Embodiment 1
[0014] The large-thickness and ultra-wide TA1 titanium plate of this kind of ingot adopts the following specific process.
[0015] Choose a titanium plate that is 20mm thick and 3000mm wide to be a material, and install a heating furnace. The furnace pressure of the heating furnace is slightly positive pressure 6Pa, the oxygen content is 2%, and the heating is carried out; the temperature of entering the furnace is 300°C, and the temperature is kept for 1.5 hours; it takes 1.5 hours to raise the temperature to 680°C; finally, the holding time is 1 hour at 680°C. After the heat treatment of the finished ingot, the titanium plate is air-cooled after being released from the furnace.
[0016] The ultra-wide titanium plate obtained in this example has a good shape (flatness is controlled at ≤1.5mm / m), yield strength Rel: 250MPa, tensile strength Rm: 330MPa; elongation 40%, yield 98%. It meets the needs of subsequent production of titanium parts with special specifications.
Embodiment 2
[0018] The large-thickness and ultra-wide TA1 titanium plate of this kind of ingot adopts the following specific process.
[0019] Choose a titanium plate that is 25mm thick and 3100mm wide to form a material, and install a heating furnace. The furnace pressure of the heating furnace is a slight positive pressure of 8Pa, and the oxygen content is 3%. The heating is carried out; the temperature of entering the furnace is 330°C, and the temperature is kept for 1.2 hours; the temperature is raised to 700°C in 1.2 hours; and the holding time at 700°C is 1.2 hours. After the heat treatment of the finished ingot, the titanium plate is air-cooled after being released from the furnace.
[0020] The ultra-wide titanium plate obtained in this example has good shape (flatness is controlled at ≤1.8mm / m), yield strength Rel: 245MPa, tensile strength Rm: 315MPa; elongation 40%, yield 99%. It meets the needs of subsequent production of titanium parts with special specifications.
Embodiment 3
[0022] The large-thickness and ultra-wide TA1 titanium plate of this kind of ingot adopts the following specific process.
[0023] Choose a titanium plate that is 27mm thick and 3150mm wide to be a material, and install a heating furnace. The furnace pressure of the heating furnace is slightly positive pressure 10Pa, the oxygen content is 3%, and the heating is carried out; the furnace temperature is 350°C, and the temperature is kept for 1 hour; the temperature is raised to 710°C in 1 hour; After the heat treatment of the finished ingot, the titanium plate is air-cooled after being released from the furnace.
[0024] The ultra-wide titanium plate obtained in this example has a good shape (flatness is controlled at ≤2.5mm / m), yield strength Rel: 240MPa, tensile strength Rm: 315MPa; elongation 37%, yield 99%. It meets the needs of subsequent production of titanium parts with special specifications.
