Graphite electrodes yog siv nyob rau hauv hluav taws xob arc furnaces (EAF) rau ntau yam tseem ceeb:
- High Electrical Conductivity: Graphite muaj cov khoom siv hluav taws xob zoo heev, uas tso cai rau kev sib kis tau zoo ntawm cov hluav taws xob tam sim no. Qhov no yog qhov tseem ceeb rau kev tsim kom muaj qhov kub thiab txias uas xav tau los yaj cov hlau thiab lwm yam khoom hauv EAF.
- Muaj peev xwm tiv taus qhov kub thiab txias: EAFs ua haujlwm ntawm qhov kub siab heev, feem ntau tshaj 1,600 degrees Celsius (kwv yees 2,912 degrees Fahrenheit). Graphite electrodes tuaj yeem tswj hwm lawv cov qauv kev ncaj ncees thiab kev ua haujlwm raws li cov xwm txheej no, ua rau lawv tsim nyog rau daim ntawv thov no.
- Tsawg hluav taws xob tsis kam: Graphite electrodes muaj hluav taws xob tsis tshua muaj hluav taws xob, uas pab txo qis zog thaum lub sij hawm melting txheej txheem. Qhov no ua rau muaj kev siv zog ntau dua thiab txo cov nqi ua haujlwm.
- Thermal stability: Graphite tuaj yeem tiv taus qhov kub hloov pauv sai thiab thermal shock yam tsis muaj degrading, uas yog qhov tseem ceeb rau qhov chaw nyob hauv ib puag ncig EAF.
- Tshuaj tiv thaiv: Graphite tiv taus oxidation thiab lwm yam tshuaj lom neeg cov tshuaj tiv thaiv uas tuaj yeem tshwm sim hauv qhov cub cua sov, ua kom muaj kev ruaj khov thiab ua haujlwm ntev thaum ua haujlwm.
- Ntau yam: Graphite electrodes tuaj yeem tsim nyob rau hauv ntau qib, xws li UHP (Ultra-High Power), HP (High Power), thiab RP (Regular Power), tso cai rau kev xaiv raws li cov kev cai tshwj xeeb ntawm EAF kev ua haujlwm.
- Siab Mechanical Strength: Cov neeg kho tshuab lub zog ntawm graphite electrodes tso cai rau lawv los tswj cov kev ntxhov siab uas tshwm sim thaum lub sij hawm melting thiab refining txheej txheem hauv EAF.
- Yooj yim ntawm kev tsim khoom thiab hloov: Graphite electrodes tuaj yeem tsim nyob rau hauv cov duab sib txawv thiab qhov ntau thiab tsawg raws li cov qauv tsim tshwj xeeb rau lub cub tawg, thiab lawv cov kev hloov pauv ncaj qha, txo qis qis qis thaum ua haujlwm.
