Numerical modelling of fluid flow and macrosegregation in a continuous casting slab with asymmetrical bulging and mechanical reduction

Numerical Investigation for the Influence of Turbulent Heat Transfer of Mushy Zone on Shell Growth in the Slab Mold

“…Recently, the flow, heat transfer and macrosegregation in the mushy zone during solidification have been studied using numerical simulation. 4,[18][19][20][21][22][23][24][25] However, the influence of turbulent heat diffusion in the mushy zone on the formation of the impinging zone has been rarely reported.…”

“…In the past few decades, many researchers have studied the growth of the shell by numerical simulations. However, several researchers [3][4][5][6][7][8][9] did not consider the influence of the jet in the mold on the growth of the shell, and a parabolic curve of shell growth was obtained. Huang et al 10) and Yu et al 11) simulated the superheat removal in the slab mold respectively, and the results showed that the heat flux was highest at the impact point, which could affect the growth…”

A Model-Based Predictive Controller of the Level of Steel in the Mold with Disturbances Using a Repetitive Structure

“…The control of the level of steel in the mold is very important; it affects the quality of the steel produced related to mechanical and metallurgical properties, such as center segregation and absence of surface marks, cracks, inclusions, porosity, and other defects, and, consequently, affects its commercial value [2][3][4]. The quality of the steel depends on the degree to which a predetermined liquid steel level can be kept within a specific range (setpoint) during the many stages of the process.…”

In Situ Observations and Microstructure Evolution Behavior of Static Recrystallization of Microalloyed Continuous Casting Slabs in a Solidification End Reduction Process

“…Taking advantage of the large temperature gradient at the solidification end of the billet results in efficient transfer of deformation from the surface to the core, significantly improving the density and homogeneity of the billet. [3,4] During the HR process, continuous recovery and recrystallization inevitably appear in continuous casting slabs or blooms, which refines the microstructure and affects the final mechanical properties of rolled products.…”
