Abstract

The invention discloses a nickel base mould material for hot extrusion of nonferrous metal and a manufacturing method thereof. The mould material contains the following components in percentage by weight, with the total of mould material being 100%: 0.03-0.08 C, 15-20 Cr, 2-5 Co, 3-6 W, 9-12 Mo, 1-2 Al, 2-4 Ti, 10-15 Fe, 0.01-0.015 Mg, 0.02-0.06 Zr and the balance of Ni. The Ni in the mould material is used as a basal body, and the W and the Mo which both have higher content are added in the mould material, thereby the wearing resistance of the material is greatly improved and the service performance of the material is improved.

Description

technical field [0001] The invention relates to a mold material preparation technology, in particular to a nickel-based mold material for nonferrous metal hot extrusion and a heat treatment preparation process thereof. Background technique [0002] Hot extrusion is a process in which the billet is forced to pass through the opening of the forming die. It is used to produce materials that cannot be formed by cold extrusion. It is used in the production of long and straight non-ferrous metal products such as rods, solid and hollow profiles with equal cross-sections. , Pipe, wire and strip are widely used. Hot extrusion is to heat the non-ferrous metal to be extruded to the specified temperature of the process, and push it into the extrusion die barrel. Extruded to obtain hot extrusion products of different specifications. [0003] Extrusion die is a key component in the production of non-ferrous metal hot extrusion, its service life and quality will greatly affect the qualit...
