Research and Development of Vacuum Degassed Chromium (High Purity Chromium) to Contribute to National Revival

In recent years, China's aerospace industry has developed rapidly, and the moon landing project and large aircraft project have shown achievements one after another, but why can't the engines on fighter planes be made domestically?

The engine is the power of aircraft flight, known as the "heart" of the aircraft, which is very important to the development of aviation. For a long time, my country's aero-engine industry has been controlled by others. Even if various types of engine components can be manufactured, there is a huge gap in performance, service life, and reliability, which is why we cannot get around it at present. Heart disease. Why is there such a big gap in aviation engines in China? According to industry sources, the reason is also the difference in key aviation materials, which is the problem of the industrial system, not to improve the design concept, structure and other aspects can make up for, want to fundamentally solve the problem of heart disease of aviation engines have to start from the basic raw materials. Take metal chromium as an example. Metal chromium is an engineering material with heat resistance, heat strength, wear resistance and special properties. It is also the main material for aero engines. At present, the metal chromium used in the western mainstream aviation hair materials is "vacuum degassed chromium (also known as high purity chromium)", with a purity of 99.9%, low oxygen, low carbon and low impurities. In response to the strict technical blockade imposed by western countries on China, how to produce vacuum degassed chromium in large quantities has always been the dream of China's aerospace industry. Although major domestic scientific research institutes, state-owned enterprises, and industry giants are trying their best to promote the production and research of vacuum chromium, due to technical conditions, equipment, safety, and production personnel, etc., there has been no production capacity and Breakthrough progress has been made in product quality stability.

Jinzhou Keluo New Materials Co., Ltd. holds the belief of contributing to the great rejuvenation of the Chinese nation! A production management team composed of elite personnel with more than 10 years of production experience in the field of high purity chromium has been set up. After many experiments and production accumulation, it has mastered the core technology of producing vacuum degassed chromium such as powder metallurgy and vacuum degassing, and has the ability to quickly organize production. The company now has a domestic advanced vacuum degassed chromium (commonly known as high purity chromium) production line with a production capacity of 300t/a; An advanced degassed chromium powder production line with a production capacity of 150t/a; A metal chromium powder production line specially serving welding materials with a production capacity of 300t/a. Our company has a high degree of quality responsibility and strict quality assurance system, product quality is better than the same industry at home and abroad.

The rise of Coro new materials means that another key material production technology of aero-engine is completely autonomous, and it also breaks the foreign monopoly on China's high-purity chromium production technology, which will greatly meet the application of aero-engine materials and target chromium powder industry.
