Description
Technical field
The invention belongs to titanium and its alloy work technical field, is related to a kind of production method of titanium tube.
Background technology
Titanium or titanium alloy is a kind of important structural metal to grow up the 1950s, and titanium alloy is because having intensity
High, the features such as corrosion resistance is good, heat resistance is high, is widely used in every field, the production method of titanium tube is extruding, rolling, weldering
Connect-roll, although the application prospect of titanium alloy is preferable, current titanium alloy is easily broken in production and processing, causes pipe
Material yield rate is low.
The content of the invention
It is an object of the invention to provide a kind of production method of titanium tube, titanium tube yield rate is higher made from this method.
The technical solution adopted in the present invention is a kind of production method of titanium tube, to specifically comprise the following steps：
Step 1, it is raw material from TC4 titanium alloys；
Step 2, TC4 titanium alloy raw materials are made by pipe using melting, forging and extrusion process；
Step 3, pipe made of step 2 is rolled, drawing and annealing；
Step 4, straightening processing is carried out to the titanium tube after step 3 processing.
The features of the present invention also resides in,
Wherein pipe is preheated before step 3 is carried out, 200~300 DEG C of preheating temperature.
The passage wherein rolled in step 3 is 9~12 passages.
Annealing temperature is 350~400 DEG C wherein in step 3.
Wherein the operation of rolling is carried out in argon atmosphere in step 3.
The invention has the advantages that the present invention employs annealing when processing titanium tube, make crystal grain refinement, tissue
Arrangement is uniform, it is ensured that titanium tube has the performance of temperature, in addition, carried out in the operation of rolling in argon atmosphere, argon gas neither with gold
Category chemical reaction, is also not dissolved in metal, regardless of heat of desorption during high temperature.Titanium tube yield rate made from method provided by the invention compared with
It is high.
