Analysis of Secondary Cooling Solidification Process of Continuous Casting Slab Based on Finite Element Method

The rationality of cooling process in continuous casting process is closely related to the quality of slab, which has important practical significance for the research and optimization of secondary cooling process in continuous casting process. Taking an alloy medium carbon steel as the research object, the transient heat transfer model of secondary cooling solidification of continuous casting slab is established by using the finite element software ANSYS, and the reliability of the model is verified by comparing with the measured values. On this basis, the temperature field and shell growth of continuous casting slab under different casting speeds and spray water volume are simulated and analyzed. The research results provide theoretical support and help for further improving the slab production quality and guiding the production process.
