Definitions

  • the invention relates to a method and a Device for the production of hot rolled Steel strip made of continuously cast material, preferably Thin slabs, with successive ones in a heat Steps of a CSP process, the primary material after solidification in lengths is divided into the desired bundle weight correspond and the thin slabs in one Compensating oven homogenized, then in one Rough rolled mill, in a finishing train finish rolled, cooled in a cooling zone and opened to wind up a reel.
  • the invention is based on the object Method and a corresponding device for the production of hot rolled steel strip to improve that all known Steel grades are rolled with absolute flexibility can.
  • Step 1 can next to the previously possible Steel grades also rolled such steel grades where the first stitch in the pre-deformation framework Requires temperatures above that z. B. by the temperature resistance of the rollers, their bearings and drives determine maximum Temperature of the equalizing furnace.
  • step 2 is an optimal structure possible, so that unconsolidated, relaxed Material for the finishing train is available stands. This is done through a material specific Rolling time in the recrystallization zone reached.
  • Step 3 ensures that the temperature for the first pass in the finishing train after rolling technology Viewpoints, accordingly the necessary temperature profile in the finishing train optimally set for all steel qualities can be.
  • the feature of claim 4 allows one short-term, quick heating of the rolled stock, so that rapid changes between the rolling stock qualities pose no problems.
  • Figure 1 shows a continuous casting machine 1
  • the A pair of scissors 2 is arranged to divide of the continuously cast molding material in thin slabs 3 serves the desired coil weights correspond.
  • the scissors 2 are included Compensating furnace 4 to which another pair of scissors 5 follows.
  • an induction heater 6 provided that if necessary the from the equalization furnace 4 emerging thin slabs 3 Can heat up temperatures above 1150 ° C.
  • the induction heater 6 closes a scale washer 7 and a roughing train, here a pre-forming stand 8 to which the recrystallization zone 9 follows.
  • a winding device 10 and an unwinder 11, e.g. a coil box is provided in the recrystallization zone 9 .
  • the take-up reel 10 and the unwinders 11 is a Holding oven 12 is subordinate, in which if necessary ready-wound coils for interim storage and recrystallization purposes can be.
  • a cooling device 13 is provided, by means of which keeps the rolled strip at optimal temperatures for the subsequent finishing train 14 cooled and if necessary can be descaled.
  • On the finishing train 14 also closes a cooling zone 15 and a take-up reel 16.
  • Figure 3 shows two continuous casting machines arranged in parallel 1, 1 ', two scissors 2, 2' and two Compensating furnaces 4, 4 '.
  • the equalizing furnaces 4, 4 ' is followed by a ferry 17, which is a ferry 18 has.
  • the ferry 18 can the thin slabs 3, 3 'alternately from the Compensating furnaces 4, 4 'transported into the rolling line become.
  • FIG. 4 shows that the continuous casting machine 1 ' the scissors 2 'and the equalization furnace 4' in line are arranged with the rolling mill while the Continuous casting machine 1, the scissors 2 and the equalizing furnace 4 parallel to it outside the rolling line are provided.
  • the ferry 17 also serves here to alternately supply the rolling line with rolling stock. A constant casting and rolling process is to be ensured behind the ferry 17 Memory 19 provided, which is heated or can be unheated and in line with the rolling mill is arranged.
