Abstract
An apparatus for grinding a continuously cast slab having a longitudinal axis and a rectangular cross-sectional shape with two opposite wide faces and two opposite narrow faces apparatus has a frame, two transversely spaced grinders carried on the frame, and a holder having two transversely spaced grippers engageable with the opposite faces of the slab in a vertical position with the wide faces of the slab vertical for grinding of the wide faces of the slab by the grinders and in a horizontal position offset by 90° to the vertical position with the wide faces of the slab horizontal for grinding of the narrow faces of the slab.
Claims14
An apparatus for grinding a continuously cast slab having a longitudinal axis and a rectangular cross-sectional shape with two opposite wide faces and two opposite narrow faces, the apparatus comprising:
- a frame;
- two transversely spaced grinders carried on the frame;
- and
- a holder having two transversely spaced grippers engageable with the opposite faces of the slab in a vertical position with the wide faces of the slab vertical for grinding of the wide faces of the slab by the grinders and in a horizontal position offset by 90° to the vertical position with the wide faces of the slab horizontal for grinding of the narrow faces of the slab.
The grinding apparatus defined in claim 3, further comprising:
- actuator means engaged between the holder frame and the one beam for shifting the beams transversely toward and away from each other.
An apparatus for grinding a continuously cast slab having a longitudinal axis and a rectangular cross-sectional shape with two opposite wide faces and two opposite narrow faces, the apparatus comprising:
- an outer frame;
- an inner frame pivotal about a horizontal and longitudinally extending axis on the outer frame;
- two transversely spaced grinders;
- a longitudinally extending upper holder beam in the inner frame carrying a respective center row of grippers;
- a longitudinally extending lower holder beam in the inner frame carrying a respective center row of grippers;
- two outer rows of grippers on one of the holder beams flanking the respective center row of grippers, the outer rows of grippers being shiftable on the one holder beam between a retracted position transversely outward of the respective center row of grippers and an advanced position transversely inward of the respective center row of grippers;
- a first actuator for shifting the beams transversely toward and away from each other;
- a second actuator for transversely shifting the holder beams on the inner frame transversely toward and away from each other and thereby gripping the slab in either of two 90° offset positions with the two outer rows of grippers in the advanced position for gripping the slab by the wide faces and with the two outer rows of grippers in the retracted position for gripping the slab by the narrow faces.
