Water-soluble copper, copper alloys and non-ferrous metals intermediate cold and hot rolling composition

摘要

The present invention relates to a water soluble copper, copper alloys and non-ferrous metals intermediate cold and hot rolling composition comprising a base stock oil and, based on the total weight of the composition:-from 1 to 80% by weight of a combination of a monester of fatty acid with polyol and a tetraester of a fatty acid with pentaerythritol the weight monester:tetraester ratio of said combination ranging from 1:20 to 10:1; and-from 0.02 to 2% by weight of an azole derivative. The invention also relates to an oil-in-water emulsion, an intermediate cold rolling process, a hot rolling process and the use of the oil-in-water emulsion in an intermediate cold or hot rolling process.
