摘要： Method and apparatus for continuous casting, especially casting of steel that can 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 surface position of the upper portion of molten metal) to the crater end (a final solidification position), 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 casting speed, casting temperature and cooling conditions, with special attention paid to the pressure drop of liquid phase induced by the liquid flow between dendrites resulting from 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 and their positions, and finally by applying an electromagnetic body force (Lorentz force) in the casting direction in the vicinity of the region where the internal defects are formed.

摘要： A method of detecting defects in materials using infrared thermography, includes placing the rear surface of an object to be inspected close to the front surface of a thermoplate controlled by a temperature controller, and the front surface of the object in a vacuum chamber. At the other end of the vacuum chamber, on the outside, an infrared camera is arranged facing the object, so that a vacuum is maintained between the object and the camera. Defects are detected from thermal images of the object, obtained with the infrared camera.
