Abstract (en)
An effective and simple controlling process for an aqueous lubricant of one process type used for cold forging of metallic material are explained. The process is carried out on an aqueous lubricant of one process type containing at least one water soluble inorganic salt. In order to obtain a preferred weight of the lubricative coating layer by applying this aqueous lubricant, the electric conductivity of the aqueous lubricant are measured and controlled in a preferred level by supplementing a constituent to the aqueous lubricant. <IMAGE>
