The invention discloses a rolling oil composition for a double frame reversible
rolling mill. The rolling oil composition comprises, by weight, 70-95% of a
polyol ester oiliness agent, 0-5% of a
polyphosphate extreme pressure antiwear agent, 0.1-10% of a
thioether extreme pressure antiwear agent, 0.1-5% of a
metal deactivator, 0.1-3% of a free radical inhibitor, 0.1-15% of a
fatty alcohol polyether surfactant, and 0.1-20% of a polysorbitol
nonionic surfactant. The rolling oil composition, which specially aims at specific technological conditions of the double frame reversible
rolling mill, such as characteristics of large
reduction rate, much very thin plate production and the like, has good fluid
lubrication,
boundary lubrication and extreme pressure
lubrication performances, has a wide mixed
lubrication area window, and provides excellent lubrication performances during
low speed rolling and high speed rolling, is suitable for rolling of high strength steels and
large deflection requirements, and simultaneously has a good cleaning property.
