Problems solved by technology

my country's conventional titanium alloy vacuum smelting technology has been explored and improved for decades, and the production process route is stable and the process method is mature. There are currently two main methods in the industrial smelting of titanium alloys containing high melting point elements: the first is to directly add high melting point elements. Electron beam cold hearth furnace smelting of metals has high yield and uniform composition, but there are disadvantages such as large investment in equipment, high energy consumption, high cost, complicated operation, and limited ingot weight. use this method
The second is to ad

Embodiment 1

[0012] Grade 1 sponge titanium, aluminum beans and Φ35×2800mm Nb smooth round rods are used as raw materials, and the electrode is prepared according to the nominal composition Ti-45Al-10Nb (wt%). The electrode block is made of sponge titanium and aluminum beans. After the layers are arranged and pressed, the size of the electrode block is 300×130×90mm, and a semicircular electrode block with a surface groove of Φ35mm is welded into a single row of 8 sections with a length of 2800mm, and then Nb round rods are embedded in the groove. The electrode block is multi-point welded, and then the electrode block is covered and welded to form the whole electrode (see attached picture 1). The whole electrode mandrel and the electrode block are combined compactly, with a unit weight of 100Kg, which meets the requirements of a Φ280mm water-cooled copper ingot. The size requirements of the crucible for the electrode, the subsequent selection of a suitable vacuum consumable arc melting proce...

Embodiment 2

[0014] Grade 1 sponge titanium, industrial grade sponge zirconium and Φ35×2800mm Nb light round rod are used as raw materials, and the electrode is made according to the nominal composition Ti-13Nb-13Zr (wt%). The electrode block is made of sponge titanium and sponge zirconium. Arranged in layers and then pressed, the size of the electrode block is 300×130×65mm, and the surface groove is a semicircle of Φ35mm. The electrode blocks are welded into a single row of 8 sections with a length of 2800mm, and then Nb round rods are embedded in the groove. The head section and the electrode block are welded at multiple points, and then the electrode block is covered respectively and welded to form the whole electrode (see attached figure 1). The whole electrode mandrel and the electrode block are combined compactly, with a single weight of 160Kg, which meets the requirements of an ingot The Φ220mm water-cooled copper crucible has the size requirements for the electrode, and then selects...

Embodiment 3

[0016] Grade 1 sponge titanium, aluminum beans and Φ35×2800mm Nb smooth round rods are used as raw materials, and the electrodes are made according to the nominal composition Ti-6Al-7Nb (wt%). The electrode block is made of sponge titanium and aluminum beans. Pressed after layer arrangement, the size of the large electrode block is 300×130×80mm, one surface groove is a semicircle of Φ13mm, the other surface groove is a semicircle of Φ35mm, the size of the small electrode block is 300×130×40mm, and the electrode blocks are welded into a single A row of 8 sections with a length of 2800mm, and then embedded Nb round rods in the groove, and multi-point welding between the two end sections and the electrode block, and then correspondingly covering the electrode block and welding to form a whole electrode (see Figure 2). The combination of electrode mandrel and electrode block is compact, with a unit weight of 135Kg, which meets the size requirements of the Φ280mm water-cooled copper...
