HP GRAPHITE ELECTRODES - qhov loj ntawm 200 mm txog 600 mm
HP GRAPHITE ELECTRODES - qhov loj ntawm 200 mm txog 600 mm
PIAV TXOG
HP graphite electrode yog lub ntsiab lus tseem ceeb rau kev siv hluav taws xob arc furnaces steelmaking. Nws yog ua los ntawm roj av coke, koob coke, thee pitch thiab tsim los ntawm ntau yam txheej txheem tsim khoom nruj. Cov kab hluav taws xob siab ntxig los ntawm qhov chaw graphite electrode hauv lub cev cub. Qhov no yuav tso tawm lub zog hluav taws xob hauv lub cub tawg arc los ua kom lub cub tawg sov.
Qhov kev thov rau cov electrodes loj dua tau nce ntxiv thaum qhov loj ntawm EAF lub cub tawg loj zuj zus. Cov electrodes graphite nrog lub cheeb ntawm 500 mm lossis 600 mm tau dhau los ua nrov zuj zus nyob rau xyoo tas los no.
