Definitions

  • the invention relates to a steelworks arrangement according to the preamble of claim 1.
  • EP-B 0 061 749 which forms the preamble, is a multi-stage Steel manufacturing process known in addition to Steel melting several refinement steps, such as analysis adjustment and degassing, and in which certain steelmaking facilities in a circular drain line are arranged.
  • a pan moves on an industrial conveyor along this drain line.
  • the pig iron is in one Blast furnace generated outside the drain line and by means of a further conveyors to the discharge line.
  • this solution does not result in a significant reduction in personnel. Every steel manufacturing unit and also the crane must be operated with the appropriate personnel for unit operation and be equipped for the control.
  • EP-A-219 891 discloses a steel mill arrangement consisting of Steel making equipment such as electric arc furnace, ladle and ladle furnace and plant for continuous casting, which along a self-contained circular drain line, are set up, in the center of the Drain line a turret is provided.
  • the invention has for its object a steelworks arrangement to find, which besides an optimal material flow at the Steel making also a substantial reduction in personnel, one optimal direct flow of information with clear management structures and allows a clear process flow.
  • the steelworks arrangement is next to an inexpensive construction have practically no emissions and largely one Ensure simplified direct material and media flow.
  • drain line There are many in the choice of the geometric shape of the drain line Variants possible.
  • An essential criterion for every drain line is the presence of a center area. It can be L- or U-shaped with corresponding transitions on the straight legs to get voted.
  • a drain line is particularly advantageous, which is arcuate or circular.
  • the steel mill assembly may include facilities that include a enable continuous steel production. But it can also a combination of continuous and sequential Manufacturing steps or manufacturing facilities include. According to one embodiment, steel manufacturing facilities are intended for sequential steelmaking.
  • Converters or arc furnaces etc. are used for steel production. applicable.
  • An advantageous embodiment represents a Combination of one or more arc furnaces, preferably DC arc furnaces, and of facilities for metallurgical Changes in the molten steel, for example ladle furnaces and / or a steel degassing unit.
  • a continuous caster is advantageous either directly or via a Holding furnace to a strand forming device, e.g. Rolling mill, connected.
  • a continuous conveying direction that runs away radially from the control station. Instructs the continuous Pouring device on an arcuate mold, so the operating side for the mold on the Arranged outside of the casting curve.
  • the transport and hoists are also an advantage of the discharge line newly designed.
  • the control devices are intended for the cranes in the central control station.
  • An additional increase in performance or an extension of time available for metallurgical change of the melt can be realized if there are several stations along the drain line for treating the molten steel on its own circular path are arranged and a position along the circular path for handover or takeover, pre- and post-treatment, a preheating and optionally a parking position is provided are.
  • An embodiment that has this objective in mind can provide a roof over the steelworks arrangement that has a gable line that is substantially aligned with the drain line matches. Along the gable line can with little Effort arranged a collecting pipe for dust and flue gas and this can be connected to an exhaust air purification system.
  • a device for melting steel in this example a DC arc furnace.
  • This arc furnace 3 can be known, not shown Combined scrap preheating and loading devices be.
  • a drain line 4 follow devices for metallurgical Changing the molten steel, such as ladle furnaces 5 and steel degassing units 6.
  • ladle furnaces 5 and steel degassing units 6 As the next steel production facility A facility follows along the drain line 4 for continuous casting, also called continuous casting plant 8. In the continuous casting plant 8, the steel produced leaves as a billet or bloom block or as a thin slab or tape the drain line.
  • the empty pans of the continuous caster 8 are following along the drain line Stations 31 - 33 freed of slag, repaired, if necessary with a new discharge control and then prepared for a subsequent racking.
  • the drain line 4 or in a neighboring area can also Pan lining stations with appropriate drying facilities be provided.
  • the circular drain line 4 in this example includes the Drain path of the pan filled with steel from the arc furnace 3 to the continuous caster 8 and then the path of the emptied Pan from the continuous casting plant 8 to the arc furnace 3 for a subsequent racking.
  • a control station 11 for the Steel manufacturing facilities provided in the center area of the circular drain line 4 in one tower-shaped building 10 .
  • the central Location of the control station 11 to the steel manufacturing facilities 5-8 it is possible to view fields 12, 12 'to the steelmaking equipment To create 3 - 8.
  • One or more arc furnaces 3 in combination with one or Several continuous casting plants 8 are ideal for one sequential steelmaking.
  • the facilities for metallurgical changes in the molten steel 5, 6 are according to the steel program to be cast and the type of steel melting furnace.
  • To big ones To achieve casting performance are along the drain line 4 melt several stations 15 - 19 to treat the steel arranged on its own circular path 14.
  • Along this Circular path 14 are usually positions for a transfer or takeover 15, for pretreatment and aftertreatment 16 or 17, for preheating 18 and / or for parking 19 of pans.
  • the continuous casting plant 8 is in this example with an arc mold 20 equipped.
  • the intermediate vessel 21 and the ladle 23 are arranged so that the operating side 24 for the Mold monitoring on the outside of the casting curve 26 lies.
  • the strand conveyor 27 runs from the central control station 11 radiating away.
  • the control devices for the cranes are also in the central control station on several Place with a direct field of view on the corresponding one Work area of the crane provided. Both the control desks for multiple steelmaking facilities as well Control devices for the cranes can be found in the central control station be designed on a level 29.
  • a roof 40 over the steel mill arrangement has one of the drain line 4 similar gable line. In the example chosen it is circular.
  • a collecting pipe 41 for Dust and smoke attached with an exhaust air purification system communicates.
