Definitions

  • the invention relates to a method for producing a fireproof monolithic lining of walls and floors a pan for casting and treating steel or similar metallurgical vessels and a device for Execution of the procedure.
  • the refractory lining is usually constructed of metallurgical vessels from permanent feed and Working feed. Usually are used as permanent feed Firebricks or insulating bricks in one or more Layers applied to the inside of the steel jacket of the vessel. The working fodder is applied to it, which later with the Molten steel is in contact and due to erosion, especially when moving the metal bath, as well as by chemical attack, particularly by the on the Melting steel floating slag is removed.
  • the working lining can be bricked with refractory bricks are or are introduced as a refractory mass, which too solidified in a monolithic layer. Combinations of these both types of delivery are also possible.
  • the working feed is after repeated filling and Empty the pan either at the end of the pan trip completely broken out and renewed or only partially leading wear repaired in the affected zones.
  • the floor often wears out faster than the wall, especially in the area of pouring jet impact and in the Surroundings of sink blocks. Then the floor fodder has to broken out and renewed several times on a pan trip.
  • Mixers, pumps and internal vibrators are used.
  • the shedding over a period of three hours for example be carried out continuously to check for possible curing to avoid in the surface area. Due to the vibrators the formation of voids and cavities can be prevented in order to achieve good compaction. If the crowd has set after 24 hours, for example Template be pulled out again.
  • the object of the present invention is therefore in a monolithic steel casting and treatment ladle to feed the soil in such a way that the Floor lining between the wall lining without damaging Wall areas in an economically advantageous manner becomes.
  • the task is solved in that at the beginning of the Pour the casting compound into the wall area at the bottom Part of the template attached tubular inflatable Sealing body is inflated so that the template up to Height, which corresponds to the desired floor thickness, seals. As soon as the casting compound sets in the lower wall area the sealing body is relaxed and removed again. Then the refractory Casting compound in the floor area up to the desired height brought in.
  • An advantageous embodiment of one for performing the Method suitable device is that the Template on three fireproof spread over the circumference Bodies (1) that have the same height as that desired thickness for the floor lining.
  • Sealing body (2) attached to the lower edge of the template can be inflated and removed.
  • the wall lining is first poured, the sealing body prevent the mass in runs into the floor. If the wall lining by The bottom of the pan begins to pour Lining that touches the sealing body comes off the surface starting to solidify easily, so that the Sealing body can be relaxed and removed. After that Before the template is drawn, the floor is up to cast predetermined height. The bottom lining forms on this Don't use monoliths with the wall lining, but instead creates a predetermined breaking edge. Since joint formation is avoided, no infiltration occurs later when the pan is used of molten steel instead. After the setting time, the can usually be up to ten hours Pull the template out of the pan and the pan lining heated to operating temperature.
  • FIG. 1 shows the perspective Representation of a steel pouring and treatment pan with (from outside inside) the steel jacket, the one with stones permanent feed, the mass delivered Working lining in the wall and the template (4).
  • Pan bottom is not yet of monolithic mass delivered. They are a rinsing stone and a tap hole recognizable as well as a cast prefabricated component high-alumina material as a baffle plate on the permanent lining.
  • the template stands on refractory support bodies (1) that the have the same height as the perforated stones. At the bottom of the There is a bar (3) on the inside of the template (4) tubular, inflatable sealing body (2) made of flexible Material are attached.
  • the sealing body (2) can for example made of plastic-reinforced rubber.
  • Fig. 2 shows a longitudinal section through the pan on the area lower end of the template (4). Slightly above the lower one A ring is attached to the edge of the template (4) carries a bar (3). There is a on the bar (3) tubular sealing body (2) made of flexible material attached. The sealing body is used to protect against damage (2) on the side facing the refractory material a protective strip (5) made of tear-resistant, flexible material Mistake.
  • Fig. 3 shows a top view of the pan bottom. Is shown in the sectional view of the refractory support body (1) for Example can be frustoconical, and two Sealing body (2) which are cut so that they in inflated condition without any additional aids place close to the support body (1).
