Abstract

The present invention relates to a hot extrusion method of alloy pipe material and its extrusion die arrangement. It includes an extrusion chamber, said extrusion chamber is placed in the extrusion chamber seat and is fixed on the base plate by means of pressure plate, the concave die is placed in the lower end of extrusion chamber and is fixed in the recessed groove on the base plate, the base plate is fixed on the base seat of extruder by means of bolt, the extrusion ram is set in the glass pad, extrusion billet material, graphite pad and extrusion pad, and is fixed on the extrusion shaft, and said extrusion shaft is fixed under the extrusion head of extruder by means of fixing seat. Said extrusion process includes the following steps: (1) preheating die arrangement; (2) applying lubricating agent; (3) heating billet material; (4) extrusion forming; (5) annealing; and (6) cleaning extruded pipe billet.

Description

technical field [0001] The invention belongs to the pipe hot extrusion technology, in particular to an alloy pipe hot extrusion method and an extrusion die. Background technique [0002] Superalloy materials have the advantages of good oxidation resistance, corrosion resistance and compression resistance at high temperatures, especially nickel-based superalloy pipes, which can be used at temperatures above 700°C and are widely used in aviation, aerospace vehicles, power generation, rocket engines, nuclear reactors, petroleum Chemical and other industrial areas. However, there are still major technical problems in the processing and forming of nickel-based superalloy pipes: (1) Due to the high strength of the material and poor material fluidity, when using ordinary conical die structures and lubrication methods to hot-extrude pipes , due to the poor extrusion process, severe cracks in the tube billet, difficult forming, and high production rejection rate; (2) The hot extrusi...
