Abstract (en)

[origin: EP0043322A2] An electric arc furnace arrangement of which the furnace is tiltably mounted on a supporting base. The arrangement according to the invention is characterised in that the bottom (13) of the furnace (1) has a geometry of circular profile in the plane of tilting pi , in that the supporting base (6) is shaped, in its upper part, as a cradle (14) whose concavity matches the geometry of the bottom (13), and in that the cradle (14) is equipped with a set of guide rollers (15) on which the furnace rests. Preferably, the circular profile of the bottom (13) is so defined that the axis of tilting (17) of the furnace passes through the geometric centre (18) of the points of attachment (16) of the electric cables (5) to suspensions of the electrodes (3). By employing novel kinematics of tilting in accordance with a simple rotating movement of the furnace about the axis of tilting (17), the invention reduces the lateral travel of the points of attachment (16) and thus permits a reduction in the length of the electric cables (5) and hence, inter alia, a reduction of the impedance of the electrical arrangement. <IMAGE>
