specific Embodiment approach 1
[0012] Embodiment 1: The steps of the method for preparing a near-single crystal ingot of titanium alloy in this embodiment are as follows:
[0013] Step 1, vacuumize the furnace body of the cold crucible electromagnetic restraint forming and directional solidification device, the vacuum degree is 0.05-1Pa, and then backflush argon to 300-400Pa;
[0014] In step 2, a titanium alloy material rod 1 is arranged inside the cavity of the water-cooled copper crucible 2 in the directional solidification device, and an induction coil 3 is arranged outside the water-cooled copper crucible 2. The number of turns of the induction coil 3 is 4, and the wire diameter is 8 mm. , distributed on the outer surface of the water-cooled copper crucible 2;
[0015] Step 3. The titanium alloy material rod 1 enters 2-5 mm of the induction coil 3 under the control of the directional solidification device. The upper end of the pulling rod 37 is provided with a titanium alloy base material 35, the diame...
specific Embodiment approach 2
[0018] Embodiment 2: The upper end of the pulling rod in this embodiment is provided with a titanium alloy base material 35, the diameter of the upper part of the titanium alloy base material 35 is 25-26 mm, the height is 20-20 mm, and the diameter of the lower part of the titanium alloy base material 35 is 29 mm. ~29.5mm, height is 15~18mm. The above data range is convenient for melting, leak proofing and solidification.
specific Embodiment approach 3
[0019] Embodiment 3: The diameter of the titanium alloy material rod 1 in this embodiment is smaller than the diameter of the cavity of the water-cooled copper crucible 2 .
