Composition for protection from scale and as lubricant for hot processing metals

A high-temperature lubricant for the hot processing of metals comprising a mixture of fine-powder materials. To provide a high-temperature lubricant having good trickle and flow characteristics for dissolving scale on heated metal surfaces, which applied in powder form permits good coverage of the metal surface and which even after prolonged storage under production conditions still has good trickle and flow characteristics without severe lump formation and which avoids the use of graphite, in accordance with the invention it is proposed that the mixture includes at least the following constituents (a) a secondary and/or tertiary calcium phosphate compound, (b) a fatty acid or a fatty acid salt, (c) boric acid, a boric acid salt (borate) and/or a mineral containing boric acid salt (borate), and (d) condensed alkali metal phosphates, and wherein the constituents of the mixture have a mean grain size of &#x2266;150 &#x3bc;m and the lubricant does not contain any addition of graphite.

Graphite-free high-temperature lubricant

The present invention concerns a high-temperature lubricant for the hot shaping of high-grade and carbon steels, which has a content of graphite, organic blowing agent and inorganic separation agent, and the use thereof. In order to provide a high-temperature lubricant which can be used for a wide range of steel qualities for different wall thicknesses to be rolled and stretching effects and which is moreover stable in respect of temperature, provides constant rolling results upon a change in the wall thickness and/or the quality of steel and does not lead to unwanted cementation of the rolled material,za the high-temperature lubricant according to the invention contains at least the following constituents in percent by weight with respect to the solids content:
