Yuav Ua Li Cas Tsim Tungsten Carbide

Peb txhua tus paub tias carbide alloys yog tsim los ntawm tungsten carbide, tab sis koj puas paub cov lus zais ntawm yuav ua li cas tsim nws? Zaj lus no yuav qhia koj cov lus teb. Kev tsim cov cemented carbide yog sib tov cov hmoov carbide thiab cov hmoov nplej hauv ib qho kev faib ua feem, nias rau hauv ntau yam duab, thiab tom qab ntawd semi-sintered. Qhov kub ntawm sintering yog 1300-1500 ° C.

Thaum tsim cov cemented carbide, cov khoom siv raw hmoov xaiv muaj qhov loj me ntawm 1 thiab 2 microns, thiab purity siab heev. Cov ntaub ntawv raw hmoov yog sib xyaw raws li qhov sib xyaw ua ke, nws tuaj yeem ncav cuag qib sib txawv raws li qhov sib txawv ntawm WC thiab daim ntawv cog lus hmoov. Tom qab ntawd qhov nruab nrab yog ntxiv rau lub pob zeb ntub kom ntub-sib tsoo rau lawv kom lawv sib xyaw ua ke thiab crushed. Tom qab ziab thiab sieving, tus neeg sawv cev tsim yog ntxiv, thiab sib tov yog qhuav thiab sieved. Tom ntej no, thaum sib tov yog granulated thiab nias, thiab rhuab nyob ze rau lub melting point ntawm lub binder hlau (1300-1500 ° C), lub hardened theem thiab cov binder hlau yuav tsim ib tug eutectic alloy. Tom qab txias, tag nrho cov khoom yog tsim. Lub hardness ntawm cemented carbide nyob ntawm WC cov ntsiab lus thiab cov nplej loj, uas yog, qhov feem ntau ntawm WC thiab cov nplej zoo dua, qhov nyuaj dua. Lub toughness ntawm cov cuab yeej carbide yog txiav txim siab los ntawm daim ntawv cog lus hlau. Qhov siab dua cov ntsiab lus ntawm daim ntawv cog lus hlau, qhov ntau dua qhov khoov lub zog.

Koj puas xav tias tom qab txias cov khoom tiav lawm?

Lo lus teb tsis yog! Tom qab ntawd, nws yuav raug xa mus rau ntau qhov kev xeem. Tungsten carbide cov khoom tuaj yeem cuam tshuam qhov sib txawv ntawm cov khoom siv kho tshuab hauv cov khoom siv tshuaj, cov ntaub so ntswg, thiab cov txheej txheem kho cua sov. Yog li ntawd, qhov kev ntsuam xyuas hardness yog siv dav hauv kev tshuaj xyuas cov khoom carbide, uas tuaj yeem saib xyuas qhov tseeb ntawm cov txheej txheem kho cua sov thiab kev tshawb fawb ntawm cov ntaub ntawv tshiab. Lub hardness nrhiav tau ntawm tungsten carbide tsuas yog siv Rockwell hardness tester los ntsuas HRA hardness qhov tseem ceeb. Qhov kev xeem muaj ib tug muaj zog zoo thiab dimensional adaptability ntawm lub xeem daim nrog high efficiency.

Yog tias koj txaus siab rau cov khoom lag luam tungsten carbide thiab xav paub ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa US MAIL hauv qab ntawm nplooj ntawv.
