  • 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.

  • Apparatus for withdrawing solidified rod in horizontal type continuous casting machines
    Patent number: 4513806
    Abstract: An apparatus for drawing casting in a horizontal type continuous casting machine, which basically comprises a forward drive motor of a large capacity for driving a pair of pinch rollers in a forward direction with a large torque, a reversible constant-load motor for driving the pinch rollers in the reverse direction, a clutch for disconnectibly connecting the forward drive motor to the pinch rollers, a control circuit for engaging and releasing the clutch in response to output signals of detecting means which detect the forward and backward motions of the casting, respectively.
