冷却条件を維持するための方法が各種検討されている。2. Description of the Related Art In recent years, in producing a battery or a hydrogen storage alloy for hydrogen storage, in order to further improve the characteristics of the alloy, a quenching method such as a strip casting method or an atomizing method is used. Is being studied to produce an alloy having a uniform crystal morphology and no segregation in composition. In such a production method, since the purpose is to make the inside of the alloy have the same metallic structure, composition, and crystal grain size as much as possible, when cooling the molten alloy, the molten metal is cooled under controlled conditions. In particular, the throughput per batch to be melt-cast at a time is several hundred k
In production scales of up to g, the method of maintaining uniform cooling conditions is difficult because the time for cooling the molten metal becomes longer and it becomes difficult to maintain the cooling conditions due to the specifications of melting equipment and cooling equipment. Have been studied.

なくなっていた。However, the alloy cooled in a roll and formed into a thin strip or flake is 100 ° C. to 300 ° C. below the melting point of the alloy.
Since they are only cooled down to ℃, if they are received in a container such as a recovery case as they are, heat storage will occur inside the container, inviting the same state as when an inappropriate heat treatment was applied, and consequently microstructure segregation and As a result, the crystal lattice strain was increased. In particular, the amount of dissolution per batch is 100
At scales exceeding kg, the total volume of the ribbons and flakes formed is large, so the degree of heat storage differs in each part of the deposited ribbons and flakes, and as a result, the heat received by the alloy in each part The histories were different, causing the alloy properties to change. Since the obtained ribbon or flake has non-uniform properties, it is necessary to perform heat treatment for a long time at a high temperature, which is also used in the conventional casting method, to make the properties uniform, The advantages were reduced compared to the conventional method.

題があった。With respect to cooling the alloy formed on the ribbon or flake, such an alloy is stored and cooled separately in a container dedicated to cooling, or the inside of a cylindrical body whose outer peripheral portion is cooled is cooled. There has been proposed a method of slowly moving the camera. However, in the method of receiving in a container dedicated to cooling,
Since the inside of the container needs to be cooled uniformly, the size of the container is limited. For this reason, when the scale of the dissolving batch became large, the number of containers had to be increased. When the number of containers increases, handling tends to be complicated, and the air easily mixes into the container and the inside of the melting furnace particularly when the containers are switched. As a result, there is a problem that the alloy is oxidized in the course of cooling by the mixed air, thereby deteriorating the characteristics of the product alloy.

来たし、生産設備として採用することができなかった。In the method in which the outer peripheral portion is gently moved in the cooled cylindrical body, a part of the alloy is crushed when the alloy is moved, and fine powder may accumulate in various parts inside the device. For this reason, when trying to separately produce product alloys having different compositions, it is very difficult to clean the inside of the equipment, and it has not been possible to adopt it as a production facility.
