Definitions

  • An extrusion die has a heat-resistant portion, a surface region of which, in contact with the metal block and with the product extruded therefrom, defines uniformly distributed fine pores, the porosity of which is from 10 to 50 percent.
  • the instant invention provides that the well-known methods for improving the heat resistance of this material may be applied, such as dispersion hardening and/or embedding of most finely distributed non-metallic parts such as oxides or nitrides. It is also possible, in accordance with the invention, to produce the die pores which are disposed at least Within the aforesaid surface region, by means of other methods such as spark erosion or electrolytically, or by other similar methods.
  • the material for the extrusion dies, or for the aforesaid die portions or at least the aforesaid surface regions may have the following well-known alloy ingredients for high heat resistance, in the proportions set out below by way of example in percentages by weight:
  • FIG. 1 is a vertical sectional view of a die including a die portion in accordance with an embodiment of the invention
  • FIG. 2 is a sectional view, similar to FIG. 1, but embodying a modification
  • FIG. 2 The modification of FIG. 2 is similar to the embodiment of FIG. 1, but the portion 1 has a conically outward flaring outlet 3.
