摘要： A porous layer consisting of sintered material containing metal powder or ceramics powder is provided as the inner surface of a mold for use in continuous metal casting, and a shielding plate is provided on the outside of this porous layer. A gas is supplied in a gap portion formed between the porous layer and the shielding plate and the gas is spouted out from the porous portions in the porous layer into the inside of the mold, thereby forming a gas film between the inner surface of the mold and the molten metal. Electromagnetic coils are interposed between a stiffening plate and sandwiching frames around the mold and hanger frames supporting them. An annular cylindrical partition wall surrounding a nozzle is provided between the mold and a tundish, and a water-cooled reflecting plate having an annular downward reflecting surface is also provided therebetween.

摘要： A method and apparatus of continuous casting with the use of a mold oscillating system adapted to oscillate a casting mold supported by a oscillating frame, the method including oscillating the mold by applying vibration at a preselected frequency higher than the natural frequency of the oscillating system; and increasing the amplitude of applied oscillation to a value in a range as determined by the ratio of a length of time of a downward movement period of the mold to a time length in which the speed of the mold exceeds the casting speed during the downward period. Preferably the preselected frequency of applied oscillation of the mold is approximately 1.5 times higher than the natural frequency of the oscillating frame.
