HOT-ROLLING OIL COMPOSITION AND METHOD FOR HOT-ROLLING FERRITIC STAINLESS STEEL

摘要

PROBLEM TO BE SOLVED: To solve the problem that in prior art, scale defects can not be sufficiently reduced in the case of high-corrosion resistance steel materials and materials requiring low-temperature rolling.;SOLUTION: A hot-rolling oil composition includes a base oil comprising at least one member selected from among a mineral oil, a fat and oil and a synthetic ester, and an additive comprising at least one member selected from polysulfides and sulfided fats and oils, and further includes 0.1-30 mass% solid sulfur particles of a particle diameter of 0.2-10 μm.;COPYRIGHT: (C)2010,JPO&INPIT
