Description of the Related Art Attention has been paid to a method for producing a slab having a thickness of several mm, which is directly close to a product, from a molten metal such as molten steel. In the case of the present continuous casting method, hot rolling is not required, and final rolling is small, so that the process and equipment can be simplified. FIG. 4 is a schematic explanatory diagram of a twin-drum type. In this method, a pair of cooling drums 1a and 1b rotating in opposite directions are arranged horizontally,
A pool 3 formed by the cooling drums 1a and 1b and the side dams 2a and 2b is formed. The molten metal is poured into the pool 3 through a container such as a tundish, and the molten metal 4 in the pool 3 is cooled by the cooling drums 1a, 1
Cooled and solidified at the portion in contact with b to form a solidified shell.

Here, reference numeral 15 denotes an end surface of the cooling drum, and reference numeral 16 denotes a sliding surface. Further, Japanese Patent Application Laid-Open No. H5-222054
In Japanese Patent Publication No. 6 (1999), the sealing property is degraded because the metal is stretched, but in order to prevent this, the side dam is vibrated along the cooling drum end face so as to rotate in the direction perpendicular to the drum axis direction. A method is disclosed for causing this to occur.

It is not a sufficient measure against the coming bullion, but a problem. As described above, it is desired to develop a technology that can further extend the life of the side weir by taking measures against overhang of the metal in twin-drum continuous casting.

In other words, a relatively soft metal with solid and liquid that has just started to coagulate on the side weir is pressed in the gap between the drums, and is pulled and rolled so as to continuously melt and mix in the vertical direction of the drum. The continuous outflow suppresses the intrusion of the bullion and prevents the bullion from sticking to the side weir.

シール性を破壊するにいたる。FIGS. 1 (a) to 1 (c) show the mechanism of metal adhesion observed by the present inventors through observation between the drum and the side weir. In these figures, FIG. 1 (a) shows a situation in which the massy molten steel 8 adheres to the side weir surface, and the massy molten steel in the massy zone 8 comes to adhere to the side weir. FIG. 1B shows a situation in which the adhered metal is entangled near the kissing point. In this figure, as the casting progresses, the center of the slab is drawn in 11, so that the upper slab starts to move 10 downward. Furthermore, the solidified material at the lower part of the retracted 11 has considerable solid strength, and the entrained 12 opens the gap of the drum, leading to a partial increase in the thickness of the plate.
At this time, a gap is also formed between the side weir and the drum, and the molten metal is inserted. As a result, it becomes a jug and destroys the sealing performance of the side weir.

対して不利となっていた。In order to prevent the adhesion of the bullion as described above, it is necessary to prevent the solidification of the bullion which has been initially adhered while continuously applying the action of quickly sending the bullion downward. is there. Conventional vibration caused by rotation of the side weir in the drum side direction has a large effect of moving the base metal in a direction perpendicular to the casting direction, and the component in the casting direction, that is, the moving direction component of the molten metal, has been small. For this reason, it is difficult for the metal to flow out in the initial stage, and the metal has accumulated strength and is disadvantageous against the occurrence of a jug in which the contact between the drum end surface and the side weir is insulated.

範囲に規定する。[0013] The present invention improves the movement of the side weir and imparts downward vibration in the casting direction to promote the downward movement, thereby reducing the massy zone as much as possible and reducing the distance between the drums. It promotes the sending of bullion. If the maximum acceleration of the vibration in the vertical direction is less than 3.9 m / s 2 , the effect of the downward feeding is insufficient and it is not possible to prevent the adhesion of the metal to the side weir. The frequency of the vertical vibration is 5 to 100 Hz, and the amplitude is 0.5 to 1.
If the distance is outside the range of 0 mm, solidification of the metal in the massy zone starts and the downward movement is not sufficient, so that the range is specified.

In the range where the condition of the vertical vibration does not satisfy the following relational expression, since the initially started metal is not pulled in by the rotation of the drum, the growth of the metal occurs, so that the preferable range is defined in this range. .

For comparison, a case where a conventional vibration was applied was tested. FIG. 2 shows an example of the vibration device of the present embodiment. FIG. 3 is a sectional view taken along line AA of FIG.

It can be seen that the results are excellent.
