Abstract

Installation de four électrique à arcs dont le four est monté basculant sur un socle-support. Installation of electric arc furnaces whose oven is pivotally mounted on a support base.

L'installation selon l'invention se caractérise en ce que le fond (13) du four (1) présente une géométrie à profil circulaire dans le plan de basculement π, en ce que le socle-support (6) est conformé, à sa partie supérieure, en berceau (14) dont la concavité épouse la géométrie du fond (13) et en ce que le berceau (14) est équipé d'un jeu de roujeaux de guidage (15) sur lesquels repose le four. De préférence, le profil circulaire du fond (13) est déterminé de façon que l'axe de basculement (17) du four passe par le centre de géométrie (18) des points d'attache (16) des câbles électriques (5) sur les potences d'électrodes (3). The installation according to the invention is characterized in that the bottom (13) of the oven (1) has a profile geometry circular in the tilt plane π, in that the support base (6) is shaped, at its upper part, in cradle (14) whose concavity matches the geometry of the bottom (13) and in that the cradle (14) is equipped with a set of guide rods (15) on which the oven rests. Of preferably, the circular profile of the bottom (13) is determined by so that the tilting axis (17) of the oven passes through the center of geometry (18) of the cable attachment points (16) electrical (5) on the electrode brackets (3).

L'invention assure, par une nouvelle cinématique de basculement selon un simple mouvement de rotation du four autour de l'axe de basculement (17), une réduction du débattement latéral des points d'attache (16) et permet ainsi une diminution de la longuer des câbles électiques (5), donc, entre autres, une réduction de l'impédance de l'installation électrique. The invention ensures, by a new kinematics of tilting with a simple rotational movement of the oven around the tilting axis (17), a reduction in lateral movement of the attachment points (16) and thus allows a decrease in the length of the electric cables (5), therefore, among other things, a reduction in the installation impedance electric.
