ELEKTRODE FOR SMELTEELEKTROLYSE.

摘要

An electrode for fusion electrolysis comprising an upper portion (5) of metal and a replaceable lower portion (6) of self-consuming or of slowly self-consuming material which are interconnected by a screw-nipple (1) or the like, whereby the upper portion may have a cooling device with a feed duct (2) and a return duct (3) and the upper portion (5) has at least partially and preferably in its lower region a protective covering, whereby this covering is a detachably surmounted sheath (4) of mechanically resistant material, which is electrically conductive. The sheath can be sub-divided into individual segments, while the design of screw-mounted units with internal recesses for the acceptance of resilient, electrically conductive materials reveals especially favorable properties.
