HOLLOW ELECTRODE ASSEMBLY OF CARBON HAVING DENSED GRAPHITE JUNCTION NIPPLE

摘要

A hollow electrode assembly of industrial carbon comprises coaxially sequential electrode members with a central through-bore lined by an inner tube of carbon in each member. Each two sequential electrode members are rigidly joined with each other by a nipple, preferably of double-conical shape, which enters into respective socket recesses in the adjacent electrode members. The inner tubes of the electrode members are rigidly and gastightly connected with each other. Preferably, the connecting nipple is also lined with an inner tube which enters into a close telescoping seating relation with the adjacent ends of the respective electrode members.
