<p>Axially Movable Electrode Holder for Use in Electric Steel Production An axially movable electrode holder of metal, particularly copper or copper basealloy, for active parts of consumable or slowly consumable material, which are attachable by means of a threaded nipple or a similar means. The electrode holder comprises a cooling unit with a supply and a return duct, and has at least partly, preferably in its lower region, a protective coating and a contact arrangement on its sheath area by which the electrode holder may be connected to a current supply. The electrode holder further comprises a number of removably mounted electrical and/or mechanical contact moldings of pressure-resistant material extending over a length of the electrode holder which corresponds to at least a part of the length of an allowable tip consumption. The electrode holder, which is intended for use in the electric steel production, is characterized by a high reliability in service, good manoeuvrability, and good electrical properties.</p> |
