Cemented carbide yog hu ua "cov hniav ntawm kev lag luam". Nws daim ntawv thov ntau yam dav heev, suav nrog engineering, tshuab, tsheb, nkoj, optoelectronics, tub rog kev lag luam thiab lwm yam. Kev noj tungsten hauv kev lag luam cemented carbide ntau tshaj ib nrab ntawm tag nrho cov kev siv tungsten. Peb yuav qhia nws los ntawm cov ntsiab lus ntawm nws cov lus txhais, yam ntxwv, kev faib tawm thiab kev siv.

    Ua ntej, cia peb saib lub ntsiab lus ntawm cemented carbide. Cemented carbide yog cov khoom siv hlau ua los ntawm cov khoom siv tawv tawv ntawm cov hlau refractory thiab cov hlau sib txuas los ntawm cov hmoov metallurgy. Cov khoom tseem ceeb yog tungsten carbide hmoov, thiab cov ntaub ntawv muaj xws li hlau xws li cobalt, nickel, thiab molybdenum.

    Qhov thib ob, cia peb saib cov yam ntxwv ntawm cemented carbide. Cemented carbide muaj siab hardness, hnav tsis kam, lub zog thiab toughness.

    Nws hardness yog siab heev, mus txog 86 ~ 93HRA, uas yog sib npaug rau 69 ~ 81HRC. Nyob rau hauv cov xwm txheej uas lwm yam kev mob tseem tsis hloov pauv, yog tias cov ntsiab lus tungsten carbide siab dua thiab cov nplej zoo dua, qhov hardness ntawm alloy yuav ntau dua.

    Nyob rau tib lub sijhawm, nws muaj kev hnav zoo. Cov cuab yeej lub neej ntawm cemented carbide yog siab heev, 5 mus rau 80 npaug siab dua li ntawm high-speed steel txiav; Cov cuab yeej lub neej ntawm cemented carbide kuj yog siab heev, 20 mus rau 150 npaug siab dua li cov cuab yeej steel.

    Cemented carbide muaj cov cua kub zoo heev. Lub hardness tuaj yeem nyob twj ywm tsis hloov pauv ntawm 500 ° C, thiab txawm tias ntawm 1000 ° C, qhov hardness tseem siab heev.

    Nws muaj zoo heev toughness. Lub toughness ntawm cemented carbide yog txiav txim los ntawm cov hlau sib txuas. Yog tias cov ntsiab lus ntawm kev sib txuas yog siab dua, qhov khoov lub zog yog ntau dua.

    Nws muaj zog corrosion kuj. Raws li ib txwm muaj, cemented carbide tsis hnov ​​​​mob nrog hydrochloric acid thiab sulfuric acid thiab muaj zog corrosion kuj. Qhov no kuj yog vim li cas vim li cas nws tuaj yeem tsis cuam tshuam los ntawm corrosion hauv ntau qhov chaw hnyav.

    Tsis tas li ntawd, cemented carbide yog nkig heev. Qhov no yog ib qho ntawm nws qhov tsis zoo. Vim nws cov brittleness siab, nws tsis yooj yim rau txheej txheem, nws yog ib qho nyuaj rau ua cov cuab yeej nrog complex duab, thiab nws yuav tsis raug txiav.

    Thib peb, peb yuav nkag siab ntxiv txog cemented carbide los ntawm kev faib tawm. Raws li cov sib txawv binders, cemented carbide tuaj yeem muab faib ua peb pawg hauv qab no:

    Thawj qeb yog tungsten-cobalt alloy: nws cov khoom tseem ceeb yog tungsten carbide thiab cobalt, uas tuaj yeem siv los tsim cov cuab yeej txiav, pwm thiab cov khoom siv mining.

    Qib thib ob yog tungsten-titanium-cobalt alloy: nws cov khoom tseem ceeb yog tungsten carbide, titanium carbide thiab cobalt.

    Peb pawg yog tungsten-titanium-tantalum (niobium) alloy: nws cov khoom tseem ceeb yog tungsten carbide, titanium carbide, tantalum carbide (los yog niobium carbide) thiab cobalt.

    Nyob rau tib lub sijhawm, raws li cov duab sib txawv, peb tuaj yeem faib cov cemented carbide puag rau hauv peb hom: spherical, pas nrig-puab thiab phaj-puab. Yog tias nws yog cov khoom tsis yog tus qauv, nws cov duab yog tshwj xeeb thiab yuav tsum tau kho. Xidi Technology Co., Ltd. muab kev xaiv hom kev siv thiab muab cov kev pabcuam tshwj xeeb rau cov khoom tshwj xeeb uas tsis yog-tus qauv cemented carbide khoom.

    Thaum kawg, cia peb saib kev siv cov cemented carbide. Cemented carbide tuaj yeem siv los ua cov cuab yeej pob zeb drilling, cov cuab yeej mining, cov cuab yeej drilling, ntsuas cov cuab yeej, cov khoom siv tiv taus, cov pwm hlau, lub tog raj kheej liner, precision bearings, nozzles, thiab lwm yam. Sidi cov khoom carbide feem ntau muaj xws li nozzles, valve rooj thiab lub tes tsho, txiav qhov chaw, valve trims, sealing rings, pwm, hniav, rollers, rollers, thiab lwm yam.
