daim ntawv thov
(1) Rau steel ua hauv EAF / LF
Graphite electrode feem ntau yog siv rau hauv hluav taws xob arc rauv rau steel smelting.Thaum graphite electrode ua haujlwm hauv EAF, qhov tam sim no yuav raug qhia los ntawm graphite electrode rau hauv lub cub tawg, thiab yuav muaj cua sov qhov chaw uas yog tsim los ntawm hluav taws xob arc ntawm electrode kawg thiab rauv nqi rau smelting.
(2) Kev tsim cov xim hlau silicon thiab daj phosphorus hauv submerged arc rauv
Qee cov pa roj carbon electrode nrog loj loj (piv txwv li.700mm-1400mm) yog siv los ua cov hlau silicon thiab daj phosphorus hauv submerged arc rauv.Qhov qis ntawm cov pa roj carbon electrode yog faus rau hauv tus nqi, tsim ib qho arc nyob rau hauv cov txheej txheem, cov khoom yuav smelted los ntawm lub tshav kub zog generated los ntawm cov kuj ntawm tus nqi.Piv txwv li, kwv yees li 100kg ntawm graphite electrode yog siv rau 1 tuj ntawm cov hlau silicon.
(3) Rau kev tsim corundum hauv hluav taws xob rauv
(4) Siv rau kev ua cov khoom tshwj xeeb zoo li graphite
Qhov khoob ntawm graphite electrode kuj yog siv los ua ntau yam tshwj xeeb zoo li graphite khoom
