1. Siv txoj cai tungsten Hlau
Muaj ntau ntau hom tungsten hlau cov ntaub ntawv, xws li aerobic tooj liab tungsten alloy, hmoov metallurgy tungsten hlau. Kev xaiv kom raug ntawm tungsten hlau yog qhov tseem ceeb rau nws lub neej kev pab cuam thiab cov txiaj ntsig. Piv txwv li, lub siab melting point, oxidation kuj thiab kub tsis kam ntawm aerobic tooj liab tungsten alloy tungsten hlau yog tsim rau zus tau tej cov electrodes thiab thermocouples uas hais txog kub thiab corrosion kuj. Cov hmoov hlau metallurgy tungsten hlau yog tsim rau cov roj emission electrode thiab EDM txiav cov khoom nyob rau hauv qhov chaw siab siab vim nws qhov ntom ntom zoo thiab muaj zog corrosion kuj.
2. Siv txoj kab uas hla ntawm tungsten Hlau
Qhov kev xaiv kom raug ntawm tungsten hlau txoj kab uas hla kom ruaj khov kev ua haujlwm thiab nce kev pab cuam lub neej. Feem ntau, qhov kev xaiv ntawm qhov zoo tshaj plaws tungsten hlau txoj kab uas hla tuaj yeem txo qhov arc voltage, txo qhov kev khiav hauj lwm kub, thiab yog li txo qhov thermal stress. Yog tias siv cov hlau tungsten tuab, nws tsis yog tsuas yog yooj yim rau nkim zog, tab sis kuj cuam tshuam rau nws lub neej kev pab cuam thiab kev ruaj ntseg.
3. Cia nws qhuav
Tungsten hlau electrodes yuav tsum tau khaws cia kom qhuav thaum siv. Ntev ntev raug rau cov dej noo yuav ua rau saum npoo ntawm tungsten hlau rau oxidize, yog li txo nws cov hluav taws xob conductivity thiab kev pab cuam lub neej. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum khaws cia rau hauv qhov chaw qhuav rau lub sijhawm ua ntej siv, tsis txhob siv nws tom qab ya raws, thiab xyuas thiab ziab cov electrode tsis tu ncua thaum lub sijhawm ua haujlwm.
4. Ua tib zoo saib kom tsis txhob hlawv ntau dhau
Kev siv cov tungsten hlau lub zog yog siab heev, yuav ua rau muaj kev ua haujlwm siab heev. Yog tias tsis them nyiaj rau, nws yog ib qho yooj yim uas tshwm sim ntau heev kub thiab melting teeb meem. Kev kub hnyiab ntau dhau yuav ua rau cov hlau tungsten tawg thiab yaj, cuam tshuam rau nws lub neej kev pab cuam thiab thrust. Yog li ntawd, qhov tob ntawm electrode, arc ntev thiab tam sim no ntawm tungsten hlau yuav tsum tau tswj kom pob tshab kom tswj tau qhov kub thiab txias. Hauv kev ua haujlwm siab, kev saib xyuas yuav tsum tau them nyiaj rau kev tswj lub sijhawm ua haujlwm ntawm tungsten hlau kom tsis txhob overheating thiab hlawv ntau dhau.
5. Ua tib zoo saib rau ib puag ncig
Kev hloov ntawm ib puag ncig yuav cuam tshuam rau nws qhov zoo thiab kev pabcuam lub neej. Piv txwv li, thaum siv hauv huab cua, cov tshuaj tiv thaiv oxidation yooj yim tshwm sim, cuam tshuam rau cov khoom siv hluav taws xob ntawm tungsten hlau thiab tseem ua rau tungsten hlau tawg. Thaum siv nyob rau hauv ib puag ncig kub, nws tseem yuav tsum tau them sai sai rau cov pa taws ntau dhau ntawm huab cua thiab ua kom lub melting thiab hlawv ntawm tungsten hlau. Yog li ntawd, thaum siv tungsten hlau, nws yog ib qho tsim nyog yuav tsum tau xyuam xim rau nws cov cua sov thiab corrosion kuj, thiab tsis txhob siv nyob rau hauv ib puag ncig hnyav heev.
