Problems solved by technology

However, if the roll diameter is small, the rigidity of the roll itself is low, and it is necessary to use a large-diameter intermediate roll or backup roll for reinforcement.

Abstract

A cold rolling oil composition comprising a base oil loaded with 0.5 to 30 mass% of a diester, the diester obtained from an aliphatic dicarboxylic acid of C12-C28 having a main skeleton constituted of a saturated or unsaturated hydrocarbon chain and an aliphatic alcohol of C1-C9, and 0.01 to 5.0 mass% of a phosphorus compound. The cold rolling oil composition is excellent in anti-heat-scratching properties (rolling properties) and can suppress gloss irregularity of rolled plate.

Description

technical field [0001] The present invention relates to a cold-rolling oil composition, and more specifically, to a cold-rolling oil capable of suppressing dark spots (poor luster) of rolled sheets of stainless steel materials while improving heat scratch resistance (rollability) combination. Background technique [0002] In the rolling of metal materials, a phenomenon called roll coating occurs in a part of the work rolls through which the rolled material passes during normal rolling, which is colored with a certain color tone. Since the work roll is often in direct contact with the rolled material, the roll coating has a great relationship with the rollability or the surface shape of the rolled product. [0003] When the metal material is rolled, the above-mentioned work rolls are thermally expanded due to frictional heat or processing heat, so the rolling pressure in the width direction of the sheet is not uniform, and roll coating spots are likely to occur. The coating...
