Abstract

An oil in water emulsion, which is used as a lubricant and coolant in the rolling of metal, has added to it a chelating agent which brings the titratable hardness of the emulsion, calculated as CaCO3, to from 5 to about 40 p.p.m., in order to increase the working life of the emulsion. The rolled metal can be Cu, Al or steel and the chelating agent ethylene diamine tetraacetic acid (EDTA), nitrilotriacetic acid, or one of many compounds listed. In an example, an emulsion of 94% water and 6% oil was used for rolling steel in a continuous mill, EDTA being added as a chelating agent. The steel left the fifth stand of the mill at 3500 feet/min. at a temperature of 325 F., 3000 gals./min. of emulsion being used at each stand.
