摘要:
Disclosed is a method for the recovery of filtering agents and rolling oil from a mixture containing used rolling oil and filtering agents coated with used rolling oil in which the mixture containing rolling oil and filtering agents is subjected to vacuum distillation under agitation in a reactor equipped with an agitator and vapour precipitator. The vacuum during distillation is regulated with an inert gas flow, the rolling oil is condensed and collected, and a rolling oil which can be reused for rolling and a powder filtering agent which can be reused are obtained.
