I-Hardfacing WeldingI-Electrode
Okujwayelekile: DIN 8555 (E7-UM-250-KPR)
Inombolo yohlobo: TY-C BMC
Ukucaciswa nokusetshenziswa:
· I-electrode ye-SMAW yokutakula eyisisekelo ehlanganisiwe
· Isakhiwo esigcwele se-austenite.Ukusebenza kanzima nokuqina okuphezulu kakhulu.
· Ilungele ukumbozwa ezingxenyeni ezingaphansi kwengcindezi ephezulu kanye nokushaqeka kuhlanganiswe nokuhuzuka.Okungaphezulu kungenziwa ngensimbi ye-ferritic kanye ne-austenitic hard Mn-steel futhi amalunga ensimbi eqinile ye-Mn angashiselwa.
· Izinkambu ezisetshenziswa kakhulu zisembonini yezimayini nosimende, indawo yokuwela ujantshi, amaphampu e-dredge, ama-pistons omshini wokunyathelisa nge-hydraulic, ingxenye ye-crusher enomthelela omkhulu ngamaminerali athambile.
