Claims
- 1. A device for adjusting the secondary cooling of a continuous cast strand emerging in a longitudinal path from a continuous casting mold, to compensate for variations in the width of the strand surfaces comprising:
- (a) a strand guide support adjacent to and substantially surrounding said path;
- (b) a plurality of coolant spray nozzles positioned to define spray planes crossing said path;
- (c) elongated spray beams extending substantially parallel to said longitudinal path and adjacent thereto, said spray beams including at least one lateral spray beam positioned at a side of said path and upper and lower spray beams positioned above and below said path, respectively, and each of said spray beams forming a common support for a plurality of said spray nozzles;
- (d) pivot bolts on said strand guide support;
- (e) a plurality of guide levers, each of said guide levers pivotally attached to one of said pivot bolts on said strand guide support and to one of said spray beams, said pivot bolts having longitudinal axes being substantially transverse to the longitudinal axis of said path;
- (f) means associated with said strand guide support and said lateral spray beam for selectively adjusting and fixing the pivotal position of said guide lever attached to said lateral spray beam, whereby the pivotal position determines the distance of said spray nozzles supported on said lateral spray beam from said path, wherein said pivot bolts attached to said guide levers attached to said lateral spray beam are positioned on said strand guide support at an angle relative to the strand surface whereby said guide levers of said at least one lateral spray beam pivot around said pivot bolts in a plane forming an acute angle with the plane defined by the nozzles supported by said lateral spray beam, and said adjusting means displaces said at least one lateral spray beam transversely to and longitudinally along said path.
- 2. The device recited in claim 1 wherein said spray nozzles are spaced at progressively shorter distances from said path in the direction of the forward motion of the strand.
- 3. The device recited in claim 1 wherein said spray beams are subdivided into zones in the longitudinal direction of said path and at least two of said guide levers are provided for each of said spray beams of each of said zones.
