Definitions

  • the invention relates to a method for manufacturing a refractory monolithic lining from Wall and bottom of a pan for pouring and treating of steel or similar metallurgical vessels and an apparatus for performing the method.
  • the structure is made of refractory Lining of metallurgical vessels from permanent feed and working feed.
  • Usually are used as permanent feed Firebricks or insulating bricks in one or several layers on the steel jacket of the vessel inside applied.
  • the working feed is applied to it, that later in contact with the molten steel stands and due to erosion, especially when moving the metal bath, as well as by chemical attack, in particular by floating on the molten steel Slag is removed.
  • the working lining can be bricked with refractory bricks are introduced or introduced as a refractory mass that solidify into a monolithic layer. Combinations of these two types of delivery are also possible.
  • the working feed is after repeated filling and emptying the pan either at the end of the pan trip completely broken out and renewed or with only partial leading wear in the affected Zones repaired.
  • the floor wears out frequently faster than the wall, especially in the area of the Pouring jet impacts and in the vicinity of sink blocks. Then the soil must be fed during a pan trip be broken out and renewed several times.
  • the object of the present invention is therefore with a monolithically delivered steel casting and treatment ladle to feed the soil so that a breakout of the floor lining between the wall lining without damaging wall areas in economical is made possible in a favorable manner.
  • the task is solved in that at the beginning of pouring the casting compound into the wall area a tubular, attached to the lower part of the template, inflatable sealing body is inflated so that the template is up to the height of the desired one Floor thickness corresponds, seals. Once the setting the casting compound in the lower wall area is sufficient is advanced, the sealing body is relaxed and removed again. Then the refractory Casting compound in the floor area up to the desired height brought in.
  • the sealing body After inflating the sealing body is first poured the wall lining, the sealing body preventing that the mass runs into the ground. If the wall lining is poured to the edge of the pan is, the lower part of the lining begins, which is the sealing body touches, starting from the surface already easy to solidify so that the sealing body relaxes and can be removed. After that, before the Stencil is drawn, the floor up to the predetermined Poured height. The soil lining builds up this way with the wall lining no monolith more, but there is a predetermined breaking edge. Because joint formation is avoided later in use the pan also has no infiltration of molten steel instead of. After the setting time, which is usually up to can be ten hours, the template is made the pan pulled out and the pan food on Operating temperature warmed up.
  • Fig. 1 shows the perspective view of a steel pouring and treatment pan with (from outside to inside) the Steel jacket, the permanent lining provided with stones, the working lining in the wall with mass and the template (4).
  • the pan bottom is not yet delivered with monolithic mass. It is a dishwashing and a tap hole brick recognizable as well as a cast one Prefabricated component made of high-alumina material as a baffle plate on the permanent feed.
  • the stencil stands on fire-proof support bodies (1), which have the same height as the perforated stones.
  • the bottom edge of the template (4) is on the inside Ledge (3) on the tubular, inflatable Sealing body (2) made of flexible material are attached.
  • the Sealing bodies (2) can, for example, be made of reinforced plastic Rubber.
  • Fig. 2 shows the longitudinal section through the pan Area at the bottom of the template (4).
  • Something above the lower edge of the template (4) is a Ring attached, which carries a bar (3) on the inside.
  • the strip (3) is made of a tubular sealing body (2) attached flexible material.
  • To protect against damage is the sealing body (2) on the refractory Material facing side with a protective strip (5) made of tear-resistant, flexible material.
  • Fig. 3 shows a top view of the pan bottom.
  • the refractory support body (1) is shown in the sectional view, which, for example, be frustoconical can, and two sealing bodies (2) cut to size are that they are inflated without further ado Aid is sufficiently close to the support body (1) invest.
