Abstract

The invention provides an extrusion die for preparing a nickel alloy bar and a preparation method, and relates to the technical field of nickel alloy bar machining. The extrusion die comprises a heating base connected into a fixing base in a conical surface fit mode, a heating coil is wound in the heating base, and a two-half type extrusion cylinder is connected into the heating base in a conical surface fit mode. A cylindrical stock bin and a cylindrical forming channel which communicate with each other are arranged in the extrusion cylinder, a male die fixed to a movable die plate can enter the stock bin along with movement of the movable die plate and extrude a nickel alloy material into the forming channel, a non-contact thermodetector is arranged close to the stock bin, and the forming channel penetrates through the extrusion cylinder and the bottom end of the heating base. The problem that in the prior art, a hot extrusion nickel alloy bar is poor in economical efficiency and formability is solved.

Description

technical field [0001] The invention relates to the technical field of processing nickel alloy rods, in particular to an extrusion die for preparing nickel alloy rods and a preparation method. Background technique [0002] Nickel alloys refer to alloys in which nickel metal accounts for not less than 50% of the weight of the entire alloy, and common ones include Ni, Ni-Fe, Ni-Cu, Ni-Cr-Co-Mo, etc. Nickel alloys are widely used in the manufacture of components in nuclear power plants, chemicals, aerospace, ships and soda industries due to their excellent acid and alkali resistance, as well as excellent strength and oxidation resistance. At present, the obtaining of nickel alloy rods mainly depends on warm extrusion and hot extrusion forming. Because the extrusion process is carried out under complex high temperature and high pressure, and the special temperature-sensitive characteristics and large deformation resistance of nickel alloys, resulting in During the extrusion pro...
