Description

Technical Field

[0001] The invention relates to the technical field of nonferrous metal ingot materials, in particular to a device for removing volatiles from the surface of a green low-carbon titanium ingot. Background Art

[0002] Titanium and titanium alloys have the advantages of high specific strength, corrosion resistance, good low temperature performance, high thermal strength, etc. They are important structural materials in the aerospace industry and are mainly used in fuselage frames, skins, landing gears, stringers, heat shields and shells on aircraft. With the rapid development of large-scale and integrated titanium alloy materials in aerospace, military industry, marine engineering and other fields, high-quality titanium and titanium alloy products are the future development direction.

[0003] At present, the vacuum consumable arc furnace melting method (VAR) has become the main method for smelting titanium alloys due to its advantages of high purity, high efficiency, low pollution, wide application range, high degree of automation, and strong economy. The smelted ingots have good crystal structure and uniform chemical composition. It is one of the mature titanium and titanium alloy production technologies. However, in actual production, it is found that a large amount of easily peeled surface volatiles and residues are commonly found on the surface of titanium alloy primary ingots produced by vacuum consumable arc furnace melting method. It will have an adverse effect on the ingot yield rate and increase production costs; and it will affect the chemical composition of the finished ingot, especially the oxygen content. And with the upgrading of VAR equipment technology, the diameter size of the ingot that can be melted is increasing, but the corresponding supporting equipment cannot adapt to ingots with a wider diameter size range, and cannot efficiently clean the volatiles and residues on the surface of large-size ingots. In addition, the conventional ingot cleaning device consumes a large amount of water, the water cannot be recycled, and the surface volatiles and residues after cleaning are not recycled, resulting in a waste of resources.

[0004] Therefore, the present invention proposes a green low-carbon titanium ingot surface volatile removal device, which is of great significance for cleaning the surface volatiles and residues of ingots with a wider diameter range, improving the quality of titanium alloy ingots, and promoting the efficiency of resource recycling.
