Definitions

  • the invention relates to a channel arrangement for draining melted Metal from a melting furnace.
  • racking Draining the molten metal from a furnace, e.g. out a blast furnace or cupola furnace is referred to in technical terms as racking.
  • the liquid metal including the liquid slag led out of the melting furnace via a channel made of refractory material.
  • the Channel is in a strong lining made of refractory refractory bricks arranged, which is also called delivery.
  • the gutter is then taken out of service and repaired. The so far The usual course of action is to identify the worn areas Break out. This is done partly mechanically, partly manually using a jackhammer. Then the gutter is removed from the inside and the one to be restored Area using a potting compound made of refractory material poured out.
  • the object of the invention is therefore based on the prior art based on a channel arrangement for draining molten metal to create from a melting furnace in which the time for preparation a worn gutter is significantly reduced and the total one Allows cost reduction.
  • the channel arrangement then comprises a channel with two side walls and a gutter bottom made of refractory material, which within a Formwork pan is arranged.
  • the side formwork walls are with a cross movable sliding wall. Between the curtain walls and the Side walls, a receiving space is provided with a curable Refractory is fillable.
  • the channel arrangement according to the invention enables a strong rationalization preparation of the gutter.
  • Core idea of the invention is already behind the side walls of an operational gutter, the replacement side walls to hold. These are due to the filling of the recording room created with the refractory to make it operational Use the gutter or its side walls as a shape.
  • a first channel is cast conventionally. Here serve the push walls of the side formwork. After the The push walls become the push walls from the side walls of the channel to the lateral formwork walls of the formwork pan shifted. Then the created between the push walls and the side walls of the channel Recording room can be filled with a refractory.
  • the gutter in operation As soon as the gutter in operation is so worn that a Preparation is necessary, it is taken out of operation and released made. The floor area is exposed, then the remaining part of the side walls together with those in the recording room available spare side walls to the front pushed. Then the channel bottom is filled with refractory just like the recording room created behind the replacement side walls.
  • Temperature-resistant cast concrete, thixotropic are used as refractory Casting compounds, low-cement concrete or ultra-low cement concrete as well as ramming and Spray compounds for use. Also dry masses and so-called backfill masses can be installed.
  • Channel arrangement also leads to a significant reduction of the need for refractories, since already worn material in the The unit remains and when the new or repair delivery is used as a casing serves. This can further reduce costs.
  • the channel within the formwork pan is arranged on a base plate. This measure leads to a further improvement in the work to expose the bottom Area of the side walls and moving the replacement side walls the bottom plate.
  • the push walls are displaceable according to claim 3 by means of an adjustment mechanism.
  • Different systems can be implemented. For example, it is possible the execution by means of cylinders and cylinder rods or adjusting spindles with threads.
  • the inner surfaces of the formwork pan with an insulating liner Mistake lends itself in particular below the base plate is insulated, for example from refractory refractory bricks, to arrange.
  • Figure 1 shows a channel arrangement 1 for draining melted Metal from a melting furnace, not shown.
  • the channel arrangement 1 comprises in the middle area a cast from fireproof material Channel 2, which is arranged within a formwork pan 3 made of steel.
  • a formwork pan 3 made of steel.
  • Movable push walls 7, 8 form here the lateral formwork for the side walls 4, 5, a molded body 9 with side parts 10 inclined to the vertical in the upper region between the push walls 7, 8 is arranged and for the necessary contouring the gutter 2 provides.
  • the channel 2 is on a refractory base plate 11 worn within the formwork pan 3.
  • the formwork pan 3 is dimensioned larger than that in its transverse extent Channel 2, being between the side walls 4, 5 of the channel 2 and the side Formwork walls 12, 13 of the formwork tub 3, a receiving space 14 is provided is.
  • the inner surfaces 15 of the formwork tray 3 facing the channel 2 are additionally provided with an insulating lining 16. Not shown here but an additional insulating lining is also useful in practice under the base plate 11, for example made of firebricks.
  • the thrust walls 7, 8 are removed by means of a the adjustment mechanisms 17 penetrating the formwork walls 12, 13 to the outside the formwork walls 12, 13 shifted ( Figure 2).
  • the now between the Thrust walls 7, 8 and the side walls 4, 5 of the channel 2 existing receiving space 14 is also poured out with a refractory material 18 (FIG 3).
  • the receiving space 14 is released again and can be in one be poured again with a refractory 23.
  • a new channel floor 24 is poured, which is due to the existing Replacement side walls 21, 22 is also possible without molded body 9 ( Figure 8).
