Cemented carbide pas nrig yog qhov tseem ceeb tiv thaiv nyob rau hauv kev tsim khoom ntawm kev ua tau zoo siab txiav cov cuab yeej thiab hnav-resistant seem. Cov pas nrig no tau ua los ntawm kev sib xyaw ntawm tungsten carbide thiab cobalt, uas yog sintered ua ke nyob rau hauv kev kub siab thiab kub los tsim cov khoom siv uas tsis tshua muaj zog thiab hnav-resistant. Cov khoom tshwj xeeb ntawm cov cemented carbide pas nrig ua rau lawv cov khoom tseem ceeb hauv kev ua haujlwm, xws li kev ua lag luam, kev siv ntoo, thiab kev tsim kho.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov cemented carbide pas nrig yog lawv qhov kev nyuaj siab carress. Lub cev tungsten carbide, thawj tivthaiv ntawm cov pas nrig, yog ib qho ntawm cov khoom nyuaj tshaj plaws paub rau tus txiv neej, thib ob tsuas yog pob zeb diamond. Lub hardness tso cai cem cia carbide pas nrig kom muaj kev ntxhov siab ntau raws li kev txiav cov cuab yeej xws li hnyiab, kawg mills, thiab ntxig. Lub hardness ntawm cemented carbide pas nrig kuj ua rau lawv lub neej kev pabcuam ntev, txo cov khoom siv tau ntev, txo cov khoom lag luam hauv kev tsim cov txheej txheem.
Ntxiv rau lawv lub hardness, cemented carbide pas nrig kuj pom tias yuav hnav zoo heev. Cov cuab yeej no yog qhov tseem ceeb hauv cov ntawv thov uas cov cuab yeej muaj cov ntaub ntawv muaj kev phem lossis cov haujlwm hauv kev txiav tawm thiab kev cog qoob loo ntau. Cov hnav tsis kam ntawm cov cemented carboide rods kom paub tseeb thiab siv tau rau kev txhim kho machining zoo thiab txo qis hauv qab rau cov cuab yeej.
Lwm tus yam ntxwv tseem ceeb ntawm cemented carbide pas nrig yog lawv lub siab compressive. Cov cuab yeej no tso cai rau cov pas nrig no txhawm rau tiv thaiv kev ua haujlwm heev ntsib thaum lub sijhawm txiav thiab tsim kev ua haujlwm, ua rau lawv haum rau kev siv hauv cov haujlwm hnyav. Kev sib xyaw ua ke ntawm kev tawv tawv zoo, thiab lub zog compressive ua rau cov khoom siv carbide cov khoom siv yuav ua rau cov khoom siv pleev cov khoom siv yuav nrawm nrawm lossis poob qis.
Cemented carbide pas nrig kuj tseem paub rau lawv cov thermal zoo tshaj plaws. Cov cuab yeej no pab kom dissipate kub tsim thaum lub sijhawm txiav cov txheej txheem, txo txoj kev pheej hmoo ntawm cov cuab yeej kev puas tsuaj thiab lub neej ntev. Lub peev xwm ntawm cov cemented carbide pas nrig kom tswj tau lawv cov kev txiav ntawm cov tshuab kub siab ua rau lawv siv nyob rau hauv high-ceev rau kev siv cua sov uas yog kev txhawj xeeb kub.
Cov versatility ntawm cemented carbide pas nrig txuas ntxiv ntawm kev txiav cov cuab yeej, raws li lawv tseem siv hauv kev hnav cov khoom-resistant ntawm ntau cov ntawv thov. Cov ntu no suav nrog cov khoom siv rau roj thiab roj cav, cov khoom siv tsuas, thiab hnav daim hlau rau kev siv tshuab. Qhov tshwj xeeb hnav tsis kam thiab tawv ntawm cemented carboide rods ua rau lawv xaiv qhov zoo tshaj plaws rau cov ntawv thov no, qhov twg ruaj thiab kev ua tau zoo.
Hauv kev xaus, cemented carbide pas nrig ua si ib lub luag haujlwm tseem ceeb hauv kev tsim cov cuab yeej muaj kev ua tau zoo thiab cov khoom siv-resistant. Lawv cov kev sib txuam ua ke ntawm lub hardness, hnav tsis kam, lub zog compressive, thiab thermal conductivity ua rau lawv indispensable nyob rau hauv ntau ntawm cov ntawv thov kev lag luam. Raws li thev naus laus zis txuas ntxiv mus ua ntej, tso cai carbide pas nrig yuav tsum nyob rau ntawm cov cuab yeej siv thiab cov khoom sib xyaw ua ke hauv ntau yam lag luam.
