Definitions

  • the invention relates to a method and a system for rolling out hot wide strip from continuously cast thin slabs in successive working steps of a rolling line having a continuous finishing train, casting strands being produced in one or more casting machines or casting lines, and individual thin slabs being separated from them and each being homogenized and in a compensating furnace Brought rolling temperature and transferred from the compensation furnaces into the rolling line.
  • the following system concepts are known for two and three line systems:
  • the thin slabs coming from different continuous casting machines first pass through an equalizing furnace, then undergo pre-deformation and are wound into bundles.
  • CSP Compact Strip Production
  • an interposed rotary hearth furnace is known from DE-OS 38 21 188.2, which can keep the coils warm.
  • the known method or the corresponding system provides that the primary material is brought to the hot rolling temperature after solidification and wound into bundles, temporarily stored in a rotary hearth furnace and, if necessary, called up, unwound and rolled out into finished strip.
  • the intermediate storage is particularly advantageously carried out immediately before entering the finishing train. Reheating can be carried out during the intermediate storage.
  • Another system concept provides that at the end of the equalizing furnaces arranged in parallel, behind each continuous casting machine there are one or two cross-movable furnace ferries that transport the thin slabs into the area of the rolling mill or rolling line.
  • another known system concept provides that two or three continuous casting machines or casting lines are each arranged at an angle to one another.
  • the compensation furnaces are also arranged in an angularly offset arrangement in the course of the casting lines.
  • a rotating roller table is provided, which picks up the thin slabs from the furnaces and swivels them into the rolling line in the manner of a turntable and in this way feeds them to the rolling mill.
  • the well-known system concepts are based on partially matching tasks, which include consist in keeping the temperature losses of the continuously cast primary material on the way to the rolling mill as low as possible and, in addition to suitable heat-insulating measures, keep short transport routes and times. It is also a matter of harmonizing the casting capacities of several casting machines and the rolling capacity of a downstream rolling mill in such a way that a loss-free overall utilization of the system is achieved for cost-effective operation. The space requirements of the systems and thus the investment costs should also be minimized.

  • the center casting strand (B) or its equalizing furnace (20) is assigned to the roller hearth swivel furnace (5), to which the rolling line x-x with the finishing train (16) is connected.
  • two strands always work, ie either A and B, A and C or B and C, while the third strand is prepared for the next sprue and remains in the stand-by position.
  • the strand that remains in the stand-by position can immediately take up the molten steel from the steelworks. This ensures that two strands always produce fully, while the third strand can be prepared for the next sprue.
  • both pivoting furnaces (4a and 5) connect to one another in a straight line connection with their free ends and in the opposite pivoting position in the manner of a switch (8 ) cooperating to form a straight transition (9) from the casting line A to the rolling line xx.
  • the thin slab located in the swivel furnace (4a) and oscillating therein during the swiveling process is transported from the swivel furnace (4a) into the swivel furnace (5).
  • the swivel oven (4a) swivels in the horizontal plane, ie upwards in the figurative representation and the swivel oven (5) downwards into the respective starting position.

As a result, buffer zones between the equalizing furnaces (19 - 21) and the swivel furnaces (4a, 5, 4b) are kept free so that they can be used in the event of a brief malfunction in the rolling mill area or for changing the work rolls can. It is also possible to transport thin slabs from all three strands (A, B, C) producing at the same time.
  • a route / time network plan is shown in FIG.
  • the example shows a thin slab (19c) of the strand or the casting line (C) and a slab (20a) of the strand or the casting line (A). Both slabs are approx. 50 m long.
  • the slab (19c) is transported in the equalization furnace (21) by one slab length and requires about 70 seconds for this on the ordinate time scale. In a further 70 seconds, the slab (19c) is then introduced into the swivel furnace (4b) and initially remains in the waiting position, being oscillated back and forth as indicated by the double arrow (21).
