The invention relates to a rolling oil for a stainless steel, which is prepared by the following raw materials by weight: 64.5-79.9% of
white oil, 5-15% of neopentyl
polyol ester, 5-10% of
pentaerythritol aliphatic ester, 2-5% of isooctyl
stearate or
butyl stearate, 0.5-1.2% of mixed-type high temperature antioxygen, 0.05-0.2% of
phenol-type antioxygen, 0.05-0.1% of
ethylenediaminetetraacetic acid (EDTA) dipotassium salt, 0.4-0.8% of antirust additive, 0.1-0.5% of
metal passivator and 2-3% of antiwear agent. The invention uses synthetic ester to replace chlorinated paraffin, which prevents environmental
pollution of chlorinated paraffin, meanwhile avoids using large quantity of water for cooling, saves massive
water source and also converts the
processing oil into recyclable oil, thereby prolonging the service life of the
processing oil greatly. The invention has the features of excellent
lubrication performance, cooling performance,
rust resistance, cleanness,
energy conservation andenvironmental friendliness. The waste liquid is less in volume and can be recycled. Therefore the rolling oil provided by the invention is the preferred
processing oil for finishing rolling of stainless steel to obtain high-gloss surface.
