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.
