Examples
example 1
[0017] This example produces a titanium alloy seamless pipe with a specification of Φ110×14mm.
[0018] A titanium alloy (wherein Ti is the balance) whose composition is shown in Example 1 in Table 1 was forged by melting to produce a Φ200 round tube billet. Heating the round tube blank with a ring heating furnace, setting the furnace temperature of the ring heating furnace at 1105°C, and holding time for 60min, so that the temperature of the round tube blank is 1105±5°C. Subsequently, the round tube billet was cross-rolled and pierced to obtain a capillary tube, and the capillary tube was continuously rolled to form a 180×14 blank tube, and the blank tube was air-cooled to room temperature. The waste pipe enters the reheating furnace, heats the waste pipe to 880±5°C, and the holding time is 20min. After exiting the reheating furnace, the waste tube was tension-reduced by a two-roller tension reducer, and the tension-reduction deformation was 39%, and a titanium alloy seamles...
example 2
[0021] This example produces a titanium alloy seamless pipe with a specification of Φ89×7mm.
[0022] The titanium alloy (where Ti is the balance) whose composition is shown in Example 2 in Table 1 was melted, cast into an ingot, and forged to produce a Φ160 round tube billet. Heating the circular tube blank with a ring heating furnace, setting the furnace temperature of the ring heating furnace at 1110°C, and holding time for 50min, so that the temperature of the circular tube blank is 1105±5°C. Subsequently, the round tube billet was cross-rolled and pierced to obtain a capillary tube, and the capillary tube was continuously rolled to form a 140×7 blank tube, and the blank tube was air-cooled to room temperature. The waste pipe enters the reheating furnace, heats the waste pipe to 880±5°C, and the holding time is 10 minutes. After exiting the reheating furnace, the blank pipe is subjected to tension reduction by a two-roller tension reducer, and the tension reduction deform...
example 3
[0024] This example produces a titanium alloy seamless pipe with a specification of Φ73×6mm.
[0025] The titanium alloy (where Ti is the balance) whose composition is shown in Example 3 in Table 1 was melted, cast ingot, and forged to produce a Φ160 round tube billet. Heating the round tube blank with a ring heating furnace, setting the furnace temperature of the ring heating furnace at 1180°C, and holding time for 40min, so that the temperature of the round tube billet is 1175±5°C. Subsequently, the round tube billet was cross-rolled and pierced to obtain a capillary tube, and the capillary tube was continuously rolled to form a 120×6 blank tube, and the blank tube was air-cooled to room temperature. The waste pipe enters the reheating furnace, heats the waste pipe to 870±5°C, and the holding time is 8 minutes. After exiting the reheating furnace, the waste pipe was tension-reduced by a two-roller tension reducer, and the tension reduction deformation was 39%, and a Φ73×6mm...
