Abstract

The invention relates to a cold rolling oil composition and use thereof, which is mainly used for solving the problems of heavy oil mist in a workshop after rolling as well as poor surface cleanness and poor annealing cleanness after rolling in the prior art. The cold rolling oil composition comprises the following components in parts by weight: a) 1-20 parts of aromatic acid diester, b) 1-25 parts of fatty acid monoester, c) 0.01-5 parts of a fog resistant agent and d) 50-97.99 parts of base oil; and the structural formula of the aromatic acid diester is shown in the specification, wherein R1 and R2 are chosen from alkyl groups with 3-8 carbon atoms. By means of the technical scheme, the problems are better solved; and the cold rolling oil composition can be applied to industrial production of stainless steel thin plates with 2B and BA high-precision grades.

Description

technical field [0001] The invention relates to a cold rolling oil composition and its application. Background technique [0002] Stainless steel is based on ordinary carbon steel, adding some alloying elements, such as chromium, nickel, molybdenum, titanium, niobium, etc., so that it has good chemical stability in air, water, and steam, and it is in many An alloy steel that has sufficient stability in aqueous solutions of acids, alkalis, and salts, and can still maintain its corrosion-resistant advantages even in high-temperature or low-temperature environments. Usually, people call alloy steel with a chromium content of more than 12 parts or a nickel content of more than 8 parts as stainless steel. [0003] Stainless steel sheet rolling is a processing method that rotates the roll under certain conditions to give pressure to the rolled piece to cause plastic deformation of the rolled piece. When the rolled piece is under pressure, the cross section decreases, the shape c...
