Habka Wax Soo Saarka ee RP Graphite Electrode
Xakamaynta tayada dusha sare
1.Ciladaha ama godadka waa in aanay ka badnayn laba qaybood oo ka mid ah dusha sare ee graphite electrode, iyo ciladaha ama godadka aan la oggolayn in ay ka badan xogta shaxda hoos ku xusan.
2.There ma jiro dildilaaca transverse on dusha electrode.For crack longitudinal, dhererkiisu waa in aan ka badnayn 5% ee wareegga electrode graphite, width waa in ay dhex 0.3-1.0mm range. noqo mid dayacan
3.The width ee uu bar qallafsan (madow) meesha on dusha electrode graphite waa in aan ka yarayn 1/10 ee wareegga electrode graphite, iyo dhererka bar qallafsan (madow) meesha ka badan 1/3 ee dhererka graphite electrode ah. lama ogola.
