ABSTRACT:
A guide roll assembly associated with a continuous caster supports both faces of a dimensionably unstable metal strand at it solidifies and cools. A frame segment has a first frame member operatively connected with movable second frame member. The first frame member supports first guide rolls and stops. The second frame member supports second guide rolls and also rotatable cams. An anchor clamped with the stops, anchors the cams to the first frame member when a piston cylinder clamps the anchor against the first frame member to establish a nominal roll gap dimension. Motors rotate the cams to reposition the second frame member and the second guide rolls mounted on it and thereby adjust the nominal roll gap dimension. Frame segments can be oriented by camming to provide a taper line to contact both faces of a shrinking strand or to perform a soft reduction upon it.
