Abstract
Capsule for pressed bodies for the extrusion of objects, especially tubes, bars or similarly profiled objects, longitudinally stretched, dense metallic, especially stainless steel or high-alloy nickel steels, especially heat-resistant steels for form changers, for example, alloy steels Nickel than that with high alloy with nickel and 2O chrome, with a thickness of 1 to 2 mm. and advantageously low in carbon, having a carbon content of less than 0.015%, preferably less than 0.004% and filling in the capsule, metal or metal powder or their mixtures of metal powders and/or metal alloys, ceramic powders, preferably consisting of spherical or predominantly spherical, which are pressed in a protective gas atmosphere, preferably argon from the desired starting material by spraying and in which the density of the powder in the capsule is increased by vibration preferably with 80 to 100 Hz to around 60 to 71% of the theoretical density and after closing the capsule, the density of the powder is increased, by pressing with a pressure of at least 4000 Bar, preferably from 4200 to 6000 Bar, especially 4500 to 5000 Bar, subsequent to so thin, less 80 to 93% of the density is characterized in that at least the outer shell of the capsule is provided with a directed bulge contrary to the contraction in the pressing and outwards, that this, dimensioned in such a way that by the contraction in essence it is eliminated again.
