The EB furnace put into production this time has undergone more than 9 months of installation and commissioning by the project team. The first trial run will be carried out in July 2020. The equipment volume is 32500×18000m×14000mm, and it can smelt round ingots, cylindrical ingots and slabs. Being a domestic leader can further enhance the company’s supply capabilities in the domestic and international aviation, aerospace industry and civilian fields.

In recent years, with the rapid development of the aerospace and aviation industries, there is an increasing demand for high-quality titanium alloys at home and abroad, which has also made the smelting technology of vacuum cold gun electron beam cooling bed furnaces that are energy-saving and economically stable. The wider the application. Different from the vacuum consumable electric arc furnace, the electron beam cooling bed furnace can fully remove high and low density inclusions, ensuring the absolute purity of the titanium alloy material, and providing quality assurance for high-end applications such as aerospace; at the same time, the electron beam cooling bed furnace It can accept a large amount of residual titanium raw materials, further improve the utilization rate of raw materials, and greatly reduce production costs. The commissioning of the 3150KW EB furnace further improved the company’s “EB+VAR” smelting process route, marking the company’s breakthrough in the production of high-quality and high-stability titanium alloys for aerospace use, which can satisfy more domestic and foreign aviation industries. Aerospace customers’ demand for titanium alloy smelting.
