Problems solved by technology

This getter layer deteriorates the deformation properties of the alloy
[0004] to combine figure 1 In the prior art, the blanking process for titanium alloy ingots is usually through heating, blank forging, secondary heating, secondary forging deformation, inspection, machining, bar preparation, and even under some performance requirements, it will also Including three times of heating and three times of heating forging deformation process, prolonging the billet opening process of titanium alloy ingots, the corresponding cost is also increased a lot
[0005] However, in addition to strictly controlling the quality of the production process in the production of titanium alloy materials, the low-cost, high-efficiency, and short-process titanium and titanium alloy processing technologies are the keys to the wide application of titanium alloys in various industries. The current cost is still very high. High, low-cost preparation has been paid more and more attention by research and development departments and titanium production enterprises. Excellent performance, good surface quality and high material yield are currently a key issue in the production and preparation of titanium alloy rods.

Abstract

The present invention provides a high-efficiency titanium and titanium alloy ingot short-flow precision forging blanking process, including heating process, radial forging machine precision forging deformation, inspection and machining process, and then obtain titanium alloy rods: the heating process described therein The heating of titanium and titanium alloy ingots is achieved by using a ring-shaped heating furnace and flame heating. During the heating process, three stages of preheating, heating and soaking are used. The heating temperature of the preheating section is 800±50°, and the heating The heating time is 60-70min; the heating temperature of the heating section is 900-1150°, the heating time is 70-90min, the heating temperature of the soaking section is equivalent to that of the heating section, and the soaking time is 60-90min; Precision forging is carried out by a hydraulic radial forging machine, and four hammerheads are used for hammer forging, and the forging time is 10-30min. The invention adopts an annular heating furnace with an improved heating method, and realizes rapid, efficient, and short-process preparation of titanium and titanium alloy ingots by means of annular segmental heating and combined with forging deformation of a radial forging machine.

Description

technical field [0001] The invention relates to the technical field of forging titanium and titanium alloy rods, in particular to a high-efficiency titanium and titanium alloy ingot casting short-flow precision forging blanking process. Background technique [0002] Compared with copper, aluminum, iron and nickel in the heating process of titanium and titanium alloys, the thermal conductivity of titanium is low. The main difficulty in heating is that when the surface heating method is used, the heating time is quite long, and when large billets are heated, the cross-sectional temperature difference is large. Unlike the thermal conductivity of copper, iron, and nickel-based alloys, which decrease with the increase of temperature, the thermal conductivity of titanium alloys increases with the increase of temperature. [0003] However, when the heating temperature is increased, titanium and titanium alloys also react strongly with air. Titanium reacts strongly with oxygen when...
