摘要： Method and apparatus for continuous casting, more particularly continuous casting of steel that can easily provide steel of good quality that has no central segregation and central porosity. In other words, in the method and apparatus, central defects are to be eliminated by identifying the solidifying conditions in the full range from the meniscus (the surface position of the upper portion of molten metal) to the crator end (a final solidifying position), and more particularly the pressure drop of liquid phase caused by the liquid-phase current between dendrites induced in turn by the solidifying contraction in a casting direction in the solid-liquid coexisting phase based on the operating conditions such as the type (profile) of continuous casting machines, type of steel, cross-sectional configuration/size of a cast piece and casting speed, casting temperature and cooling conditions, calculating conditions causing internal defects and generated positions, and applying an electromagnetic volume force (Lorentz Force) in the casting direction in the vicinity of the positions where the internal defects are generated.
