Definitions

  • the invention relates to a method for casting a cast strand in a continuous casting machine equipped with a process computer having at least one casting machine, wherein the process computer comprises a first software which calculates in real time and regulates the casting process.
  • WO 2000 05014 A1 From the WO 2000 05014 A1 is a casting mill with a computing device known to be handled with the various production orders.
  • the sequence of slabs belonging to the production orders is determined within the sequences with the computing device by a "genetic" algorithm, and the cast roll plant is controlled by the computing device according to the determined sequence.
  • the "genetic" algorithm should be able to "take into account the technical and order constraints in an optimized way to allow optimized operation of the casting mill.
  • the WO 2004 048016 A2 discloses a method and apparatus for continuously casting slab, thin slab, billet, pre-profile, billet strands and the like of liquid metal, particularly steel material.
  • There is a system control with a computer to which the respective local measured values of the cooling medium, the cooling medium quantity, the cooling medium pressure of the secondary cooling zone and the measured values of the setting forces of the support roll stand and the surface temperature at the bottom end of the metallurgical strand length are fed online on the input side.
  • the WO 1996 28772 A1 relates to a control system for a plant of the raw materials or the processing industry, in particular for a metallurgical plant.
  • a control system is used, which is based on entered input prior knowledge, automatically provide situation-specific instructions for safe and optimal (optimal) process control.
  • control system has a basic functional system for the system components, which the instructions from the computational, z. B. from a process model, preferably a process overall model, knowledge gained, safely implemented in the plant management.
  • WO 2005 120747 A1 discloses a method for continuously casting a metal strand with a continuous casting mold and a downstream strand support device.
  • continuous casting is carried out on the basis of a thermomechanical calculation model describing the stress on the metal during casting and during the solidification process taking place, with which the stress state of the strand is calculated online.
  • the variable influencing the material load such as the specific cooling amount provided for cooling the strand, is set during the ongoing casting process.
  • a calculation model describing the crack-sensitivity of the microstructure and the crack-formation energy stored in the structure of the microstructure is used to form the desired crack-free microstructure.
  • WO 2004 080628 A1 describes a cast rolling mill for producing a steel strip in which all components of the plant are guided by technological control loops.
  • the system comprises control circuits based on mathematical models, which interconnect the liquid steel device, the liquid steel adding device, the casting device, the reduction device, the deflection device, the rolling mill and the coiler of the casting rolling mill.
  • the individual parts of the system are coordinated with each other in terms of their interaction in coordination such that take into account the effects of the control steps of a part of the plant on following in mass flow direction plant parts.
  • the solidification is achieved by the primary cooling of the steel in the mold and the secondary cooling in the region of the strand guide.
  • water or a water-air mixture is injected under pressure in the remaining between the strand guide rollers areas directly on the strand shell; As a result, heat is removed from the strand.
  • the course of the solidification can be divided into different phases.
  • a thin strand shell solidifies with a thickness of a few millimeters, which is characterized by a fine-grained structure. Due to the high solidification rate, differences in the chemical composition due to diffusion can not be compensated practically. Therefore, the composition of the alloying elements in the strand shell deviates from the proportions of the respective elements in the melt. For example, some elements accumulate in the melt.
  • a phase of directional dendritic solidification begins with the major axes of the dendrites aligned along the heat flow direction. Again, the solidification rate is still so high that some alloying elements continue to accumulate in the residual melt. Part of the enriched melt remains between the dendrite arms, so that the chemical composition of the solidified strand shell can change within short distances.
  • the fluidity of the solidifying residual melt prevent the geometric relationships between the growing strand shells from a certain time, ie when reaching the so-called critical sump diameter, the further exchange of the melt.
  • the so-called "soft reduction” as for example, already from the EP 0 450 391 B1
  • a method for reducing unwanted segregation effects is available.
  • the strand thickness is reduced in the field of Enderstarrung by external forces in addition to the thermal shrinkage, so as to compensate for the increased volume reduction of the liquid strand core and to prevent the suction of enriched residual melt.
  • this object is achieved in a method of the aforementioned Art solved by the fact that a second additional, fast computing software in the process computer, the casting process during the initial phase of a new incipient casting process or a parameter change of the casting strand to be cast during the current process influenced by the second software currently obtained data from the current casting process and / or processes stored data from a database and generates correction factors with which the second software generates corrected target data for the casting process, up to the time when the casting process with the data calculated in real time is completely displayed and the first software exclusively with these Data governs the casting process.
  • the productivity is increased by already in the first cast meters can be given the values or ranges of values of the cast strand specified for the current operation. This is achieved by installing additional software parallel to the real-time compute first software, the second high-speed software to generate the setpoint data at the start of the process or when changing process parameters such as the thickness and width of the casting strand.
  • the task of the second software is to use the process parameters and the nominal values (target temperature, nominal position of the critical sump diameter or the target sump tip) to determine the necessary quantities of coolant (quantities of water) at the start of casting or when switching on the control. This is particularly important because the setpoints are strongly influenced by the current process parameters such as the actual analysis, the superheat of the melt, the current coolant temperature of the coolant (water) of the secondary cooling and the heat dissipation in the mold.
  • the second software uses both process parameters and nominal sizes of the casting process.
  • CMD critical sump diameter
  • Larger strand cross-sections are to be understood in particular those of more than 200 mm.
  • the result of a steel analysis the result of a steel analysis.
  • Temperatures of the molten metal in the tundish, in the casting mold amounts of cooling water for cooling the mold and the secondary cooling area and cooling water temperatures of the cooling water used to cool the mold and in the secondary cooling area.
  • a third software for the data transfer between the continuous casting machine and the first and the second software causes after switching on the first and the second Software for a fixed period of time, the target data for the continuous casting process are generated exclusively using data stored in the database.
  • the second software comprises a database with stored process data which subsequently simulates the course of a casting process carried out by means of a simulation or replay function.
  • the second software uses a modified simulation or replay function to reduce the dead time until the first software is used.
  • a device for measuring the strand length of the cast strand measures and that when a predetermined strand length is exceeded, the replay function can be switched on.
  • the invention is realized as a software solution for improving the functions of a known per se computer of a continuous casting with at least one continuous casting mold.
  • the invention may alternatively be in the form of an additional computer or one with additional memory equipped computer can be realized.
  • the invention also relates to a device for controlling the casting process in a continuous casting plant with a real-time controlling device for carrying out a method as described above.
  • the device according to the invention is characterized in that it has a high-speed computer for providing target data and process data in the initial phase of the casting process or when changing the metal to be cast or the metal alloy during the current casting process and that the controller instead of the real-time calculated data that of the Speed calculator provided data provided.
  • the device comprises a database with stored process data, wherein the high-speed computer by means of a simulation function (replay function) subsequently simulates the course of a casting process performed.
  • the process data stored in the database can be used during the initial phase of the casting process or during a change within the current casting process by the control device.
  • a casting process of a software 1 for generating target data for the process for casting the cast strand simultaneously with the software 2 calculating in real time, supplying all process data 3 from a cast strand 4 via a data interface 5.
  • the software 1 does not receive the actual casting speed, but the target casting speed and the target values stored, for example, in a cooling program that generates the data for cooling the strand.
  • the software 1 simulates the continuous casting process much faster than in real time and controls the setpoints within the simulation by changing the manipulated variables such as water quantity and casting speed. This makes it possible to provide the coolant quantities necessary in the casting process to reach the setpoint values as quickly as possible.
  • the software 1 determines a current correction factor 6 for the specific coolant application during the initial phase of the casting process; the correction factor 6 is forwarded via the interface 5 to the circuit part for calculation with the software 2. This then generates target data 7 for the amount of coolant, in particular the amount of water, and sends them via the interface 5 to the casting strand 4. All data is transmitted to a database 8.
  • the software 1 takes data 9 from earlier casting processes, which can be utilized for the control of the initial phase of the casting process currently taking place and which are delivered to the software 1 via the data interface 5. In particular, this is possible and necessary if, for example, due to an operating error, the computer system was not switched on for a while, with the exception of the data interface 5 and the software associated with the data interface 5. Then, when the computer is turned on, the software 2 first takes the necessary data from the database 8, which are provided via the data interface 5 available.
  • Modified replay functions allow the operator of the continuous casting plant to simulate castings that have been carried out in the past. This is done by means of the stored in the database 8 process data.
  • Another way to reduce rejects or quality degradation of continuously cast material is to use a modified replay function if the software 1 and / or software 2 of the computer were turned on too late.
  • the modified replay function makes it possible to reduce the dead time until the calculation process starts with the software 1, 2, in that the simulation is not performed in real time, but at maximum computing speed.
