Abstract

The invention discloses a method for producing a titanium alloy seamless tube through intelligent temperature control. The method comprises the following steps of (1) preparing materials, specifically, a titanium alloy bar meeting the standard is selected, and the titanium alloy bar is machined into a round blank with a proper diameter; (2) performing heat treatment, specifically, heat treatment is performed on the machined solid tubular titanium alloy round blank, the machined solid tubular titanium alloy round blank is heated to 915-970 DEG C, and the titanium alloy round blank obtains a needle-shaped mixed structure by adjusting a heat treatment process; and (3) machining centering holes, specifically, after the titanium alloy round blank is subjected to heat treatment, the centering holes in the two ends of the titanium alloy round blank are machined, and the surface of the blank is coated with a protective coating, so that the produced titanium alloy seamless tube has relatively good plasticity, thermal stability and fatigue strength, and also has relatively high endurance strength, creep strength and fracture toughness; and the outer wall of the titanium alloy seamless tube is coated with the anti-corrosion and anti-rust coating, so that the protective effect is achieved, the using quality of the titanium alloy seamless tube can be improved, and the service life of the titanium alloy seamless tube can be prolonged.

Description
