Method for continuous casting of steel
 In a method for continuous casting of steel, an improvement which is constituted by carrying out the continuous casting process while the thickness of a molten mold powder pool adjacent to the molten steel melt within a continuous casting mold is maintained at a desired preset value, and whenever the actual value deviates from the preset value, the continuous casting can still be continued by adjusting the casting conditions or by selecting a powder appropriate for the casting conditions. The method produces a casting requiring no subsequent processing to remove defects.
