Patent number: 7281568Abstract: A method is described for producing a stratified composite material, with a melt of a layer material being cast progressively in a forward feed direction onto a strip-like metal carrier which is heated to a treatment temperature required for the bonding with the layer material and is cooled below the melting temperature after the casting via the metal carrier. In order to provide advantageous casting conditions it is proposed that the metal carrier is heated continuously with a temperature profile prior to the casting of the melt of the layer material in the forward feed direction, which temperature profile decreases towards lower temperatures from a maximum temperature below the treatment temperature in the region of a surface layer receiving the melt towards a core layer of the metal carrier, and that the metal carrier is heated in a surface layer by the melt to the treatment temperature upon casting of the melt which is overheated for this purpose.Type: GrantFiled: June 1, 2005Date of Patent: October 16, 2007Assignee: Miba Gleitlager GmbHInventors: Robert Mergen, Günther Kutzik
