<p>A method of recovering and regenerating a mold lubricant for hot forging, in which a recovered liquid flows into a reusable liquid supply tank (50) through a springed hose (46) after scale is removed from a recovered mold lubricant (recovered liquid) for hot forging. When it becomes necessary to operate a floating oil recovering device (54), an agitator (52) stops to make the recovered liquid stationary. After a predetermined period of time required for an oil to float has elapsed, the oil recovering device (54) is operated to separate and recover the oil floating on the recovered liquid surface. When an operation time set in an operation timer has elapsed, the oil recovering device (54) stops and the agitator (52) resumes its operation. Incidentally, the sum of a floating time of the oil and an operation time, that is, a stopping time of the agitator (52) is set within a range in which redispersion is not seriously affected by the amount of graphite particulates settled due to standstill of the recovered liquid. Accordingly, the graphite particulates are homogeneously redispersed by restarting the operation of the agitator (52), so that the oil can be recovered to enable the reuse of the mold lubricant with little deterioration of the performance of the mold lubricant.</p> |
