Definitions

  • Cooling element for cooling the refractory lining of a metallurgical furnace (AC, DC)
  • the invention relates to a cooling element for cooling the refractory lining of a metallurgical furnace.
  • cooling elements consist of a copper or a copper alloy, the refractory lining of a metallurgical furnace, such as a shaft furnace, facing plate inside with channels for guiding is provided by coolant.
  • the invention has for its object to provide a cooling element that does not represent such a risk potential with a comparably good cooling effect.
  • the cooling plate, the heat conducting plate and the coolant channel are made of highly thermally conductive material, eg. Example of copper or a copper alloy, wherein the coolant channel advantageously along a narrow side of the heat conducting plate extends.
  • the cooling element may consist of rolled / forged / cast copper plates with a fine-grained texture for good thermal conductivity. According to a proposal of the invention, two such solid copper plates can be welded together (thermally conductively connected) or bent to form a T-profile (also L-profile). The end of the welded copper plate is also welded with a copper tube, as a coolant channel. This copper pipe is cooled with cooling water and, via the connected copper plates, ensures sufficient cooling of the brick lining in the installation area.
  • the dimensions, number per unit area and cooling circuit and the distances of the outwardly projecting from the furnace vessel heat conducting plates are calculated and determined according to the necessary heat dissipation.
  • the cooling elements are equipped with appropriate measuring devices.
  • the cooling elements can be installed at any position of the furnace vessel (ceiling / side wall / floor, horizontal as well as vertical) between lining and vessel steel wall / lid / floor.
  • these coolers in the lower / middle region of the vessel side wall (liquid metal / slag area and abutment area or DC furnace in the gas range) between the refractory lining and the steel sheet of the furnace vessel are arranged.
  • the arrangement of the cooling elements in the abutment region of the lining does not affect the stiffening of the furnace vessel arranged at the location.
  • the cooling elements can be connected to the furnace vessel by screws or the like. Between the cooling elements and the lining a thermally conductive contact mass is tamped.
  • the cooling elements are supplied with cooling water via the externally welded copper tubes.
  • the water-cooled parts of the cooling elements are arranged outside the furnace vessel. In the case of water leaks, therefore, no water will get into the oven and endanger the furnace operation.
  • the cooling elements are connected to several in series, to a cooling circuit. However, the individual positioning is chosen such that if a cooling circuit fails, the adjacent areas continue to remain indirectly cooled.
  • the cooling elements should be connected to closed cooling circuits.
  • the cooling elements can also be connected to it, if the quality of the cooling water and the float content are within the specified tolerances (quality).
  • the advantages that can be achieved by the cooling elements according to the invention can be summarized as follows: Improvement by reaching a completely dry oven vessel. Improved heat dissipation compared to a spray / trickle cooling. Can also be used in areas where the static requirements of the furnace vessel must be maintained. Compared to other systems, only small openings in the furnace vessel are necessary, which has a positive effect on the stability and the coherence of the lower / upper vessel. The amount of heat dissipated through the cooling elements is sufficient to both protect the involved components against destruction and to cool the inner side facing the process to form a self-protection of solidified, cooled or low-reactivity product.
  • the cooling elements are not in direct contact with the process or with the product (slag / metal) and can be combined with other copper cooling systems, which are not located in the statically important areas of the furnace vessel, without any problems.
  • These cooling elements are particularly suitable in hard to reach places on the furnace vessel, especially in Bodenerker a rectangular vessel, where previously was forced to resort to an open spray cooling. They can be used on AC / DC reduction furnaces with a rectangular and round furnace vessel. In the latter especially advantageous because it comes through the nature, shape and mounting position to no impairment of the Ofengefäßstatik / stability.
  • Fig. 1 is a perspective view of the cooling element
  • Fig. 2 shows the arrangement of the cooling element in a furnace wall.
  • Fig. 3 shows the arrangement in a round furnace vessel
  • Fig. 4 shows the arrangement in a rectangular oven vessel in combination with other systems.
  • FIG. 2 shows that the cooling plate 1 is located directly between the outer casing of a metallurgical vessel 6 and the refractory lining 7 facing the furnace interior. Preferably, it is embedded in a thermally conductive contact mass 8 formed by pounding.
