Abstract
PURPOSE: To improve the quality of the one having been cast first by heating the mold and molding board to be used for the first ingotting prior to pouring at the time of casting molten rimmed steel into a top pouring mold.
CONSTITUTION: Since the rimmed steel ingot obtained by the mold used for the first ingotting becomes a product of poor quality, the mold temperature is raised up to a predetermined temperature just before casting to prevent the drop in molten steel pouring temperature. For example, at the time of casting molten rimmed steel into the molds to used for the first and subsequent order, the temperature is so controlled that its pouring temperature becomes 1555°C. Said first mold is heated for 30 minutes by using a burner to heat the mold inside and the molding board, after which casting is performed. As a result, the rimming decision of the steel ingot is middle and the results of the formation of super flaws of this steel plate becomes good, thus the defective steel ingots are eliminated at all.
