<p>1. A furnace vessel for a d.c. arc furnace, comprising a contact device which is arranged in the central area of the vessel base and which serves to discharge the anode current, where this contact device comprises a plurality of metallic base electrode pins which extend in parallel to the vessel axis and are retained in refractory material, and of a cooled current outlet which is arranged below the furnace vessel, characterized in that each base electrode pin (4) is detachably fixed to the vessel (5) by means of a retaining device (6, 7, 16), is individually insulated from the vessel (5), extends through perforated refractory bricks (2) so as to be insertable and extractable, and is individually connected to the cooled current outlet (14).</p> |
