Provided is a rolling oil in which adhesion of a metal material to a rolling roll does not occur easily even under severe lubrication conditions, and the production of roll coating is small. The rolling oil has a kinematic viscosity at 40 ° C. of 75 mm 2 / s or more and 150 mm 2 / s or less, and is blended with the following A component and B component. It is 35% by mass or more based on the total amount of oil. Component A: mineral oil having a kinematic viscosity at 40 ° C. of 300 mm 2 / s or more, a viscosity index of 50 or less, and a density at 15 ° C. of 0.89 or more B component: a kinematic viscosity at 40 ° C. of 10 mm 2 / s or more, 40 mm 2 / S or less, end point of distillation is 600 ° C. or less, at least one of mineral oil and ester compound [selection figure] None |
