Vim li cas peb xaiv tungsten carbide hlau?

Ib yam li nyob rau hauv rooj plaub ntawm kev xaiv steel, xaiv qhov zoo tshaj plaws qib ntawm tungsten carbide (WC) yog cov txheej txheem nyuaj uas muaj kev cuam tshuam kev xaiv ntawm hnav-tiv taus thiab toughness / poob siab. Cemented tungsten carbide yog tsim los ntawm sintering (ntawm qhov kub siab) ua ke ntawm tungsten carbide hmoov nrog hmoov cobalt (Co), cov hlau nplaum uas ua haujlwm ua "binder" rau cov khoom tawv tungsten carbide. Lub tshav kub ntawm cov txheej txheem sintering tsis koom nrog cov tshuaj tiv thaiv ntawm 2 cov khoom, tab sis ua rau cov cobalt mus txog rau lub xeev ze-kua thiab ua zoo li cov kua nplaum encapsulating rau WC hais (uas tsis cuam tshuam los ntawm tshav kub). Ob qhov tsis muaj, uas yog qhov piv ntawm Cobalt rau WC thiab WC qhov loj me, tswj cov khoom siv ntau ntawm qhov ua rau "cemented tungsten carbide" daim.

Kev qhia txog qhov loj ntawm WC particle loj thiab feem pua ​​​​ntawm Cobalt yuav ua rau muaj kev poob siab heev (thiab muaj zog cuam tshuam) feem. Qhov loj dua WC grain loj (yog li ntawd, qhov ntau WC nto thaj chaw uas yuav tsum tau coated nrog Cobalt) thiab siv Cobalt tsawg dua, qhov hnyav dua thiab hnav-tiv taus qhov tshwm sim yuav dhau los. Txhawm rau kom tau txais kev ua tau zoo tshaj plaws los ntawm carbide ua cov khoom siv hniav, nws yog ib qho tseem ceeb kom tsis txhob muaj qhov ua tsis tiav ntawm ntug kev ua tsis tiav los ntawm chipping lossis breakage, thaum tib lub sij hawm kom ntseeg tau qhov zoo tshaj plaws hnav tsis kam.

Raws li qhov ua tau zoo, kev tsim cov ntse ntse heev, txiav cov npoo txiav tawm hais tias cov hmoov nplej zoo carbide siv rau hauv daim ntawv thov hniav (kom tiv thaiv cov nicks loj thiab cov npoo ntxhib). Muab kev siv cov carbide uas muaj qhov nruab nrab ntawm cov nplej loj ntawm 1 micron lossis tsawg dua, carbide hniav ua haujlwm; Yog li ntawd, ua rau feem ntau cuam tshuam los ntawm % ntawm Cobalt thiab ntug geometry tau teev tseg. Kev txiav cov ntawv thov uas cuam tshuam rau nruab nrab mus rau kev poob siab siab yog qhov zoo tshaj plaws los ntawm kev qhia txog 12-15 feem pua ​​​​Cobalt thiab ntug geometry uas muaj lub kaum sab xis ntawm 40º. Cov ntawv thov uas suav nrog cov khoom siv sib zog thiab tso tus nqi them rau lub neej ntev yog cov neeg sib tw zoo rau cov carbide uas muaj 6-9 feem pua ​​​​cobalt thiab muaj qhov suav nrog lub kaum sab xis ntawm 30-35º.

Tungsten Carbide yog qhov ntev tshaj plaws hnav cov khoom siv rau kev siv slitting. Peb tau pom nws hnav mus txog 75X ntev dua li cov qauv hlau. Yog tias koj xav tau cov hniav hnav ntev dua, Tungsten Carbide feem ntau muab rau koj hnav-lub neej koj xav tau kom koj cov khoom tsim tau.

Cov cuab yeej Passion tsuas yog siv qhov zoo tshaj plaws Tungsten Carbide kom paub tseeb tias peb cov neeg siv khoom tau txais lub ntsej muag ntse thiab ntev tshaj plaws hnav. PebCarbide Hniavyog tsim los ntawm cov khoom uas muaj Sub-Micron Grain Structure thiab tau dhau los ntawm HIP (Hot Isostatic Press) txheej txheem los xyuas kom meej qhov hnav ntev tshaj plaws thiab cov npoo ntse tshaj plaws. Txhua cov hniav tseem raug tshuaj xyuas nyob rau hauv kev nthuav dav rau kev tswj kom zoo.

 

Nws yog ib qho txuj ci tseem ceeb rau carbide raw khoom mus los ntawm cov hmoov particle mus rau cov khoom lag luam riam semi-tiav lawm, thiab los ntawm cov khoom ua tiav rau cov cuab yeej precision yog cov txheej txheem tsim khoom. XaivPASSION TOOL®, xaiv lub Hoobkas zoo WC, yuav yeej koj cov neeg siv khoom zoo.
