PURPOSE:To obtain the subject cold-rolling oil having good slip resistance, seizing resistance and lubricity and giving a rolled steel plate having accurate thickness and excellent surface quality by compounding specific amounts of a phthalic acid ester, etc., and a specific sulfurized oil and adjusting the viscosity to a specific level. CONSTITUTION:The objective cold-rolling oil contains (A) >=25wt.% of an ester of phthalic acid and/or trimellitic acid and a 4-18C aliphatic alcohol and (B) 2-10wt.% of a sulfurized oil having a sulfur content of 20-35wt.% and produced by sulfurizing a mixture obtained by adding 10-35wt.% of a 8-18C olefin to oleyl oleate and has a viscosity adjusted to 5-25cst at 50 deg.C. |
