Graph kaw electrode yog cov khoom siv uas tuaj yeem tiv taus ntau qhov kub txog 3000 degrees Celsius yam tsis tau deformed thiab melted. Yog li, lawv raug xaiv los ua cov hlau hauv hluav taws kub arc rauv (EAF) thiab chav dej sov (lf).
Nws ua haujlwm li cas hauv kev coj ua? Thaum hluav taws xob tam sim no dhau los ntawm cov lus qhia hluav taws xob tsim hluav taws xob arc uas tsim kom muaj cua sov thiab melts cov hlau. Cov dej kub siab kuj thiab cov cua sov kev poob siab ua rau nws ua nws cov khoom siv tsis tau rau statmaking.
