Abstract: The thermal history of the mold flux in the crystallizer was analyzed to understand the specific role of the mold flux in the crystallizer. At the same time, the melting characteristic, crystallization characteristic and rheological behavior characteristic of the protective slag under electromagnetic field were analyzed, and the influence of Joule heat generated by electromagnetic field was analyzed. It provides a reference for the systematic study of the metallurgical properties of the protective slag under electromagnetic field and further theoretical research.

Key words: electromagnetic continuous casting, mold powder, electromagnetic field, metallurgical properties
