A three-dimensional coupled flow and heat transfer model of the mold copper plate–steelSteel melt system for ultra-large beam blank casting was developed using ANSYS to analyze different cooling slot configurations. Results show that uniformly distributed slots cause excessive cooling at wing-tip corners and insufficient cooling in R-corner regions, leading to poor circumferential uniformity of slab surface temperatureTemperature and shell thickness. To address this, optimized designs—removing wing-tip corner slots and densifying R-corner slots—were proposed. The optimized scheme reduced the maximum wide-face copper plate temperatureTemperature difference from 68.1 ℃ to 23.4 ℃ and decreased circumferential shell thickness variance from 27.7 mm2 to 17.5 mm2. These improvements enhanced heat transfer uniformity, promoted stable slab solidificationSolidification, and prolonged copper plate service life, providing theoretical guidance for mold cooling structureMold cooling structure optimization in ultra-large beam blank continuous castingContinuous casting.
