Transient Fluid Flow Phenomena during Continuous Casting: Part II—Cast Speed Change, Temperature Fluctuation, and Steel Grade Mixing

Abstract: where H is enthalpy or heat content in J/kg, k is thermal conductivity in W/m · K, and T is the temperature in K.Particles were modeled using both Eulerian and Lagrangian approaches. The Eularian approach considers them as continuous phase, whereas the Lagrangian approach treats them as a discrete phase.16) Due to the low volume fraction of particles, the Lagrangian approach is always used to calculate the trajectory of particles by considering the force balance acting on them 17) ......... (2) where u Pi is p… Show more

“…In ideal circumstances, fluid flow pattern inside the mold is symmetrical along the central plane. However, in the actual production process, the fluid flow and the surface velocity become asymmetric due to turbulence, slide‐gate or stopper‐rod misalignment, nozzle clogging, and cast speed change . Asymmetric flow causes transient fluctuations, leading to product defects .…”

“…Therefore, in order to understand the steel CCC process of round billets, mathematical modeling of the fluid flow phenomena is a feasible choice. Many turbulent models and multiphase models have been used for the fluid flow in gas-stirred steel refining processes [10][11][12] and steel continuous casting processes [13][14][15][16][17][18][19][20][21][22][23] , as summarized in Table I. However, so far very few investigations on CCC process were reported.…”

“…To describe transient flow phenomena, modeling techniques, both physical and numerical, are broadly used, also involving the description of dispersed inclusions path in the steel to estimate their surface floatation tendency 12–22. Water modeling has the advantage of representing in an impressive and immediate way the main flow features, by means of tracers.…”
