Definitions

  • the present invention relates to a device for supplying electrical energy and for mechanically supporting the electrodes, an electric arc furnace intended to equip a steelworks.
  • the device according to the invention allows a simpler manufacture than for these known devices, as well as a reduction in the electrical reactance of this part of the oven, which makes it possible to have, for the same power drawn from the network, a significant increase. of the power of the arcs.
  • It is characterized in that it is equipped with non-magnetic metal electrode-carrying arms, the upstream end of which serves as a contact area for the current supply cables.
  • the metal used is stainless steel.
  • the brar are constructed so as to present, on the current path, no sharp angle as well in their section as in their length.
  • each of the three vertical masts (1,2,3) carries, in a conventional manner, a wider support piece (4,5,6), provided with a part electrically insulating 7.
  • each support piece (4,5,6) carries a horizontal arm (8,9,10) made of stainless steel, the upstream end (11,12) of which serves as a contact pad for the cables 13 for supplying the current, and the downstream end of which is attached to the clamps (14, 15, 16) intended to grip the electrodes.
  • the arms (8, 9, 10) are constructed so as to present, on the path of the current, no sharp angle. Their section is circular and they are, in the direction of the length, either completely rectilinear, or presenting curves in S.
  • Figure 1 shows one of the two arms, such as arm 8, which is not framed by the other two.
  • arm 8 is rectilinear and its support member (1,4) arrives at the lower part of the associated clamp 14.
  • Figure 2 shows the "central" arm 9, which is framed by the other two (8,10, Figure 3).
  • its support member (2,5) arrives, in a conventional manner, at a level situated above that of the lower part of the associated clamp 15.
  • the mast 2 is therefore more. higher than the other two.
  • the three clamps (14,15,16) being preferably at the same level, the arm 9 has a soft curvature, S-shaped as shown, so that its downstream part is at the same level as the others.
  • non-magnetic metal is essential because these metals have a "skin effect" much less than that presented by non-magnetic metals, such than ordinary steel, for example.
  • the "Kelvin skin” is in fact about thirty times thicker for stainless steel than for ordinary steel.
  • stainless steel leads to dimensions of electrode holder arms which are especially well suited to the desired layouts for electric ovens; this metall is therefore preferred for carrying out the invention.
