Lubricants for the rolling and drawing of metals
A survey is given over lubricants for rolling and drawing of metals. Emulsions, suspensions, natural fats and oils and synthetic lubricants are presented. Fluid mechanics Reynolds equations are used for the calculation of the lubricant layer in the entering section of the metals deformation zone. Colloide chemistry is used for the analysis of surface active additions on lubricant properties, lubricant layer thickness and the wetting angle. Lubricants for hot rolling based on suspensions and glass are presented also. Special attention is given to the removing of lubricant from the surface after processing, to measures for the protection of workers and to ecological problems of used lubricants.
