Embodiment 1

[0071] This embodiment provides a high-efficiency and high-throughput preparation method for titanium alloy (TF400) titanium rods, including the following steps:

[0072] Feeding: Pour 68.53kg of titanium sponge, 1.19kg of Fe particles, and 0.28kg of Fe-B intermediate alloy into the melting chamber along the feed pipe, close the vacuum valve, and fill with argon after rough and fine pumping to 0.5Pa Gas protection gas.

[0073] Alloy melting and splitting: Activate the plasma gun to melt the raw material to a liquid state.

[0074] Splitting and solidification: After the melt flows into the splitting chamber, turn on the heating device to ensure that the temperature of the melt is between 1200-1350°C to avoid cooling down of the melt. The high-temperature melt flows into the three crystallizers through the diversion gap, and each mold is wrapped with a 7YSZ thermal barrier coating to ensure that there is no heat conduction and heat influence between different molds, and the t...

Embodiment 2

[0080] This embodiment provides a high-efficiency and high-throughput preparation method for Ti-6Al-4V rods, including the following steps:

[0081] Feeding: Pour 63kg of sponge titanium and 7kg of Al-V intermediate alloy into the melting chamber along the feeding pipe, close the vacuum valve, and fill it with argon protective gas after rough and fine pumping to 0.5Pa.

[0082] Alloy melting and splitting: Activate the plasma gun to melt the raw material to a liquid state.

[0083] Splitting and solidification: After the melt flows into the splitting chamber, turn on the heating device to ensure that the temperature of the melt is between 1400-1500°C to avoid cooling down of the melt. The high-temperature melt flows into the three crystallizers through the diversion gap, and each mold is wrapped with a 7YSZ thermal barrier coating to ensure that there is no heat conduction and heat influence between different molds, and the thermal uniformity of a single mold is guaranteed.

Description

technical field [0001] The invention relates to the technical field of titanium alloy preparation, in particular to a high-efficiency and high-throughput continuous casting and rolling system for titanium alloy rods. Background technique [0002] Titanium alloy has the advantages of high specific strength, good corrosion resistance and machinability, and is often used as a structural material in ships and marine engineering. The use of titanium alloys on ships can greatly improve the service life of ships and realize Reduce weight and increase load, reduce ship maintenance costs. In marine engineering, titanium alloy rods can be used as supports to improve corrosion resistance in marine environments, reduce corrosion of building components such as piers and slope protection in seawater environments, and increase service life. However, the current preparation of titanium alloy rods results in an unexpected cost of titanium raw materials, and the long processing cycle also li...
