Definitions

  • the metallic capsules which are filled with the steel powder, can be evacuated before closing and / or with a gas, in particular an inert gas, e.g. Argo fill.
  • a gas in particular an inert gas, e.g. Argo fill.
  • lid 10 and bottom 20 can be omitted.
  • the insert according to FIG. 3 can be used in an analogous manner
  • the outer casing 102 in the area indicated at 150 essentially has a constant outer diameter. It has proven to be particularly advantageous to connect to the cylindrical sections 156, 166 towards the center of the capsule a region 157 or 167 with an outwardly concave cross-sectional profile and an intermediate region 158 or 168 in the shape of a truncated cone and this region 159, 169 to follow, which has an outwardly convex cross-sectional profile and merges into the cylindrical, axially parallel central region 150.
