Twin rolls 1-1 and 1-2 rotating in the direction of arrow 8 and side dam 1
It is poured into the basin 2 formed in 7. The molten metal is cooled by twin rolls to form solidified shells 3-1 and 3-2. The solidified shells 3-1 and 3-2 are integrated to form a strip-shaped metal casting 6.
Is taken out from the minimum gap 4 of the twin roll.
The solidified shells 3-1 and 3-2 are integrated at the minimum gap 4.

This is an example in which 7 is integrated before reaching the minimum gap 4. Thickness when integrated by 7, integrated into the thickness of the large t 2 mm than the minimum gap t 1 mm twin roll but, thickness t 2 m
It is not easy to pass the integral solidified part of m through the minimum gap of the twin roll of t 1 mm narrower than t 2 mm. As described above, the solidified shell is integrated at the minimum gap 4. Therefore, immediately before the minimum gap 4, the central portion of the slab thickness is in a molten state. Therefore, the micro-segregation in the liquid state is scattered in the slab 6 immediately after coming out of the minimum gap 4, and the temperature is extremely high. This makes them extremely vulnerable.

破断し易い。[0004] The strip-shaped metal slab removed from the twin rolls is wound into a coil. FIG.
It is explanatory drawing of conveyance winding of the slab described in 8452.
That is, the strip-shaped metal slab 6 taken out from the twin rolls 1 is tensioned by the deflector rolls 9 and 9 'and the tension roll 10 and wound up by the winding reel 11 to form a coil. When the strip-shaped metal slab 6 is wound up in a tight coil shape by this method, the strip-shaped metal slab 6 below the twin roll 1 is pulled with a strong force in the direction of the arrow. However, as described above, the strip-shaped metal slab 6 is fragile and thus easily breaks immediately below the minimum gap 4 between the twin rolls.

The coiling reaction force is large, making it difficult to wind up a tight coil even if tension is applied.

ましい。[0006] Since the strip-shaped metal slab has a casting structure having thermal stress during cooling, it is fragile unlike a rolled thin plate, and when it is pulled and conveyed, it is easily broken during the conveying process. FIG.
For example, when the strip-shaped metal slab 6 is broken between 9 and 11, the casting is stopped. It is preferable that the strip-shaped metal slab can be continuously wound up even after the strip-shaped metal slab 6 is broken in the middle of the transporting step, because the casting can be continuously performed.

For example, by synchronizing the running speed with the peripheral speed of the twin roll 1-1 (1-2), excessive tension is generated in the strip-shaped metal slab 6 immediately below the twin roll and the strip-shaped metal slab 6 being conveyed. Nothing. In addition, even if the winding reaction force of the strip metal casting 6 is large in FIG. 1 (B), since the supporting strip 13 tightens the strip-shaped metal casting 6 from the outside in the direction of arrow 15 and winds it, a tight coil is required. Can be formed. Further, according to the method of FIG. 1 (A), even if the strip-shaped metal slab 6 breaks in the middle of the transporting step, both the front part and the rear part of the break are placed on the support strip 13 and run and wound. Therefore, casting using the twin rolls 1-1 and 1-2 is not stopped. In the present invention, the support strip 13
Although there is no particular limitation on the type of, a mild steel strip or a stainless steel strip can be used.

When the strip-shaped metal slab 6 coming out of the twin rolls is supported by the slide guide 16 and is moved on the slide guide 16 obliquely downward, there is an effect of preventing the strip-shaped metal slab 6 from breaking. And filed a patent application in Japanese Patent Application No. 2-101573. FIG. 1C shows a transport winding method of the present invention when the slide guide 16 is used. In this case, the support strip 13
It is stretched between the rewind reel 12 and the take-up reel 11 via a turning roll 19. Naozu 1 method (C) has the same effect as in FIG. 1 (A), Ru apparent der from the description of FIG. 1 (A).

かかる張力は更に軽減する。For example, when manufacturing a strip of brittle metal material, if the distance between the twin rolls and the running path of the supporting strip is long,
The strip-shaped metal slab 6 hangs long below the twin rolls.
Of the strip-shaped metal slab 6 immediately below the minimum gap 4
Breaks. To prevent this rupture of the strip metal slab,
It is preferable to support the strip-shaped metal slab 6 directly below the twin rolls. In the continuous casting method shown in FIG. 2, the support strip 13 travels immediately below the twin rolls 1-1 and 1-2, and the strip-shaped metal slab 6 is placed on the support strip 13 with a short hanging distance. The placed strip-shaped metal slab 6 travels together with the support strip 13 to reach the take-up reel 11. In the take-up reel, the take-up reel 11 winds the strip-shaped metal casting 6 inside the support strip 13 and winds it together with the support strip, as described in FIG. 1B.
According to the method of FIG. 2, the tension applied to the strip-shaped metal slab immediately below the twin rolls is further reduced.

Even if the strip-shaped metal slab is hard and the winding reaction force is large, it can be wound into a tight coil. Further, even if the strip-shaped metal slab breaks in the middle of the transporting step, it can be continuously wound up, so that casting is not interrupted.
