Electrodes ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm thiab qhov zoo ntawm qhov chaw vuam hauv nruab nrab zaus inverter chaw vuam tshuab. Kev xaiv kom raug thiab siv cov electrodes yog qhov tseem ceeb rau kev ua tiav cov welds zoo ib yam thiab txhim khu kev qha. Kab lus no tshawb txog cov kev xav txog kev siv thiab kev coj ua zoo tshaj plaws rau cov electrodes hauv nruab nrab zaus inverter qhov chaw vuam tshuab.
- Kev xaiv electrode: Kev xaiv cov electrodes nyob ntawm ntau yam, nrog rau cov khoom siv welded, cov txheej txheem vuam yuav tsum, thiab qhov xav tau vuam zoo. Cov hom electrodes siv nyob rau hauv nruab nrab zaus inverter chaw vuam tshuab suav nrog:
- Copper Electrodes: tooj liab electrodes tau dav siv vim lawv cov thermal conductivity zoo heev thiab tsis kam mus rau qhov kub thiab txias. Lawv tsim nyog rau ntau yam kev siv thiab tuaj yeem muab cov txiaj ntsig zoo sib xws.
- Chromium Zirconium Copper (CrZrCu) Electrodes: CrZrCu electrodes muab kev txhim khu kev ruaj khov thiab tiv taus hnav thiab yaig, ua rau lawv zoo tagnrho rau kev xav tau vuam tej yam kev mob thiab kev siv uas muaj zog steels.
- Refractory Electrodes: Refractory electrodes, xws li molybdenum los yog tungsten, yog siv rau cov ntawv tshwj xeeb uas yuav tsum tau ua hauj lwm rau huab cua kub thiab hluav taws xob conductivity.
- Electrode Maintenance: Kev saib xyuas ntawm electrodes yog qhov tseem ceeb los xyuas kom meej tias lawv qhov kev ua tau zoo thiab kev ua haujlwm ntev. Xav txog cov kev tswj xyuas hauv qab no:
- Kev tshuaj xyuas tsis tu ncua: Tshawb xyuas cov electrodes rau cov cim ntawm hnav, puas, lossis deformation. Hloov cov electrodes uas qhia qhov tseem ceeb ntawm kev hnav lossis kev puas tsuaj kom tswj tau qhov zoo sib xws.
- Ntxuav: Khaws cov electrodes kom huv si thiab tsis muaj cov khib nyiab, av, lossis cov kab mob uas tuaj yeem cuam tshuam rau lawv qhov kev ua tau zoo. Siv cov txheej txheem ntxuav kom tsim nyog thiab zam cov khoom siv abrasive uas tuaj yeem khawb lossis ua puas lub electrode nto.
- Hnav khaub ncaws los yog sib tsoo: Hnav khaub ncaws ib ntus lossis zom cov khoom siv hluav taws xob kom tshem tawm cov khoom tsim, oxidation, lossis cov pob zeb ntxhib. Cov txheej txheem no pab tswj kom muaj qhov sib luag thiab zoo ib yam electrode nto rau kev siv tau zoo thiab txhim khu kev qha.
- Electrode Cooling: Xyuas kom cov electrode txias kom zoo thaum lub vuam txheej txheem los tiv thaiv cov cua kub ntau dhau, uas tuaj yeem ua rau electrode degradation. Xav txog kev siv dej-txias electrodes los yog siv cov ntsuas cua txias kom tswj tau qhov kub thiab txias ua haujlwm.
- Kev xav txog kev siv hluav taws xob: Txhawm rau ua kom cov khoom siv hluav taws xob ua tau zoo tshaj plaws thiab ua tiav cov vuam zoo, xav txog cov kev xav hauv qab no:
- Electrode Force: Siv cov khoom siv hluav taws xob tsim nyog raws li cov khoom siv tuab thiab vuam yuav tsum tau ua. Lub zog tsis txaus tuaj yeem ua rau tsis txaus fusion, thaum lub zog ntau dhau tuaj yeem ua rau electrode sticking lossis deformation.
- Electrode Alignment: Ua kom muaj kev sib raug zoo ntawm cov electrodes kom muaj kev sib cuag thiab tam sim no txaus thaum lub vuam txheej txheem. Misalignment tuaj yeem ua rau tsis sib xws welds lossis electrode puas.
- Vuam Parameters: Teem lub vuam tsis, xws li vuam tam sim no, lub sij hawm, thiab pre-pressure, raws li cov khoom siv thiab xav tau weld zoo. Ua raws li cov chaw tsim khoom cov lus qhia thiab ua cov welds kuaj kom zoo rau qhov tsis zoo rau cov ntawv thov tshwj xeeb.
- Hloov Electrode: Tsis tu ncua saib electrode hnav thiab hloov lawv thaum tsim nyog los tswj kev ua tau zoo thiab vuam zoo. Hloov ob qho tib si electrodes ib txhij los xyuas kom muaj kev sib luag thiab kev pom lub neej ntawm electrode.
Kev xaiv electrode kom raug, kev saib xyuas, thiab kev siv yog qhov tseem ceeb rau kev ua tiav qhov zoo ntawm qhov chaw vuam hauv nruab nrab zaus inverter qhov chaw vuam tshuab. Los ntawm kev txiav txim siab txog cov khoom siv, cov kev xav tau vuam, thiab cov yam ntxwv ntawm cov electrode, cov neeg ua haujlwm tuaj yeem xaiv cov electrodes uas tsim nyog thiab siv cov kev coj ua zoo. Ua raws li kev xav txog kev siv hluav taws xob zoo, xws li kev siv quab yuam, kev sib dhos, thiab kev ua kom zoo dua qub, ua kom zoo ib yam thiab txhim khu kev qha welds. Los ntawm kev ua raws li cov lus qhia no, cov tuam ntxhab tuaj yeem ua kom zoo tshaj qhov kev ua tau zoo thiab kev ua haujlwm ntawm nruab nrab zaus inverter qhov chaw vuam tshuab thiab tsim cov khoom zoo welded.
