FINE FILTRATION OF ROLLING MILL FLOOD COOLANT OILS

Abstract

THE ROLLING of bright metal sheet strip and foil requires that the highly finished rolls should be lubricated. Originally a drip feed was used, just sufficient to maintain an oil film, but as the output required from mills rolling at high speeds has increased there has been an almost universal adoption of flood cooling by means of a light mineral oil with additives. These additives are usually natural fatty substances like lanoline, vegetable or coconut oil or chemical additives in the form of complex higher alcohols. The additives are chosen largely according to the advice of oil suppliers and are usually compounded with the oil before purchase but occasionally may be blended to the preference of the mill manager as a result of his own experience. In many cases the exact mixture is regarded as a trade secret, a situation which may complicate the problems of filtration.
