ABSTRACT:
A self-baking electrode includes a pressure chamber for receiving electrode paste under pressure. A centrally located conductor supplies electrical current to the paste, and the paste is baked by passage of the electrical current to form an electrode. The electrode is supported by a support band and is advanced past the support band by supplying paste under pressure to the pressure chamber. The pressure chamber is heated to maintain the paste in a softened state.
