Tube/Pipe Production System
Aero-Ti mainly produces titanium seamless pipes, titanium elbows, titanium welded pipes, and chemical pipes, with an annual output of 1,500 tons. The annual output of titanium alloy seamless tube can reach 800 tons/year.
Coil Pilger Mill
The rolling of titanium alloy seamless tube is generally processed by reciprocating (peel format) cold tube rolling machine. In the process, two-roll (LG) and multi-roll (LD) mills are generally used for multi-pass rolling. In the deformation process of titanium pipe, wall and diameter are gradually reduced along with the rotation and feeding of the rolling mill. The pipe of unit length is generally rolled for 5 to 10 times in a rolling pass and finished to obtain the pipe size specification required by the process. Cold rolling mill can be used for large diameter reduction and wall reduction processing, but after rolling, the dimensional accuracy is low, the pipe end is prone to cracking, uneven concave and convex phenomenon, for cracking phenomenon, mainly through the tube before processing grinding, leveling and other methods to solve; For the occurrence of uneven pipe end, similar to the "fish mouth" phenomenon, in the subsequent processing process should be flat head treatment, otherwise it will cause plug congestion accident, therefore, this paper from the process, tooling, equipment and other aspects of analysis, in order to find out the cause of uneven pipe end concave and convex, take effective measures to solve.
Straightener
We have the largest 180 oblique seven roller waste heat straightener in titanium alloy industry. The equipment can process the diameter of φ80-180mm bar material, the maximum feeding length of 12m. With the world's largest full-flow temperature-controlled rolling production line for titanium alloy bars, the equipment can realize the automatic and continuous production of online waste heat straightening, rounding, calendering and collecting of hot-rolled bars. After straightening, the straightness of bar material is less than 1.5‰, the surface calendering effect is good, and the finished product roundness can be further optimized, the peeling rate can be increased by 50-100%, and the service life of the peeling tool can be prolonged by more than one time..
