BACKGROUND ART Generally, in continuous casting, a slab discharged from a mold is cooled and solidified by cooling water from a plurality of cooling water nozzles arranged in the direction of movement of the slab and the width direction of the slab. By the way, since there are many different widths of slabs, it is necessary to adjust the spray width of cooling water according to each slab. Conventionally, when adjusting the spray width, this was done by cutting off the cooling water supply to the outer nozzles, but this did not allow for optimal cooling for other types of slab widths, such as corners. It was not possible to prevent overcooling of the parts. Usually, the jetting characteristics of a nozzle vary depending on the amount of water and the height of the nozzle, and the water amount distribution does not become completely similar under any conditions. In particular, areas where sprays from adjacent nozzles overlap tend to become uneven. As a solution to this drawback, for example, JP-A-59-
There are those shown in Japanese Patent Application Laid-open No. 147758 and Japanese Patent Application Laid-Open No. 178158/1983. In the former type, sub nozzles are arranged on both sides of the main nozzle, and the amount of water in both nozzles is controlled separately according to the width of the slab.
In the latter type, the height of the nozzle can be adjusted according to the width of the slab.

Problems to be Solved by the Invention According to the former method, there is a problem in that the amount of water in both nozzles must be controlled separately. Also, according to the latter, when the slab width becomes wider,
Since the amount of water from the nozzle is increased and the nozzle position is raised, there is a problem in that the cooling water is applied to the rolls and adversely affects the cooling of the slab. One possible solution to the above problem is to arrange multiple nozzles in a staggered pattern, but if the nozzles are moved vertically and horizontally depending on the width of the slab, the staggered arrangement requires a complicated structure. As the size increases, placement within a narrow segment becomes difficult.

l=h [tan (θ 1 /2) + tan (θ 2 /2)] In the above configuration, when cooling water is supplied from the cooling water supply pipe 11 to the nozzle headers 7A, 7B, 7C, the cooling water is supplied from each nozzle 4A, 4B. is uniformly distributed on the slab 2. In particular, since the two types of nozzles 4A and 4B with different spray angles are arranged alternately, the ink is evenly distributed. And the wide slab 2
When changing from A to narrow type 2B, each worm jack device 16A, 16B, 16C is moved by an electric motor.
is driven to move the center nozzle header 7A downward, and move the left and right nozzle headers 7B, 7C to the center side and downward. At this time, the nozzles 4A and 4B are moved so that their ejection ranges do not overlap. Therefore, even if the width of the slab 2 becomes narrow, the cooling water is uniformly injected, and, for example, overcooling of the corner portions does not occur. Note that the left side portions of FIGS. 1 and 2 show a case where the slab width is wide, and the right side portions show a case where the slab width is narrow.

Incidentally, in the above embodiment, the nozzle headers are arranged in three rows, that is, the nozzle groups are arranged in three rows; for example, two rows may also be used.Although the nozzle groups are shown on the upper surface of the slab, it is of course possible to arrange them similarly on the lower surface. Moreover, all position adjustments are made using the same electric motor.
