Title:
APPARATUS AND METHOD OF MANUFACTURING FOAMY METAL
Document Type and Number:
Japanese Patent JP2003112253
Kind Code:
A
Abstract:
To provide an apparatus which is capable of putting gas into molten metal in the form of small pores or air bubbles having nearly the same volume and having adjustable sizes and a method of forming the desired foamy metal.
At least one gas feed pipe 1 projects and intrudes into the molten metal S and has a gas outlet section 2 having an area of 0.006 to 0.2 mm2 and a pipe end face 3 smaller than 4.0 mm2 at the intruding end. The uniformity of the diameters or sizes of the respective separate bubbles exists and the sizes of the air bubbles can be controlled by adjustment of the inflow parameter of the gas.
