Kev piav txog
Tungsten electrode yog qhov ua tau zoo electrode ua los ntawm tungsten cov khoom, siv nyob rau hauv vuam, electron emission thiab lwm thaj chaw. Nws cov yam ntxwv tseem ceeb suav nrog kev ua haujlwm siab (3683 degree ± 20 degree, zoo hluav taws xob thiab thermal ua haujlwm, thiab cov hluav taws xob emission zoo heev. Hauv qab no yog cov lus qhia ntxaws ntxaws rau kev faib tawm, cov yam ntxwv, thiab kev siv ntawm Tungsten Electrodes:
Kev faib tawm thiab cov yam ntxwv
🔹1. Ntshiab Tungsten Electrode (WP)
Kev sib xyaw: muaj ntau dua 99.9% tungsten thiab tsis muaj impurities.
Xim cim: ntsuab.
Cov yam ntxwv: Cov khoom siv hluav taws xob ua haujlwm siab, Arc stability yog qhov nruab nrab, tab sis cov pa hluav taws yog tsawg.
Daim Ntawv Thov: Kev Sib Txuas Lus Vuam (xws li txhuas thiab magots magnes), tus nqi qis tshaj plaws.
🔹2. Thorium tungsten electrode (wt series)
Cov khoom xyaw: doped nrog 0. 8% {2}}. 4% olium oxide (tho thorium (tho ₂).
Xim Cim: daj (WT10), liab (wt20), ntshav (wt30), txiv kab ntxwv liab (wt40).
Cov yam ntxwv: Kev ua haujlwm zoo, ruaj khov Arc pib, muaj peev xwm nqa lub peev xwm, tab sis thorium yog corporactive thiab yuav tsum tau tshwj xeeb cia khoom.
Daim Ntawv Thov: DC Vuam (Stainless hlau, Nickel Alloy, Tooj, thiab lwm yam), tshaj cov xwm txheej tam sim no.
🔹3. CERINE TUNGSTEN Electrode (WC Series)
Kev sib xyaw: doped nrog 1.8% {2}}. 2% cine oxide (CEO ₂).
Xim cim npe: Grey [^ 4 ^].
Cov yam ntxwv: Tsis siv hluav taws xob, qis arc voltage, lub neej ntev ntev, haum rau cov vuam tam sim no.
Daim Ntawv Thov: Tsawg tam sim tam sim no DC lossis AC vuam (nyias daim hlau, cov khoom siv precision).
🔹4. LANTHAN TUNGTEN Electrode (WL Series)
Kev sib xyaw: doped nrog 0. 8% {2}}. 2% lab ₂ide (la ₂ o3).
Xim Cim: Dub (WL10), Golden (WL15), xiav (WL20).
Cov yam ntxwv: Cov neeg kho kom zoo txiav cov kev ua tau zoo, cov cav tau zoo heev, muaj cov pas dej ua ke yooj yim thiab kev tswj hwm yooj yim ntawm Molten.
Daim Ntawv Thov: AC lossis DC Vuam ntawm Cov Hlau Stainless Thiab Carbon Steel.
🔹5. Zirconium tungsten electrode (wz series)
Kev sib xyaw: doped nrog 0. 15% {2}}. 9% zirconia (zro ₂).
Xim Cim: Brown (WZ3), dawb (WZ8).
Cov yam ntxwv: Cov cua kub tsis kam, tiv thaiv kev ua qias tuaj, yooj yim los tswj cov duab sib txawv ntawm qhov kawg, txo cov tungsten infiltration.
Daim Ntawv Thov: Ac Vuam ntawm Aluminium thiab Magnesium Alloys.
🔹6. Yttrium tungsten electrode (wy series)
Kev sib xyaw: doped nrog 1.7% {2}}. 2% yttrium oxide (y ₂ O3).
Xim cim: ntuj xiav.
Cov yam ntxwv: Kev ruaj khov zoo heev-kub ruaj khov, muaj zog tiv thaiv lub peev xwm, slify arc nqaj thiab tob yaj tob.
Daim Ntawv Thov: Siab Windows Vuam, Kev Lag Luam Tub Rog, Aerospace Teb.
Cim npe nrov: Tungsten Electrode, Tuam Tshoj Tungsten Electrode Cov Chaw Tsim Khoom, Chaw muag khoom, Hoobkas
