Description
Technical field
The present invention relates to a kind of production methods of heavy caliber titanium seamless tubes, belong to metallurgical technology field.
Background technology
With the fast development of Chinese national economy and science and technology, titanium alloy material technology of preparing and product quality obtain
Greatly improve, driven the rapid extension of titanium alloy application field, in recent years to heavy caliber (diameter is more than 300mm) titanium without
The demand of slit-tube material is more and more.Because titanium or titanium alloy is expensive, it is generally desirable to improve titanium seamless pipe to manufacture overall process
Lumber recovery.Currently, heavy caliber titanium tube uses vacuum melting ingot casting through stripping off the skin, being forged into pipe, pipe perforated, hot rolling or crowded again
Pressure production seamless pipe, forging process generally need to be through 3~4 igneous materials, and lumber recovery is between 40%~85%.Nowadays, process it is few, at
High, the at low cost major diameter titanium tube of material rate prepares processing and has become bottleneck, is badly in need of solving.Therefore, it is necessary to develop major diameter
The preparation for processing of titanium tube.
Invention content
The technical problem to be solved by the present invention is to：A kind of production method of heavy caliber titanium seamless tubes is provided, lumber recovery is high,
Process is few, inexpensive.
The technical solution adopted in the present invention is to solve above-mentioned technical problem：The production method of heavy caliber titanium seamless tubes,
Including step：
A, vacuum melting obtains round ingot casting, and outer diameter is not less than 400mm；
B, circle ingot casting outer surface is machined out and is stripped off the skin；
C, electric furnace heating circle ingot casting, heating temperature are set as 5 DEG C~50 DEG C of transformation temperature or more；
D, perforation or hydraulic pressure punching, obtain hollow billet；
E, to vehicle outside boring in hollow billet, bright and clean surfaces externally and internally is obtained；
F, electric furnace or line-frequency induction heat hollow billet, and heating temperature is set as 5 DEG C~50 DEG C of transformation temperature or less；
G, Pilger period milling train hot rolling；
H, sizing mill sizing；
I, it anneals.
The outer diameter that vacuum melting obtains round ingot casting in step A is preferably 400mm~1000mm.
Circle ingot casting outer surface impurity is more, should be generally machined out and be stripped off the skin by step B.
Electric furnace heating circle ingot casting is preferably used in step C.Ingot casting is justified using electric furnace rather than combustion gas stove heat, it can be to avoid titanium
Ingot casting inhales hydrogen.Heating temperature is set as 5 DEG C~50 DEG C of transformation temperature or more, keeps titanium ingot structure preferable for β phases, plasticity, is conducive to wear
Hole or hydraulic pressure punching deformation.
In step D, perforation is generally roll piercing, because having oblique additional deformation, hollow billet tissue poor；Hydraulic pressure punching hollow billet
Three-dimensional compressive stress is born, tissue is preferable, but hydraulic pressure punching cannot be punched through, and there are bottom of a cup, needed to cut off, reduced lumber recovery.It can root
According to actual needs selection hollow billet is obtained by the way of perforation or hydraulic pressure punching.
To vehicle outside boring in hollow billet in step E, the hollow billet surfaces externally and internally Defect removal that perforation or hydraulic pressure punching are generated is clean.
Hollow billet is heated using electric furnace or line-frequency induction in step F, it is preferred to use line-frequency induction heats.Using line-frequency induction plus
Hot hollow billet is the oxidation in order to reduce hollow billet surfaces externally and internally and prevents hollow billet suction hydrogen；To ensure good hot rolling microstructure, it is necessary to will
Heating and temperature control is 5 DEG C~50 DEG C of transformation temperature or less.
The milling train hot rolling of Pilger period is preferably used in step G, is made hollow billet by three-dimensional compressive stress, is conducive to titanium tube hot rolling
Tissue refines, uniformly.
In step H after sizing mill sizing, the outer diameter of titanium seamless tubes is made to meet the requirements, while improving titanium tube ovality.
It anneals to titanium seamless tubes in step I, so that hot rolling microstructure isometry, homogenization.
The beneficial effects of the invention are as follows：The titanium seamless tubes of production have many advantages, such as that lumber recovery is high, process is few, inexpensive, because
This, the present invention provides a kind of new selection for the production of heavy caliber titanium seamless tubes, has broad application prospects.
Specific implementation mode
With reference to embodiment, the invention will be further described.
Embodiment one：Produce the TA2 titanium tubes of φ 325mm × 25mm specifications.
Technological process is：Vacuum melting obtains outer diameter 450mm circles ingot casting → outer surface machining and strips off the skin to obtain outer diameter 440mm
Circle ingot casting → 900 DEG C~910 DEG C electric furnace heating, 5 hours heating times → perforation is at the outer vehicle of φ 440mm × 70mm hollow billets → interior boring
Hollow billet → 860 DEG C~870 DEG C line-frequency induction heating → Pilger period milling train is rolled into φ 338mm × 25mm → sizing into φ
325mm × 25mm → 680 DEG C are annealed 1.5 hours, pickling → finished product.
Embodiment two：Produce the TA1 titanium tubes of φ 480mm × 48mm specifications.
Technological process is：Vacuum melting obtains outer diameter 610mm circles ingot casting → outer surface machining and strips off the skin to obtain outer diameter 600mm
Circle ingot casting → 895 DEG C~905 DEG C electric furnace heating, 6 hours → hydraulic pressure of heating time are punching into φ 610mm × 106mm hollow billets → interior
The outer vehicle hollow billet → 855 DEG C~865 DEG C line-frequency induction heating → Pilger period milling train of boring is rolled into φ 486mm × 48mm → sizing
It anneals 2 hours at 480mm × 48mm → 670 DEG C φ, pickling → finished product.
Embodiment three：Produce the TC4 titanium alloy tubes of φ 406mm × 25mm specifications.
Technological process is：Vacuum melting obtains outer diameter 510mm circles ingot casting → outer surface machining and strips off the skin to obtain outer diameter 500mm
Circle ingot casting → 990 DEG C~1000 DEG C electric furnace heating, 5.5 hours heating times → perforation is at φ 520mm × 71mm hollow billets → interior boring
Outer vehicle hollow billet → 955 DEG C~965 DEG C line-frequency induction heating → Pilger period milling train be rolled into φ 418mm × 25mm → sizing at
406mm × 25mm → 700 DEG C φ are annealed 2 hours, pickling → finished product.
As can be seen from the above embodiments, it is excellent to have that process is few, lumber recovery is high etc. for the titanium alloy tube of the method for the present invention production
