Exploration Of The Smelting Process Of Titanium Alloy Parts

In the pouring process of titanium alloy parts, we often use an efficient and unique smelting method-self-consuming electrode vacuum shell furnace smelting. The reason why this smelting method is named "vacuum condensed shell smelting” is because in the water-cooled copper crucible, a solidified layer of titanium will be formed during the smelting process, as if a protective shell is put on the titanium liquid so that it does not directly come into contact with the water-cooled copper crucible. In this way, pollution from the crucible can be completely avoided and the purity and quality of titanium alloy parts can be ensured.

Although the vacuum self-consuming electrode condensed shell arc smelting technology has many advantages, such as simple structure, low maintenance costs, and easy to large-scale, it has been widely used in the titanium foundry industry, but it also has some shortcomings that cannot be ignored. For example, it has certain requirements for the shape of raw materials, waste materials are difficult to recycle and reuse, and the smelting speed will be subject to certain constraints. However, it is precisely because of its significant advantages that this technology still dominates the smelting of titanium alloy parts.

In addition to vacuum self-consuming electrode condensed shell arc smelting, there is also a method of induction heating smelting titanium castings. This method can directly use waste or sponge titanium as a smelting raw material, which has high flexibility. However, its equipment cost is relatively high and its production efficiency is low, so it is subject to certain restrictions in practical applications. Nevertheless, with the continuous progress of science and technology and the gradual reduction of costs, induction heating smelting methods still have broad prospects for development in the future.

In the smelting process of titanium alloy parts, we also need to pay attention to the control of key parameters such as smelting temperature and smelting time. The precise control of these parameters has an important impact on the micro-structure and performance of titanium alloy parts. At the same time, the atmosphere control in the smelting process is also essential to avoid oxidation or pollution of titanium alloy parts during the smelting process.

In addition, with the widespread application of titanium alloys in aerospace, medical, chemical and other fields, the quality and performance requirements for titanium alloy parts are also getting higher and higher. Therefore, we need to continuously explore and innovate the smelting process of titanium alloy parts to meet the needs of titanium alloy parts in different fields.

In short, the smelting process of titanium alloy parts is a complex and important process. Through continuous research and practice, we can continuously optimize and improve this process to provide more reliable technical support for the production of titanium alloy parts.
