Field of the Invention The present invention relates to a continuous casting method for ingots of aluminum (including aluminum alloys, the same applies hereinafter), and more particularly to a continuous casting method for ingots of aluminum capable of achieving further cooling strengthening.

Description of the Related Art Continuous casting of an aluminum ingot such as an aluminum slab (rectangular cross section) and an aluminum billet (circular cross section) is carried out from the upper part of a mold 1 opened up and down as shown in FIG. Is supplied to the mold through a float 3 for controlling the height of the molten metal surface, the molten aluminum 4 is supplied, the solidified shell is formed by the primary cooling in the mold 1, and the surface is directly cooled below the mold 1. Water 5 is supplied to perform secondary cooling, and the solidified ingot 6 is pulled out from the lower portion of the mold 1.

As shown in FIGS. 3 (a) and 3 (b), usually, the form of the water film flow 8 flowing out from the slit 7 at the bottom of the mold and the form of the jet flow 10 flowing out from the hole-shaped discharge port 9 However, for strengthening cooling, increase the amount of cooling water,
When the slit width or the hole diameter is reduced to increase the flow velocity, or when the collision angle of the cooling water with respect to the surface of the ingot is increased, as shown in FIG. After colliding with the ingot surface 11, a scattering flow 12 of the cooling water is generated by bouncing back on the surface 11.

生産性を低下させるという難点がある。As a result, the amount of cooling water that contributes to the cooling of the ingot is significantly reduced on the surface of the ingot below the collision point of the cooling water 5, so that the quality of the ingot is improved due to the coarsening of the surface structure and internal structure of the ingot. Deterioration and, if significant, remelting of the ingot also cause problems of molten metal leakage. When the ingot is large, the casting speed cannot be sufficiently increased due to insufficient cooling,
It has the drawback of reducing productivity.

A casting method using a dual jet (Dual-Jet) mold in which two kinds of cooling water at different angles are discharged as a jet flow from the mold has also been proposed (Table 1-5006).

The second jet stream 14 that hits the surface of the ingot at (45 °) and flows out from the hole-shaped discharge port also provided in the mold has a collision angle of 22 deg. (22 °) hits the surface of the ingot, and the outlets for outflowing the first jet stream 13 and the outlets for outflowing the second jet stream 14 are provided alternately, and the casting occurs at a high cooling water amount and a high collision angle. It is intended to prevent the scattering (bounce) of cooling water on the surface of the lump by alternately arranging the first jet and the second jet.

になり、鋳塊の強冷却が可能となる。That is, the first jet stream 13 collides with the surface of the ingot, then flows in the horizontal direction, and further merges with the adjacent jet stream and the intermediate portion of the jet stream. These jet streams have high velocity energy and are separated from the surface of the ingot (cast surface) and bounce off. However, since the second jet stream is flowing out between the first jet streams, the scattered stream 15 becomes the second stream. It is absorbed by the jet stream 14 and once again participates in the cooling on the casting surface, which enables strong cooling of the ingot.

流により安定して吸収されないことも多い。However, in this dual-jet mold system, the outlets for outflowing the first jet stream 13 and the outlets for outflowing the second jet stream 14 are provided alternately, and between the collision points of the first jet stream 13. Since the collision point of the second jet stream 14 exists in the lower center part of the first jet stream 13 when the scattering direction of the first jet stream 13 from the ingot surface is not within the water flow range of the second jet stream 14, the scattered first jet stream 14 There is a problem that the scattered flow 15 of the flow 13 cannot be absorbed. If the surface of the slab with a rectangular cross section is highly uneven, or if the surface has a curved surface, such as a billet with a circular cross section or an ingot with an irregular cross section, the scattering direction of the first jet flow becomes unstable and Often, the jet flow does not necessarily scatter in the water flow range, and the scattered flow of the first jet flow is often not stably absorbed by the second jet flow.
