摘要： PROBLEM TO BE SOLVED: To obtain the subject oiling agent exhibiting a low viscosity and an excellent lubricating property, capable of reducing an adhesion amount and the generation of seizing, and useful for producing highly lustrous stainless steel plates by a high speed rolling method by compounding a specific base oil, a surfactant and an extreme-pressure agent. SOLUTION: This water-soluble cold rolling oil agent comprises (A) a base oil comprising a mineral oil, a synthetic water (e.g. having 15-30 carbon atoms) or a synthetic hydrocarbon oil and having a viscosity of /s, preferably 4-6 mm /s, at 40 deg.C, (B) a surfactant such as a nonionic surfactant (e.g. a sorbitan surfactant having an HLB of >=13) or an anionic surfactant, and (C) an extreme- pressure agent such as a sulfur-based extreme-pressure agent having a sulfur content of >=10 wt.% and a phosphorus-based extreme-pressure agent having a phosphorus content of >=5 wt.%. The oiling agent preferably contains the components B and C in amounts of 5-30 wt.% and 1-10 wt.%, respectively, based on the whole amount of the oiling agent.
