In carrying out the thixocasting method, the casting material is subjected to a heat treatment to prepare a semi-molten casting material in which a solid phase and a liquid phase coexist, and then the semi-molten casting material is transferred to a pressure casting machine. ,
Thereafter, a method of filling the cavity of the mold with the semi-molten casting material under pressure is performed. In this case, for example,
As a casting material, a material that has a substantially short columnar shape is used, which is installed in a high-frequency coil in an upright state during the heat treatment, and the outer periphery of the semi-molten casting material is gripped by a clamp member during transfer. Is done.

が要求される。[0003] Therefore, a cast material for thixocasting must exhibit uniform softening properties over the entire material at a relatively low temperature, that is, have good rheological properties.
And it is required that the shape maintenance property in the semi-molten state is excellent.

2 is set to, for example, r 2 ≧ r 1 +20 mm. This means that if r 2 <r 1 +20 mm, the upper part of the water-cooled mold,
Because the temperature difference between the lower part of the spout and the lower part of the spout is small, the molten metal does not solidify even if it comes into contact with the water-cooled mold. This is because it flows backward to the molten metal inlet side and casting cannot be performed.

In contrast to the above, the temperature difference between the upper part of the water-cooled mold and the lower part of the spout adjacent to the water-cooled mold becomes large, so that the molten metal is rapidly cooled by the water-cooled mold, and dendrites are easily generated on the outer peripheral part of the continuous casting material. . Due to the presence of the dendrite, such a material has a good shape maintaining property in a semi-molten state, but has a problem that the softening property of the outer peripheral portion is deteriorated and the rheological property is poor.

A spout having an upward molten metal receiving port and a downward molten metal outlet, a cylindrical water-cooled mold disposed immediately below the spout to cool the molten metal from the molten metal outlet, and an electromagnetic stirring force applied to the molten metal in the spout. In the stirring continuous casting apparatus provided with a stirrer to be applied, the stirrer, in the spout, an upper region for moving the molten metal in a substantially radial direction,
It has a function of forming a lower region that rotates the molten metal in the circumferential direction, and moves substantially in the radial direction to shift the molten metal that has collided with the upper region forming portion of the inner surface of the spout toward the lower region. There is provided a stirring continuous casting apparatus in which the upper region forming portion has a tapered shape whose inner diameter gradually increases from an upper peripheral edge to a lower peripheral edge thereof.

い。In the upper region, a large number of high melting point crystallized products are formed. A large number of the high-melting-point crystals in the molten metal that have migrated from the upper region to the lower region are spheroidized by the stirring action rotating in the circumferential direction in the lower region, and are largely moved to the outer peripheral side by centrifugal force. . Thereafter, the molten metal is cooled by a water-cooled mold. During this time, the high-melting-point crystal transfer from the upper region to the lower region is continuously performed,
No backflow of refractory crystals from the lower region to the upper region occurs.

Show. Therefore, the continuous cast material has good rheological properties. In addition, since many high melting point crystallized substances are present on the outer peripheral portion, the continuous casting material exhibits excellent shape retention in a semi-molten state due to the shape preserving action of the high melting point crystallized substances.

The liquid was heated to a semi-molten state with a phase ratio of 50%, and the dripping rate of the liquid phase at that time was determined. The result shown in FIG. 11 was obtained. Examples 1 to 4 all have good shape retention. This is due to the shape-preserving action of the high melting point crystallized substance c in Examples 1 and 2, whereas it is due to the dendrite-preserving action in Examples 3 and 4.
