(2552 ° F rau 2912 ° F), uas ua rau cov hmoov ua ke los fuse ua ke thiab tsim cov khoom siv, cov khoom siv ntom ntom.
- Binder Tshem Tawm: Lub sijhawm sintering, cov phau ntawv cinder kuj tseem ua tiav. Nws pab lub tungsten carbide hais ua raws li ib leeg, tab sis tom qab sintering, nws kuj tseem pab muab cov hniav nws kawg hardness thiab tawv.
- Cua txias: Tom qab Sinining, cov hniav yog maj txias txias hauv ib puag ncig tswj kom tsis txhob tawg lossis distortion.
4. Sib tsoo thiab Shaping
- Kev sib tsoo: Tom qab sintering, lub carbide hniav yog feem ntau dhau heev ntxhib lossis tsis xwm yeem, yog li ntawd nws yog av los kho lub log loj lossis sib tsoo tshuab. Cov kauj ruam no yog qhov tseem ceeb rau kev tsim cov ntse ntse thiab ua kom cov hniav kom tau raws li cov lus qhia tshwj xeeb.
- Shaping thiab profiling: Nyob ntawm daim ntawv thov, cov hniav yuav dhau los ua ntxiv lossis profiling. Qhov no tuaj yeem suav nrog kev sib tsoo cov ces kaum tshwj xeeb ntawm txoj kev txiav, thov cov tsho tiv no, lossis nplua-kho hniav cov hniav sib tw tag nrho.
5. Kev kho cov kev ua tiav
- Cov txheej txheem deg (xaiv tau): Qee lub pob txha carbide tau txais kev kho ntxiv, xws li cov khoom siv ntxiv ntawm cov ntaub ntawv xws li titanium nitride (tin), txhawm rau txhim kho kev sib txhuam, thiab txo kev sib txhuam.
- Polishing: Txhawm rau txhim kho ntxiv, cov hniav yuav polished kom ua tiav txoj kev du, ua tiav saum npoo uas txo cov kev sib txhuam thiab txhim kho kev txiav tawm.
6. Kev tswj kom zoo thiab tshuaj ntsuam
- Kev Ntsuas Hardness: Lub hardness ntawm cov hniav feem ntau yog kuaj kom ntseeg tau tias nws ua tau raws li cov kev ntsuas uas yuav tsum muaj, nrog cov kev ntsuam xyuas uas suav nrog nrog rau kev sim ua rockwell lossis vickers hardness.
- Tshuaj Ntsuam Xyuas Sab: Precision yog qhov tseem ceeb heev, yog li ntawd qhov ntev ntawm cov hniav raug kuaj xyuas kom meej tias lawv muaj kev thev taus.
- Kev Kuaj Xyuas: Rau cov ntawv thov tshwj xeeb, xws li txiav lossis slitting, cov hniav yuav yauv mus kuaj tiag tiag los ua kom nws ua tau.
Huaxin cemented carbide Muab cov tungsten carbide riam thiab tawg rau peb cov neeg siv khoom los ntawm kev lag luam sib txawv thoob plaws ntiaj teb.Qhov hniav tuaj yeem teeb tsa kom haum cov cav tov. Cov ntaub ntawv hniav hniav, ntug ntev thiab cov profiles, kev kho mob thiab txheej ci tuaj yeem hloov kho rau kev siv ntau cov ntaub ntawv muaj kev lag luam
Thaum cov hniav txuas tau dhau mus rau txhua daim tshev zoo, lawv tau npaj txhij siv hauv kev lag luam ntau yam, ntim khoom, lossis lwm yam kev txiav tawm uas muaj kev ua haujlwm loj thiab ntse yog qhov tseem ceeb.
