FIELD: metallurgy. ^ SUBSTANCE: in electrode column, containing at least two electrodes, interconnected by ends by nipple, metallic ring is additionally mounted between end surfaces of electrodes - plate 0,06-0,27 mm thick. Inner diameter of plate ring is taken greater than maximal diameter of nipple. Outer diameter of ring does not exceed electrode diameter. Outer diameter can equal the diameter of ends of connected electrodes in lower portion of work of electrode column in furnace. In that case on end surface free from ring current-conductive material is placed. As metal for ring, hard-drawn copper or aluminum are recommended. ^ EFFECT: excluded reasons for destruction of electrodes. ^ 5 cl, 8 dwg |
