Cemented Carbide Tej cuab yeej
Tungsten carbide yog cov khoom siv dav siv hauv high-speed machining (HSM) cov cuab yeej, cov ntaub ntawv no yog tsim los ntawm cov txheej txheem hmoov metallurgy, muaj cov tawv carbide (feem ntau tungsten carbide WC) cov khoom thiab cov hlau mos mos. Tam sim no, muaj ntau pua qhov sib txawv ntawm WC-raws li cemented carbide, feem ntau lawv siv cobalt (Co) ua ib daim ntawv cog lus, npib tsib xee (Ni) thiab chromium (Cr) kuj tseem siv cov khoom sib txuas, ntxiv rau qee qhov lwm yam alloying. cov ntsiab lus tuaj yeem ntxiv. Vim li cas thiaj muaj ntau qib cemented carbide? Yuav ua li cas lub tuam txhab txiav cov cuab yeej xaiv cov cuab yeej zoo rau cov txheej txheem txiav? Txhawm rau teb cov lus nug no, cia peb xub saib ntau yam khoom uas ua rau cemented carbide yog cov khoom siv txiav zoo tagnrho.
Hardness thiab toughness:WC-Co carbide muaj qhov tshwj xeeb zoo hauv ob qho tib si hardness thiab toughness. Tungsten carbide (WC) nws tus kheej muaj qhov nyuaj siab (ntau tshaj corundum lossis alumina), thiab nws qhov hardness tsis tshua muaj qis dua thaum qhov kev khiav hauj lwm kub nce. Txawm li cas los xij, nws tsis muaj qhov toughness txaus, uas yog ib qho tseem ceeb ntawm cov cuab yeej txiav. Txhawm rau kom tau txais txiaj ntsig zoo ntawm lub siab tawv ntawm tungsten carbide thiab txhim kho nws cov tawv nqaij, cov neeg siv cov khoom siv hlau sib txuas los ua ke tungsten carbide ua ke, yog li cov khoom siv no muaj qhov nyuaj tshaj qhov siab tshaj ntawm cov hlau ceev, thiab tib lub sijhawm tuaj yeem ua tau. tiv taus lub zog txiav hauv feem ntau cov txheej txheem txiav. Tsis tas li ntawd, nws tuaj yeem tiv taus qhov kub txiav siab uas tsim los ntawm kev ua haujlwm siab ceev.
Niaj hnub no, yuav luag tag nrho WC-Co cov cuab yeej thiab cov hniav yog coated, yog li lub luag hauj lwm ntawm cov khoom siv hauv paus zoo li tsis tseem ceeb. Tab sis qhov tseeb, nws yog lub siab elastic coefficient ntawm WC-Co cov khoom (ib qho kev ntsuas ntawm nruj, chav tsev kub elastic coefficient ntawm WC-Co yog li peb zaug ntawm high-speed steel) uas muab cov txheej uas tsis deformation. puag. WC-Co matrix kuj muab qhov xav tau toughness. Cov khoom no yog cov khoom tseem ceeb ntawm WC-Co cov ntaub ntawv, tab sis nws kuj tseem tuaj yeem hloov kho cov khoom siv los ntawm kev kho cov khoom muaj pes tsawg leeg thiab micro-structure thaum tsim cov cemented carbide hmoov. Yog li ntawd, qhov tsim nyog ntawm cov cuab yeej cuab tam rau ib txoj kev tshwj xeeb yog nyob ntawm qhov pib pulverizing txheej txheem.
Txhawm rau xaus, qhov kev paub hauv paus ntawm txhua cov khoom siv txiav thiab nws qhov kev ua tau zoo yog qhov tseem ceeb thaum xaiv qhov raug. Kev txiav txim siab suav nrog cov khoom siv ua haujlwm uas yuav tsum tau ua, cov khoom siv thiab cov duab, machining tej yam kev mob thiab qib ntawm qhov zoo ntawm qhov yuav tsum tau ua rau txhua qhov haujlwm. Thaj, cemented yog qhov kev xaiv zoo rau kev txiav cov cuab yeej, ZZBETTER Carbide Tools Company muaj ntau tshaj kaum xyoo dhau los rau kev tsim khoom yuav luag txhua yam ntawm cov cuab yeej tungsten carbide.
Zoo siab txais tos hu rau peb yog tias koj muaj lus nug lossis xav tau ntawm cov cuab yeej cemented carbide, peb kuj tuaj yeem ua cov khoom tsis raug cai tsuas yog tias koj muab koj cov duab kos.
