溶製するための装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention involves adding solid particles having a composition different from that of the base metal, that is, third phase solid particles, to a solid-liquid phase coexisting base metal containing non-dendritic primary crystals. The present invention relates to an apparatus for producing a molten composite metal containing primary crystals and third phase solid particles.

れる金属材料の強度が比較的低くなる等の欠点が
ある。 Conventionally, methods for obtaining such composite metal materials include a method of adding solid particles to a base metal when it is in a molten state, and a method of sintering a mixture of base metal powder and solid particles. However, when simply adding solid particles to molten metal using the former method, only a very small amount of solid particles (generally about 3% by weight) can be added, because the solid particles are wetted by the metal. This is because solid particles either float on the surface of the molten metal or settle to the bottom. The latter method using powder metallurgy makes it possible to obtain a composite metal material in which solid particles are dispersed in a relatively high concentration within the base metal, but it not only has high manufacturing costs and poor processability. However, there are disadvantages such as relatively low strength of the metal material obtained due to porosity and other reasons.

Can be used. Stirring blade 3
If 1 is screw type, stopper 29
When the screw-type stirring blade is rotated in the closed state, hot water is sent downward, increasing the pressure of the hot water at the bottom end of the stirring tank, and as a result, the stirring blade is pushed upward, which causes the stopper 29 to rise. In order to prevent such an undesirable rise of the stirring blade, it is preferable to provide a suitable upward movement prevention mechanism in the upper part of the bearing.
