Vim li cas 0.18mm Molybdenum Hlau Melting Point Key rau Stable Hlau EDM?

Ntau tus qub tub rog cov kws tshaj lij hauv cov tuam txhab pwm tau hais rau kuv ib yam: tooj dag hlau yuav dheev tawg tom qab ib pliag, ua rau lub tshuab nres rau ib nrab teev. Thaum maj nrawm kom tau raws li lub sijhawm kawg, lawv yuav luag xav muab cov xaim ncaj qha rau hauv lub tshuab. Tab sis tom qab hloov mus rau 0.18mm molybdenum xaim, cov xov tooj ntawm cov hlau tawg tuaj yeem suav ntawm ib sab tes tom qab ua haujlwm tag nrho. Qhov no tsis yog koob hmoov; nws yog 2623℃melting point ntawm molybdenum hlau uas muab kev tiv thaiv tsim nyog. Cia peb tham txog qhov xwm txheej tiag tiag hauv kev lag luam. Hlau EDM tseem ceeb nyob ntawm siab - zaus pulse tawm kom "hlawv" deb ntawm cov khoom me me ntawm cov khoom ua haujlwm. Qhov kub hauv zos tuaj yeem ncav cuag ntau txhiab degrees Celsius thaum lub sijhawm tawm. Lub melting point ntawm zoo tib yam tooj dag hlau tsuas yog nyob ib ncig ntawm 900 degree. Nws softens, stretches, thiab deforms yooj yim thaum rhuab, nws thiaj li melting thiab tawg. Qhov tshwm sim? Thaum cov hlau tawg, qhov kev pab cuam cuam tshuam, thiab tus neeg teb xov tooj yuav tsum rov- xov hlau, xoom nws, thiab nrhiav qhov tawg, uas yuav siv sij hawm tsawg kawg 20-30 feeb. Thaum ntsib nrog kev ua haujlwm loj, kev poob qis ib leeg tuaj yeem yog qhov teeb meem loj.

Txawm li cas los xij, 0.18mm molybdenum hlau yog txawv kiag li. Nws melting point yog siab 2623 degree, ze li peb zaug siab tshaj tooj dag. Thaum lub sij hawm txiav txim tiag tiag, txawm tias muaj zog tso tawm, cov hlau nws tus kheej yuav tsis yooj yim soften los yog yaj. Qhov no ncaj qha ua rau peb pom kev hloov pauv: Ua ntej, txuas ntxiv txuas ntxiv lub sijhawm txiav. Ib qho ntawm peb cov neeg siv khoom, lub tsheb pwm tsim, siv los ua 3-5 zaug ib yob nrog tooj dag hlau. Tam sim no, siv peb 0.18mm molybdenum hlau, ib yob yog yuav luag tag tsis tawg, nrog rau kev ua haujlwm ntev tshaj plaws rau 48 teev yam tsis muaj downtime. Qhov thib ob, kev txiav tsis tuaj yeem ua siab tawv ntxiv. Vim tias cov hlau tsis yooj yim "lov," koj tuaj yeem tsim nyog nce lub ncov tam sim no thiab mem tes dav, ib txwm ua rau kev txiav ceev. Ntau lub chaw tsim khoom tau tshaj tawm tias lub sijhawm ua tiav ntawm ib thooj tau raug txo los ntawm 15-25% tom qab hloov cov xov hlau. Thib peb, ruaj khov dua qhov zoo. tooj dag hlau deforms yooj yim thaum rhuab, ua rau cov hluav taws xob tsis sib xws (EDR) thiab kab txaij thiab micro-qhov ntawm qhov chaw txiav. Molybdenum xaim, ntawm qhov tod tes, tiv taus qhov kub thiab txias, tswj kev ua kom zoo ib yam EDR nrog tus nqi ruaj khov Ra ntawm 0.2-0.4μm, tshem tawm qhov xav tau rau cov kauj ruam tom ntej polishing.

Qhov no tsis yog lab cov ntaub ntawv; nws yog -cov ntaub ntawv ntiaj teb no los ntawm ntau tshaj ib xyoos ntawm kev sim nrog ntau lub tuam txhab pwm thiab cov chaw ua haujlwm hauv aerospace. Lub siab melting point ntawm molybdenum hlau yog tshwj xeeb tshaj yog zoo thaum machining nyuaj - rau - txiav cov ntaub ntawv xws li cemented carbide, titanium alloys, thiab siab - kub alloys - tooj dag hlau tsuas yog tsis tuaj yeem tiv tshav kub, thaum molybdenum hlau hlawv tsis tu ncua. Tau kawg, qhov siab melting point yog qhov pib xwb. Peb nruj me ntsis tswj txoj kab uas hla mus rau lub golden loj ntawm 0.18mm, nrog ib tug kam rau ua ntawm ± 0.01mm, straightness tsawg tshaj li los yog sib npaug zos rau 0.5mm / m, thiab tensile lub zog tsis tu ncua saum toj no 1500MPa kom paub qhov zoo dua. Ntau tus neeg muas zaub tau pib tsis ntseeg thaum lawv thawj zaug sim, tab sis tom qab sim ob lub yob, lawv tshem tawm tag nrho lawv cov khoom muag tooj dag thiab muab tso rau ntau qhov kev txiav txim.

Yog tias koj tseem tab tom tawm tsam nrog cov teeb meem tsis tu ncua xws li xaim tawg, poob qis, thiab kev ua haujlwm tsis zoo, xav txog kev tsom mus rau qhov tseem ceeb tseem ceeb: melting point . 0.18mm molybdenum hlau tsis yog tsuas yog hloov cov hlau; Nws yog hais txog kev txhawb nqa kev ruaj ntseg ntawm tag nrho cov xaim EDM txheej txheem los ntawm qhov kev txiav txim ntawm qhov loj. Xav kom peb xa koj cov qauv rau ntawm - qhov chaw kuaj? Los yog, raws li koj cov khoom siv tam sim no thiab cov khoom siv ua haujlwm, peb puas tuaj yeem pab koj xaiv qhov tsim nyog tshaj plaws thiab cov lus qhia tshwj xeeb? Tiv tauj peb txhua lub sijhawm. Peb tuav cov khoom lag luam ntawm 0.18mm hlau, nrog rau cov qauv muaj los ntawm 10kg mus txog. Kuaj ua ntej koj yuav -zero risk. Factories uas tau siv tiag tiag nkag siab: nyob rau hauv siab -kev tsim khoom kawg, xaiv txoj cai xaim uas muaj peev xwm tiv taus qhov kub thiab txias feem ntau yog qhov pib ntawm stabilizing ntau lawm.
