Definitions

  • the invention relates to a method and a device for Production of steel strands in slab format.
  • formed from individual plates Chill molds for producing strands in slab format are placed in the mold due to the low thermal conductivity of the steel, initially only one thin strand shell formed from solidified melt. It is known and is aimed by the continuous caster that the continuous shell in the mold is made with a thickness that is uniform over the circumference, because this thin strand shell outside the mold is the ferrostatic Pressure of the melt located inside must withstand.
  • the expert also knows that the thickness and uniformity of the solidified strand shell at the exit of the mold from a series of Factors, such as casting speed, Steel temperature, geometry, material and conicity of the mold and not least of the type and composition of the lubricant that is applied to the mold level and the friction between Strand shell and mold should reduce.
  • Factors such as casting speed, Steel temperature, geometry, material and conicity of the mold and not least of the type and composition of the lubricant that is applied to the mold level and the friction between Strand shell and mold should reduce.
  • the invention solves the existing problems in a liquid-cooled plate mold for the production of strands Steel in slab format with adjustable between broad side plates Narrow side panels with the Features of claim 1.
  • Advantageous Embodiments of the invention are specified in the subclaims.
  • Fig. 1 shows in principle a mold for the production of strands in slab format.
  • the mold is formed by the Broad side plates 3, 4 and arranged adjustably between them Narrow side plates 1, 2. All four sides are known per se Wise water-cooled, i.e. with one water inlet and one water outlet each provided, the narrow sides with known means for adjustment different strand widths as well as the taper. Because this is facts known to the person skilled in the art, they are in the drawing not shown.
  • the water inlet temperature is 5 recorded, as a rule this will be the same for all four plates, so that one measurement is sufficient.
  • the water has passed through the mold is for each of the narrow and broad side plates 1, 2, 3, 4 Temperature of the water as close as possible to the junction of the Water drainage detected on the mold plate, as well as that on each side of the Quantity of water supplied to plate (reference numbers 6 to 13).
  • the specific heat load (more specific Temperature value) can be determined.
  • the values K1 to K6 are evaluated at intervals or also continuously recorded, the result for an ideal state is: always defines an equal shell thickness of the strand in the mold a certain ratio of the K values to each other or a certain one Curve. Deviates one or more values by a certain amount the other simultaneous values, this is an indication of one Disruption of the heat transfer and thus for a change in Strand shell formation in a locatable area of the mold, the at the same time, a warning for a strand break to be expected indicates. This risk can be avoided early by correcting the taper the mold, changing the casting speed, the oscillation parameters or the mold powder composition can be met.
