Definitions

  • the invention relates to a vessel for a melting furnace, in particular an electric furnace, consisting of a heat-resistant vessel wall, which above the melt level is composed of a plurality of expandable cooling units provided with water or evaporative cooling, and distributed on the periphery of the vessel and arranged on the outside of the vessel wall the support structure of the lower vessel connected vessel supports and an upper edge supporting the vessel lid.
  • the upper edge projecting over the cross section of the vessel is supported on supports distributed around the circumference of the vessel.
  • four fixed supports are provided, while part of the supports can be removed laterally from the area of the vessel wall (DE-OS 30 24 549).
  • the invention is therefore based on the object of improving the known vessel in such a way that the replacement of the cooling units is made considerably easier.
  • the solution to the problem is that the upper edge consists of individual edge sections combined with the cooling units. It is useful that each edge section is composed of several different profiles firmly connected to each other.
  • each edge section has a T-profile, a thick-walled tube for the upper coolant guide and two flat profiles resting on the stents.
  • each edge section is connected to the stents by means of releasable connecting elements.
  • the partial section of an oven vessel shown in FIG. 1 contains a lower vessel 1 lined with refractory bricks, which rests in a supporting structure and is surrounded by a vessel jacket sheet 2.
  • a plurality of vessel supports 3 are arranged on the circumference of the vessel and are connected to the supporting structure of the lower vessel 1.
  • the vascular supports 3 can be designed as box girders 3/1, 3/2 ... 3 / n, the upper end of which protrudes laterally Form support plates 4.
  • the vessel wall 5 consists of a multiplicity of interchangeable cooling units 5/1, 5/2... 5 / n arranged on the side of the vessel supports 3 facing the furnace interior, which cooling units can be designed as tube bundles or individual cooling boxes with flow forced by baffles.
  • the edge 6 is divided into individual edge sections 6/1, 6/2 ... 6 / n corresponding to the number of cooling units 5/1, 5/2 ... 5 / n and combined with the cooling units to form a structural unit.
  • the edge sections 6/1, 6/2 ... 6 / n lie on the support plates 4 on the vessel supports 3 and are connected to them by means of screws 8. This ensures the rigidity of the vessel.
  • Each edge section is composed of a T-profile 9, a thick-walled tube 10 for the upper coolant guide and two flat profiles 11 resting on the support plates 4 of the vessel supports 3.
  • the cooling units 5/1, 5/2 ... 5 / n extend from the upper edge of the vessel 6 to the area of the refractory lining of the lower vessel 1.
  • the joints between the individual cooling units and the fireproof masonry are filled with ramming or spraying compound.
  • a cooling unit 5/1, 5/2 ... 5 / n is arranged between two box supports 3/1 and 3/2 to 3 / n.
  • the cooling units are correspondingly shorter.
  • FIG. 3 shows the coolant supply to the furnace.
  • Evaporative cooling is preferably used, which is designed such that there is little or no condensation of the steam in the individual cooling units.
  • two manifolds 14 and 15 are routed around the furnace, to which the cooling units 5/1, 5/2 ... 5 / n between the box carriers 3/1, 3/2 ... 3 / n are independently connected
  • Supply lines 16 and discharge lines 17 are connected via shut-off devices 18.
  • the lines 17 are connected to the thick-walled tubes 10 of the edge sections 6/1, 6/2 ... 6 / n.
  • the area of the container wall 5 directly adjacent to the furnace cover 7 is thus sufficiently cooled.
  • the lines 16 and 17 are separated from the cooling unit and the screw connections 8 between the edge section 6/1 and the box girders 3/1 and 3 / n are loosened.
  • the brittle layer of slag and the spray compound burst off in the area of the joints as a result of a quick, jerky pull-up using a crane and lifting tongs, and the cooling unit can be lifted upwards.
