1.Dab tsi yog Hard Metal lossis Cemented Carbide?
Vim nws cov hardness tsis tshua muaj siab piv rau lwm cov hlau, cemented carbide feem ntau hu ua cov hlau tawv. Cov pa roj carbon me me muaj tus nqi hardness ntawm tsuas yog 160 HV30, uas yog kaum npaug qis dua li tus nqi hardness ntawm cov khoom cemented carbide, uas tuaj yeem ncav cuag 1600 HV30.
Cemented Carbide, txawm hais tias raug xa mus rau cov hlau tawv, yog cov khoom siv sib xyaw ua los ntawm cov tawv Cemented Carbide hais nyob rau hauv ib qho softer matrix ntawm nws yog xim hlau Cobalt, Nickel, los yog lwm yam hlau.
2.Dab tsi yog Cemented Carbide's Chemical Formula?
Cemented carbide muaj cov tshuaj formula WC, uas sawv cev rau wolfram carbide.
3. Dab tsi yog Cemented Carbide Keeb Kwm?
Cemented Carbide yog thawj zaug tsim nyob rau hauv lub teb chaws Yelemees nyob rau hauv lub xyoo 1920s vim hais tias muaj ib qho kev xav tau zoo rau cov khoom siv tuag uas tuaj yeem tiv taus qhov hnyav hnyav koom nrog hauv kev kos duab tungsten filaments rau cov qij. Txhua leej txhua tus siv qhov muag teev, yog li yuav tsum muaj ntau tungsten filaments rau kev tsim khoom. Tom qab ntawd, cov tib neeg tau tsim ntau yam kev siv ntxiv rau cemented carbide.
4.Yuav ua li cas yog cementitious carbon tsim?
Hmoov hlau metallurgy yog thawj txoj hauv kev siv los tsim cov cemented carbide, uas suav nrog kev sib xyaw cov hmoov ntawm cobalt thiab tungsten hauv cov pob zeb ua ntej ntxiv cov ntawv khi kom cov hmoov ua ke thaum nias.
Hauv cov txheej txheem nias, cov khoom yog compressed rau hauv cov duab uas zoo li cov khoom tiav tsim siv hydraulic presses lossis isostatic presses.
Thaum nyob rau hauv lub xeev no, cov hmoov compact yog yooj yim rau tshuab siv cov txheej txheem metalworking khoom. Peb feem ntau xa mus rau cov txheej txheem no li "Half-Machining," uas yog pes tsawg tus neeg xa mus rau nws. Cov txheej txheem rho tawm tau zoo yog xav tau vim cov neeg ua haujlwm yuav tsum tau ceev faj thaum tshem cov hmoov me me vim tias lawv yuav ua rau muaj kev phom sij rau lawv txoj kev noj qab haus huv.
Cov khoom ua tiav ib nrab carbide yog tom qab ntawd npaj tau sintered tom qab "Half-Machining." Feem ntau, qhov no yog ua los ntawm 1300 thiab 1700 degree hauv lub tshuab nqus tsev lossis HIP qhov cub. Cemented Carbide thiab cobalt matrix koom ua ke thaum lub sij hawm sintering txheej txheem los tsim ib tug ntom "Hard Metal."
Tom qab sintering, cov khoom yuav nyuaj heev rau lub tshuab uas tsuas yog pob zeb diamond sib tsoo - ib daim ntawv tshwj xeeb ntawm micro machining uas kim heev - siv tau. Vim tias txoj kev no tsis tuaj yeem tshem tawm cov khoom siv loj, nws tseem kim dua li milling steel lossis lwm yam hlau.

5.Kev siv cov hlau tawv thiab cov cemented carbide
Cemented carbides yog siv nyob rau hauv ntau yam kev lag luam. Raws li kev xyaum ua txhua yam kev lag luam siv nws, peb xa mus rau nws raws li cov hniav ntawm peb tag nrho cov niaj hnub industrial system. xws li hauv kev txiav cov cuab yeej, mining, roj thiab roj, mining, aerospace, thiab tub rog.
Txawm hais tias koj muaj lub hom phiaj twg hauv siab, xav tiv tauj Arris lossis Zhuzhou Hongtong.
