Figures 3 and 4 are diagrams showing an example of the water-cooled box structure of this continuous thin plate casting machine. It is a figure which shows the E-E cross section. Reference numeral 1 denotes an endless belt which is stretched between a plurality of pulleys (not shown), and travels in the direction of arrow 3 in FIG. 4 and returns in the direction of arrow 10, forming an endless belt.

1 and the lower roller 12 with a force of P, and runs in the direction of arrow 3. 6 is a water-cooled box, and 8 is a roll with fins provided in the water-cooled box. The finned roll 8 supports the belt 1, and cools the belt 1 by letting the cooling water 7 flow into the gaps between the fins as indicated by the dotted arrow. The molten metal 4 is poured into the space formed by the belt 1 and the short side wall 2 behind the arrow 3, but it is cooled and solidified while being conveyed on the belt 1, and a thin plate is formed in front of the endless belt 1 in the direction of the arrow 3. It is continuously extracted as slabs.

が発生する。 It is desirable that a continuous thin plate casting machine be able to produce thin plate slabs of various sizes with different slab widths. However, in the conventional thin plate continuous casting machine, which produces a thin plate slab of width W as shown in Fig. 3, for example, the short side wall 2 is moved to the position indicated by the dotted line.
When producing a thin slab of width W′, the following problems occur.

第５図は従来の薄板連鋳機により鋳片を広巾Ｗ
から狭巾W′に変更した際の状況を示す図である。 Figure 5 shows a conventional thin plate continuous caster casting slabs into a wide width W.
FIG. 4 is a diagram showing the situation when the width is changed from W to narrow.

となり、操業の継続が困難となる。 For example, the short side blocks 2-1 and 2-3 in FIG. 5 are supported by the finned rolls 5 and 8, so they do not shift even if they are pressed by the force P. However, the short side blocks 2-1 and 2-3 in FIG. 2-2 is located between the finned rolls 5 and 8 and is not supported at the bottom, so when pressed by the force P, the belt 1 is pushed down and the belt 1 is displaced. When the short side blocks are misaligned, a gap 14 is formed, but when molten metal is poured into this gap 14 and solidifies, it becomes cast, making it difficult to continue the operation.

The purpose of the present invention is to provide a water-cooled box having a supporting device that does not cause hot water or casting even when the water-cooled box is heated.

りを生ずることがない。 Figure 1 is a diagram showing the water-cooled box of the present invention.
The figure shows the manufacture of wide sheet slabs with a width of W.
Figure B is a diagram showing the production of a narrow thin plate cast side with a width of W'. In the figure, reference numerals 9 and 9' denote fixed skids arranged in the direction of movement of the belt 1, respectively. The fixed skids 9 and 9' can be provided with cooling water jet holes and discharge holes as necessary, but the size of these holes is usually set to be sufficiently small compared to the length of the short side block 2. As soon as possible, increase the pressing force P in Fig. 1 B.
Even if the short side block is added, the short side block will not shift and cause hot water or casting.

操業を継続することができる。 In Figure 1, the width of the thin plate slab to be manufactured is determined from W.
When changing to W', the short side wall 2, the upper roller 11,
The short side presser 13 is shifted inward to change the setting from the state shown in figure A to the state shown in figure B. In the state shown in Figure B, the belt 1 and the short side wall 2 run while being sandwiched by the upper roller 11 and the fixed skids 9, 9' with a force of P. At this time, since the fixed skids 9 and 9' are beam-shaped and support the belt 1 evenly in the length direction, deformation of the belt 1 or displacement of the short side blocks may occur as explained in FIG. Therefore, there is no need for pouring or pouring, and stable operation can be continued.

うに選定するとよい。 In addition, when selecting the length l ₁ of the finned roll 8 and the width l ₂ of the fixed skid in Fig. 1, (l ₁ + 2l ₂ )
corresponds to the maximum width of the thin plate slab to be manufactured,
In addition, l ₁ is preferably selected to correspond to the minimum width of the thin plate slab to be manufactured.

る。 FIG. 2 is a diagram showing an example of a continuous thin plate casting machine using the twin belt method. Although the present invention has been explained using a continuous sheet casting machine using a single-sided belt method as an example, the above explanation can also be applied to a continuous sheet casting machine using a twin belt method illustrated in Fig. 2, and the same effect can be produced. It is clear that the water-cooled box of a twin-belt continuous sheet casting machine is also included in the scope of the present invention.
