Kev tsim cov txheej txheem ntawm Cemented Carbide feem ntau hais tias txhawm rau txhim kho kev ua haujlwm zoo, peb qhov tseem ceeb ntawm kev txiav - txiav ceev, qhov tob ntawm kev txiav, thiab pub tus nqi - yuav tsum tau ua kom zoo, vim qhov no feem ntau yog qhov yooj yim tshaj plaws thiab ncaj qha mus kom ze. Txawm li cas los xij, kev nce cov kev txwv no feem ntau txwv los ntawm cov xwm txheej ntawm cov cuab yeej siv tshuab uas twb muaj lawm. Yog li ntawd, txoj kev pheej yig tshaj plaws thiab yooj yim tshaj plaws yog xaiv cov cuab yeej zoo.Cemented carbide cov cuab yeej tam sim no yog lub hauv paus hauv kev lag luam. Qhov zoo ntawm cov cemented carbide yog txiav txim los ntawm peb yam: cov cemented carbide matrix (skeleton), cov qauv thiab cov duab ntawm cov hniav ( nqaij tawv), thiab txheej ( tawv nqaij ). Niaj hnub no, peb yuav siv qhov tob tob rau hauv cov cuab yeej machining, los ntawm "skeleton mus rau lub cev." Cov ntsiab lus ntawm Cemented Carbide Matrix Cov cemented carbide matrix muaj ob lub ntsiab lus tseem ceeb:
Hardening Phase: Qhov no suav nrog cov ntaub ntawv xws li tungsten carbide (WC) thiab titanium carbide (TiC), uas pib ua hmoov.
Tsis txhob kwv yees cov hmoov no - lawv yog cov khoom siv tseem ceeb rau tag nrho cov cemented carbides.
Tungsten Carbide ntau lawm:Tungsten carbide yog tsim los ntawm tungsten thiab carbon. Tungsten hmoov nrog qhov nruab nrab particle loj ntawm 3-5 μm yog tov nrog carbon dub nyob rau hauv ib lub pob zeb rau qhuav blending. Tom qab sib tov zoo, qhov sib tov yog muab tso rau hauv ib lub tais graphite thiab rhuab nyob rau hauv ib tug graphite kuj rauv rau 1400-1700 ° C. Ntawm qhov kub siab no, cov tshuaj tiv thaiv tsim tungsten carbide.
Khoom:Tungsten carbide yog ib qho khoom siv tawv heev tab sis nkig nrog lub melting point saum 2000 ° C, qee zaum tshaj 4000 ° C. Nws txiav txim siab cov alloy siab hardness thiab hnav tsis kam.
Binder Hlau: Feem ntau, cov hlau pawg hlau xws li cobalt (Co) thiab npib tsib xee (Ni) yog siv, nrog cobalt feem ntau siv hauv machining.
Piv txwv li, thaum tungsten carbide tov nrog cobalt, cov ntsiab lus cobalt tseem ceeb heev rau cov khoom ntawm cemented carbide. Cov ntsiab lus cobalt siab dua txhim kho toughness, thaum cov ntsiab lus qis cobalt txhim kho hardness thiab hnav tsis kam.
Kev tsim khoom
1. Powder Preparation (Wet Milling) Nyob rau hauv lub milling chamber, cov ntaub ntawv raw yog av rau qhov xav tau particle loj nyob rau hauv ib puag ncig nrog ethanol, dej, thiab organic binders. Cov txheej txheem no, hu ua ntub milling, suav nrog ntxiv cov organic lossis inorganic cov kuab tshuaj raws li kev sib tsoo.
▶ Yog vim li cas ntub Milling?
▶ Qhuav milling tsuas tuaj yeem zom cov ntaub ntawv mus rau qib micron (piv txwv li, siab dua 20 μm) vim tias, hauv qab qhov loj me no, electrostatic attraction ua rau cov khoom sib tsoo hnyav, ua rau sib tsoo nyuaj ntxiv.
▶ Kev sib tsoo ntub dej, nrog rau kev cuam tshuam ntawm kev sib tsoo, tuaj yeem txo qhov me me rau ob peb microns lossis txawm nanometers.
▶ Lub Sij Hawm: Nyob ntawm cov khoom siv raw, ntub milling yuav siv li ntawm 8-55 teev, ua rau cov khoom tsis sib xws ntawm cov khoom siv raw.
2. Txau DryingCov kua sib tov yog muab tso rau hauv lub tshuab ziab khaub ncaws, qhov twg cov roj nitrogen kub evaporates cov ethanol thiab dej, tawm hauv cov hmoov nplej sib npaug.
▶ Cov hmoov qhuav qhuav muaj cov thooj kheej kheej nrog txoj kab uas hla ntawm 20-200 μm. Txhawm rau muab qhov no rau hauv kev xav, cov hmoov zoo tshaj plaws yog tsawg dua ib nrab ntawm cov plaub hau tib neeg.
▶ Cov qhuav slurry raug xa mus rau kev soj ntsuam zoo kom ntseeg tau tias muaj kev sib xws.
3. Nias Cov hmoov tshuaj xyuas yog pub rau hauv lub tshuab nias los tsim cov cuab yeej ntxig.
▶ Cov pwm nias yog muab tso rau hauv lub tshuab, thiab cov punch thiab tuag yog tswj kom nias cov hmoov rau hauv cov duab thiab qhov loj ntawm lub cuab yeej.
▶ Nyob ntawm hom ntxig, qhov xav tau siab tuaj yeem ncav cuag 12 tons.
▶ Tom qab nias, txhua qhov ntxig yog ntsuas kom zoo thiab raug.
4. SinteringCov ntaub ntawv tshiab uas tau hloov pauv yog qhov tsis yooj yim heev thiab yuav tsum tau ua kom tawv rau hauv lub qhov cub sintering.
▶ Cov khoom siv tau txais 13 teev ntawm kev kho cua sov ntawm 1500 ° C, qhov twg cov molten cobalt khi nrog cov tungsten carbide hais. Thaum 1500 ° C, hlau yuav yaj sai li cov qhob noom xim kasfes.
▶ Thaum lub sij hawm sintering, polyethylene glycol (PEG) nyob rau hauv qhov sib tov evaporates, thiab cov ntaub ntawv ntim shrinks los ntawm kwv yees li 50%, ua tiav ib theem ntawm hardness.
5. Kev kho deg (Honing thiab txheej) Kom ua tiav qhov ntev, cov ntxig ntxig rau honing los zom rau saum thiab hauv qab.
▶ Txij li thaum sintered cemented carbide inserts yog ib qho nyuaj heev, muaj pob zeb diamond sib tsoo log yog siv rau precision sib tsoo.
▶ Cov kauj ruam no xav tau kev ua haujlwm siab hauv kev sib tsoo tshuab. Piv txwv li, Sweden ntiav 6-axis sib tsoo tshuab ua kom tau raws li cov kev cai nruj heev.
Tom qab kev sib tsoo, cov ntawv ntxig yog ntxuav, coated, thiab raug soj ntsuam zoo kawg nkaus.
