RP GRAPHITE ELECTRODE - Kev Ua Hluav Taws Xob Zoo, Kev Siv Hluav Taws Xob Tsawg
PIAV TXOG
Cov electrodes graphite RP, uas yog cov kab graphite uas raug pwm, yog siv ua cov khoom siv hluav taws xob kub siab rau cov cub tawg hluav taws xob. Cov electrodes graphite fais fab ib txwm muaj nrog qhov ceev tam sim no tsawg dua 17 A / cm2. Qhov zoo ntawm cov electrode graphite txiav txim siab qhov tsim tau thiab tus nqi ntawm EAF steelmaking.
Ua ib lub chaw tsim khoom, peb kuj muab cov hluav taws xob graphite electrodes UHP qib thiab cov hluav taws xob graphite electrodes HP qib rau cov cub hluav taws xob arc muaj zog heev lossis muaj zog heev. Ntxiv rau kev siv rau hauv cov cub hluav taws xob arc, cov hluav taws xob graphite electrodes kuj tseem siv dav hauv cov cub hluav taws xob arc thiab Ladle furnaces.
NTAUB NTAWV
Muaj peev xwm nqa tau tam sim no.
Zoo heev tsis kam rau kev tawg.
Muaj kev tiv thaiv zoo rau oxidation thiab thermal shock.
