PURPOSE:A cold rolling oil for steel plates, obtained by adding a small amount of a water-soluble chelating agent and/or a specific water-soluble organic acid to an emulsion prepared by emulsifying an animal or vegetable oil in water, having improved roughness abrasion resistance of work rolls, and capable of preventing slip and chattering. CONSTITUTION:A cold rolling oil obtained by adding 0.01-1.0%, preferably 0.05-0.5% (A) water-soluble chelating agent, e.g. tetrasodium ethylenediaminetetraacetate, and/or (B) water-soluble organic carboxylic acid, e.g. a 6-10C fatty acid such as oxalic acid, to an emulsion prepared by emulsifying an animal or vegetable oil in water. Preferably, an extreme-pressure additive, etc. is if necessary added thereto. EFFECT:Productivity is improved, and formed iron compounds of the water-soluble organic acid are converted into a surface film, which prevents the seizure between work rolls and materials to be rolled. |
