Importance of Simulating the Steel Flow Process in the Tundish, on the Quality of Continuously Cast Slabs
Keywords:
tundish, simulation, mathematical modeling, steel quality
Abstract
The benefits of using mathematical modeling of the flow are obvious, the final objective being the elimination of as many inclusions as possible during the flow of steel through the tundish, and thus, obtaining steel with superior quality.
In this work, a simulation of the movement of the liquid alloy in the tundish was carried out, in order to highlight the erosion of its refractory lining. For this, we used SolidWorks, RealFlow, and ABAQUS programs.
Using these simulation programs, the filling method of the tundish, the contact area of the alloy jet with the tundish wall, and the "dead" areas are highlighted, as well as the turbulences that can appear during the flow, which have a negative impact on the quality of the steel.
