Dab tsi yog graphite electrode rau melting txheej txheem?

Ib graphite electrode rau cov txheej txheem melting yog ib qho tshwj xeeb tiv thaiv siv hauv cov hluav taws xob ua kom sov siab los ua kom muaj cua sov Graphite yog cov khoom siv uas xav tau rau cov hluav taws xob no vim nws qhov kev ua kom muaj hluav taws xob tshwj xeeb, siab thermal stability, thiab kuj ua rau cua sov. Thaum muaj hluav taws xob txuas ntxiv los ntawm graphite elc (hauv EAFS) lossis muaj cov cua sov ntau dua (5,432 degree)

Graphite hluav taws xob siv hauv cov txheej txheem melting tuaj hauv ntau qib, suav nrog RP (lub zog loj), txhua qhov zoo rau cov zog sib txawv thiab cov cua sov. Kev xaiv ntawm electrode nyob ntawm qhov xwm txheej xws li lub cub tawg, cov khoom siv tau melted melting ceev. Piv txwv li, UHP graphite hluav taws xob tau siv nyob rau hauv lub siab niaj hnub- effection EAFs thiab cov kev coj hluav taws xob thiab electrode hnav yog qhov tseem ceeb.

Thaum lub sijhawm ua haujlwm, graphite cov ntawv raug rau cov neeg kho tshuab huab cua, thermal, thiab kev caij tsheb kauj vab, thermal cycling, thiab hnav los ntawm hluav taws xob arc. Raws li qhov tshwm sim, lawv maj mam yaig thiab yuav tsum tau saib xyuas ib txwm thiab hloov los kom muaj kev ua kom sov. Siab -}} zoo graphite cov ntawv pov thawj ruaj khov, txo cov khoom siv hluav taws xob, thiab txhim kho cov khoom lag luam kom muaj txiaj ntsig. Kev nce qib hauv electrode kev tsim khoom, xws li txhim kho cov khoom siv ua purity thiab kev ua tau zoo tshaj plaws hauv kev lag luam los ntawm kev lag luam los ntawm steel ntau lawm hlau rau hlau tshwj xeeb.
