At present, the "high-power, high-frequency and high-voltage power supply", the main functional device of the electron gun independently developed by Qinghai enterprises, has been mass-produced. After the localized device is applied to the electron beam cooling bed furnace for titanium metal production equipment, it runs smoothly and has achieved a cumulative achievement. The sales revenue of titanium and titanium alloy ingots is 352 million yuan. This move provides effective experience for improving the localization of my country's electron gun functional devices, accelerating the market application of the precious metal "titanium" and reducing industry costs.
Electron guns are the main equipment for the production of titanium and titanium alloys. With "titanium" as an important strategic metal playing a pivotal role in the national economy and national defense, the smelting, and purification of titanium directly affect the quality and safety of aviation flying nuclear weapons. For a long time, only Germany, Britain, France, and other countries have conducted in-depth research on EB furnace smelting equipment. Due to technical limitations, domestic titanium metal production enterprises have equipment from abroad, which has brought a series of development obstacles to Chinese enterprises.
Qinghai Juneng Titanium Industry Co., Ltd. is the only high-tech state-owned enterprise specializing in the production and processing of titanium and titanium alloys in Qinghai Province. In 2016, the 20-ton titanium ingot produced by Qinghai Juneng Titanium became the largest single titanium ingot in the country and even in Asia.
In order to get rid of the long-term status of being "subject to others", 5 years ago, the company started to implement the "E-beam cooling bed smelting furnace R&D and industrialization" project. After nearly two years of hard work by experts and technicians from various fields, at the end of 2014, The company successfully broke through the key technology of electron gun and "high-power, high-frequency and high-voltage power supply" core bottleneck technology, and manufactured prototypes. The project passed the acceptance check this year. The localized electron gun and power cabinet developed by the project have better performance than imported equipment, and are maturely applied to imported equipment at a cost of only 20% of foreign equipment.
"Compared with the traditional vacuum consumable electric arc furnace, the EB furnace has a strong ability to remove high and low-density inclusions, and the ingot does not produce segregation. The EB furnace gradually replaces the vacuum consumable electric arc furnace is an inevitable trend of future development. ." Tang Zenghui, general manager of the company, introduced.
