An aluminum foil is formed from an alloy of type AA1xxx, AA3xxx, and/or AA8xxx, which has a cold-solidified state and contains on its surface a rolling oil layer with a polyalkylene glycol or a compound containing a polyalkylene oxide structure. The aluminum foil has a thickness of 4 μm to 100 μm and can be easily coated with an electrode suspension for producing a battery film.

Aluminum foil with improved wettability

Described is a cooling lubricant for cold rolling aluminum, which includes a mineral oil-based or synthetic base oil and a polyalkylene glycol or a compound with a polyalkylene oxide structure. Further, the cooling lubricant is not water-soluble or miscible with water, and the cooling lubricant is substantially free of fatty acids and fatty alcohols.

Cooling lubricant for cold rolling aluminum

Disclosed is a method for the recovery of filtering agents and rolling oil from a mixture containing used rolling oil and filtering agents coated with used rolling oil in which the mixture containing rolling oil and filtering agents is subjected to vacuum distillation under agitation in a reactor equipped with an agitator and vapour precipitator. The vacuum during distillation is regulated with an inert gas flow, the rolling oil is condensed and collected, and a rolling oil which can be reused for rolling and a powder filtering agent which can be reused are obtained.

Processing of filtered rolling oil and filtering agents

The object of providing a method for conditioning a working roll with which the material properties of a working roll can be set in a process-reliable and uniform manner is achieved by a method in which a roll and at least one pressure tool are rotated relative to each other, in which pressure is applied locally to the roll by means of the at least one pressure tool, comprising at least one pressure element, via the at least one pressure element, and in which a deep rolling process is carried out.

Method and device for structurally conditioning a roll

The present invention relates to a method for reconditioning bearing lubricants that can be used in equipment for metal working, in which cooling lubricant that can be used in equipment for metal working is separated from the bearing lubricant. In addition the invention relates to a bearing lubricant for use in the method according to the invention.
