With the continuous development of titanium alloy smelting technology, it is more and more necessary for intermediate alloys to replace elemental metals directly into titanium for smelting. It tends to melt first and is easy to evaporate. Titanium has a high melting point and a small specific gravity. It floats on the tin, resulting in the phenomenon of falling blocks and causing low-density inclusions and high-density inclusions in the alloy ingot, resulting in uneven and unstable alloy composition. Necessary improvement

Embodiment 1
[0020] The conventional vacuum consumable furnace is used for smelting, and the raw materials are cleaned, dried, batched according to the stated percentages, smelted, vacuum cooled, released from the furnace, sampled for analysis and packaged.
[0021] Concrete preparation process is as follows:
[0022] 1. Ingredients, weighing the raw materials, by percentage, tin is 75%, and the balance is titanium sponge with a particle size of 0.8-11.0mm;
[0023] 2. Dry the titanium sponge at 65-105°C before use, and clean the tin block with alcohol and ultrasonic waves;
[0024] 3. Put the two kinds of metals into the vacuum consumable furnace in proportion and melt them under vacuum conditions; when the vacuum degree of the vacuum consumable furnace is less than 1.0Pa, start to smelt with electricity, heat the metal block to 800-1550°C, and keep it warm for 35 -55 minutes, and filled with argon 0.09-0.06Mpa.
[0025] 4. Casting after smelting, in order to prevent oxidation, vacuum c...

Abstract
The invention provides a preparation method of a titanium-tin intermediate alloy of a superconducting line. The method comprises the following steps: 1) weighing the following raw materials in percentage by weight: 72 to 78 percent of tin, and the balance of titanium sponge; 2) baking the titanium sponge at the temperature of between 65 and 105 DEG C, and cleaning a tin block; 3) placing the two metals in a consumable-electrode vacuum furnace, and smelting in a vacuum condition; 4) casting after smelting, cooling for 20 to 45 minutes in vacuum, discharging and demoulding; and 5) scalping the surface by using a lathe. In the method, titanium and tin are added in a binary alloy, complexity of singly and respectively adding a metal elementary substance can be avoided, the preparation of titanium alloy has a stable smelting process, low-density inclusion and high-density inclusion occurring in alloy cast ingot caused by a chipping phenomenon due to the fact that the metal elementary substances have discordant melting points are avoided, uniformity and stability of the cast ingot components are easily controlled, the production cost is low, alloying is uniform, the intermediate alloy is easily broken, and the preparation cost of the titanium alloy is reduced.
Description
technical field [0001] The invention belongs to the technical field of titanium alloy preparation, and in particular relates to a preparation method of a superconducting wire titanium-tin master alloy. Background technique [0002] Different alloying elements are usually added to titanium alloys to improve the performance of the alloy. The addition of tin can strengthen the alloy and improve the plasticity without reducing the strength. With the continuous development of titanium alloy smelting technology, it is more and more necessary for intermediate alloys to replace elemental metals directly into titanium for smelting. It tends to melt first and is easy to evaporate. Titanium has a high melting point and a small specific gravity. It floats on the tin, resulting in the phenomenon of falling blocks and causing low-density inclusions and high-density inclusions in the alloy ingot, resulting in uneven and unstable alloy composition. Necessary to improve. Contents of the i...
