Definitions

  • the invention relates to a tipping trough for guiding molten material, in particular mineral spinnable materials, such as slag, with a trough-shaped trough body which can be pivoted about a tipping axis by means of a swivel drive from a normal operating position to an emergency operating position and vice versa, and has spouts at opposite ends the end spouts has a point of impact for a jet of molten material.
  • molten material in particular mineral spinnable materials, such as slag
  • a tipping channel is known for example from DE-C - 628 234. It serves to direct the molten material hitting the tipping channel in one jet in different directions and thus into different vessels.
  • the point of impact of the beam is subject to a particularly high thermal load in tipping channels.
  • the impact of the jet also causes erosion of the refractory lining of the known channel at the point of impact and thus contamination of the melt by refractory material.
  • the fireproof lining must be replaced at the point of impact at short intervals. This is particularly the case when the jet of molten material emerges from a metallurgical vessel approximately horizontally, since one is then forced to arrange the longitudinal axis of the tipping channel approximately transversely to the plane of the jet.
  • the invention aims to avoid these disadvantages and Difficulties and the task is to create a tipping channel of the type described above, in which the point of impact of the jet has approximately the same lifespan as the rest of the trough and in the operating position, ie in the mainly used tilting position, a deflection of the pouring jet is avoided from its level.
  • the trough-shaped channel body is formed by two channel parts with their longitudinal axes forming an angle 0 ⁇ Lf ⁇ 180 °, preferably an approximately right angle, the bottom of a first channel part being arranged at a lower level than the bottom of the second channel part is, the point of impact of the jet at the first channel part is provided close to the junction with the second channel part, and the vertical center plane of the first channel part is in the downward inclined normal operating position of the first channel part in the plane formed by the beam.
  • a particularly simple design is characterized in that the second channel part is arranged with its longitudinal axis parallel to the tilt axis.
  • both channel parts form an acute angle with their longitudinal axes with the tilt axis, preferably an angle of 45 °, the tilt axis in the region of the mouth of the first channel part is arranged in the second channel part.
  • the two channel parts keep each other about the equilibrium about the equilibrium, so that the swivel drive only has to overcome the moment of inertia of the tilting channel about the tilting axis when pivoting or to hold the tilting channel securely in the different positions.
  • the first channel part is preferably arranged rotated about its longitudinal axis with respect to the second channel part.
  • a simple to produce embodiment is characterized in that the channel parts have a V-shaped cross section standing at the tip when the melt flows and are each formed by two side walls which are at the same angle to one another, preferably at right angles to one another, one side wall of the second gutter part lying at a higher level merges into the upper edge of a side wall of the first gutter part.
  • a side wall of the second channel part which is at a higher level, merges into a wall part higher than a side wall of the first channel part.
  • the side walls are preferably hollow and with provided with water cooling, which has the advantage that a solidified material layer, that is to say an insulation of the same type, is formed on the inner sides of the channel body, which makes brickwork unnecessary and prevents contamination of the molten material by foreign material.
  • FIG. 1 showing a section through an electric furnace, on the spout of which the tipping channel according to the invention is mounted according to a first embodiment.
  • Fig. 2 shows a section along the line II-II of Fig. 1 through the furnace.
  • the tipping trough according to the first embodiment is shown on an enlarged scale in an oblique view in different tilting positions.
  • FIG. 5 illustrates a further embodiment of the tipping channel in a representation analogous to FIG. 3.
  • melt 3 The materials 2 melted in an electric furnace 1 collect as melt 3 at the bottom 4 of the electric furnace 1. As soon as the casting level 5 reaches the lower edge 6 of the tap hole 7, melt 3 flows through the tap hole 7 from the electric furnace 1.
  • melt 3 has impurities at the beginning and, for example must not get into a downstream spinner for spinning the melt.
  • a tipping channel 8 is arranged below the tap hole 7, which has two channel parts 12, 13 including an approximately right angle 11 with their longitudinal axes 9, 10, the Floor 14 of the in The direction of the first channel part 12 emerging from the tap hole 7 is arranged at a lower level than the bottom 16 of the second channel part 13 arranged at right angles thereto and thus approximately at right angles to the plane 17 of the jet 15.
  • the tipping channel 8 is attached to the electric furnace in such a way that the point of impact 18 of the beam lies in the first channel part 12, and so on. near the junction with the second channel part 13.
  • the tipping channel 8 can be pivoted about a tilting axis 19 which is arranged parallel to the second channel part 13 and is mounted on the electric furnace 1 by means of two brackets 20 which are fastened to the furnace jacket 21.
  • both channel parts 12, 13 have a V-shaped cross-section, the side walls 24, 25, 26, 27 of the channel parts 12, 13 each of two hollow at approximately right angles to each other , coolant-permeable plates are formed.
  • the first channel part 12 is arranged rotated about its longitudinal axis 9 with respect to the second channel part 13, the side wall 27 of the second channel part 13 lying at a higher level merging into the upper edge 28 of the side wall 25 of the first channel part 12.
  • the second side wall 26 of the second channel part 13 abuts a wall part 29 that rises above the corresponding side wall 24 of the first channel part 12.
  • the first channel part 12 has a coolant supply connection 30 near its spout 23, so that the coolant flows through this channel part 12 against the direction of flow of the molten material.
  • the coolant then passes into the second channel part 13, from which it exits through the outlet connection 32 arranged on the spout 31 of the second channel part 13.
  • the tilt axis 19 'of the tilt channel 8' is no longer arranged parallel to the second channel part 13, but rather includes an acute angle 35 with the two longitudinal axes 9 and 10 of the channel parts 12, 13, which is approximately Is 45 °. Furthermore, the tilt axis 19 'is not horizontal, as in FIG. 1, but is arranged obliquely in space, and it extends approximately through the center of gravity of the tipping channel 8 '. With this measure, the tipping channel 8 'can be pivoted with little effort.
  • the invention is not limited to the exemplary embodiments shown in the drawing, but can be modified in various ways.
  • the cross section of the channel parts can be rectangular or trapezoidal.
  • the angle which the two gutter parts enclose with one another is advantageously a right angle, but the two gutter parts can also enclose an angle which deviates therefrom. This angle depends on the local conditions, i.e. the available space.
