An Overview of Ladle Refractory Design Optimizations Through CFD Modeling

Ladle refractory is critical to ensure stability of the secondary steelmaking process. From loading to teeming, computational fluid dynamics (CFD) simulations allow for the investigation of how molten steel flow influences operational aspects of the ladle, such as refractory wear, mixing efficiency and slag carryover to the tundish. This paper presents three different studies, each one approaching one step of the ladle operational cycle (loading, purging and teeming). The aim is to showcase how CFD simulations are able to enhance ladle refractory design, potentializing its lifespan, increasing the secondary steelmaking process efficiency and reducing steel production costs.
