Problems solved by technology

At present, the production process route of vacuum smelting of titanium materials is stable and the process method is mature. In terms of refractory metal smelting, there are mainly electron beam cold hearth furnace smelting and vacuum consumable arc smelting. High, uniform composition, but there are disadvantages such as large equipment investment, high energy consumption, high cost, complicated operation, and limited ingot weight. Vacuum consumable arc melting alloys containing refractory metal elements, the melting method is simple to operate and uniform in composition , but there are also disadvantages such as low yield, high cost, and the need to make master alloys in advance, increasing production processes, production costs, material loss, etc.

Embodiment 1

[0008] Example 1: Using grade 1 sponge titanium, aluminum beans and molybdenum round rods as raw materials, proportioning according to the nominal composition Ti-8Al-15Mo, after mixing the materials, pressing them into electrode blocks, and then welding the electrode blocks by argon arc welding Electrodes for smelting are melted three times in a vacuum consumable arc melting furnace into Φ440mm ingots. Use a quick forging machine to forge the ingot at 1150°C, and after several times of upsetting and drawing, it will become a Φ110mm round billet, and then carry out precision forging at a temperature below 980°C to become a Φ60mm round billet, and finally the machine will be peeled off. After grinding and repairing, it is rolled into Φ8mm wire rod, then ground or repaired to remove scale, and then drawn into Φ2mm wire rod through roller die drawing and cold drawing.

Embodiment 2

[0009] Example 2: Using grade 1 sponge titanium, industrial grade zirconium sponge and niobium round rods as raw materials, proportioning according to the nominal composition Ti-13Nb-13Zr, after mixing the materials, pressing them into electrode blocks, and then welding the electrode blocks with argon arc Methods Welded into electrodes for smelting, and smelted into ingots three times in a vacuum consumable arc melting furnace. Use a fast forging machine to forge the ingot at 1050°C, and after several times of upsetting and drawing, it becomes a δ50mm square slab, and then rolls it below 950°C to become a δ5mm slab, and finally sandblasting, repairing, After pickling, cold-roll the plate to the required thickness.

Abstract

The present invention relates to a preparation method of a titanium electrode containing a metal mandrel difficult to melt, and provides a titanium electrode preparation method which enables the vacuum self-consuming arc melting production cost, the production processes and the energy consumption to be reduced and the yield to be improved. The electrode is composed of the electrode blocks and the metal mandrel difficult to melt, and the metals difficult to melt are combined and welded into a square rod or a round rod of which the length is 2.1-2.7 m. The electrode blocks are formed by pressing the titanium sponges and other metals needing the middle and low melting points, are in layered arrangement and have a certain of grooves on the surface, and the lengths of the electrode blocks are 300-350 mm, and the widths are 200-400 mm. After the two electrode blocks are aligned and welded, a hole cavity for accommodating the metal mandrel difficult to melt is formed, the metal mandrel difficult to melt and the electrode blocks are spliced and welded into the electrode, and the metal mandrel difficult to melt and the grooves of the electrode blocks are combined compactly after splicing and welding. The preparation method of the present invention is suitable for not carrying out the additional intermediate alloy manufacturing and containing the metals difficult to melt directly to prepare a vacuum self-consuming arc melting electrode.

Description

technical field [0001] The invention relates to a method for preparing a titanium electrode comprising a refractory metal mandrel. Background technique [0002] Titanium has the advantages of high strength, low density, excellent corrosion resistance and biocompatibility, and has been widely used in many fields of national economy and social life. At present, the production process route of vacuum smelting of titanium materials is stable and the process method is mature. In terms of refractory metal smelting, there are mainly electron beam cold hearth furnace smelting and vacuum consumable arc smelting. High, uniform composition, but there are disadvantages such as large equipment investment, high energy consumption, high cost, complicated operation, and limited ingot weight. Vacuum consumable arc melting alloys containing refractory metal elements, the melting method is simple to operate and uniform in composition , but there are also disadvantages such as low yield, high ...
