Patent ID: 7959852

Claim:
A metal foam manufacturing device for manufacturing a metal foam usable with a mold for allowing the metal foam to solidify therein, the device comprising: a nozzle arrangement of the metal foam manufacturing device structured and arranged to form bubbles which abut one another and form interstructures, the nozzle arrangement comprising at least two feed pipes for introducing gas into a foamable melt and spaced to form the bubbles which abut one another and form the interstructures; a pressure chamber of the metal foam manufacturing device arranged under a nozzle assembly of a metallurgical vessel of the metal foam manufacturing device; the at least two feed pipes being arranged next to one another and projecting upwards from the nozzle assembly and into the foamable melt; and the mold receiving therein the metal foam formed from the foamable melt, whereby the metal foam is allowed solidify in the mold, wherein the gas is injected into the foamable melt through the at least two feed pipes and from the pressure chamber.
