【発明の名称】粒子安定化発泡金属の成型スラブの製造方法と装置
Document Type and Number:
Japanese Patent JP3045773
Kind Code:
B2
Abstract:
A process and apparatus are described for manufacturing particle stabilized foamed metal slabs. A foam is first formed in a foaming chamber by heating a composite of a metal matrix and finely divided solid stabilizer particles above the solidus temperature of the metal matrix and discharging gas bubbles into the molten metal composite below the surface thereof to thereby form a stabilized liquid foam on the surface of the molten metal composite. The stabilized liquid foam is continuously drawn off the surface of the molten metal composite and is solidified into a shaped foam product while being continuously drawn off.
