Abstract

Non-free openings of steel casting ladles remain a significant challenge in the steelmaking industry, often leading to safety hazards and compromised steel quality. This issue primarily arises due to an incomplete understanding of ladle sands behavior during steel plant operations, hindering the optimization of ladle sands. This review outlines results from two studies conducted by PURMETALL and cooperation partners, addressing this problem through an in-depth analysis of ladle well filler sands. The studies focused on the interactions and thermochemical reactions between ladle well fillers and various steel qualities, as well as the correct methods of application. By examining these interactions under real operational conditions and controlled laboratory experiments, new insights are provided into ladle sands’ behavior in steelmaking processes. These insights will benefit the development of more effective ladle well fillers and application techniques, thereby improving free opening rates and the overall efficiency of steel production.
