摘要：Method and apparatus for continuous casting, especially casting of steel thatcan easily provide high quality steel that has no central segregation and central porosity.In other words, in the method and apparatus, central defects are to be eliminated first by

identifying the solidifying conditions in the full range from the meniscus (the surfaceposition of the upper portion of molten metal) to the crater end (a final solidificationposition), based on the type (profile) of continuous casting machine, type of steel, cross-sectional shape and size of a cast piece and the operating conditions such as castingspeed, casting temperature and cooling conditions, with special attention paid to thepressure drop of liquid phase induced by the liquid flow between dendrites resultingfrom the solidification contraction in casting direction in the solid-liquid coexisting zone,second by calculating the condition of the formation of the above internal defects andtheir positions, and finally by applying an electromagnetic body force (Lorentz force) inthe casting direction in the vicinity of the region where the internal defects are formed.
