Definitions

  • the present invention relates to a method for continuously casting a metal strand in a continuous casting plant.
  • the invention relates to a method for continuous casting of a metal strand, in particular a steel strand, in a continuous casting, wherein a strand drawn with a trapped by a strand shell, liquid core drawn from a cooled continuous casting mold, in a continuous casting mold downstream strand support, supported, cooled with coolant and optionally metallurgically reduced, wherein thermodynamic state changes of the entire strand in a mathematical simulation model, including a heat conduction equation, are also calculated.
  • rollers in the segment upper frame and in the segment subframe are positionally and / or pressure-controlled by pairs of hydraulic piston-cylinder units on frame traverses, being switched from a position to a pressure-controlled operation for guiding and / or pressing the casting strand when the pressure within the respective pair of piston-cylinder units reaches a predetermined maximum value.
  • a metal strand shrinks during its solidification i. a change of strand dimensions
  • the size of the strand shrinkage occurring depends on the operating parameters of the continuous casting plant, for example on physical parameters of the metal to be cast, the casting temperature, the casting speed, the strand thickness or the strand cooling.
  • the object of the invention is to provide a method of the type mentioned, with which the product quality of a metal strand, for example by reducing the porosity and / or segregations, improved surface quality and / or shape retention, can be further improved.
  • This object is achieved by a method of the type mentioned in the mathematical simulation model, a natural shrinkage of the strand in real time, taking into account the physical parameters of the metal, the temperature of the metal in the casting manifold, the constantly measured pullout speed, the strand cooling and the thickness of the Strand is also calculated and adjusable strand strand guide rollers of the strand support device can be adjusted taking into account the natural shrinkage of the metal strand.
  • the mathematical simulation model When calculating the natural shrinkage of the strand, the mathematical simulation model generates a heat equation in real time, taking into account the physical parameters of the metal, the temperature of the metal Metal in the casting manifold, the constantly measured extraction speed, the strand cooling and the thickness of the strand solved numerically.
  • the strand is discretized, ie, for example, divided into a plurality of volume elements, and the heat equation equation periodically resolved taking into account the initial and boundary conditions by means of a process computer for the plurality of discrete elements, resulting in the time-varying temperature field of the entire strand.
  • Natural shrinkage is the thermal expansion behavior of the strand as a function of temperature changes.
  • the natural shrinkage of each element can be calculated, for example, from the volume expansion or contraction. If the metal strand is not to be further metallurgically reduced, the distances of the strand guide rollers that can be attached to the strand in the strand thickness direction are adjusted such that these distances follow the natural shrinkage of the metal strand in the strand extraction direction.
  • Two further advantageously embodiments of the method according to the invention result when a further metallurgical reduction of the metal strand in the strand support device, for example a liquid core reduction, a soft reduction (in particular a dynamic soft reduction) or a surface treatment, takes into account the natural shrinkage of the metal strand becomes.
  • a further metallurgical reduction of the metal strand in the strand support device for example a liquid core reduction, a soft reduction (in particular a dynamic soft reduction) or a surface treatment, takes into account the natural shrinkage of the metal strand becomes.
  • a metallurgical surface treatment of the metal strand in the strand support device is also known from EP 1289691 B1 known.
  • the method according to the invention is carried out when the thermal equation is solved numerically in the mathematical simulation model taking into account temperature-dependent density changes of the metal strand.
  • the change in density of metal as a function of the temperature can assume significant proportions.
  • the density of steel increases from approx. 7000 kg / m 3 at 1550 ° C (melt temperature in the casting distributor) to approx. 7800 kg / m 3 at 300 ° C (solidified strand).
  • a further advantageous embodiment of the method according to the invention is that in the numerical solution of the heat equation, taking into account temperature-dependent density changes of the metal strand approximated equations are used for the enthalpy, which have the exact mass and the exact enthalpy for the entire strand.
  • the mathematical simulation model includes a computational model describing the formation of a desired microstructure in the metal strand, in a particularly advantageous manner by the application of a continuous Avrami phase conversion model.
  • the strand cooling is adjusted taking into account the calculated thermodynamic state changes.
  • the inventive method can be used without restriction in the casting of metal strands with billet, billet, slab or thin slab cross section of any size in order to improve the quality of the cast metal strands.
  • a further advantageous embodiment of the method according to the invention is to employ the strand guide rollers which can be attached to the strand in such a way that the thickness of the strand corresponds as closely as possible to a desired value.
  • a controller with the aid of a control law and taking into account the setpoint and the natural shrinkage of the strand determines a manipulated variable, which is supplied to at least one engageable strand guide roller, so that the thickness of the strand corresponds to the desired value as possible.
  • the controller assumes either the calculated thickness of the strand or a measured beach thickness. in the In the first case, the calculated thickness is used to determine the manipulated variable, so that the thickness of the strand or a distance between the strand guide rollers need not be detected separately.
  • the thickness of the strand is detected by means of a measuring device and fed to a controller, wherein the manipulated variable is determined taking into account the detected thickness of the strand.
  • the steel strand 1 no further metallurgical reduction, for example, Liquid Core Reduction, soft reduction or surface treatment of the strand are subjected, where the distance of strandable strand strand guide rollers 7 of the segments 13 via one or more hydraulic cylinders 15 to the calculated strand thickness, i. considering the natural shrinkage, adjusted.
  • the thickness changes necessary for the reduction are superimposed on the calculated strand thicknesses, taking into account the natural shrinkage.
  • the method according to the invention is independent of the dimension of the heat equation and can therefore also be used without restriction with equations of other dimensions, e.g. three-dimensional equations, are used.
  • the heat equation becomes Lagrangian coordinates x Lag transformed, ie viewed by a moving along with the strand extraction movement observer.
  • the Lagrangian thermal equation can be solved by standard methods of numerical mathematics, such as the finite volume method.
  • Fig. 2 an adjustable segment 13 of the strand support device is shown in more detail.
  • a parallel (as shown) or conical course of the strand thickness of the steel strand 1 can be set.
  • the thickness of the steel strand 1 can be adjusted via a hydraulic adjustment of the segment 13, wherein in a displacement measuring system of a hydraulic cylinder 15, the actual position and thus the distance between opposite strand guide rollers 7 measured and passed on to the process computer.
  • the process computer 14 calculates the natural strand shrinkage via the solution of the heat conduction equation and takes it into account in further metallurgical reductions, in the specific case of an LCR reduction with a liquid core 8, and thus specifies the target thickness of the steel strand 1.
  • a manipulated variable is determined by means of a nominal-actual comparison of the strand thickness and output to an electro-hydraulic valve which is assigned to the hydraulic cylinder 15.
  • the segments 13 can be used on the one hand for the adjustment of the strand guide rollers 7 to the natural strand shrinkage, on the other hand can be realized on appropriate positions of the rollers 7, of course, all metallurgical reductions in the strand support device.
