Yuav ua li cas xaiv cov khoom siv electrode ntawm nruab nrab zaus qhov chaw vuam tshuab? Spot vuam electrode taub hau los ntawm qhov tam sim no ntawm ntau txhiab mus rau kaum tawm txhiab tus amperes, tiv taus qhov voltage ntawm 9.81 ~ 49.1MPa, instantaneous kub ntawm 600 ℃ ~ 900 ℃. Yog li ntawd, cov electrode yuav tsum muaj hluav taws xob zoo conductivity, thermal conductivity, thermal hardness thiab siab corrosion kuj.
Spot vuam electrodes yog ua los ntawm tooj liab alloys. Txhawm rau txhim kho kev ua tau zoo ntawm tooj liab alloy electrodes, feem ntau yuav tsum tau ua kom muaj zog ntxiv, xws li: kev ua haujlwm txias, ntxiv dag zog rau lub zog, kev laus nag lossis daus ntxiv zog thiab dispersion ntxiv zog. Qhov kev ua tau zoo ntawm cov electrode kuj hloov pauv tom qab kev kho kom muaj zog sib txawv. Thaum txias-dov hlau phaj, galvanized steel daim hlau, stainless hlau los yog txhuas daim hlau yuav tsum tau welded, tsim nyog cov ntaub ntawv electrode yuav tsum tau xaiv raws li cov khoom ntawm cov ntaub ntawv phaj.
Kev xaiv cov khoom siv hluav taws xob rau qhov chaw vuam galvanized steel phaj yuav tsum txo qhov stain thiab deformation ntawm electrode thaum lub sij hawm vuam, uas yuav tsum tau muaj zog hardness, zoo hluav taws xob thiab thermal conductivity ntawm electrode ntawm qhov kub thiab txias, thiab me me alloying nyiam nrog zinc.
Lub neej electrode ntawm galvanized steel phaj vuam nrog ob peb cov khoom siv electrode ntev dua li ntawm cadmium tooj liab electrode. Vim hais tias txawm hais tias cov hluav taws xob thiab thermal conductivity ntawm cadmium tooj liab zoo dua, nws feem ntau ntseeg tias qhov adhesion ntawm zinc tsawg dua, tab sis qhov tseeb, vim nws tsis tshua muaj softening kub, qhov cuam tshuam ntawm kub hardness yog ntau dua. Lub siab kub hardness ntawm zirconium tooj liab yog siab dua, yog li nws lub neej kuj ntev dua. Txawm hais tias qhov kub thiab txias hardness ntawm beryllium pob zeb diamond tooj yog siab dua, vim hais tias nws cov conductivity yog heev phem dua li ntawm chromium-zirconium tooj liab, conductivity thiab thermal conductivity ua si lub luag hauj lwm tseem ceeb nyob rau hauv lub neej ntawm nws lub neej, thiab nws electrode lub neej yog tsawg.
Tsis tas li ntawd, kev siv tungsten (los yog molybdenum) embedded composite electrode vuam galvanized steel phaj, nws lub neej kuj siab dua, txawm hais tias cov conductivity ntawm tungsten, molybdenum yog tsawg, tsuas yog hais txog 1/3 ntawm chromium tooj liab, tab sis nws softening kub yog siab. (1273K), kub hardness (tshwj xeeb tshaj yog tungsten), cov electrode tsis yooj yim rau deformation.
