plastic metal working, namely rolling, drawing and stamping. SUBSTANCE: self-emulsifying oil comprises, wt %: fatty acids, 1-10; natural or synthetic fat, 1-50; emulsifier, 0.2-6.0; product of reaction of fatty acids with aliphatic amines and absorbing coal oil, 0.02-5.0; and mineral oil, the balance. EFFECT: fewer mechanical defects when cold rolled by 1.6-1.9 times, corrosion resistance increased by 3-6 times, improved surface finish by 2.5-4.6 times. 3 ex, 2 tbl |
