Definitions
- This invention relates to an apparatus for oscillating a mold for curved-type continuous casting machines, and more partiuclarly to an apparatus for oscillating a mold having a small radius of curvature.
- the invention as claimed provides:
- An illustrated apparatus of the invention is basically a single lever type constriction to ensure motion along a perfect circular arc, and comprises a base frame of adequate rigidity, an oscillation lever mounted at its fulcrum on said base frame, a cam mechanism for oscillation mounted on said base frame, and a drive motor mounted on said base frame, said base frame being detachably mounted on a structure which in turn is securedly supported on a concrete foundation.
- An apparatus according to the present invention can be advantageously incorporated into a curved-type continuous casting machine having a small radius of curvature since it becomes compact in construction due to the fact that the length of the oscillation lever is reduced with smaller radius of curvature.
- the oscillation lever has its center of oscillation corresponding to the center of curvature of a mold, so that the mold oscillates about the center of curvature to provide an accurate circular arc, thereby saving the trouble of locating the center of curvature of the mold anywhere on the building where the continuous casting machine is mounted.
- the center of curvature of a mold is immune from any displacement which would be caused by distortion of the building in the prior art, so that the mold can oscillate along an accurate circular arc.
- a mold having its center of curvature fixed thereto can be attached to a continuous casting machine only by mounting a base frame on a structure, and various elements prvoided on the base frame can be completely repaired at a location away from the continuous casting machine to improve an efficiency of repair work.
- an apparatus for oscillating a mold 1 of a curved-type continuous casting machine (not shown).
- the apparatus is generally designated by numeral 10, and comprises an oscillation lever 2 for the mold 1, a base frame 3, a bracket 4 secured to said base frame, an oscillation cam shaft 5 rotatably mountd on said base frame, an oscillation drive lever 6 oscillatorily mounted on said cam shaft, a reduction gear 7 for oscillation drive, and a drive motor (not shown).
- These components constitute an integral oscillation unit.
- the mold 1 has a path la for cast strands, which path has a radius of curvature R, and is detachably secured to the oscillation lever 2 by bolts 11 such that a center O 1 of curvature of the path la corresponds to a fulcrum at which the oscillation lever 2 is pivotally mounted on the bracket 4.
- the oscillation lever 2 is also pivotally attached at a loading point 0 2 to the oscillation drive lever 6 to oscillate about the fulcrum, that is, the center O 1 of curvature.
- the loading point 0 2 is located on a line passing through the center O 1 of curvature.
- the oscillation drive lever 6 is swingingly driven by the oscillation cam shaft 5 which is in turn driven by the drive motor (not shown) through the reduction gear 7 for oscillation drive.
- the oscillation unit thus constructed is provided at the underside of the base frame 3 with a plurality of positioning liners 3a, through which the unit is positioned on top support surfaces 8a of a structure 8 and is detachably secured to the structure 8 by means of cotter pins 12.
- the structure 8 is rigidly mountd on a concrete foundation 9.
