Siv dav hauv kev lag luam
- Rau Electric arc rauv steel ua
- Rau Yellow phosphorus rauv
- Thov rau Industrial silicon rauv los yog melting tooj liab.
- Siv rau Refine steel hauv ladle furnaces thiab hauv lwm cov txheej txheem smelting
Yuav ua li cas xaiv qhov haum Graphite Electrode
Thaum nws los txog rau xaiv txoj cai graphite electrode, muaj ntau yam los xav txog.
- Ua ntej, qhov zoo ntawm cov electrode yog qhov tseem ceeb.Lub tshuab hluav taws xob zoo yuav muaj cov qauv zoo sib xws, uas txhais tau tias nws tsis tshua muaj kev tawg thiab tawg.
- Qhov thib ob, qhov loj ntawm cov electrode yuav tsum raug xaiv raws li EAF lub zog ntsuas, nrog rau cov cub tawg loj dua yuav tsum muaj cov hluav taws xob loj dua.
- Thib peb, hom electrode yuav tsum raug xaiv raws li qib steel, kev ua haujlwm tsis zoo, thiab tsim lub cub tawg.Piv txwv li, UHP (Ultra High Power) electrode yog qhov zoo dua rau lub tshuab hluav taws xob siab, thaum HP (High Power) electrode yog tsim rau nruab nrab lub tshuab hluav taws xob.
