Tuam Tshoj chaw tsim tshuaj paus WC thiab Co Tungsten carbide blanks Tungsten carbide daim hlau
Carbide phaj tseem hu ua carbide phaj thiab carbide ntawv.Nws yog ib qho ntawm ntau cov ntaub ntawv ntawm cemented carbide.Nws muaj npe tom qab nws daim ntawv luv luv (los yog square).
Cemented carbide daim hlau feem ntau yog ua los ntawm cov hlau WC tungsten carbide hmoov thiab C0 cobalt tov siv metallurgical txoj kev los ntawm hmoov, pob milling, nias, thiab qis-siab sintering.Cov khoom siv lub cev muaj kev sib cog lus zoo, tsis muaj qhov, tsis muaj hlwv, thiab qhov siab ntawm qhov siab (qhov siab dawb paug Nws tau tswj hwm ntawm +2.2 ~ ± 2.2, thiab qhov khoob zoo yog tswj ntawm ± 0.01).Cov txheej txheem ua tiav yog me me, uas tuaj yeem txhim kho koj cov khoom siv tau zoo thiab txo cov nqi ua haujlwm.
Feem ntau siv cov hlau carbide yog tungsten carbide, titanium carbide, niobium carbide thiab vanadium carbide, thiab lwm yam, uas tuaj yeem ua rau cemented carbide muaj zog hardness thiab hnav tsis kam.Cov ntawv khi ntawm cemented carbide feem ntau yog xim hlau cobalt lossis xim hlau npib tsib xee, uas tuaj yeem xyuas kom meej tias cov cemented carbide muaj qee lub zog thiab tawv.
Lub ntsiab alloy Cheebtsam ntawm cemented carbide daim hlau yog WC thiab C0.Cov ntsiab lus ntawm WC thiab Co hauv cemented carbide daim hlau rau kev siv sib txawv tsis sib xws, thiab lawv qhov kev siv ntau yam yog dav heev.
Nyob rau hauv 1923, Schroeter ntawm lub teb chaws Yelemees ntxiv 10% mus rau 20% cobalt raws li ib tug binder rau tungsten carbide hmoov thiab invented ib tug tshiab alloy ntawm tungsten carbide thiab cobalt.Nws hardness yog thib ob tsuas yog pob zeb diamond.Qhov no yog lub ntiaj teb cov khoom siv dag zog.Thawj cemented carbide.Thaum txiav cov hlau nrog lub cuab yeej ua los ntawm cov hlau no, ntug yuav hnav sai sai thiab ntug yuav txawm nti.Xyoo 1929, Schwarzkopf ntawm Tebchaws Meskas tau ntxiv qee qhov ntawm tungsten carbide thiab titanium carbide compound carbides rau cov khoom xyaw qub los txhim kho kev ua haujlwm ntawm cov cuab yeej hauv kev txiav hlau.Qhov no yog lwm qhov kev ua tiav hauv keeb kwm ntawm kev txhim kho cemented carbide.
1. Peb yuav sim peb qhov zoo tshaj plaws los teb peb cov neeg siv khoom thov tsis pub dhau 24 teev.
2. Peb yuav muaj kev sib txuas lus zoo thiab muaj txiaj ntsig nrog peb cov neeg siv khoom.
3. Peb muab kev tswj hwm zoo hauv chav kawm thawj zaug thiab kev pab cuam tom qab muag.
Lub sij hawm xa tuaj (hnub xa khoom lossis lub sijhawm xa khoom) teev los ntawm peb hauv kev txiav txim yog khi.
Tshwj tsis yog hais tias pom zoo pom zoo, lub sij hawm xa khoom raug xam los ntawm hnub txiav txim.
Nyob rau hauv cov ntaub ntawv ntawm thav duab txiav txim los yog sawv kev txiav txim, qhov kev xa khoom ntawm qhov kev thov tau pom zoo, lub sij hawm xa khoom pib txij hnub ceeb toom rau qhov ntau tau teev nyob rau hauv txhua qhov kev ceeb toom xa tawm, tshwj tsis yog tias pom zoo pom zoo.
Lub sijhawm ib txwm tau txais cov khoom ntawm peb lub hom phiaj yog qhov kev txiav txim siab.
peb lub tuam txhab
Peb thawj cov khoom lag luam los ntawm sintering rauv yog carbide taub hau dawb paug tuag hauv 2006
Peb muaj nws tus kheej tsim 48 qib thiab yuav muaj ntau dua yav tom ntej.
Peb tau hloov peb cov khoom siv ob zaug hauv 5 xyoos los xyuas kom meej qhov zoo thiab txhim kho kev ua haujlwm yog li txo tus nqi kom muaj kev sib tw ntau dua.
peb txoj kev ntseeg muaj nqis yog daws qhov teeb meem ntawm cov neeg siv khoom
