  • Method and apparatus of continuous casting by the use of mold oscillating system
    Patent number: 4577277
    Abstract: 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.
