Introduction of Common Technology of Hot Extrusion of Titanium Alloy Bar


 The hot extrusion of titanium alloy rod  titanium bar is the extrusion of powder under the condition of increasing temperature, so that the product can be fully densified. The hot extrusion method of titanium alloy rod  titanium bar can accurately control the composition of the material and the internal structure of the alloy. Hot extrusion can be divided into two forms: envelope hot extrusion and non-envelope hot extrusion.

For active metal titanium and titanium alloy powder, the envelope hot extrusion method is often used to prevent product oxidation. At this time, first make the jacket, put the powder or billet in the jacket, after pre-pumping and sealing, put it in the extruder for hot extrusion.
  The sheath material used at this time should have good thermoplasticity, not to form full gold with the discharge material, easy to peel off after hot extrusion, convenient source and low cost. Low carbon steel or stainless steel sheet is more commonly used.

The first process of hot extrusion of titanium alloy rod titanium bar is the combination of forming, sintering and hot working, thus the drill products with better mechanical properties can be obtained directly.
   The second process is to form titanium and titanium alloy powder. After sintering, the properties of titanium alloy products were obtained by hot extrusion (for Ti-32Mo alloy, temperature 1000-1100 ℃). The effect of extrusion ratio on the properties of titanium. As can be seen from the table, a titanium material with a theoretical density of 98.6% Mel 99.1% can be obtained.

 The third process of titanium alloy bar titanium bar is the process of filling billet extrusion, which is an important method that can be used to produce products with complex cross section. The process includes: preparing the jacket cavity and determining the cavity size according to the desired final product size plus extrusion coefficient; packing. The powder is loaded into the cavity and shaken by vibration; the emptying, exhaust and sealing of the jacket; extrusion at a certain temperature and extrusion ratio; peeling the envelope.
