High-purity and high-density aluminum-titanium alloy ingot and manufacturing method thereof

[0023] A high-purity and high-density aluminum-titanium alloy ingot, the aluminum-titanium alloy ingot is 15% aluminum-titanium, which contains 83% aluminum, 15.97% titanium and 0.03% impurities.

[0024] The manufacturing method of the above-mentioned high-purity and high-density aluminum-titanium alloy ingot comprises the following steps:

[0025] 1) Raw material preparation

[0026] ① Raw material preparation: Prepare 830Kg of aluminum ingots with a purity of not less than 99.95%, 105Kg of titanium sponge, and 65Kg of recycled waste titanium pins by weight;

[0027] ②Auxiliary material preparation: prepare a sufficient amount of carbon monoxide;

[0028] ③Equipment and tooling preparation: a silicon carbide ceramic hydraulic cylinder with a carbon fiber heating system inside, a silicon carbide ceramic hydraulic rod matched at the input end of the hydraulic cylinder, a silicon carbide ceramic output pipe connected to the output end of the ceramic hydraulic cylinder, and a c...

[0037] The whole is consistent with Example 1, the difference is:

[0038] A high-purity and high-density aluminum-titanium alloy ingot, the aluminum-titanium alloy ingot is 15% aluminum-titanium, which contains 85% aluminum, 13.98% titanium, and no more than 0.02% impurities.

[0039] The manufacturing method of the above-mentioned high-purity and high-density aluminum-titanium alloy ingot comprises the following steps:

[0040] 1) Raw material preparation

[0041] ① Raw material preparation: Prepare 850Kg of aluminum ingots with a purity of not less than 99.95%, 95Kg of sponge titanium, and 55Kg of newly purchased titanium pins by weight;

[0042] 2) Metal liquid acquisition and purification

[0043] ①Put the original aluminum ingot prepared in step ① in 1) into the vacuum electroslag remelting equipment prepared in step ③ of stage 1), and put it in a vacuum degree of 10- 4 Heat in the environment of Pa until the aluminum ingot is completely melted, and then continue to h...
