で掬い上げられ排水へラダ６に至り機外へ排出される。FIG. 1 shows a belt cooling system of a typical conventional belt-type continuous casting machine, which includes a water supply header 4, a scoop 5,
This is an open type cooling device whose main components include a drain header 6 and a drainage header 6. The static pressure of the molten steel 9 acting on the belt is supported by the knife edge support disk 6, and the cooling water that promotes solidification of the molten metal is jetted out from the water supply header 4 to cool the belt 2 (indirectly ) and scoop 5
It is scooped up and sent to the drainage system, reaching rudder 6, where it is discharged outside the machine.

冷却水圧力、即ち、ベルト２の支持力が小さい。従って
ベルト２は金属静圧により冷却水側に大きぐ膨らみ、そ
れにつれ鋳片１も膨らむこととなる欠点を有している。By the way, when increasing the size of the equipment or increasing the height of the machine, the molten metal static pressure acting on the bell 2 increases proportionally as the size increases. In a conventional continuous casting machine having an open type cooling water system as shown in FIG. Therefore, the belt 2 has the drawback that it swells considerably toward the cooling water side due to metal static pressure, and the slab 1 also swells accordingly.

点が生ずる。In addition, in order to ensure the necessary cooling capacity of the cooling water jetted from the rudder 4 to the water supply, it is necessary to form an appropriate cooling water flow rate and water layer thickness, but there is no mechanism to compensate for these. However, it has drawbacks such as the need for a large amount of cooling water. In other words, the molten metal static pressure belt support means and cooling means of the conventional belt-type continuous casting machine do not pose any problem in use when the equipment is horizontal or has a small inclination angle, or when the production capacity of the equipment is small. The above-mentioned drawbacks occur when it becomes necessary to increase the height of the machine and also to increase the production capacity of the equipment.

連続鋳造機のベルト冷却装置である。The present invention, as a means for achieving the above object, consists in providing a belt cooling device with a plurality of sealed compartments so that the cooling water pressure can be adjusted for each compartment. That is, the present invention provides a continuous straddling machine having a mold belt cooled by a belt cooling device, in which the belt cooling device is divided into a plurality of sealed sections by a large number of partition plates, and the cooling water pressure can be adjusted for each section. This is a belt cooling device for a belt-type continuous casting machine that is characterized by the following characteristics:

The water pressure inside the cooling device can be adjusted to an appropriate value 1c in accordance with the pressure distribution, and the required cooling effect can be obtained with a small amount of cooling water.

Adjust the water pressure (belt support pressure) to the appropriate value! It becomes possible to make one knot, thereby suppressing the bulge of the belt and the cast piece toward the cooling water side. Furthermore, by providing a partition plate that forms a cooling water flow path, the interval (water channel) between the partition plate and the belt can be appropriately determined.
With a relatively small amount of cooling water, it is possible to obtain the cooling water flow rate and water layer ring necessary for cooling the belt, and it is also possible to prevent excessive overheating of the belt. Furthermore, in belt-type continuous casting machines, cooling in the mold (-
(sub-cooling) is important, and the present invention particularly has the effect of increasing the cooling intensity and uniformly cooling.
