Abstract:
In this paper will be presented the improvement in the superficial quality of high manganese steel applied in the continuous casting of slabs, during the use of spherical mold flux with the addition of manganese oxide. This flux was developed in the laboratory and its performance was evaluated in the mold of the continuous casting slab machine. The results of the laboratory development of the mold flux and the data collected during application of the product will be presented and elucidated, considering the main variables in the continuous casting that influence the mold flux's behavior. It was possible to adapt the mold flux to the performance needs in the mold and achieve good results of surface quality
