I-electrode encane yobubanzi begraphite, eklanywe ngobubanzi obusuka ku-75mm kuya ku-225mm, lawa ma-electrode aklanyelwe ngokukhethekile imisebenzi yokuncibilikisa ngokunemba.Kungakhathaliseki ukuthi udinga ukukhiqizwa kwe-calcium carbide, ukucolisiswa kwe-carborundum, noma ukuncibilikiswa kwezinsimbi ezingavamile, kanye nezidingo ze-Ferrosilicon plant refractory.ama-electrode ethu amagraphite amancane ahlinzeka ngesixazululo esifanele.
