Feem ntau, txoj kab uas hla ntawmmolybdenum electrodesyog nyob nruab nrab ntawm 35 thiab 75 hli, thiab qhov loj ntawm molybdenum electrodes yog txiav txim los ntawm qhov ceev tam sim no. Thaum smelting borosilicate iav, ib qho electrode nrog ib txoj kab uas hla ntawm 50mm feem ntau yog xaiv. Kev nce qib ntawm cov electrode hauv kev ua haujlwm yog nyob ntawm qhov tseeb tam sim no ceev. Rau ntsug electrodes, electrode txuas ntxiv yuav tsum tau txiav txim siab thaum qhov ceev nce mus txog 0.8A / cm2.
Raws li kev siv hluav taws xob nce ntxiv, qhov ceev tam sim no ntawm lub tshuab hluav taws xob nrog lub hnub nyoog ntev dua (ntau dua 4 xyoos) nce. Yog tias cov electrode tsis npaj mus txuas ntxiv, qhov ceev tam sim no yuav tsum tau tswj ntawm tus nqi qis dua. Thaum qhov ceev tam sim no ntawm molybdenum electrode qis dua 0.6A/cm2, lub electrode yuav luag tsis noj.
Lub resistivity ntawm cov iav tsis kam xws li dej qab zib iav yog tsawg dua 15Ω·cm, yog li nws nyuaj rau cov electrode los tswj qhov ceev tam sim no hauv qab no 0.6a/c·m2. Vim nws tsis tshua muaj viscosity thiab tsis tshua muaj zog, 75mm electrodes feem ntau siv. Tsis tas li ntawd, cov electrodes yuav tsim ntau yam kev poob thaum lub sijhawm ua haujlwm, yog li cov electrodes yuav tsum tau nqa mus. Los ntawm kev xav ntawm electrode kev khiav hauj lwm cov nqi, phaj electrodes haus tsawg dua thiab yog li tsim nyog rau melting dej qab zib thiab txiv qaub iav.
