Abstract
A mold oscillator for a continuous casting machine in which a mold is mounted for vertical reciprocation on a mold table frame, the machine having an enclosed spray chamber beneath the mold for spray cooling of a continuous casting therein as it emerges from the mold, in which an oscillator cam connected to a drive motor is connected through a yoke to first and second vertical shafts fixed to the mold table frame at their upper ends, and are seated within and vertically oscillatable within tubular guide means and ball bushings therein, which control the alignment of the shafts, thus reducing horizontal vibration and strand misalignment.
Claims14
In a continuous casting machine in which a mold is mounted for vertical reciprocation on a mold table frame, said machine having an enclosed spray chamber beneath the mold for spray cooling of a continuous casting therein as it emerges from said mold, an improved mold oscillator mechanism comprising;
- a drive motor;
- an oscillator cam connected to said drive motor;
- first and second vertical shafts fixed to said mold table frame at their upper ends;
- and
- means connected to said shafts for imparting vertical oscillatory motion to said shafts through said cam;
- first and second vertical oscillator shaft guide means, said first and second shafts being seated within and vertically oscillatable within said guide means;
- each vertical oscillator shaft guide means comprising a vertical tube having at least a pair of vertically spaced bushings with said tube for seating, guideing and controlling the alignment of said shaft within said tube;
- and an upper tube cover plate fixed to the upper end of said tube and being provided with a central hole therethrough adapted for receiving said shaft therein.
