The first hot rolling titanium alloy seamless tube with large diameter wall ratio in China

Recently, Baogang Group successfully tried to produce a specification of 406 mm outer diameter, wall thickness of 16 mm, brand TA10 titanium alloy seamless tube, this is the first domestic production of large diameter wall ratio titanium alloy seamless tube by hot rolling process.

Titanium alloy tube blank is expensive, the trial production of only a feeding. In the face of the narrow thermal deformation temperature window of titanium alloy material, the perforated steel is easy to stick, and the product surface quality requirements are high technical difficulties, baotou Steel has solved the problems such as temperature maintenance in the whole process of titanium alloy hot rolling seamless tube, the deformation rate of punch and hot rolling quality control through technical discussion and careful planning in the early stage, and succeeded in a trial production.

The single-fire forming process used by Baotou Steel in the production of large-wall-ratio titanium alloy seamless tube can not only improve the production efficiency and yield of titanium alloy seamless tube produced by hot rolling process, but also effectively ensure the application performance of titanium alloy seamless tube products. The successful trial production proved that Baotou steel in the field of seamless tube technology level advanced, but also for high-quality development to provide technical reserves and development power.
