An iron alloy composed of molybdenum and iron, generally containing 50 to 60% molybdenum, is used as an alloy additive in steelmaking. Ferromolybdenum is an alloy of molybdenum and iron. Its main use is as an additive for molybdenum in steelmaking. The addition of molybdenum to the steel can make the steel have a uniform fine-grained structure, and improve the hardenability of the steel, which is conducive to eliminating temper brittleness. In high-speed steel, molybdenum can replace part of tungsten. Molybdenum and other alloying elements are widely used in the production of stainless steel, heat-resistant steel, acid-resistant steel and tool steel, as well as alloys with special physical properties. Molybdenum is added to cast iron to increase its strength and wear resistance.

Compared with the "Shenzhou VI", this "嫦娥探月" is facing an unprecedented new technical challenge, and Great Wall lubricants once again accompanied the No.1, overcoming the various lubrication problems during the lunar exploration process, and also showed people Great Wall lubricants independently researched and focused on the future research spirit, and set a goal for China's lubricant industry to serve China's aerospace business strategy, independent innovation, strengthen basic research, and create an innovative country for China.
Compared with civil lubricants, aerospace lubricants need to maintain stable and reliable quality under the conditions of high temperature difference, high radiation, strong oxidation, vacuum and other complex and variable conditions, and have become one of the important technologies in aerospace lubrication technology. At present, only a few countries in the world such as the United States and China have the ability to produce aerospace lubricants. With the aerospace lubrication technology, the scientific research strength and product quality of Great Wall Lubricants have reached the international leading level.
“China is at the forefront of the world in the field of aerospace lubrication technologyâ€
"嫦娥一å·" God, the experts of the Great Wall lubricants are particularly excited and nervous. Great Wall Lubricants has served China's space industry for nearly 50 years. It has escorted China's first launch vehicle, the first artificial satellite and the Shenzhou-5 and Shenzhou-6 spaceships.
"Chang'e No. 1 is much more demanding than Shenzhou No. 6." Great Wall lubricant technology expert Zhao Jiang revealed that "there are many new environments and requirements that have never been encountered before." The moon is 400,000 kilometers away. In addition, Chang'e-1 has been in the lunar orbit for one year. Such long-term operation is a great challenge for all equipment and instruments.
In space flight, the spacecraft must maintain a very good seal. In 2003, Great Wall Lubricants developed high and low temperature greases, providing a lubrication between solid and liquid lubrication. It has excellent sealing and adhesion and is used in the spacecraft's co-rotation reducer. .
When the rocket is launched, the fuel used contains special media such as liquid hydrogen, liquid oxygen and other strong oxidants. Only special lubricants can resist the erosion.
“These technologies are only available in a few countries around the world,†he said. “With the development of this series of aerospace lubricants, China has been at the forefront of the world in aerospace lubrication technology.â€
"Never let lubricants become the limiting factor of China's space industry"
Compared with ordinary civilian equipment, space exploration equipment and instruments from the factory, transport, launch, orbit to space operation, to experience a variety of harsh environments that are unimaginable. It must undergo extraordinary mechanical vibration, shock, noise, overweight and acceleration. It should withstand vacuum, high and low temperature, weight loss, solar radiation, particle radiation, electromagnetic radiation, oxygen, cosmic dust, etc. during orbital operation. The role of the environment.
In the early days of the space age, the service life of mechanical components in space was much lower than the service life of the ground, which greatly limited the service life of the entire spacecraft. With the development of aerospace technology and the advancement of electronics, the use of mechanical components Life has been greatly extended, and lubrication should not be a "killer" that limits the life of spacecraft.
"We will never let lubricants become a constraint factor for China's aerospace industry." Zhao Jiang said, "The current space lubrication development plan has at least 10 years of forward-looking vision, fully reflecting the guiding role of the scientific development concept in the sustainable development of scientific research. ."
At present, Great Wall Lubricants has formed a series of lubrication products that can meet the current development of China's aerospace industry, including fluorine-containing grease products, instrument oils, precision bearing oils, greases for harmonic reducers, etc., which are world-leading in technology.
“Large state-owned enterprises shoulder national responsibility and political responsibilityâ€
As the world's fourth and Asia's number one lubricant brand, 2006 Changcheng Lubricants sold more than 1.4 million tons of lubricants, and broke the long-term international brand monopoly of high-end automotive lubricants market, not only led the successful rise of China's lubricant industry It also provides Chinese consumers with more products that are suitable for China's road conditions and more cost-effective.
The civilian use of aerospace lubrication technology has become a magic weapon for Great Wall lubricants to occupy the high-end market. Space precision bearing lubricants for gyro motors on spacecraft have been directly applied to gyroscopes in many large ships. The synthetic oil production technology mastered in the research and development of aerospace lubricants is widely used in weapons, steel metallurgy, electrical appliances and instruments. The new textile machinery requires high temperature (200 ° C ~ 250 ° C), high speed, long life synthetic grease, Great Wall lubricants rely on aerospace technology to develop high temperature chain oil, breaking the monopoly of foreign companies in the industry.
“As a leading brand of lubricants national enterprises, we have the responsibility to lead the rapid development of China's lubricant industry and provide better products to Chinese companies and individual consumers.†Zhao Jiang said, “As a large state-owned enterprise, we also Responsible for state responsibility and political responsibility."
Aerospace technology has become an important stage for the competition of world powers. As the most complicated and difficult mega project in the world today, the aerospace industry has put forward tremendous requirements for basic scientific research and has become the driving force for the sustainable development of the national economy. The US "Apollo Moon Landing Program" has trained a generation of high-level scientists for the United States, which has led to the comprehensive development of high-tech computers and communications in the United States in the 1960s and 1970s. In addition, the space industry is also concerned with national defense security and national strategy. According to experts, modern warfare from intelligence reconnaissance to surveillance, from weather forecasting to the use of precision-guided weapons, from communications to computer defense, uses space in almost every respect. The significance of controlling space is even greater than missile defense.
At present, Great Wall Lubricants has built two R&D centers and four national-level laboratories. In the past two years, it has obtained domestic and foreign technical certification/approval and more than 100 product specifications, and has the largest pipe transfer in Asia. The world's most advanced production system, such as system, high-speed barrel and canned integrated production line.
It is foreseeable that under the general trend of adhering to independent innovation, the development of aerospace lubrication technology will make greater contributions to China's aerospace industry, as well as the improvement of lubricant technology in the civilian sector, and even the entire national science and technology. Progress has produced even greater impetus.
The "Chang'e-1" lunar exploration satellite was successfully launched on October 24, and the dream of the Chinese people's millennium and the moon became a reality.
