Definitions

  • the invention relates to a method and a device for emptying metallurgical melting vessels by tilting, such as electric arc melting furnaces and electric resistance melting furnaces, with on one Foundation overlying furnace frame, a tilting device, one in Oven bottom arranged lockable tap hole and one on the side Oven arranged slag overflow edge.
  • the tilting cradle of the furnace is designed in a circular arc and on rollers supported in a foundation frame resting on the furnace foundation are rotatably mounted. This is used to stabilize the furnace additionally supported by at least one hydraulic tilt cylinder. Due to the described design of the melting vessel, it can be drained off and tiltable to the steel tapping in both directions, with the chute center the scrap feed chute also the roll fulcrum of the Melting vessel during the tilting movement. Furthermore, on the A cam attached to the roller cradle in a defined area that when a tipping area on the waste side is exceeded on the Roller rests and slides up along it.
  • a disadvantage of these known versions of the tilting devices with a on cradle-supporting underframe frame is that the location of Tap opening and slag overflow edge when tipping heavily changed and for example, too large distances between the melting vessel and the tap opening leads and thus favors the nitrogen uptake during tapping.
  • the oven that is stabilized on rollers is stabilized Tilting cylinder during furnace operation with those in the charging and Shocks and vibrations caused by the melting process are adversely affected.
  • US-A-2,268,918 describes an electric arc furnace with one at a time oven support hinged to the side by a column support.
  • the furnace vessel can be tilted by means of a tilt cylinder on the opposite one Attacks the side of the furnace.
  • the object of the invention is a method and an apparatus for emptying metallurgical Specify melting vessels by tilting, by which the disadvantages described, in particular the shift in position of the tap opening and slag overflow edge are largely avoidable during the tipping process.
  • the tiltability according to the invention about each of two opposite axes enables the tap opening and the slag overflow edge to be arranged near the respective tilt axis, so that the location of the openings mentioned little is changed when tipping.
  • one side of the sub-furnace frame of the melting vessel from its foundation supports on which the furnace frame in the The basic position of the melting vessel rests, is raised and around the opposite one Foundation supports pivoted as a fulcrum or axis of rotation.
  • the foundation pads, the top of columnar foundations are arranged, are bowl-shaped. In this bowl-shaped
  • the underframe frame is supported by the foundation supports with its foundation supports rotatable support elements.
  • Tilt cylinders are assigned to the columnar foundations, through which a Lift any single side of the furnace frame or the entire one Melting vessel is possible with a tilting movement (rotary movement) over the respective opposite foundation supports as a fulcrum or axis of rotation.
  • the tap opening is advantageously arranged so that it is in the basic position of the melting vessel above the level of what remains after tapping liquid residual sump is located.
  • the tilt cylinders which during the tilting process are part of the furnace weight have to wear and are appropriately dimensioned during the Basic position of the melting vessel, in which the melting vessel on all foundation supports resting, completely relieved.
  • a melting vessel 1 according to the invention is in its basic position shown.
  • the melting vessel 1 rests here with the support elements 8 of the sub-furnace 2 on shell-shaped foundation supports 7, the form the upper end of column-shaped foundations 6.
  • a tilt cylinder is located in the immediate vicinity of the foundations 6 3, which is completely relieved in the issued basic position, because the furnace frame 2 rests on all existing foundation supports 7.
  • the foundations 6 are arranged with their foundation support 7 so that they are as possible close to the slag overflow edge 5 (left in the drawing figure) and to the Reach tap hole 4 (on the right in the figure).
  • the melting vessel 1 is raised by lifting the lower furnace frame 2 raised by means of the tilt cylinders 3 arranged on the right for slagging or tilted. While the right part of the furnace frame 2 with the Lifting tap hole 4 from the foundation supports, the left part rotates of the furnace frame 2 with its support elements 8 arranged within the left Foundation supports 7, which thus represent the fulcrum or the axis of rotation.
  • the slag overflow edge 5 changed by the tilting process shown almost not their position compared to the starting days in the Basic position according to Fig. 1, since the slag overflow edge 5 in immediate Near the axis of rotation of the foundation pads 7 is arranged.
  • FIG. 3 the tilt position to the opposite side is corresponding to FIG. 2 represents.
  • the left side of the furnace frame 2 is raised to over the Tap hole 4 to drain the melt from the melting vessel 1.
  • the tap hole 4 with the axis of rotation of the foundation pads 7 practically coincides with the position of the tap opening 4 the tilting movement hardly changed.
  • the tiltability to any side can also be used for repairs, for example and maintenance work can be beneficial.
