  • Metal rolling oil composition
    Patent number: 4693839
    Abstract: Disclosed herein is novel metal rolling oil compositions comprising lubricant oil components and specific type of water-soluble cationic or amphoteric polymer compounds, which are selected from the group consisting of polymer compounds having at least one recurring unit and having an average molecular weight of from 1,000 to 10,000,000.The thus obtained metal rolling oil composition gives a stable size distribution of relatively large sizes under agitating conditions of high shearing force and is useful as a rolling oil having a high lubricating and rolling performance with a reduced timewise change.
