Aircraft carriers, as a major weapon of the country, are mobile fortresses on the ocean, and aircraft carrier steel plates are the indestructible foundation of this fortress.

It not only has to withstand years of erosion by seawater, but also has to withstand the fatal strike of missiles in the midst of war. Its high toughness, magnetic repellency, and low temperature resistance are all challenges to the extreme of materials science.

The most amazing thing is that it can still maintain its original shape under the test of high temperatures. When the carrier-based aircraft roared from the deck, the flames from the tail seemed to melt everything, but the aircraft carrier steel plates could stand in the sea of fire. How tough and great it is to stand still!

Behind the steel plates of the aircraft carrier lies a country's profound industrial strength and advanced technological level.

Once upon a time, the production technology of aircraft carrier's steel panel was firmly controlled by the world's four major countries—the United States, the United Kingdom, France, and Russia, forming an insurmountable technological gap.

When China decided to transform the Varyag and embark on the journey of aircraft carrier construction, upon asking Russia to purchase aircraft carrier steel plates, Russia decisively rejected the request under the excuse of military secrets.

Western countries have imposed a strict technology blockade on China in an attempt to exclude China from the ranks of major aircraft carrier-building countries.

In the face of external blockade and suppression, China chose not to yield, instead resolutely embarking on the road of independent research and development.

Scientists know deeply that behind the aircraft carrier steel plate is a contest of national dignity and security. They study day and night and conquer technical difficulties one after another.

During development, China's greatest challenge was not the lack of extra-wide heavy plate mills, but the manufacturing technology for high-quality large-tonnage slabs. This kind of slab is the core of aircraft carrier steel plates, and its quality directly determines the strength of the aircraft carrier.

After numerous attempts and improvements, China has finally made a breakthrough in this field, successfully developing an electric slag remelting furnace with a capacity of 6000 tons for producing ultra-thick, high-strength steel slabs that are at the world's advanced level, which can be used for aircraft carriers with a single weight of 50 to 100 tons.

Today, China has successfully joined the ranks of countries globally that can independently build aircraft carrier steel plates, and has made remarkable achievements in this field. Since

From Liaoning to Shandong and then to Fujian, the launching of each aircraft carrier is the best demonstration of China's steel plate manufacturing technology for aircraft carriers.

Not only did we break the technological blockade of Western countries, but we also won the respect and recognition of the world with our own strength.

Finally, I would like to say that the achievements made by China in the R&D of aircraft carrier steel plates are not only a technological triumph, but also a triumph of the spirit.

It shows the self-improvement and innovative spirit of the Chinese people to the world and also proves that as long as we unite and work together, we can overcome any obstacles in our progress. This spirit will inspire us to move forward on our future path and create more glories!
