Definitions

  • the invention relates to a lining device for metallurgical vessels, in particular for steelwork converters, with a work platform that can be raised and lowered and a stone transport wagon that can be moved on it.
  • Such devices are used to break out and reposition metallurgical vessels whose refractory lining is worn out after a certain number of batches.
  • the refractory bricks are transported either from below or from above into the metallurgical vessel to be newly set up, temporarily stored on the work platform and transported from there to their predetermined position.
  • the work platform is therefore always assigned a stone transport device which consists of a stone elevator if the stones, whose weight is between 36 and 75 kg, are transported from the hall of the iron and steel works to the work platform. Similar stone transport devices are used to feed the stones from above. Because of the dead times to be avoided in the metallurgical operation, the transport of the stones is of considerable importance in order to return the metallurgical vessel to its use as quickly as possible.
  • Such devices are therefore required to facilitate the delivery work in metallurgical vessels, to reduce the delivery times and to increase the lining performance. These conditions can be met by a continuous transport flow of the stones on horizontal and vertical stone conveyor routes. Automation of the stone transport should also save workers or free them up for work on the work platform. The work on the work platform is therefore significantly influenced by the design, structure and mode of operation of the device used.
  • the rotatable platform requires a rotary drive.
  • the size of the mobile stone setting device with the lifting device only one such vehicle can be used at a given time. This creates the difficulty that it is only possible to work at one point on the vessel to be bricked up. This way of working does not meet the requirement mentioned at the beginning of reducing delivery times and increasing the brickwork performance.
  • the invention has for its object to achieve a higher specific masonry performance without a greater effort on driven units, d. H. improve the delivery work in metallurgical vessels, reduce the delivery times and, despite the simpler device, make work easier for the personnel.
  • the stated object is achieved in the bricking device described in the introduction in that tracks run on the work platform to several circumferential locations of the lining, on each of which a stone transport carriage can be moved, that each stone transport carriage has a lifting table and that the lifting table has a substantially in the respective direction of the Track-laying, adjustable stone bridge facing the brickwork is assigned.
  • This device makes it possible to work simultaneously in several places of the delivery to be bricked up. This increases the specific brickwork performance. The delivery time is reduced with higher brickwork performance.
  • the device provided for this purpose is also simple, does not require any particularly long assembly or disassembly times and is accordingly easy to use.
  • the physical strain on the staff is also limited because the stones can be pushed into their operating position without great effort due to the stone bridge.
  • a solution of the proposal according to the invention which can also be used in smaller metallurgical vessels consists in that at least two stone transport wagons are provided on the work platform on tracks running perpendicular to one another.
  • the central areas located between the two circumferential locations of the lining are covered by a corresponding design of the stone bridge.
  • Another design of the bricking device corresponding to the practical conditions provides that the tracks for the stone transport wagons are guided radially outwards from the edge of a stone transport shaft opening into the working platform.
  • the stone packages can therefore also be placed on the stone transport wagon without difficulty, without the individual stone transport wagons interfering with one another.
  • the proposal according to the invention therefore also takes into account a situation which occurs accidentally, in which stone packages have to be supplied to a plurality of stone transport wagons simultaneously by the stone transport device.
  • the stone transport from the hut hallway can also be facilitated by at least one stone transport carriage being liftable to the level of the tracks by means of the stone elevator.
  • the lifting table is rotatably mounted on the stone transport carriage together with the stone bridge.
  • the rotatability of the lifting table considerably increases the range of action of the stone transport wagon with regard to the lining to be delivered.
  • the lifting table is arranged on a turntable of the stone transport carriage by means of scissor links and a piston-cylinder drive located between them.
  • This drive arrangement allows whole stone packages to be loaded in the retracted position of the lifting table and the respective row of stones to be raised to the height of the stone bridge. As a result, no lifting work is to be performed by the operating personnel of the device.
  • a further prerequisite for the targeted increased brick lining performance is created by the loading area of the lifting table being designed in the size of a so-called Euro pallet (800 x 1200 mm).
  • the stone packages transported on pallets can therefore be transferred directly from the stone transport device to the stone transport carriage by means of a crane device.
  • an improvement of the invention is that the adjustable stone bridge is adjustable in its inclination with respect to the respective brick face. With this adjustable incline, the height difference between the increasing brick height and the set height of the work platform is compensated.
  • the length of the stone bridge can be changed by means of one or more attachable and detachable bridge parts.
  • this measure contributes to reaching areas of the lining between two stone transport wagons and, on the other hand, to take into account a radial enlargement or shortening of the distance between the work platform and the lining in the case of curved linings.
  • the lining device according to the invention can be used in a steelwork converter with a cylindrical or pear-shaped lining profile, in blast furnaces, pig iron mixers, ladles and vacuum vessels provided with a lining as well as in special vessels.
  • the lining device has the work platform 1 with a circular work surface 1 a, which is fastened to lifting devices (not shown), the lifting devices holding the work platform 1 in a suspended construction from above or supporting standing from below.
  • the stone elevator 2 which is only indicated by dash-dotted lines, adjoins the stone transport opening 1b in the work platform 1.
  • tracks 3 and 4 run on the working surface 1 a of the working platform 1 and are oriented toward the peripheral points 5, 6, 7 and 8 (FIG. 3) of the lining 9. Stone transport carriages 10, 11 (FIG. 2) or 12 and 13 (FIG. 3) can be moved on the tracks.
  • the stone transport wagons 10 to 13 each have a lifting table 14.
  • the stone bridge 15 is provided on each stone transport carriage 10 to 13 in the directions 3a and 4a (or in the opposite directions).
  • the desired increase in performance in the production of the lining 9, which is to be built up behind the permanent lining 9a and the sheet metal jacket 9b, is in principle achieved by two stone transport wagons 10 and 11 (FIG. 2), the tracks 3 and 4 of which are in mutually perpendicular directions 3a, 4a run.
  • the stone bridges 15 are to be fastened on the rear side of the stone transport wagons 10 and 11, so that the stone transport wagons 10 and 11 (continuous tracks 3 and 4 may be required) at the circumferential points 7 and 8 can be used. Further possible solutions are described.
  • each stone transport carriage 10 to 13 has a turntable 16.
  • the lifting table 14 is mounted on the turntable 16 by means of scissor links 17a, 17b and is raised or lowered by means of an obliquely installed piston-cylinder drive 18.
  • the loading area 19 of the lifting table 14 has the size of a so-called euro pallet, i. H. a loading area of 800 x 1200 mm, so that unassembled Euro pallets 20 can be processed with compact stone packages 21.
  • the stone bridge 15 is fastened to the frame part 22 via the swivel joint 23 and the inclination can be adjusted and ascertained by means of the toggle levers 24a, 24b.
  • the stone bridge 15 is also advantageously designed in the form of a tongue, which makes it easier to place the heavy stones 9d on the brick face 9c.
  • the frame part 22 can also be provided such that it can be removed and reattached to the rear side (not shown).
  • the stone transport carriages 10 to 13 can be raised or lowered through the stone transport opening 1b by means of the stone elevator 2 when the stone bridge 15 is folded down (shown in broken lines).
  • the loading of the stone transport wagons 10 to 13 can therefore advantageously already take place in the hut hallway, so that the stone transport wagons are moved into the stone elevator 2 in the hut hallway, then lifted and brought to the peripheral points 5 to 8 on the working surface la. At this altitude, the stone bridge 15 is folded back into its working position.
