Research on the On‐Line Simulation of a Three‐Dimensional Temperature Field Model of Slab Continuous Casting

Abstract: Based on the two-dimensional heat transfer and solidification model, the differences in heat transfer boundary conditions in the casting direction and width direction of a slab are researched, and the results are verified by experiment. By using the method of "limited thickness slice unit", the numerical discretization of each slice unit in the computational domain space is carried out in real time, and the casting information of all the slice units in the slab is tracked in real time, which achieves the effec… Show more

“…The developed model of this study is sufficient for commercial use. The first, the surface temperature of cast steel during the continuous-casting process differs by ∼50°C at the same position [50] due to differences in such factors as equipment configuration and control. However, the temperature error range of the developed model is <50°C.…”

“…There are several techniques for measuring solidified shell thickness directly, such as: nail shooting, tracer dispersion, breakout event and wedge test. Nail shooting technique consists of the insertion by pressurized air of a nail in the strand in solidification, in the remaining liquid steel, a FeS2 tracer is added to facilitate visualization after preparation [1][2][3][4][5][6]. Nail shooting has high acceptance due to the high frequency of successful tests, however it requires a considerable infrastructure to be assembled.…”

“…The gap between the slab heaters was increased and not covered, so the slab temperature rapidly dropped when the slab was passed through the slab heater. In the steel-fabrication process, the temperature distribution is the most important parameter determining slab quality [4][5][6][7][8][9][10][11]. Temperature distribution also affects the kinetic and kinematic parameters, such as stress, strain, and deformation, which are directly related to quality [12,13].…”
