Titanium alloy ingots are the core raw materials in high-tech fields such as aerospace and medical, and their quality is based on melting technology. At present, vacuum consumable arc melting (VAR) is the most widely used process. It melts titanium alloy electrodes through a high current arc in a vacuum environment and solidifies them into ingots by dropping them into a water-cooled copper crystallizer. VAR technology is mature, but its ability to remove high-density inclusions in raw materials is limited.
To produce higher end ingots, electron beam cold bed melting (EBCHM) and plasma cold bed melting (PACHM) technologies have emerged. Both of these technologies utilize the "cold bed" effect, which allows the metal liquid to have a residence and refining process before crystallization and solidification, effectively removing inclusions and allowing for the use of more return materials, significantly improving the purity and economy of the ingot. In actual production, the "double" or "triple" melting process (such as EB+VAR) is usually used, combining the advantages of different technologies to ensure the ultimate chemical composition uniformity and metallurgical quality of the ingot.
