Definitions

  • the invention relates to a method for producing a metal strip by casting rolls, in which first in a casting machine a slab of nominal slab thickness is poured by discharging metal at a nominal casting speed from a mold, wherein the slab in the region of a strand guide by a number of roles of a Wherein the slab is subsequently tempered in a furnace of defined length, the slab being rolled behind the furnace in a rolling train and, in particular, the slab behind the casting machine and in front of the furnace in a roughing mill reducing thickness to a nominal reshaped slab thickness or thickness Substrate thickness is subjected.
  • the slabs or pre-strips are separated into individual slabs or individual pre-slats so that coils of the desired size are produced after hot-rolling.
  • Thin slab plants mainly work as a slab process.
  • the slab process it is characteristic that the conservation of energy and the required heating of the slab, for example in a roller hearth furnace, which is longer than the maximum slab length. This allows you to separate all slabs so that in a certain period of time, the individual slab is completely in the oven, ie neither in G confusen Siemens is still engaged in the rolling range of the finishing train.
  • Typical thicknesses of the slabs are between 40 mm and 100 mm.
  • the so-called ISP process works with smaller intermediate strip thicknesses, which are typically in the range between 10 and 20 mm.
  • the individual intermediate belts are always engaged either in the casting area or in the rolling area of the finishing train.
  • the intermediate buffering of the pre-bands is carried out by means of two heated coiling ovens, which conserves the temperature of the pre-bands after reheating.
  • the disadvantage is the following: It is difficult to comply with the final rolling temperature, since the rolling speed in the finishing train is directly coupled to the mass flow from the casting machine. This can only be achieved by a consistently high casting performance and by reheating the intermediate belt to very high temperatures after roughing. Furthermore, the required final rolling temperatures can not be achieved for all steel grades, so that certain grades can not be produced in continuous operation. Then it is disadvantageous that in a required roll change, the sequence must be completely stopped. In case of faults, for example, in the casting operation, the endless operation is interrupted, it must then be switched to batch mode. If the ESP process switches to batch mode, then due to the small distances between the caster and the finishing mill only so-called "mini-coils" produced.
  • a method for producing a metal strip by casting rollers in which first a thin slab is cast in a casting machine. This is then rolled in a rolling mill using the primary heat of the casting process.

  • a discontinuous production of the metal strip can take place by decoupling the casting machine from the at least one rolling train (batch operation).

B. due to a roll change, on the other hand to ensure the smallest possible furnace length to work optimally in continuous operation can.
  • a combined continuous / batch process is to be provided which overcomes the above disadvantages of the ESP process with cost effective means.
  • additional storage ovens adjacent to the transport line or oven extensions should be avoided.
  • the slab may be cut (separated) on a pair of shears located in front of the furnace.
  • the inlet velocity of the slab into the furnace is preferably reduced by at least a factor of 2 compared to the nominal value.
  • the thickness reduction of the slab in the area of the strand guide is preferably reduced by up to 40 mm.
  • the temporary reduction, in particular the temporary interruption, the supply of rolling stock in the rolling train can be made while in the rolling mill a roll change is made or there is a different production delay in the rolling mill.
  • the slab After making the temporary reduction in the supply of rolling stock in the rolling mill, the slab can be processed in batch batch operation. This is due to the process for the first slab after a roll interruption.
  • the slab can, as long as a temporary reduction of the supply of rolling stock in the rolling train is not carried out, be processed in the continuous rolling process.
