ABSTRACT:
Oil-type, deep drawing lubricants for use primarily on ferrous sheet metal surfaces and the like may consist essentially of a dispersion of from about 2 to 20 parts by weight of a high viscosity liquid polar lubricant dispersed as a discontinuous phase in an anhydrous, hydrocarbon, liquid vehicle of relatively low viscosity with the aid of at least one emulsifying agent. The lubricants preferably contain at least one corrosion-inhibiting agent and at least one agent for facilitating removal of the lubricant composition from the surface of a fabricated workpiece. The lubricants may be applied to a workpiece at the steel mill or in a blanking line by conventional liquid lubricant application procedures as thin films in which the dispersed phase quickly splits from the continuous phase and forms an ultra-thin, adherent film overlaid by a thin film of the material of the continuous phase.
