Abstract
A cast piece guide roll segment in continuous casting equipment having a curved cast piece guide path which is used in the structure for supporting the roll groups in the respective curved portions for guiding the cast piece leaving the mold along the curve between the vertical and horizontal paths. In view of the problems inherent in continuous casting equipment such as the need for frequent roll changes and emergency shut-downs, the roll segment disclosed includes roll units having at least a pair of rolls and bearings provided at opposite ends thereof and removable from a frame, on which frame are mounted pivotable caps for holding roll units.
Claims4
A cast piece guid roll segment in continuous casting equipment comprising:
- roll units rotatably supporting at least a pair of rolls with the interval between opposing rolls being variable;
- a frame having an aperture defined on the top thereof for removal and insertion of said roll units;
- caps pivotably mounted on said frame and movable between a first position, at which said aperture is entirely uncovered and opened so as to permit said removal and insertion of said roll units through said aperture, and a second position, at which said aperture is covered so as to prevent the removal of said roll units and to press said roll units downwardly through said aperture, and through intermediate positions for varying said interval between said opposing rolls;
- and
- a cap drive mechanism for pivotal movement of said caps, and capable of being held by a force sufficient to hold the rolls at any position corresponding to the pivoting position of said caps.
