Cemented carbide yog cov khoom siv hlau ua los ntawm cov hmoov hlau metallurgy. Nws yog tsuas yog tsim los ntawm cov khoom siv tawv tawv ntawm cov hlau refractory thiab cov hlau sib txuas.

Cov khoom tseem ceeb ntawm cemented carbide muaj xws li refractory carbide hmoov xws li tungsten carbide thiab titanium carbide, nrog rau cov hmoov hlau siv los ua binders, xws li cobalt thiab npib tsib xee. Cov khoom no paub txog nws cov hardness siab, hnav tsis kam, lub zog thiab toughness, kub tsis kam thiab corrosion kuj, tshwj xeeb tshaj yog nyob rau kub kub thaum tuav cov khoom no. Lub hardness thiab hnav tsis kam ntawm cemented carbide yog qhov pib tsis hloov ntawm 500 ° C, thiab nws tseem tuaj yeem tuav lub siab tawv ntawm 1000 ° C. Yog li ntawd, nws yog siv dav hauv kev tsim cov cuab yeej txiav, cov cuab yeej drilling, ntsuas cov cuab yeej, cov pwm ua haujlwm txias thiab ntau yam hnav-tiv taus.

Nws muaj cov yam ntxwv hauv qab no:

1. High hardness: Qhov hardness ntawm cemented carbide feem ntau yog siab dua li cov khoom siv hlau zoo tib yam, uas ua rau nws muaj peev xwm tiv taus hnav thiab txiav.

2. Lub zog siab: Carbide muaj lub zog siab, tuaj yeem tiv taus siab dua thiab thauj khoom, thiab tsis yooj yim rau deform lossis tawg. (Nquag TRS ntawm 2000-3200 Mpa)

3. Hnav tsis kam: Vim nws lub siab tawv, carbide muaj kev hnav zoo heev thiab tsim nyog rau cov ntawv thov uas yuav tsum tau hnav ntev ntev.

4. Corrosion tsis kam: Carbide muaj kev tiv thaiv zoo rau feem ntau cov xov xwm corrosive thiab tuaj yeem tswj nws qhov kev ua tau zoo hauv qhov chaw hnyav.

5. Kev ruaj ntseg kub: Nws tuaj yeem tswj tau nws lub cev thiab tshuaj lom neeg ntawm qhov kub thiab txias thiab tsis yooj yim rau soften lossis deform.

6. Cov khoom siv hluav taws xob zoo thiab thermal conductivity: Qee cov cemented carbide muaj cov hluav taws xob zoo thiab thermal conductivity, ua rau nws muaj txiaj ntsig zoo hauv kev lag luam hluav taws xob thiab kev tswj xyuas thermal.

Cov khoom no ua rau cemented carbide siv dav hauv kev tsim khoom, machining, aerospace, petrochemical thiab lwm yam kev lag luam. Ntau hom carbide tuaj yeem tsim kho kom tau raws li cov kev xav tau tshwj xeeb los ntawm kev kho qhov sib xyaw thiab cov txheej txheem tsim khoom. Txawm li cas los xij, cov yam ntxwv tshwj xeeb ntawm kev ua tau zoo yuav txawv nyob ntawm cov carbide muaj pes tsawg leeg, qauv thiab txheej txheem tsim khoom. Hauv kev siv cov tswv yim, cov ntaub ntawv carbide tsim nyog yuav tsum raug xaiv raws li kev siv tshwj xeeb thiab cov kev xav tau.

CD carbide yog cov kws tshaj lij hauv tungsten carbide cov khoom xws li hnav tsis kam, cov cuab yeej mining, cov cuab yeej txiav thiab lwm yam.
