Definitions

  • the invention relates to a method and an apparatus for emptying metallurgical melting vessels by tilting, such as, for example, electric arc melting furnaces and electrical row melting furnaces, with an underframe frame resting on a foundation, a tilting device, a closable tap hole arranged in the furnace floor and one on the side of the furnace arranged slag overflow edge.
  • these metallurgical melting vessels are usually equipped with a tilting device, by means of which the entire melting vessel is brought into an oblique position from its originally horizontal basic position.
  • the tilting cradle of the furnace is designed in the form of a circular arc and is supported on rollers which are rotatably mounted in a frame resting on the furnace foundation. To stabilize the furnace, it is additionally supported by at least one hydraulic tilt cylinder. Due to the described design of the melting vessel, it can be tilted in both directions for slagging and steel tapping, with the center point of the scrap feed chute also being the center of rotation of the melting vessel during the tilting movement. Furthermore, a cam is attached to the tilting cradle mounted on the rollers in a defined area, which, when a tilting area is exceeded, abuts on the scraper side on the roller and slides upwards along it.
  • a disadvantage of these known designs of the tilting devices with an underframe frame that is supported on cradles is that the position of the tap opening and slag overflow edge changes greatly during tilting and leads, for example, to large distances between the melting vessel and the tap opening and thus the nitrogen content during tapping favored.
  • the tilting cylinders that stabilize the furnace mounted on rollers are adversely impacted by the shocks and vibrations caused during the charging and melting process during furnace operation.
  • the object of the invention is, based on the known prior art, to provide a method and a device for emptying metallurgical melting vessels by tilting, by means of which the disadvantages described, in particular the shifting of the position of the opening and the slag overflow edge during the tilting process, are largely avoided.
  • one side of the lower furnace frame of the melting vessel is raised from its foundation supports, on which the lower furnace frame rests in the basic position of the melting vessel, and is pivoted about the opposite foundation supports as a fulcrum or axis of rotation.
  • the foundation supports which are arranged at the upper end of columnar foundations, are bowl-shaped. In this bowl-shaped foundation supports, the lower furnace frame is supported with its support elements which are rotatable in the foundation supports.
  • the columnar foundations are assigned tilting cylinders, which make it possible to lift any single side of the lower furnace frame or the entire melting vessel, with a tilting movement (rotary movement) over the respective opposite foundation supports as the pivot point or axis of rotation.
  • the tap opening and the slag overflow are in the immediate vicinity Arranged near this axis of rotation, so that during the tilting process advantageously no or only an insignificant ' change in the position of the tap opening and slag overflow edge takes place.
  • the tap opening and slag overflow edge are arranged on the melting vessel in such a way that both slag removal and emptying of the melt are possible by a tilting movement to only one side.
  • the tap opening is advantageously arranged such that it is in the basic position of the melting vessel above the level of the remaining liquid sump remaining after the tap.
  • the tilting cylinders which have to support part of the furnace weight during the tilting process and are of correspondingly large dimensions, are completely relieved of load when the melting vessel is in the basic position, in which the melting vessel rests on all foundation supports.
  • Fig. 1 is a melting vessel according to the invention in its
  • Fig. 2 shows a melting vessel corresponding to Fig. 1 for
  • a melting vessel 1 according to the invention is shown in its basic position.
  • the melting vessel 1 rests here with the support elements 8 of the sub-furnace 2 on shell-shaped foundation supports 7, which form the upper end of pillar-shaped foundations 6.
  • a tilt cylinder 3 which is completely relieved in the basic position shown, since the lower furnace frame 2 was resting on all the existing Fudamentauf 7.
  • the foundations 6 are arranged with their foundation support 7 so that they are as close as possible to the
  • the melting vessel 1 is lifted or tilted for lifting off by lifting the lower furnace frame 2 by means of the tilt cylinders 3 arranged on the right. While the right part of the furnace frame 2 with the tap opening 4 stands out from the foundation supports, the left part of the furnace frame 2 rotates with its support elements 8 within the left-hand foundation supports 7, which thus represent the pivot point or the axis of rotation.
  • the slag overflow edge 5 hardly changes its position with respect to the starting position in the basic position according to FIG. 1 due to the tilting process shown, since the slag overflow edge 5 is in the immediate vicinity the axis of rotation of the foundation supports 7 is arranged.
  • FIG. 3 the tilt position to the opposite side is shown in FIG. 2.
  • the left side of the lower furnace frame 2 is raised in order to discharge the melt from the melting vessel 1 via the tap opening 4.
  • the tap opening 4 practically coincides with the axis of rotation of the foundation supports 7, the position of the tap opening 4 is hardly changed by the tilting movement.
  • the tilting is shown on two opposite sides.
  • the design of the tilting device according to the invention also allows the tilting process to be carried out on any side, which can be advantageous, for example, for repairs and maintenance work.
