Figure 3 is a vertical cross-sectional view perpendicular to the long side of the slab of a conventional belt-type continuous slab casting machine, and Figure 4 is a vertical cross-sectional view of the slab of a conventional belt type continuous slab casting machine.
It is a FF line arrow view of a figure. The conventional continuous casting machine shown in FIG. 3 and FIG. The main components are a nozzle 5 and a side block 9. The side block 9 is fixed and serves to prevent the molten steel from flowing out laterally between the belts 2, and forms one side of the mold.

配設されている。 The molten steel from the tundish 4 is passed through the nozzle 5 to the belt 2.
Then, pour the metal into the mold formed by the side blocks 9. The back side of the belt 2 is cooled by the spray 8 from the spray nozzle 7, which indirectly cools the molten steel in the mold, solidifies the molten steel, and casts the slab 1, which is then pulled out by the drawing pinch rolls 3'. It will be destroyed. In addition, in FIG. 3, 1' is the upper surface of the molten steel, that is, the meniscus. In addition, since there is molten steel between the belts 2, static pressure (molten steel pressure) corresponding to the height of the belt 2 is applied to the belt 2, and a back-up roll is applied to support the static pressure (molten steel pressure) between the belts 2. 6 are arranged. Further, as shown in FIG. 4, the side block 9 is provided with a cooling water passage 10 in order to cool the side block 9 and indirectly cool and solidify the side of the molten steel. A fixed presser block 11 for pressing the belt 2 against the side block 9 is provided.
