Nrog lawv cov qib hardness ze rau 85 HRC, cemented carbides yog nyob rau hauv chav kawm ntawm cov ntaub ntawv nyuaj. Raws li qhov tshwm sim, txoj hauv kev tseem ceeb siv los kho lawv tom qab sintering yog sib tsoo. Hauv kev tsim cov cuab yeej cemented carbide, kev ua haujlwm sib tsoo muab cov cuab yeej xav tau.
Dab tsi yog cov cuab yeej cemented carbide?
Cemented carbide yog khoom siv tawv siv ntau yam khoom siv txiav, nrog rau lwm yam kev siv khoom. Nws muaj cov khoom zoo ntawm carbide cemented rau hauv cov khoom sib xyaw los ntawm cov hlau nplaum.
Kev siv cov cemented carbide yog dab tsi?
Cemented carbide yog siv feem ntau hauv txiav, abrasion tsis kam, cuam tshuam tsis kam thiab cov cuab yeej mining, nrog rau ntau yam kev siv nws cov kev tiv thaiv corrosion thiab lwm yam ntxwv. Peb tsuas yog tsim cov hniav nyias nyias, siab-precision polishing daim hlau, thiab cemented carbide rods.
Yuav ua li cas cemented carbide inserts yog tsim?
Kev tsim khoom ntawm cov cuab yeej CARBIDE
granulated sib tov yog nchuav rau hauv qhov tuag kab noj thiab nias. Nws muab lub zog nruab nrab zoo li cov chalk. Tom ntej no, cov pressed compacts yog muab tso rau hauv ib tug sintering rauv thiab rhuab ntawm ib tug kub ntawm txog 1400 ° C, ua rau cemented carbide.
Vim li cas nws thiaj hu ua cemented carbide?
Lo lus "cemented" yog hais txog the tungstenCarbide hais tau raug ntes nyob rau hauv cov khoom siv hlau nplaum thiab " cemented " ua ke, tsim cov hlau sib txuas ntawm tungsten carbide hais thiab cov binder (WC - Co), hauv cov txheej txheem sintering.
