The mechanism of inclusion removal from liquid steel by gas bubbling and bubble attachment in the tundish is complex due to the great number of variables involved, and it is even more difficult to study because of the turbulent flow conditions. The m

Turbulent flow when steel is delivered through a nozzle in a slab mold induces dragging forces at the metal–slag interface that entrain slag droplets into the metal bulk. These dragging effects are discontinuous and correspond to the velocity fluct

A mathematical model was developed to study effects of the vortex and the short circuit flow phenomena during tundish operation on the inclusion removal for a wide range of particle diameters. The model was solved using FLUENT® commercial software;

Modeling Study of Turbulent Flow Effect on Inclusion Removal in a Tundish with Swirling Ladle Shroud
Publikováno v:
steel research international. 80:223-234
The present study is focused on the assessment of a new concept of ladle shroud capable to control the turbulence promoted by the steel entry jet in a continuous casting tundish; the new proposal is a Swirling Ladle Shroud (SLS). It presumed that the

Non-metallic inclusion removal from liquid steel in a tundish is studied using two-phase flow modelling by Particle Image Velocimetry (PIV) techniques and mathematical simulation. The removal efficiency is studied as a function of Flow Control Device

Transient fluid flow behavior in a tundish with two different arrangements, a bare tundish and a tundish using flow control devices, was studied using physical modeling and a mathematical model. The study places special emphasis on buoyancy effects,

Steel flow dominated by inertial and buoyancy flows under gas bubbling and thermal stratification conditions, in a one-strand tundish, was studied using a 2/5 scale water model. The use of a turbulence inhibitor yields plug flow volume fractions well

In order to optimize steel flow and maximize the contact time of the inclusions with the slag layer inside the tundish, a proper flow-control arrangement must be designed, considering the shape, the dimensions of the prototype, and the plant operatin
