2. Description of the Related Art It is known that a large reduction in unsolidified portion (hereinafter referred to as unsolidified large reduction) has a remarkable effect in improving the central quality of a continuous cast piece having a rectangular cross section. As shown in FIG. 3, the unsolidified large pressure reduction for the rectangular section slab is performed by the drawing and straightening device 5 and the drawing and straightening device 5.
There is a case where a dedicated large pressure reduction device 7 is provided between the slab cutting device 6 and the large pressure reduction device. 1 is a ladle, 2 is a tundish, 3 is a mold, and 4 is a secondary cooling zone. By the way, round cast slabs having a circular cross section are only subjected to indirect means such as low-temperature casting, electromagnetic stirring, and light pressure reduction, and there has been no example of large pressure reduction.
The reason why this large reduction was not performed was that there was no large reduction method or apparatus for round slabs that did not generate internal cracks, and it was also necessary to obtain a slab outer shape as cast in a continuous casting machine with a substantially circular cross section. It is thought that it is aiming at. Then, only under light pressure, it was not possible to expect the concentrated molten steel to be squeezed out of the central part before solidification, and the effect of improving the segregation of the center was small.

[0003] As a conventional example relating to unsolidification reduction,
There is a technique described in Japanese Patent Publication No. 44-17366. In this conventional example, a slab having a liquid core still causing a core defect after a casting process is formed into a square or circular billet in a single pass by a molding process, and an initial cross section is formed. This is a technique for making the cross-sectional area difference based on the molding between billets larger than the cross-sectional area of the liquid core part to be displaced. The forming method can be understood from the description in the above-mentioned gazette that column 2, line 4, lines 18 to 19 indicate "both forming rolls ..." by rolling with two rolls. The target slab is an oblique polygon or a rhombus. However, the content of this prior art publication is fairly conceptual, and there is no concrete description of a measure for preventing internal cracks generated at the solidification interface inside the unsolidified rolling slab. In reality, it has been confirmed by the present inventors that the following problems occur when a large reduction is applied by two rolls.

[0004] That is, as shown in FIG.
When the roll is rolled down, assuming that the unsolidified portion is the shaded portion in FIG. 7A, as shown in FIG. 7B, the reduction area is larger than the shaded portion when the δ mm is reduced as shown in FIG. However, when a large pressure is applied by two rolls, biting occurs in the direction of the arrow as shown in FIG. When the rhombic slab is greatly reduced as shown in FIG. 5 (A), similar cracks occur in the X portion as shown in FIG. 5 (B). At this point, the unsolidified rolling method (BSR method:
That is why Bohler-Strang-Reduzier Verfahren) did not succeed.

[Action] In the inventions of claim 1 to make a cast piece having a circular cross section that can axially symmetric manner by homogeneously coagulated because firstly no corners. It has been found that the quality of the corners of the polygonal slab is different from that of the inner periphery, and this cannot be homogenized even if it is rolled in a later step. However, in the present invention since making no corners round cast piece, the center quality improvement effect by the subsequent rolling process becomes more uniform, and this poses the reason that obtained good slab quality.
When the round slab leaving the unsolidified portion is rolled down by a roll mill from four or more directions, a tensile stress is not generated in the slab cross-section in the radial direction and the tangential direction. no risk, and because only occurs compressive stress crimping of squeezing the central cavity of the concentrated molten steel of an unsolidified portion by a large reduction is effectively performed, thereby the center quality Ru is greatly improved. Large pressure reduction with roll mill
After this, the slab becomes a rectangular slab, but originally a round slab.
Therefore, the sectional structure is uniform, and in addition to this,
The quality has also been improved so that very good quality slabs are obtained. If the solidified cross-sectional structure of the slab is not uniform, it is generally difficult to homogenize it by rolling. Then, the inhomogeneity caused by the unavoidable corners is eliminated. Furthermore, since round cast slabs are also advantageous in terms of electromagnetic stirring and secondary cooling, cast slabs with good central quality can be manufactured. In the continuous casting facility according to the second aspect of the present invention, since the four-roll mill is installed between the secondary cooling zone and the slab cutting device, the round slab having unsolidified portions can be enlarged from four directions. Can be reduced. The area reduction rate is 36.3% or less.
The upper pressure is applied to finish it in a rectangular cross section.
Effectively squeeze concentrated steel. Ideal for The solid phase ratio at which center segregation is remarkably improved differs depending on the type of steel to be cast. Therefore, when the stand is fixed, the casting speed may be adjusted so that the four-roll mill falls within the region of the appropriate solid phase ratio. Further, when the four-roll mill is movable as in the third aspect of the present invention, it is possible to reduce the casting speed without any change in the solid phase ratio, so that the quality of the slab center can be made uniform. Can be improved.

Next, a continuous casting method using the continuous casting equipment will be described with reference to FIGS. The slab cast in the round cast slab casting mold 3 is drawn out in a circular cross section, and drawn out while being cooled in the secondary cooling zone 4. During this time, the slab solidifies from the outer periphery and an unsolidified portion remains on the inner periphery, but the unsolidified portion in the cross section of the slab gradually decreases from a large state. Then, a large pressure is applied by a four-roll mill 8 in a state where the unsolidified portion still remains. With this large reduction, the concentrated molten steel in the unsolidified portion is squeezed out, thereby improving center segregation and eliminating center porosity to improve center quality.

The large reduction of the round slab by the four-roll mill 8 enables rolling without generating a tensile stress in the cross section of the slab. For example, in FIG. 2, if FIG. 2A shows the cross section of the slab S before rolling, when the flat roll 11 is used as shown in FIG. 2B, the area reduction rate is 36.3%.
In the case where the caliber roll 12 is used as shown in FIG.

Since the solid fraction at which center segregation is remarkably improved differs depending on the type of steel to be cast, a four-roll mill stand 8 is used.

It should just be incorporated in.
When the four-roll mill 8 is movable along the pass line, by changing the installation position of the four-roll mill 8, a large pressure reduction can be performed in the state of the optimal solid phase ratio without changing the casting speed. .
