Definitions

  • the invention relates to a steelworks arrangement according to the preamble of claim 1.
  • drain lines can be straight, curved, closed as circular or oval lines.
  • EP-B 0 061 749 which forms the preamble, discloses a multi-stage steel production process which, in addition to melting the steel, comprises several refining steps, such as analysis adjustment and degassing, and in which certain steel production facilities are arranged in a circular flow line.
  • a pan moves on a floor conveyor along this drain line.
  • the pig iron is produced in a blast furnace outside the discharge line and fed to the discharge line by means of another floor conveyor.
  • this solution does not result in a significant reduction in personnel. Every steel production unit and the crane must be equipped with the appropriate personnel for unit operation and control.
  • the invention has for its object to find a steel mill arrangement, which in addition to an optimal material flow in the Steel production also allows a substantial reduction in personnel, an optimal direct flow of information with clear management structures and a clear process flow.
  • the steelworks arrangement should have practically no emissions and should largely ensure a simplified direct material and media flow.
  • Every drain line is the existence of a center area. It can be selected in an L or U shape with corresponding transitions on the straight legs.
  • a drain line that is arcuate or circular is particularly advantageous.
  • the steel mill arrangement may include facilities that enable continuous steel production. However, it can also include a combination of continuous and sequential manufacturing steps or manufacturing facilities. According to one embodiment, steel production facilities are provided for sequential steel production.
  • Converters or arc furnaces etc. are used for steel production. applicable.
  • An advantageous embodiment is a combination of one or more arc furnaces, preferably direct current arc furnaces, and of devices for metallurgical changes in the molten steel, for example ladle furnaces and / or a steel degassing unit.
  • a continuous caster is advantageously connected directly or via a holding furnace to a continuous forming device, e.g. Rolling mill, connected.
  • the continuous casting installation can have a continuous conveying direction which runs away from the control station in the form of a radiation. If the continuous casting device has an arcuate mold, the operating side for the mold is advantageously arranged on the outside of the casting curve.
  • the transport and lifting devices are also advantageously redesigned.
  • radially arranged cranes cover a circular control surface.
  • the control devices for the cranes are provided in the central control station.
  • the second crane pushes the defective crane in front of it like a carousel, thus covering the entire lifting requirements.
  • An additional increase in performance or an extension of the time available for metallurgical change of the melt can be realized if several stations for treating the steel melt are arranged on their own circular path along the discharge line and a position for transfer or takeover, a preliminary position along the circular path. and post-treatment, a preheating and optionally a parking position are provided.
  • An embodiment that has this objective in mind can provide a roof over the steelworks arrangement that has a gable line that substantially matches the drain line.
  • a collecting pipe for dust and flue gas can be arranged along the gable line with little effort and this can be connected to an exhaust air cleaning system.
  • 3 denotes a device for melting steel, in this example a direct-current arc furnace.
  • This arc furnace 3 can be combined with known scrap preheating and loading devices, not shown.
  • the next steel production device along the discharge line 4 is a device for continuous casting, also called a continuous casting plant 8.
  • the steel produced leaves the discharge line as a billet or bloom block, or as a thin slab or strip.
  • the empty pans of the continuous casting plant 8 are freed of slag along the drain line in subsequent stations 31-33, repaired, if necessary provided with a new outflow control and then prepared for a subsequent tap.
  • the drain line 4 or in a neighboring area can also be provided with brick lining stations with appropriate drying facilities.
  • the circular drain line 4 comprises the drain path of the ladle filled with steel from the arc furnace 3 to the continuous casting installation 8 and then the path of the empty ladle from the continuous casting installation 8 to the arc furnace 3 for a subsequent racking.
  • a control station 11 for the steel production facilities is provided in a tower-shaped building 10. Due to the central position of the control station 11 to the steel manufacturing facilities 5 - 8, it is possible to create fields of view 12, 12 'to the steel manufacturing facilities 3 - 8.
  • One or more arc furnaces 3 in combination with one or more continuous casting plants 8 are ideally suited for sequential steel production.
  • the facilities for metallurgical changes in the molten steel 5, 6 are designed according to the steel program to be cast and the type of steel melting furnace.
  • several stations 15-19 are arranged along the drain line 4 for treating the steel melts on their own circular path 14.
  • positions for transfer or takeover 15, for pretreatment and aftertreatment 16 or 17, for preheating 18 and / or for parking 19 of pans are generally provided.
  • the continuous casting installation 8 is equipped with an arc mold 20.
  • the intermediate vessel 21 and the pouring ladle 23 are arranged in such a way that the operating side 24 for the mold monitoring lies on the outside of the pouring bend 26.
  • the strand conveyor 27 runs from the central control station 11 radiating away.
  • the control devices for the cranes are also provided in the central control station at several points, each with a direct view of the corresponding working area of the crane. Both the control desks for several steelmaking devices and the control devices for the cranes can be designed on a level 29 in the central control station.
  • a roof 40 above the steelworks arrangement has a gable line similar to the drain line 4. In the example chosen, it is circular. Along the gable line there is a collecting pipe 41 for dust and smoke, which is connected to an exhaust air purification system.
  • primary units 40 can be assigned to such units.
  • the primary housings 40 are designed by segmented boundary walls with optionally immovable, movable or hinged, etc. ceilings 41.
