Abstract
Cooling rolls are spaced to have a gas of a size greater than thickness of metal thin bodies to be produced. A nozzle is arranged to eject molten metal onto a surface of the cooling roll. The first cooling roll quenches molten metal ejected from the nozzle into metal thin bodies. On the next cooling roll, the produced metal thin bodies are hit into flakes and excessive molten metal is made into metal thin bodies. Thus, freedom of supplying the molten metal flakes can be efficiently produced.
Claims12
A metal-flake manufacturing apparatus comprising, a first cooling roll, a nozzle is arranged to eject molten metal on a surface of the first cooling roll not tangentially but in a direction of collision with the latter, said first cooling roll adapted to quench the molten metal from the nozzle through collision into metal thin bodies and fly the produced metal thin bodies, and at least a second cooling roll on which the produced flown metal thin bodies are hit into flakes, said second cooling roll also serving for solidification of the molten metal not solidified by the first cooling roll, said cooling rolls being spaced apart by a gap of a size greater than thickness of metal thin bodies.
