Cov cuab yeej Carbide - cov ntsiab lus tseem ceeb rau kev paub txog kev ua haujlwm ntawm lub tshuab cuab yeej

Cov cuab yeej carbide tseem ceeb vim lawv qhov sib xyaw ua ke ntawm hardness thiab toughness.Raws li kev faib cov khoom ntawm cov hniav, nws tau muab faib ua plaub hom cuab yeej: cov cuab yeej steel, cemented carbide, ceramics, thiab superhard cov ntaub ntawv.Cov khoom siv ntawm cov cuab yeej muaj xws li hardness thiab cuam tshuam toughness.Feem ntau hais lus, qhov siab dua qhov hardness, qhov cuam tshuam toughness.Feem ntau, qhov hardness thiab toughness yuav tsum sib npaug raws li qhov tshwj xeeb daim ntawv thov teb ntawm lub cuab yeej.Vim nws cov khoom muaj txiaj ntsig zoo, cemented carbide dominates lub ntiaj teb txiav cov cuab yeej siv, suav txog 63% hauv 2021.

Carbide cuab tam kev lag luam saw: ntawm ib qho tseem ceeb ntawm qhov nruab nrab, muaj ntau lub tuam txhab nrog tag nrho kev lag luam saw layout

Carbide txiav cov cuab yeej yog nyob rau hauv feem ntau downstream ntawm tungsten kev lag luam saw, accounting rau 50% ntawm tag nrho cov tungsten noj nyob rau hauv Tuam Tshoj.Cov ntaub ntawv ntawm cov cemented carbide muaj xws li tungsten carbide, cobalt hmoov, tantalum-niobium khoom tov, thiab lwm yam. Cov dej ntws los yog cov chaw tsim khoom ntawm cov khoom siv raw.Raws li cov ntaub ntawv los ntawm Tuam Tshoj Tungsten Industry Association, 50% ntawm Tuam Tshoj tus tungsten noj nyob rau hauv 2021 yuav nyob rau hauv lub teb ntawm carbide tej cuab yeej.

Daim ntawv thov davhlau ya nyob twg ntawm cov cuab yeej txiav carbide yog qhov dav, suav nrog ntau tshaj kaum kev lag luam hauv qab.Daim ntawv thov teb ntawm cov cuab yeej cemented carbide tau nthuav dav, feem ntau yog tsom rau hauv tsib thaj chaw ntawm tsheb thiab maus taus, cov cuab yeej siv tshuab, cov tshuab dav dav, pwm, thiab cov tshuab tsim kho, suav txog 20.9%, 18.1%, 15.0%, 7.4%, 6.8%, suav txog ze li 70% ntawm tag nrho.
