<p>In an arc furnace, it is intended to prevent contact of the electrodes with the cover in the region of the electrode ducts during tipping of the furnace vessel, in a manner which is simple to manufacture and to carry out. The gantry (11) is arranged such that it is resistant to tipping and can move in the horizontal direction with an axis of rotation (13) at a distance from a tipping plane. A tipping movement of the furnace vessel (5) can be converted into a rotational movement of the gantry (11) via a coupling device (37, 39, 41) between the furnace vessel (5) and the gantry (11) such that, during tipping of the furnace vessel (5), the sections of the electrodes (23, 25 and 27) engaging in the electrode ducts (31) are driven with the movement in the horizontal direction, essentially corresponding to the horizontal displacement of the electrode ducts (31). Coupling devices which act both mechanically as well as electrically can easily be used. For example, even arc furnaces which are already installed can be reequipped in a simple manner with a coupling device according to the invention. <IMAGE></p> |
