Innovation and application of titanium and titanium alloy melting technology

With the rapid development of modern science and technology, titanium and titanium alloys are more and more widely used in industrial production. In order to meet the demand for titanium and titanium alloy materials in different fields, the melting technology has undergone continuous innovation and breakthrough. The following is a detailed description of the representative innovations in titanium and titanium alloy melting technology in recent years.
1. Vacuum self-consumption melting technology for titanium alloys with direct addition of high melting point metals
In the process of vacuum self-consumption arc melting of titanium alloys, the method of directly adding high melting point metal, through the selection of suitable vacuum self-consumption arc melting process, can be melted to meet the requirements of the ratio calculation, the composition of the uniformity of non-segregation of high-quality ingots. The key to this technology lies in the combination of electrode blocks and the welding of high melting point metal rods suitable for the shape of the electrode blocks' grooves.
2. Vacuum self-consumption melting process of titanium and titanium alloys with restarting arc after power failure
In response to possible power failures during the melting process, the technology realizes fast and accurate restarting of the arc by means of a specific current adjustment strategy. This not only significantly reduces the total restart time, but also prevents the formation of gaps between the ingot and the crucible wall as well as internal shrinkage holes.

3. Melting Recovery Method for Pure Titanium Lump Scrap
In order to efficiently utilize the pure titanium lump scrap, an electron beam cold bed furnace is used for melting. This method eliminates the need for tedious steps such as scrap crushing and electrode pressing, which greatly improves the recovery efficiency and speed.
4. E-beam cold bed melting and recycling method for titanium and titanium alloy flake scrap
For titanium and titanium alloy scrap, the appropriate proportion of scrap is weighed and mixed with other raw materials and pressed into electrode blocks, which are then smelted in an E-beam cold bed smelting furnace. This method can produce qualified titanium alloy ingots from up to 90% of the scrap.
5. Melting method for clean titanium and titanium alloy ingots
In order to achieve clean and high quality ingots, the technology uses a specific melting vacuum and melting speed to ensure that the ingots are chemically homogeneous and free of high melting point inclusions.
6. Melting method for titanium alloys containing high melting point alloying elements
The technology uses multiple vacuum self-consumption arc melting to obtain titanium alloy ingots with uniform composition and high melting point alloying elements by selecting specific raw materials and electrode block assembly. This method is low cost, high efficiency and suitable for industrialized production.
7. Method of preparing TC4 titanium alloy ingots by electron beam cold bed furnace melting
For the melting preparation of TC4 titanium alloy, this technology adopts Ti-Al intermediate alloy instead of aluminum beans, which reduces the volatilization of Al element and improves the utilization rate of raw materials and the efficiency of electron beam cold bed furnace. At the same time, the method also improves the cleanliness and quality of titanium alloy ingots.
The innovation and application of these technologies not only improve the production efficiency and material quality of titanium and titanium alloys, but also provide more high-performance titanium and titanium alloy material options for different fields. With the continuous progress of science and technology, we have reason to believe that titanium and titanium alloy melting technology will continue to usher in more innovations and breakthroughs.
