Abstract
The invention relates to a process for producing metal foams and to the metal bodies in foam form which are obtained in this way. The process for producing large-area integral metal foam by adding a blowing agent to a metal melt, is distinguished by the fact that the metal melt is introduced continuously into a roll nip and is brought into contact with a blowing agent which releases gases and is solid at room temperature, is formed in the roll stand and is fully foamed to form a large-area integral metal foam.
Claims11
A process for producing a large-area integral metal foam in an apparatus comprising a roll nip and a roll stand said process comprising preparing a metal melt, introducing the metal melt into the roll nip while contacting the metal melt in the roll nip with a blowing agent, forming the metal melt in the roll stand and foaming the metal melt to form a large-area integral metal foam, whereby said blowing agent is solid at room temperature.
