るものでおる。(Prior Art) Conventional methods for producing ingots from semi-molten metal slurry (hereinafter referred to as slurry) generally involve mechanically shearing dendrites that are formed in the solidification temperature range below the liquidus temperature of the metal. The product is manufactured from the slurry.
これを例えば第2図に基づき説明する。This will be explained with reference to FIG. 2, for example.

転子(8)が挿入されている。That is, there is a tundish (2) equipped with a heating element (1) for holding a metal melt field, and a tundish (2) with a melt 1 at the lower end.
A slurry forming chamber (3) equipped with a heating element (1) for maintaining the slurry (19) at a temperature suitable for slurry formation is provided, and below the slurry forming chamber (3), a water-cooled mold ( 5) is arranged, and the slurry forming chamber (
A rotor (8) whose outer periphery is provided with irregularities in the circumferential direction is inserted into the interior of the rotor (8) in order to mechanically shear the dendrites formed in the solidified region of the molten metal.
そして溶g(19)は図示せぬ保持炉より連続的にタン
デイツシュ(2)に移送され、その場面(20)高さが
常に一定となる様に図示せぬ制御手段によって制御され
ている。またタンデイツシュ(2)内の溶湯(19)の
温度は、鋳造金属の融点より5〜10℃以上高い温度に
保持されており、一方該スラリー形成室(3)内の温度
は鋳造金属の液相線温度より僅かに低く保持されている
ので、タンデイツシュ(2)からスラリー形成室(3)
に導入された溶1(19)は冷却されてデンドライトを
晶出し、回転子(8)の回転により直ちに剪断されて1
次固体粒子、すなわちセル(固相) (21)となる。The molten g (19) is continuously transferred from a holding furnace (not shown) to the tundish (2), and is controlled by a control means (not shown) so that the height of the scene (20) is always constant. Furthermore, the temperature of the molten metal (19) in the tundish (2) is maintained at a temperature 5 to 10°C higher than the melting point of the cast metal, while the temperature in the slurry forming chamber (3) is maintained at the liquid phase of the cast metal. Since the temperature is maintained slightly below the line temperature, the temperature is maintained slightly lower than the line temperature, so that the temperature is
The melt 1 (19) introduced into is cooled to crystallize dendrites, which are immediately sheared by the rotation of the rotor (8) to form
Next, it becomes a solid particle, that is, a cell (solid phase) (21).

It becomes solid and becomes an ingot (18) with a pinch roll (1
7) is continuously drawn out.
(発明が解決しようとする課題〕
ところが上記方法により得られる従来の鋳塊の品質は次
のような欠点を有するものであった。(Problems to be Solved by the Invention) However, the quality of conventional ingots obtained by the above method has the following drawbacks.
(1)結晶はスラリー中のセル(同相)と液相により新
たに晶出したデンドライトが混在する組織でおる。(1) The crystal has a structure in which cells in the slurry (in the same phase) and dendrites newly crystallized by the liquid phase are mixed.
(2)添加元素が偏析する。(2) Added elements segregate.
イ、鋳肌近傍に逆偏析層がある。B. There is a reverse segregation layer near the casting surface.
口、中心部の合金元素濃度が高くなる。The concentration of alloying elements in the mouth and center increases.
そしてこれら欠点は次に示すような原因によるものでお
る。These defects are due to the following causes.
即ち、スラリーを形成しようとする溶湯温度■において
剪断による固相率fsはp famの式と平衡状態図か
ら下記(1)式で求められる。That is, the solid phase fraction fs due to shearing at the molten metal temperature (2) at which a slurry is to be formed is determined by the following equation (1) from the equation of p fam and the equilibrium phase diagram.
TM:純金属の融点(°K)
TL:合金の液相線(°K)
K :分配係数
従って、固相率fsは、スラリーを形成しようとする溶
湯の温度Tで決定され、その温度が低いほど同相率fs
は高くなるが、一方次第にスラリーの流動性が劣化する
ために実際の溶湯温度は液相線温度近傍としている。こ
のため実際は液体を多く含む同相率の低いスラリーを使
用することとなり、スラリーの凝固潜熱が多く存在する
ことになる。よって凝固の際に充分な冷却速度を与える
事が出来ず、低速鋳造となる事、及び第2図に示すよう
にスラリーと完全固体(鋳塊)との境界線(以下ズンプ
と記す)(22)は中心部が極端に凹んだ形状となる事
等が原因となっている。TM: Melting point of pure metal (°K) TL: Liquidus line of alloy (°K) K: Partition coefficient Therefore, the solid phase fraction fs is determined by the temperature T of the molten metal in which the slurry is to be formed; The lower the in-phase rate fs
However, the fluidity of the slurry gradually deteriorates, so the actual molten metal temperature is set near the liquidus temperature. Therefore, in reality, a slurry containing a large amount of liquid and a low homophase ratio is used, and a large amount of latent heat of solidification is present in the slurry. Therefore, it is not possible to provide a sufficient cooling rate during solidification, resulting in low-speed casting, and as shown in Figure 2, the boundary line between slurry and completely solid (ingot) (hereinafter referred to as Zump) (22 ) is caused by the extremely concave shape of the center.
本発明はこれに鑑み種々検討した結果、これらの問題を
全て排除可能にした鋳塊の製造方法とその装置を開発し
たものである。In view of this, the present invention has been made as a result of various studies and has developed an ingot manufacturing method and apparatus that can eliminate all of these problems.

るのは有効である。That is, the method of the present invention maintains a molten metal in a solidification temperature range below the liquidus temperature of the metal, and further mechanically stirs the molten metal to produce an ingot from a semi-molten metal slurry. It is characterized by adding metal powder to the molten metal being stirred, and it is effective to supply a mixture of pressurized gas and metal powder to the molten metal being stirred.

内に放出することを特徴とするものである。In addition, the apparatus of the present invention includes a rotor having a stirring section at the tip inside the slurry forming chamber equipped with a heating device that maintains the molten metal in a solidification temperature range below the liquidus temperature of the metal, and rotates the rotor. In an apparatus for producing an ingot from semi-molten metal slurry by rotating its tip stirring part to mechanically stir molten metal, a passage is formed in the rotor,
A hole is provided in the tip stirring section to communicate the passage with the outside, and a mixture of metal powder and pressurized gas is supplied into the passage from the other end of the passage, and the mixture is stirred through the hole. It is characterized by being released into molten metal.

えて凝固させることが可能となる特徴を有する。[Function] The purpose of dispersing the metal powder into the molten metal in this way is to use the powder to crystallize the same phase, or to make the powder itself into a solid phase, which is caused by the shearing of the dendrites due to the rotation of the rotor. This is because a slurry with a high solid phase ratio can be formed, and the latent heat of solidification of the slurry can be significantly reduced compared to conventional methods, and the slurry can be solidified at a high cooling rate. have
