Abstract
A reducing hot rolling oil for copper and copper alloys comprising 1000 parts by weight of water, 6 - 200 parts by weight of at least one member selected from the group consisting of carboxylic acid type, sulfate type and phosphate type anionic surface active agents, and 0.8 - 200 parts by weight of at least one hydroxyl group-containing compound selected from the group consisting of alcohols, alkylene glycols and glycol ethers. The rolling oil can provide copper and copper alloys with lubricity, oxide film removing ability and oxide film formation preventing ability by spraying between a rolling mill and the metal to be rolled on the hot rolling of copper and copper alloys. The present invention relates to a rolling oil. More particularly, the invention pertains to a rolling oil which can provide copper and copper alloys with lubricity, oxide film removing ability and oxide film formation preventing ability by spraying between a rolling mill and the metal to be rolled on the hot rolling of copper and copper alloys. Hot rolling oils for copper and copper alloys which have heretofore been used consist mainly of a mineral oil emulsified with an anionic or nonionic surface active agen…
