Cov pas nrig cemented carbide yog ib qho tseem ceeb hauv kev tsim cov cuab yeej txiav ua haujlwm siab thiab cov khoom siv uas tsis yooj yim hnav. Cov pas nrig no yog ua los ntawm kev sib xyaw ua ke ntawm tungsten carbide thiab cobalt, uas tau sintered ua ke hauv qab siab thiab kub kom tsim tau cov khoom siv uas tawv heev thiab tsis yooj yim hnav. Cov yam ntxwv tshwj xeeb ntawm cov pas nrig cemented carbide ua rau lawv yog cov khoom siv tseem ceeb hauv ntau yam lag luam, suav nrog kev ua hlau, kev ua ntoo, kev khawb av, thiab kev tsim kho.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov cemented carbide rods yog lawv qhov nyuaj tshwj xeeb. Tungsten carbide, lub ntsiab lus tseem ceeb ntawm cov rods no, yog ib qho ntawm cov khoom siv nyuaj tshaj plaws uas tib neeg paub, thib ob tsuas yog pob zeb diamond. Qhov nyuaj no tso cai rau cov cemented carbide rods kom tiv taus qib siab ntawm kev ntxhov siab thiab kev hnav, ua rau lawv zoo tagnrho rau kev siv hauv cov cuab yeej txiav xws li drills, end mills, thiab inserts. Qhov nyuaj ntawm cemented carbide rods kuj tseem pab txhawb rau lawv lub neej ua haujlwm ntev, txo qhov zaus ntawm kev hloov cuab yeej thiab ua kom muaj txiaj ntsig ntau ntxiv hauv cov txheej txheem tsim khoom.
Ntxiv rau lawv qhov tawv, cov cemented carbide rods kuj tseem ua rau muaj kev tiv thaiv zoo heev. Cov yam ntxwv no yog qhov tseem ceeb hauv cov ntawv thov uas cov cuab yeej raug rau cov khoom siv abrasive lossis qhov kub siab, xws li hauv kev txiav hlau thiab kev ua haujlwm hauv kev khawb av. Kev tiv thaiv kev tiv thaiv ntawm cov cemented carbide rods ua kom cov ntug txiav ntawm cov cuab yeej tseem ntse thiab ua haujlwm tau ntev, ua rau kev ua haujlwm zoo dua thiab txo lub sijhawm tsis ua haujlwm rau kev saib xyuas cov cuab yeej.
Lwm yam tseem ceeb ntawm cov cemented carbide rods yog lawv lub zog compressive siab. Cov yam ntxwv no tso cai rau cov rods no kom tiv taus cov zog hnyav uas ntsib thaum lub sijhawm txiav thiab tsim cov haujlwm, ua rau lawv tsim nyog siv rau hauv cov ntawv thov hnyav. Kev sib xyaw ua ke ntawm kev tawv siab, kev tiv thaiv kev hnav, thiab lub zog compressive ua rau cov cemented carbide rods yog cov khoom siv xaiv rau cov haujlwm machining hnyav, qhov twg cov khoom siv cuab yeej ib txwm yuav sai sai hnav tawm lossis ua tsis tiav.
Cov pas nrig cemented carbide kuj paub txog lawv cov thermal conductivity zoo heev. Cov yam ntxwv no pab tshem tawm cov cua sov tsim thaum lub sijhawm txiav, txo qhov kev pheej hmoo ntawm kev puas tsuaj rau cov cuab yeej thiab ua kom lub cuab yeej siv tau ntev. Lub peev xwm ntawm cov pas nrig cemented carbide kom tswj tau lawv cov ntug txiav ntawm qhov kub siab ua rau lawv zoo rau kev siv hauv kev siv tshuab ceev ceev thiab lwm yam kev siv uas muaj kev txhawj xeeb txog kev kub ntxhov.
Qhov ua tau ntau yam ntawm cov cemented carbide rods nthuav dav tshaj li cov cuab yeej txiav, vim lawv kuj siv rau hauv kev tsim cov khoom siv tiv taus hnav rau ntau yam kev siv hauv kev lag luam. Cov khoom no suav nrog cov khoom siv rau kev khawb roj thiab roj av, cov khoom siv khawb av, thiab cov phaj hnav rau cov tshuab siv hauv kev tsim kho. Qhov tsis kam hnav thiab tawv ntawm cov cemented carbide rods ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov no, qhov twg kev ruaj khov thiab kev ua tau zoo yog qhov tseem ceeb.
Xaus lus, cov cemented carbide rods ua lub luag haujlwm tseem ceeb hauv kev tsim cov cuab yeej txiav ua haujlwm siab thiab cov khoom siv uas tsis yooj yim hnav. Lawv qhov kev sib xyaw ua ke ntawm qhov nyuaj, kev tiv thaiv kev hnav, lub zog compressive, thiab thermal conductivity ua rau lawv tsis tseem ceeb hauv ntau yam kev siv hauv kev lag luam. Raws li thev naus laus zis txuas ntxiv mus, cov cemented carbide rods yuav tsum nyob twj ywm ntawm cov ntaub ntawv siv hauv kev tsim cov cuab yeej thiab cov khoom uas tsav kev vam meej hauv ntau yam kev lag luam.
