Ama-electrode e-graphite aphakathi nendawo ayiyona ndlela efanelekile yokuncibilikisa ezimbonini eziningi ezifana ne-calcium carbide, ukucwengwa kwe-carborundum, noma ukuncibilikiswa kwezinsimbi ezingavamile, kanye ne-Ferrosilicon plant refractory. Ukuhlukahluka, lawa ma-electrode anikeza ukusebenza okungenakuqhathaniswa nokusebenza kahle.I-electrode encane yobubanzi be-graphite, ububanzi bobubanzi busuka ku-75mm ukuya ku-225mm
