Abstract：In view of the features of producing nonoriented electrical steel by thin slab continuous casting and mold powder to be weed, the relationship between the physical and chemical properties of mold powder and the carbon pickup of nonorientated electrical steel and heat flux of the mold was revealed. Results show that carbon pickup from the flux can be effectively avoided by reducing the carbon content of mold powder, and controlling the thickness of liquid flux in a range of 5～10 mm. The heat flux of the mold can be increased by reducing the basicity and the melting point of mold powder. Finally, a new mold powder with good physical and chemical properties was developed, which can realize the stable heat fuex of the mold,prevent the carbon pickup from the mold powder and obtain the nonoriented electrical steel coils with good surface qualities.
