Definitions

  • the invention relates to a system with a fireproof-lined metallurgical vessel, in particular a steelwork converter, which is provided at its upper end with an opening which can be connected to a chimney arranged at a distance above the opening by means of a hood which can be inserted between the opening and the chimney Removal of the hood into the space located between the mouth and the chimney, a closure device to be covered downward from the chimney can be introduced by means of a carrying device equipped with at least one lifting device.
  • a fireproof-lined metallurgical vessel in particular a steelwork converter
  • the entire lining material In order to be able to brick out the metallurgical vessel, the entire lining material must be introduced into the vessel from above with vessels with a solid bottom. In the case of a vessel with a removable bottom, only the material for bricking up or pouring the floor joint needs to be introduced into the vessel from above.
  • a system of the type described above is known from DE-U-1972034.
  • the closing device covering the chimney opening is designed as a shield, upon removal of which the slag that has fallen onto the shield is stripped off, so that the slag also falls into the freshly bricked converter in this system.
  • the lifting device provided in the known system can only be moved above the mouth of the converter, so that in order to introduce lining material into the metallurgical vessel, either the bottom of the latter has to be removed or the entire system has to be moved to the side.
  • the invention aims at avoiding these disadvantages and difficulties and has as its object to create a system of the type described at the outset, with which the masonry team cannot be endangered and with which it is possible to introduce the masonry material into the metallurgic vessel in a simple, time-saving manner .
  • closure device is designed as a container with at least one closable bottom opening and the lifting device is arranged to be movable on the carrying device from the side next to the mouth of the vessel to above the mouth of the vessel.
  • the container covering the chimney ensures that parts falling down from the chimney, such as slag deposits, are collected and can no longer fall into the metallurgical vessel when the container is removed.
  • the lifting device which is arranged to be movable on the carrying device, automatically comes into the working position, in which lining materials which are set down to the side of the vessel can be introduced into the vessel.
  • the support device is designed as a frame which can be moved along rails and on which at least one travel rail projecting up to the side next to the mouth of the vessel is provided for the hoist.
  • the travel rail is expediently extended on both sides of the vessel to the side of its mouth and equipped with two hoists.
  • Two mutually parallel rails are advantageously provided for receiving at least one hoist.
  • a preferred embodiment is characterized in that the container is formed by a funnel and has a funnel opening which is located centrally above the mouth and can be closed by means of a slide, the travel rail being arranged just to the side of the funnel opening.
  • the funnel-shaped design of the container enables it to be easily emptied by opening the funnel opening. In the case of a metallurgical vessel with a removable bottom, this can take place before the bottom is put through the vessel into the Schlakkenkeller or, in the case of a vessel with a solid bottom, by lateral movement of the carrying device, the accumulated slag falling into a transportable chute.
  • An embodiment in which the lining material can be brought into the center of the metallurgical vessel is characterized in that the container is formed by two funnels lying next to one another, the travel rail being arranged between the funnels in a plane lying through the vertical axis of the mouth.
  • the carrying device is advantageously provided with a working platform that can be inserted through the mouth into the vessel, which opens up the possibility for metallurgical vessels with a solid floor to brick the vessel from above without having to provide its own scaffolding.
  • the carrying device is advantageously provided with a walk-on web, whereby observation of the interior of the vessel from the mouth of the vessel is possible.
  • the support device can advantageously be moved along the rails that guide the hood and can be coupled to the hood or to a chassis that supports the hood.
  • FIG. 1 showing a partially sectioned side view of a converter system in a schematic illustration according to a first embodiment.
  • 2 shows a likewise partially sectioned side view in the direction of arrow II of FIG. 1.
  • FIGS. 3 and 4 or 5 and 6 show two further advantageous embodiments in representations analogous to FIGS. 1 and 2.
  • the converter 1 designates a steel mill converter which can be tilted about a horizontal axis 2, the mouth 3 of which is located below a stationary chimney 4 when the converter 1 is upright.
  • the converter 1 has a steel jacket 5 and a refractory lining 6 on the inside.
  • the chimney 4 ends at a vertical distance 7 above the mouth 3 of the converter 1.
  • a hood 9 can be inserted by means of a trolley 10, the trolley 10 along both sides of the lower one End 8 of the fireplace 4 arranged rails 11 is movable.
  • the hood 9 has such a dimension that it connects on the one hand to the mouth 3 of the converter 1 and on the other hand to the lower end 8 of the chimney 4, so that exhaust gases emerging from the converter 1 get directly into the chimney 4 without disturbing the environment.
  • a support device 12 can be moved along the rails 11 supporting the hood 9 or its undercarriage 10 by means of wheels 13, which support device 12 is formed by a frame 14 which can be positioned just below the lower end 8 of the chimney 4 and surrounds the chimney peripherally. On this frame 15 vertical struts 16 are provided at the corner points, on which the wheels 13 are mounted.
  • a container 17, which is designed as a funnel, is fastened within the frame 14, the lower funnel opening 18 of which is central, i.e. lies in the vertical axis 19 through the mouth 3.
  • the funnel opening 18 can be closed by means of a slide 20, for the actuation of which a handwheel 21 is provided.
  • the upper funnel opening 22 corresponds in shape and size to the lower end 8 of the chimney 4.
  • a frame 23 is mounted on the side of the lower funnel opening 18 and just adjacent to it, which, as can be seen from FIG. 11, extends from above the mouth 3 to the side next to the converter 1.
  • a lifting device 24 for transporting lining material 25 for the converter 1 can be moved along this travel rail.
  • a walkable web 26 is also attached to the carrying device 12, from which the interior 27 of the converter 1 can be observed when the carrying device 12 is positioned over the mouth 3.
  • the carrying device can be coupled to the movable hood 9 by means of a schematically illustrated coupling 28.
  • a drive not shown
  • the carrying device 12 with the funnel 17 and the lifting device 24 automatically reaches the working position shown in FIGS.
  • an extension 29 of the travel rail 23 is drawn in with dashed lines, which makes it possible to move two lifting devices 24, 24 ′ along the same travel rail 23 from the side next to the converter 1 to above the mouth 3 of the converter.
  • This embodiment is particularly advantageous for a converter 1 with a solid floor that can only be bricked up from above.
  • a single lifting device 24 is sufficient, which only has to bring the material for bricking and pouring the joint between the floor and the converter jacket into the interior 27 of the converter.
  • the container is formed by two adjacent funnels 17, 17 ', the upper openings 22, 22' of the funnels complementing one another in terms of area corresponding to the lower end 8 of the chimney 4.
  • the funnels 17, 17 ' are formed symmetrically to a plane 30 placed through the vertical axis 19 of the chimney 4 or the mouth 3 and parallel to the rails 11. Between the funnels 17, 17 ', the travel rail 23 for the hoist 24 is provided as far as possible from the mouth 3, ie just below the lower end 8 of the chimney 4.
  • the travel rail 23 thus lies in the vertical plane 30 through the vertical axis 19 of the mouth 3, as a result of which the lifting device 24 can be brought into position exactly above the mouth 3 of the converter 1, so that even larger pallets can easily enter the interior 27 of the converter 1 can be lowered.
  • a travel rail 23, 23 ' is provided on each side of the centrically arranged hopper 17 for a hoist 24, 24'.
  • the carrying device 12 additionally carries a work platform 32 which can be raised and lowered by means of cable pulls 31 and which can be adapted to the shape of the interior 27 of the converter 1 by means of lateral arms 33.
  • a drive motor 34 is used to raise and lower the work platform 32, which is coupled via articulated shafts 35 to the drums 36 that wind the cables of the cables 31.
