Chapter 573 Large Forging Press (asking for monthly ticket)

Chapter 573 Large Forging Press (asking for monthly ticket)

Of course, China does not have an 80,000-ton die forging press now.

But in recent years, Southwest Aluminum Processing Plant and Deyang Erzhong have developed extremely rapidly with the support of Panshan Group.

In addition to the original 30,000-ton die forging hydraulic press, Southwest Aluminum Processing Plant has also built a 30,000-ton die forging hydraulic press and a 15,000-ton die forging hydraulic press.

In addition to the original 12,000-ton free forging hydraulic press, Deyang Erzhong has also built a 31,500 die forging press and a 45,000-ton die forging press.

It is precisely with these large die forging presses that China's processing capacity for forgings such as aluminum alloys, titanium alloys, high-temperature alloys, and powder alloys has been greatly improved.

Large die forging presses have always been an important symbol of a country's industrial strength.

Large die forging presses are mainly used for hot die forging and isothermal superplastic forming of difficult-to-deform materials such as aluminum alloys, titanium alloys, high-temperature alloys, and powder alloys.

Its forging characteristics are that it can improve the density of deformed materials through high pressure, long holding time, and slow deformation speed, and improve the comprehensive performance of forgings by refining material grains, improve the deformation uniformity of the entire forging, and make difficult-to-deform materials and complex structure forgings meet design requirements through isothermal forging and superplastic deformation, which can save 40% of materials and achieve the goal of less machining or near net shape.

In the past, there were still many countries in the world that could build airplanes. Now, there are only a handful of countries that can build airplanes. One very important reason is that isothermal forging presses are key equipment for the production of important forgings in aviation, aerospace, aerospace and other important machinery.

In order to improve the overall performance of aviation products, the proportion and unit size of large die forgings in aviation forgings are getting larger and larger.

For the overall structure of the main load-bearing frame and beam of the aircraft, at least 30,000 large die forging hydraulic presses are required for processing.

The aircraft of the Soviet Union and the United States are processed by large die-forging hydraulic presses of 40,000 to 75,000 tons.

In recent years, the performance of China's J-7, H-6, Y-8 and other military aircraft has been greatly improved. In addition to the development of China's electronic industry, which has improved the avionics system of the aircraft, a very important reason is the processing of large die-forging hydraulic presses.

If you want to produce more advanced fighters and passenger aircraft, you can't do without large die-forging presses.

Large die-forging presses are regarded as an important symbol of a country's industrial strength. Naturally, they belong to strategic control materials. No country is willing to sell large die-forging presses.

The United States will not sell them, and the Soviet Union will not sell them.

Other countries either develop large die-forging presses themselves; or pay the processing fees and ask others to process them. Being strangled by others can give a fatal blow at a critical moment.

Now China has a 45,000-ton die-forging press, which naturally means that it can process the main bearing frame, beams and other integral components of large aircraft and process qualified components.

As for funds, Panshan Group is now rich and powerful, so it will not be lacking.

Although launching the Jinsha River's four major hydropower stations, the Three Gorges Project and other century-long projects requires a lot of expenditure, this economic crisis has really made too much profit, enough to support these century-long projects.

There is even a large amount of funds left!

It is also because of sufficient funds that Liu Tao thought of domestic large aircraft.

Unfortunately, looking at this information, it is worse than he originally expected.

Even Liu Tao is now unsure. After the team has been disbanded for a few years, will these technicians be abandoned?

If they are abandoned, that would be the most troublesome.

But no matter what, Liu Tao has no intention of giving up the large aircraft project.

From a strategic point of view, this project is related to national defense security. If a large aircraft is developed, it can launch an impact on early warning aircraft, military transport aircraft and other aspects.

Although China can now purchase passenger aircraft from Boeing and Airbus, the purchase price is not low, and secondly, it is strangled.

Liu Tao does not want the future Chinese sky to be full of Boeing and Airbus aircraft.

The future Chinese passenger aircraft market is also promising. In 30 to 40 years, there will be a demand for at least 5,000 aircraft. This is a huge market. Liu Tao does not want this big piece of fat meat to be eaten by Boeing and Airbus.

This day.

A man with gray hair came to Panshan Group with expectation in his eyes.

If you are in the aviation field, you will recognize him when you see him. He is the chief designer of Yun-10 - Ma Fengshan!

Ma Fengshan was transferred to Xi'an Aircraft Manufacturing Plant in 1964. He participated in the imitation of the H-6 aircraft, the analysis of the impact of the aircraft dropping atomic bombs, hydrogen bomb shock waves and light radiation on the mother aircraft, and served as the chief technical person in charge of the design of the Yun-8 aircraft. He organized and led the planning and design of the aircraft, formulated the general surveying and mapping design plan, and determined major change projects, laying the foundation for the later surveying and mapping trial production of the Yun-8 aircraft.

In 1970, the state gave Shanghai the task of developing a large passenger aircraft, the Y-10. Ma Fengshan was transferred to Shanghai 708 Design Group to participate in the design of the Y-10 aircraft and served as the chief technical officer. In 1979, he was appointed chief designer and in July 1982, he became the director of Shanghai Aircraft Research Institute.

In the face of great difficulties and pressure, Ma Fengshan united and led the engineering and technical personnel to send the Y-10 into the blue sky in less than ten years, achieving a breakthrough in the history of my country's aviation industry for large jet aircraft.

Due to long-term overload work, he became ill due to overwork and rested in 1982. In 1985, because the test flight of the Y-10 was completely suspended, Ma Fengshan led a team to the McDonnell Douglas Aircraft Company in the United States to participate in the high bypass ratio technology cooperation research.

After he got the news this time, he immediately returned from the United States.

He had naturally heard about the Panshan Group and was full of hope.

To be honest, Ma Fengshan found it difficult to accept the cancellation of the Y-10.

He invested countless efforts in the Y-10, which was equivalent to his child and more important than his own life.

His biggest dream was to successfully develop the Y-10 and let the Y-10 aircraft soar in the blue sky of the motherland.

Especially this time when he went to the United States and saw the advanced aviation industry in the United States, Ma Fengshan was extremely determined. If possible, he was willing to exchange his life for the success of the Y-10.

Before coming, Ma Fengshan had been told that the Y-10 project was about to be restarted.

This made Ma Fengshan's heart burn with hope again.

The cancellation of the Y-10 project has always been the biggest pain and regret in Ma Fengshan's heart.

He just hoped that this time it was not fate playing a joke on him.

After calming down, Ma Fengshan walked towards the Panshan Group headquarters building. After a series of identity verification and registration, Ma Fengshan was taken to the top floor by the staff.

When he entered the elevator, the elevator rose very steadily and the sound was very small, which shocked Ma Fengshan.

And when he reached the top floor, Ma Fengshan was even more shocked.

Because here, he saw the operation mode of modern enterprises, which was very different from other state-owned enterprises.

He seemed to see hope all of a sudden!
