Vim li cas Electrode Sticking Phenomenon nyob rau hauv nruab nrab-Frequency Inverter Spot Vuam ntawm Galvanized Steel Sheets?

Galvanized steel ntawv feem ntau yog siv nyob rau hauv ntau yam lag luam vim lawv zoo heev corrosion kuj. Txawm li cas los xij, thaum vuam galvanized steel siv lub nruab nrab zaus inverter qhov chaw vuam tshuab, qhov tshwm sim hu ua electrode sticking tuaj yeem tshwm sim. Tsab ntawv xov xwm no yog txhawm rau tshawb nrhiav qhov ua rau electrode sticking nyob rau hauv nruab nrab zaus inverter qhov chaw vuam ntawm galvanized steel los xij thiab muab kev nkag siab txog yuav ua li cas txo qhov teeb meem no.

1. Zinc Vapor thiab Contamination: Ib qho ntawm cov laj thawj tseem ceeb ntawm electrode sticking nyob rau hauv vuam galvanized steel los xij yog tso tawm zinc vapor thaum lub vuam txheej txheem. Cov kub kub tsim thaum lub sij hawm vuam tuaj yeem vaporize zinc txheej, uas tom qab ntawd condenses thiab adheres rau cov electrode nto. Cov kab mob zinc no tsim cov txheej txheem uas ua rau cov electrodes lo rau qhov chaw ua haujlwm, ua rau muaj teeb meem hauv kev sib cais electrode.
2. Tsim cov Zinc Oxide: Thaum cov zinc vapor tso tawm thaum lub sij hawm vuam reacts nrog atmospheric oxygen, nws tsim zinc oxide. Lub xub ntiag ntawm zinc oxide nyob rau ntawm qhov chaw electrode exacerbates qhov teeb meem sticking. Zinc oxide muaj cov nplaum nplaum, ua rau cov adhesion ntawm electrode thiab galvanized steel ntawv.
3. Electrode Khoom thiab Txheej: Kev xaiv ntawm cov khoom siv electrode thiab txheej tuaj yeem cuam tshuam qhov tshwm sim ntawm electrode sticking. Qee cov khoom siv hluav taws xob lossis cov txheej txheej yuav muaj kev sib raug zoo dua rau zinc, ua rau muaj feem cuam tshuam. Piv txwv li, electrodes nrog tooj liab-raws li muaj pes tsawg leeg yog feem ntau ua raws li lawv cov affinity ntau dua rau zinc.
4. Tsis txaus Electrode Cooling: Tsis txaus electrode txias tuaj yeem ua rau electrode sticking. Kev ua haujlwm vuam ua kom muaj cua sov tseem ceeb, thiab tsis muaj cov txheej txheem txias kom zoo, cov electrodes tuaj yeem ua kub heev. Qhov kub siab txhawb nqa qhov adhesion ntawm zinc vapor thiab zinc oxide rau ntawm electrode nto, uas ua rau muaj kev nplaum.

Cov tswv yim txo qis: Txhawm rau txo lossis tiv thaiv electrode sticking thaum vuam galvanized steel nplooj ntawv nrog lub nruab nrab zaus inverter qhov chaw vuam tshuab, ntau lub tswv yim tuaj yeem ua haujlwm:

1. Electrode Hnav khaub ncaws: Kev hnav khaub ncaws electrode tsis tu ncua yog qhov tseem ceeb kom tshem tawm cov zinc tsim thiab ua kom huv si ntawm electrode. Kev saib xyuas electrode kom zoo pab tiv thaiv kev sib sau ntawm zinc vapor thiab zinc oxide, txo qhov tshwm sim ntawm kev sib tsoo.
2. Electrode Coating Selection: Xaiv cov txheej electrode uas tsis tshua muaj affinity rau zinc tuaj yeem pab txo cov nplaum. Coatings nrog anti-stick zog los yog coatings tshwj xeeb uas tsim los rau vuam galvanized steel yuav raug txiav txim siab.
3. Ua kom txias txaus: Ua kom muaj qhov txias txaus ntawm cov electrodes thaum vuam yog qhov tseem ceeb. Cov txheej txheem ua kom txias kom zoo, xws li dej txias, tuaj yeem ua kom cov cua sov kom zoo thiab tiv thaiv kom tsis txhob muaj hluav taws xob ntau dhau ntawm qhov kub thiab txias, txo qhov ua tau zoo ntawm kev nplaum.
4. Optimization of Welding Parameters: Kev ua kom zoo ntawm cov vuam tsis zoo, xws li tam sim no, vuam lub sij hawm, thiab electrode quab yuam, tuaj yeem pab txo cov nplaum. Los ntawm kev nrhiav qhov zoo tshaj plaws parameter teeb tsa, cov txheej txheem vuam tuaj yeem ua kom zoo kom txo qis zinc vaporization thiab nplaum.

Qhov tshwm sim ntawm electrode sticking nyob rau hauv nruab nrab zaus inverter qhov chaw vuam ntawm galvanized steel los xij yog feem ntau yog vim qhov tso tawm ntawm zinc vapor, tsim ntawm zinc oxide, cov khoom siv electrode thiab txheej txheej, thiab tsis txaus electrode txias. Los ntawm kev siv cov tswv yim xws li kev hnav khaub ncaws electrode tsis tu ncua, xaiv cov txheej txheem electrode uas tsim nyog, ua kom cov cua txias txaus, thiab ua kom zoo dua cov vuam tsis zoo, qhov teeb meem ntawm cov nplaum tuaj yeem txo tau. Cov kev ntsuas no yuav ua rau kev ua haujlwm zoo dua, txhim kho kev tsim khoom, thiab ua haujlwm zoo dua qub thaum ua haujlwm nrog cov ntawv hlau galvanized.
