Abstract: A method for lubricating the container and/or the mandrel of an extrusion press in the hot extrusion into bars or tubes of metals which are hot deformed at temperature above 500 DEG C. comprises incorporating a glass or a glass-like material in the form of a finely divided powder as a suspension into a grease and just before each extrusion evenly spreading the resultant mixture in a thin layer on the lateral surface of the extrusion container and/or mandrel. The grease may be of animal, vegetable, mineral or silicone origin and may be thickened by bentonite; it may also contain colloidal graphite. The composition of a suitable glass is B2O3 30%, SiO2 40%, Na2O 15%, CaO 10%, MgO 5%.ALSO:A lubricant for the container and/or the mandrel of an extrusion press for the extrusion of metals comprises a glass or a glass-like material in the form of a finely divided powder incorporated as a suspension into a grease.
