In this paper, we investigate the kinematic mechanism and path planning of a two-caster nonholonomic vehicle (the Essboard) which is a recent variant of skateboards. Different from the most studied Snakeboard, the Essboard consists of a torsion bar and two platforms, each of which contains a pedal and a caster. We study the relationship between the tilt angle of the pedal and the wheel directio...

The paper discusses a 3D numerical solution of the inverse boundary problem for a continuous casting process of alloy. The main goal of the analysis presented within the paper was to estimate heat fluxes along the external surface of the ingot. The verified information on these fluxes was crucial for a good design of a mould, effective cooling system and generally the whole caster. In the study...

Abstract A model of turbulent multiphase flow, heat transfer, and particle entrapment during continuous casting steel is presented. The includes the top 7m vertical curved strand, considers effects argon gas injection thermal buoyancy. RANS flow results are compared with LES. Lagrangian transport through Eulerian-Eulerian field from k -ɛ based on random walk features advanced capture criteria, ...

Three-dimensional finite-volume-based numerical models of fluid, heat, and mass transport have been developed and applied to help explain the complex inter-related phenomena of multiphase fluid flow, superheat dissipation, and grade intermixing during the continuous casting of steel slabs. Gas bubbles are simulated using a continuum model, which calculates the volume fraction and velocities of ...

Tool steel for hot working is usually used the rolls of conventional twin-roll casters aluminum alloys. In a vertical high-speed caster, copper are to rapidly solidify alloys and increase casting speed, since thermal conductivity higher than that tool steel. However, degree superiority over not clear. present study, effect roll material on strip solidification between caster was investigated by...

Transient flow during nominally steady conditions is responsible for many intermittent defects during the continuous casting of steel. The double-ruler electromagnetic field configuration, or ‘‘FC-Mold EMBr,’’ is popular in commercial slab casting as it provides independent control of the applied static field near the jet and free surface regions of the mold. In the current study, transient flo...
