Faahfaahinta Alaabta
Electrodes-yadu waxay wataan koronto kuleysa foornooyinka korantada, foornooyinka birta ee ugu badan. Waxa laga sameeyaa kookaha batroolka ka dib marka lagu qaso garoonka batroolka, la soo saaro oo la qaabeeyo, ka dibna lagu dubay si ay u miiraan, ka dibna graphitized iyada oo lagu kululeynayo heerkulka (3000 ° C) kaas oo u beddelaya kaarboon graphite. Waxay ku kala duwanaan karaan cabbir ahaan ilaa 11 fuudh. dheer iyo 30 inji dhexroor ah.
Isticmaalka
- 01 Qayb sii kordheysa oo ah birta caalamiga ah ayaa lagu sameeyaa iyadoo la isticmaalayo foornooyin koronto ah
- 02 Foornada arc koronto lafteedu waxay sii fiicnaanaysaa oo waxay samaynaysaa bir badan halkii tan oo elektrode ah
