Embodiment 1
[0019] The selected composition is Ni: 56wt.%, Ti: 44wt.% binary nickel-titanium memory alloy, the raw materials are 0 grade sponge titanium and 1# electrolytic nickel, weigh 56kg electrolytic nickel and 44kg sponge titanium (three groups), each One group is all loaded into the crucible of the vacuum intermediate frequency induction melting furnace. After evacuation (the pressure is less than 0.1pa), turn on the electric heating, heat the raw materials to between 1300°C and 1800°C to melt them all, and keep them for 15 to 60 minutes for refining. It is then poured into a circular mold, and the primary ingot is taken out after cooling, and the three primary ingots are pressed into figure 2 Cut the size of medium and round ingots, and then press image 3 The cloth is welded to form the secondary electrode. Then, use a vacuum consumable electrode arc melting furnace to melt the secondary electrode, and finally the riser part adopts the feeding process of conventional titanium ...
Embodiment 2
[0023] The selected composition is Ni: 55wt.%, Ti: 46wt.% binary nickel-titanium memory alloy, the raw materials are 0 grade sponge titanium and 1# electrolytic nickel, weigh 55kg electrolytic nickel and 46kg sponge titanium (three groups), each One group is all loaded into the crucible of the vacuum intermediate frequency induction melting furnace. After evacuation (the pressure is less than 0.1pa), turn on the electric heating, heat the raw materials to between 1300°C and 1800°C to melt them all, and keep them for 15 to 60 minutes for refining. Then it is poured into a square mold, and the primary ingot is taken out after cooling, and the three primary ingots are pressed into figure 2 Cut the size of the square ingot, and then press image 3 The cloth is welded to form the secondary electrode. Then, use a vacuum consumable electrode arc melting furnace to melt the secondary electrode, and finally the riser part adopts the feeding process of conventional titanium alloy mel...
Embodiment 3
[0027] The selected composition is Ni: 55.5wt.%, Ti: 44.2wt.%, Cr: 0.3wt.% ternary nickel-titanium memory alloy, the raw materials are 0-grade sponge titanium, 1# electrolytic nickel and electrolytic chromium, weighing 55.5kg Electrolytic nickel, 44.2 kg of titanium sponge and 0.3 kg of electrolytic chromium (three groups), each group is fully loaded into the crucible of the vacuum intermediate frequency induction melting furnace. After evacuation (the pressure is less than 0.1pa), turn on the electric heating, heat the raw materials to between 1300°C and 1800°C to melt them all, and keep them for 15 to 60 minutes for refining. It is then poured into a circular mold, and the primary ingot is taken out after cooling, and the three primary ingots are pressed into figure 2 Cut the size of medium and round ingots, and then press image 3 The way cloth is welded to form the secondary electrode. Then, use a vacuum consumable electrode arc melting furnace to melt the secondary ele...
