Abstract
Lubricant for use in hot forming of steel at high temperatures and especially in the production of seamless tubes in so-called multiple pipe mills, in which the lubricant must adhere water-resistant to the tool. This is achieved by a lubricant containing, besides a solid lubricant and a thickening agent, a binding agent from the series of the carboxylated styrene-butadiene latices.
