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.

Dab tsi yog txheej txheej txheej txheem nyob rau hauv lub ntiaj teb?
Lub neej muaj txheej txheem ntawm lub ntiaj teb yog the Biosphere. Lub neej muaj dabtsi? Cov kabmob lub neej yog qhov tseem ceeb ntawm lub sijhawm ntev ntawm cov kabmob tuaj yeem xav tau ua raws li qhov xav tau hauv kev ua haujlwm ua ntej tau teev tseg.
Cov txheej txheem twg tau siv los tsim lub npog ntsej muag ntawm agamemnon?
Lub npog ntsej muag yog tsim los ntawm rauj kub rau hauv daim ntawv nyias nyias hla daim ntawv ntoo. Nws yog peb-dimensional thiab suav nrog kev txiav tawm pob ntseg, cov ncauj lus kom ntxaws ntawm lub ntsej muag plaub hau, thiab daim tawv muag uas tshwm qhib thiab kaw ib txhij.
Cov txheej txheem huab cua twg muaj txheej txheej ozone?
Feem ntau atmospheric ozone yog concentrated nyob rau hauv ib txheej nyob rau hauv the stratosphere, li ntawm 9 txog 18 mais (15 mus rau 30 km) saum lub ntiaj teb nto (saib daim duab hauv qab). Ozone yog ib qho molecule uas muaj peb lub atoms oxygen.
Cov txheej txheem vuam twg siv cov khoom siv hluav taws xob?
Cov txheej txheem hlau inert gas (MIG)siv cov khoom siv hluav taws xob, uas feem ntau yog nyob rau hauv daim ntawv ntawm tooj liab-coated coiled hlau. Argon yog siv los tiv thaiv cov vuam, thiab ncaj qha tam sim no nrog cov electrode yog qhov zoo los tsim kom muaj cua sov ntau rau melting.
Rau cov txheej txheem lossis cov txheej txheem?
Cov txheej txheem yog feem ntau yog ntau lub npe hais txog cov qauv uas tuaj yeem txiav txim siab. Nws cov lus yog cov qauv, tab sis cov pov thawj qhia tau tias cov txheej txheem feem ntau raug siv los ua cov lus thiab ntau ntau, zoo li cov ntaub ntawv thiab cov txheej txheem thiab lawv cov lus siv tsawg dua cov ntaub ntawv thiab cov txheej txheem.
