Lubricating oil for press working and press working method of metal material using the same

[PROBLEMS] To provide an environment-friendly non-chlorine having good seizure resistance and lubricity, good odor and excellent quick-drying property even when press-working an electrogalvanized steel sheet with low workability and low coating weight. It is to provide a system lubricant. A lubricating oil for press-working an electrogalvanized steel sheet having a coating adhesion amount of less than 40 g / m 2 , and containing 4 to 7% by weight as a lubricating component in a base oil composed of paraffinic hydrocarbons. The adjustment oil comprises (a) a sulfur-based extreme pressure agent and (b) a calcium-based additive, and the sulfur content of the component (a) is 6 to 7 based on the total amount of the adjustment oil. The calcium content of the component (b) satisfies 0.5 to 1.0% by weight based on the total amount of the adjusted oil. [Selection figure] None
