Xaiv cov khoom siv electrode rau nruab nrab zaus qhov chaw vuam tshuab?

Xaiv cov khoom siv hluav taws xob tsim nyog yog qhov kev txiav txim siab tseem ceeb hauv kev ua kom muaj txiaj ntsig thiab ua haujlwm ntev ntawm nruab nrab zaus qhov chaw vuam tshuab. Kab lus no tham txog yam yuav tsum tau xav txog thaum xaiv cov khoom siv electrode thiab muab kev nkag siab txog cov txheej txheem xaiv.

1. Workpiece Khoom Compatibility:Cov khoom siv electrode yuav tsum sib haum nrog cov khoom siv welded. Nws yog ib qho tseem ceeb uas yuav tau xav txog yam xws li conductivity, thermal expansion, thiab chemical reactivity los tiv thaiv cov ntaub ntawv hloov mus thiab paug thaum vuam.
2. Electrode Hnav Resistance:Xaiv cov ntaub ntawv uas muaj siab hnav tsis kam tiv taus cov neeg kho tshuab thiab thermal stresses ntsib thaum lub sij hawm vuam ua haujlwm. Cov ntaub ntawv xws li tooj liab alloys, chromium tooj liab, thiab refractory hlau yog paub rau lawv hnav tsis kam.
3. Thaum tshav kub kub Resistance thiab Thermal conductivity:Electrodes yuav tsum muaj cov cua kub zoo tiv thaiv kom tsis txhob ntxov deformation los yog melting thaum vuam. Tsis tas li ntawd, ib theem tsim nyog ntawm thermal conductivity pab nyob rau hauv zoo dissipating tshav kub generated thaum lub sij hawm vuam txheej txheem.
4. Hluav taws xob conductivity:Kev siv hluav taws xob siab yog qhov tseem ceeb rau kev hloov hluav taws xob zoo los ntawm lub tshuab vuam mus rau qhov chaw ua haujlwm. Tooj liab thiab nws cov alloys, vim lawv cov conductivity zoo heev, feem ntau siv cov ntaub ntawv electrode.
5. Corrosion Resistance:Xav txog qhov chaw vuam los xaiv cov ntaub ntawv uas muaj kev tiv thaiv corrosion txaus. Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog thaum ua hauj lwm nrog cov ntaub ntawv uas raug corrosion los yog nyob rau hauv cov huab cua ntub.
6. Nqi thiab Muaj:Sib npaug kev ua tau zoo nrog tus nqi yog qhov tseem ceeb. Thaum cov ntaub ntawv zoo li tooj liab tungsten muaj cov khoom tshwj xeeb, lawv tuaj yeem ua tus nqi ntau dua. Ntsuas cov kev xav tau ntawm vuam thiab kev txwv nyiaj txiag thaum xaiv cov khoom siv electrode.
7. Nto tiav thiab txheej:Qee daim ntawv thov tau txais txiaj ntsig los ntawm cov txheej txheem electrode uas txhim kho kev hnav tsis kam, tiv thaiv kev sib tsoo, lossis txo qhov tawg. Txheej zoo li chrome plating los yog electrode hnav khaub ncaws tuaj yeem txuas ntxiv lub neej ntawm electrode.

Xaiv cov khoom siv electrode:

1. Copper thiab Copper Alloys:Cov no yog dav siv rau lawv cov hluav taws xob zoo heev, thermal conductivity, thiab hnav tsis kam. Alloys xws li Class 2 (C18200) thiab Class 3 (C18150) tooj liab alloys yog cov kev xaiv ntau.
2. Chromium tooj liab:Chromium tooj liab alloys (CuCrZr) muab siab hnav tsis kam, zoo hluav taws xob conductivity, thiab thermal stability. Lawv tsim nyog rau kev thov vuam daim ntawv thov.
3. Tungsten-Copper Alloys:Tungsten-tooj ​​liab electrodes muab cov khoom ntawm tungsten lub siab melting point thiab tooj liab conductivity. Lawv tsim nyog rau daim ntawv thov uas yuav tsum tau muaj qhov kub thiab txias.
4. Molybdenum:Molybdenum electrodes yog siv rau cov ntawv tshwj xeeb uas yuav tsum tau muaj kev kub ntxhov thiab tsis tshua muaj thermal expansion.

Kev xaiv ntawm cov khoom siv electrode rau nruab nrab zaus qhov chaw vuam tshuab nyob ntawm ntau yam, suav nrog kev sib raug zoo nrog cov khoom siv ua haujlwm, hnav tsis kam, tiv thaiv tshav kub, hluav taws xob conductivity, thiab nqi. Los ntawm ua tib zoo tshuaj xyuas cov xwm txheej no thiab nkag siab txog cov kev xav tau tshwj xeeb ntawm vuam, cov tuam ntxhab tuaj yeem xaiv cov khoom siv hluav taws xob zoo tshaj plaws uas ua rau muaj txiaj ntsig zoo thiab ua haujlwm vuam zoo.
