Definitions

  • the invention relates to a tapping channel for an iron smelter, as they are e.g. is used on the blast furnace for tapping the pig iron.
  • Tapping channels for molten iron have been known for a long time. They exist essentially an outer support structure (such as a metallic one) Trough) with a refractory lining.
  • the lining is usually made from a permanent feed, e.g. is made of refractory stones that are inserted directly into the metallic trough, and one Wear lining made of a refractory casting compound in which the receiving channel for which approximately 1500 ° C warm iron melt is formed.
  • the tapping channel is exposed to heavy loads.
  • Corresponding the refractory lining often has to be repaired or replaced.
  • Cooling can improve.
  • coolant usually cooling water
  • EP-A-0060239 proposed the outer Form support structure as a double-walled metallic trough, through which Interior compressed air is passed as a coolant.
  • a double-walled metallic trough through which Interior compressed air is passed as a coolant.
  • forced cooling includes forced cooling
  • air has a far lower effectiveness. It is also one Compressed air cooling is very energy intensive.
  • Another disadvantage is that the double-walled metal trough requires a relatively large amount of production requires.
  • EP-A-0143971 proposes to the side of the pouring channel, inside the refractory lining, box-shaped cooling elements or To provide cooling pipes which are connected to a cooling water circuit.
  • the wear lining is in front of the cooling elements a copper plate with thermo elements arranged. The latter are in one Control circuit connected, which is exceeded when a predetermined Maximum temperature or rate of temperature rise Water supply blocks and the cooling elements to a compressed air network for the purpose Emergency cooling connects.
  • the permanent feed be good conductive layer of graphite, semigraphite or silicon carbide stones disguise, which is crossed by cooling pipes through which a liquid Coolant is passed.
  • This highly conductive layer is replaced by the liquid Coolant strongly cooled so that the molten iron which cracks up to penetrates this outer cooling layer, solidifies immediately.
  • the graphite, Semigraphite or silicon carbide stones also by copper, iron or Cast iron plates could replace and that the cooling tubes in a good could embed conductive material.
  • the present invention has for its object a to create a forced cooling trough with a copper lining, at the risk of coolant leakage into the molten iron is greatly reduced.
  • a tapping gutter according to claim 1 is a possible solution to this Task.
  • Such a tapping channel comprises an outer support structure with a Refractory lining in which a channel for the iron smelting is formed.
  • a massive, forcibly cooled by a cooling device Copper lining surrounds the refractory lining in the support structure. she has the function of cooling the inner refractory lining and thereby to extend their service life. It also protects the outer support structure against overheating.
  • this copper liner has solid ribs, which consists of a solid copper base body Protect the refractory lining. Of course, these ribs improve the cooling effect in the refractory lining and thus its service life.
  • the main function of these ribs is the massive copper Base body when iron melt penetrates into the Protect refractory lining.
  • This protective function is mainly in that the penetrated iron melt through the ribs up cooled to solidify and is therefore stopped before it starts comes into contact with the solid base body made of copper. This will Overheating cracks in the solid copper base body avoided, and thus reduces the risk of coolant leaking into the molten iron. It stays It should be noted that there is contact between the molten iron and the rib cause local overheating or partial melting of the rib can, which usually does not have a significant negative impact has the actual base body made of copper.
  • the refractory lining is advantageous, at least in the area of the ribs poured onto the copper lining. This is the heat transfer between the refractory lining and the copper lining in the area of the Ribs improved. Cavities and crevices through which the iron melt penetrate to the copper lining are avoided more effectively.
  • the copper lining is preferably made of solid copper plates trained, which are advantageously continuously cast.
  • a longitudinal section of the Tapping channel can for example consist of a base plate and two side plates are made of copper.
  • the cooling device comprises cooling channels in the copper liner, each of the cooling channels each having a rib is covered. Due to the location of the cooling channels under the massive fins the risk of coolant leaking into the iron melt is further reduced.
  • the fins and cooling channels preferably run parallel to Longitudinal direction of the tapping gutter. This reduces the number and Length of the external connections between the cooling channels. Still allowed this arrangement with continuously cast copper plates through the cooling channels Inserts in a continuous casting mold as through channels in the casting direction form, and / or the ribs by battlements in the continuous casting mold train.
  • Another solution to the given task can be that the cooling device, instead of cooling channels in the copper lining, one external cooling circuit, which the copper lining from the outside, i.e. of the cools the back structure facing back.
  • This solution too enables a reduction in the risk of coolant leakage into the Molten iron.
  • the massive copper lining made of copper does indeed an extremely effective shield, which is a coincidence of coolant and effectively prevents molten iron. Small cracks in the massive Copper lining is hardly a danger here.
  • Such an external cooling circuit can, for example, a spray device for Spray the back of the copper liner with a coolant include. It should be noted that when meeting with a Molten iron, finely sprayed water e.g. a far less danger represents, as a compact jet of water from a leak in one Cooling channel emerges. To cool the copper lining through the To improve the spray device, the rear is advantageous by furrows increased.

With the reference numerals 28 and 30 in Figure 1, the seams between the side plates 22, 24 and Designated bottom plate 26. Since the length of the individual copper plates 22, 24, 26 is usually much shorter than the length of the trough of course, a plurality of side plates 22, 24, or bottom plates 26 are lined up around the support trough 10 over its entire length undress.

  • a no less important function of the ribs 32 consists in a local breakthrough of the molten iron 14 into the Permanent feed 18 to cool the molten iron to solidify before using it comes into contact with the actual base body made of copper and deep inside Overheating cracks caused. It should be noted that contact between a rib 32 and the molten iron, local overheating, or even a partial meltdown that can cause rib 32, as a rule however, no major negative effects on the actual one Has base body made of copper.
