Cemented carbide yog ib hom khoom siv tawv uas muaj cov hlau tsis muaj zog thiab cov hlau sib txuas, uas yog tsim los ntawm cov hmoov hlau metallurgy thiab muaj kev hnav tsis kam thiab qee qhov toughness.Vim nws txoj kev ua tau zoo heev, cemented carbide yog dav siv hauv kev txiav, hnav-tiv taus qhov chaw, mining, geological drilling, roj mining, mechanical qhov chaw thiab lwm yam.
Cov txheej txheem ntau lawm ntawm cemented carbide suav nrog peb cov txheej txheem tseem ceeb: kev npaj sib tov, nias molding thiab sintering.Yog li dab tsi yog txheej txheem?
Batching txheej txheem thiab txoj cai
Ntsuas cov khoom siv raw uas yuav tsum tau muaj (tungsten carbide hmoov, cobalt hmoov, vanadium carbide hmoov, chromium carbide hmoov thiab ib qho me me ntawm cov khoom ntxiv), sib tov raws li cov lus qhia, muab tso rau hauv lub pob zeb yob los yog tov khoom rau zeb ntau yam ntaub ntawv raw. rau 40-70 teev, ntxiv 2% wax, refine thiab tusyees faib cov ntaub ntawv raw nyob rau hauv lub pob zeb, thiab ces ua kom sib tov nrog tej yam muaj pes tsawg leeg thiab particle loj yuav tsum tau los ntawm cov tshuaj tsuag kom qhuav los yog txhais tes sib tov thiab vibrating tshuaj ntsuam, kom tau raws li cov kev xav tau ntawm nias thiab sintering.Tom qab nias thiab sintering, cov cemented carbide blanks raug tso tawm thiab ntim tom qab kev tshuaj xyuas zoo.

Kev tshuaj xyuas
Lub tshuab nqus tsev yog dab tsi?
Lub tshuab nqus tsev zoo li no yog ib cheeb tsam uas muaj cov pa roj ntau me dua li atmospheric siab.Physicists feem ntau tham txog cov txiaj ntsig zoo tshaj plaws hauv lub xeev ntawm lub tshuab nqus tsev, uas lawv qee zaum hu ua lub tshuab nqus tsev lossis qhov chaw dawb.Tom qab ntawd lub tshuab nqus tsev ib nrab yog siv los sawv cev rau lub tshuab nqus tsev tsis tiav hauv chav kuaj lossis hauv qhov chaw.Ntawm qhov tod tes, hauv engineering thiab kev siv lub cev, peb txhais tau tias txhua qhov chaw qis dua atmospheric siab.
Tej yam tsis xws luag / xwm txheej hauv kev tsim cov khoom siv cemented carbide
Tracing rov qab mus rau lub hauv paus ua rau, feem ntau cov cemented carbide ntau lawm defects / xwm txheej yuav muab faib ua plaub pawg:
Cov khoom tsis xws luag (ETA theem tshwm, pawg loj loj daim ntawv, hmoov nias tawg)
Kev ua haujlwm tsis zoo (vuam tawg, hlau txiav tawg, thermal tawg)
Cov xwm txheej ib puag ncig (corrosion, erosion defects, thiab lwm yam)
Kev sib tsoo tshuab (xws li kev sib tsoo, hnav, qaug zog puas tsuaj, thiab lwm yam)
