Description

Technical Field

[0001] The present invention belongs to the field of metal material preparation and processing, and in particular relates to a real-time dynamic simulation method and system for a continuous casting process. Background Art

[0002] Continuous casting (CC) is a widely used key technology for metal material preparation. During the continuous casting process, molten metal continuously flows into a mold, where it cools and solidifies under the action of the crystallizer. It is then continuously pulled out by the dummy bar, resulting in a metal billet of a certain size, providing raw material for subsequent deformation processes (such as rolling).

[0003] The temperature field during the continuous casting process determines the initial microstructure and properties of the metal material, significantly impacting subsequent processing and the final performance of the product. Currently, the primary method for analyzing the temperature field during the continuous casting process is finite element simulation, which then uses the trial-and-error results of the simulation to propose preset optimized process parameters. For example, Chinese patent CN116738518B proposes a numerical simulation method for the location of light-reduction cracks during continuous casting, as well as an internal quality control method. Through simulation and experimental verification, this method guides the setting of process parameters to reduce continuous casting microcracks.

[0004] However, finite element method-based temperature field simulations during continuous casting suffer from large numbers of grid nodes and strong nonlinearity, resulting in computational times of several hours. This makes the simulations suitable only for pre-design and post-analysis, and incapable of real-time simulation. Furthermore, traditional simulations are only suitable for steady-state temperature field analysis under fixed process parameters and are unable to simulate the dynamic changes in the unsteady-state temperature field during continuous casting. However, in actual production, only real-time dynamic simulation of the temperature field, tailored to the ever-changing continuous casting conditions, can achieve online intelligent control of the continuous casting process.

[0005] In order to solve the above problems, it is urgent to develop a real-time dynamic simulation method and related devices for the temperature field of the continuous casting process to realize the real-time dynamic calculation of the temperature field of the continuous casting process.

[0020] Further, the specific steps of S3) are:
