Abstract

PURPOSE: To obtain cast steel pieces having excellent surface properties, by heating only the upper portion of the molten steel contained in the mold from the outside at continuous casting processes.
CONSTITUTION: Only the upper part of molten steel contained in mold 2 is heated with an outside heat source, and the temperature near the interface between the molten steel and flux is raised and fluidity of that part is improved. By this, cast steel pieces which are manufactured by continuous casting and which has excellent surface properties and contains less amount of flux and other oxides, are obtained. A high frequency induction heating using flat type spiral coil 1 is the most suitable heating means. The coil must be installed within a distance of 150mm (most desirable distance is less than 100mm) and it is recommendable to install the coil near the central part of width of the cast steel piece where temperature of molten steel is lowest.
