【Preface】
In the process of China's development, it has experienced too many things that have been "stuck in the neck" by technology, but the mainland has never complained about it, nor has it languished, and has been in a "desperate situation" countless times, shining in the sanctioned fields.
From a backward country that was invaded and suppressed all the way to becoming the world's largest developing country, we have made tremendous efforts, and no one can feel the bitterness of it.
And now we have achieved a new breakthrough in the field of technology, a complete rise that has broken the monopoly and sanctions imposed on us by some Western countries for 30 years.
And we not only broke the monopoly, but also became the world's first in this field and led the world's development.
The leaps and bounds we have made have also made some Western countries wonder how we did it, so they also want to import some products from the mainland to study.
But as the saying goes, "it's not polite to come and go", after we mastered this patented technology, we also formulated a policy to permanently ban exports to Europe and the United States.
This made many netizens shout "awesome my country", so what is this technology and what kind of charm does it have?
【Break the monopoly】
The technology in which we broke 30 years of Western sanctions is hand-tearing steel.
Some people may not know much about what hand-torn steel is, it is a stainless steel that is a quarter thinner than A4 paper, this stainless steel we can tear with our bare hands, it looks like tin foil.
In the process of China's rapid development, it is often called a major producer by some other countries, but we are also a big consumer.
Four or five years ago, only a few countries had the ability and technology to mass-produce this very thin stainless steel.
But its application field is very wide, not only in the field of equipment and instruments, but also in aerospace, new energy, 5G communication and other fields also have a very large demand.
Therefore, the mainland imports a large amount of hand-torn steel from abroad every year, but some Western countries have introduced a new policy for us, that is, only 0.03 mm of "hand-torn steel" is allowed to be exported to China.
However, the production of high-end instruments and equipment requires 0.02mm of "hand-torn steel", even if there is only a 0.01mm gap, but the precision of the instruments that can be produced is completely different.
Our "hand-torn steel" technology is indeed backward compared to some large producers in the West, so it is very easy to be sanctioned by them.
Not only that, the price of the "hand-torn steel" they export to us is also very high, the price per ton can be about twice the market price, and our demand for this technology has basically accounted for more than half of the global "hand-torn steel" market.
Therefore, it costs a huge amount of money to import this technology every year, and some foreign companies even name China and claim that it will never be possible to make 0.02mm hand-torn steel itself.
But the last thing we Chinese lack is the courage and tenacity to lie down and try the courage, we can break through the sanctions once, we can break through countless more, time will tell.
In fact, in 2008, we began to develop and manufacture "hand-torn steel", but at that time, various technologies and equipment were relatively backward.
But our steps have never stopped, and after being "stuck in the neck", the bloody nature of the sons and daughters of China has also been stimulated, and the time and energy spent in this field have reached the point of overload.
In the end it paid off, and in the fall of 2022, we achieved something that surprised the world, and we developed an upgraded version of "hand-torn steel".
It has great innovation and improvement compared to the original in terms of performance and form factor, and can be used in the smartphones and other wearable devices we use.
This is a major breakthrough, and the technicians who developed it said at the time that from the results of the test samples, its quality has exceeded the level of foreign countries.
【The charm of hand-torn steel】
Now our technology in this area has become more and more mature, not only entering the ranks of the world's top level, but also having the confidence and strength of the neck of Kaou America.
But we still haven't stopped pioneering and innovating in this technology, because the world is constantly changing and developing, and only by keeping up with the development of the times can we be evergreen.
The biggest feature of hand-torn steel is that it is thin and soft, compared with ordinary steel, its toughness has a very large advantage, we all know that ordinary steel can not withstand breakage, because there is a great risk of breakage.
However, its biggest advantage over other materials is that even if it is folded tens of thousands of times, it will not break, and not only will it not break without any traces of folding.
The folding screen mobile phone we see in life uses this material, and bloggers with relevant digital tests have said that even if the number of times this folding screen is opened and closed about 100 times a day, it can be used for several years.
There is also the presence of hand-torn steel in the logo material behind the manufacture of Apple mobile phones and tablets, which is not only tough, but also very high temperature resistant.
Because of this feature, it is also widely used in the manufacture of important parts in the combustion chamber blades of engines and jet engines, which can greatly reduce the accidents of equipment during operation, and also reduce the high temperature damage generated during operation.
We all know that during the flight of the aircraft, its temperature will become lower and lower with the increase of altitude, and ice will generally appear on the surface of the aircraft.
At this time, the use of hand-torn steel materials can greatly increase the safety of its flight, which can ensure safety and increase its service life.
In addition, this material has a wide range of indispensable use in the military and new energy fields, in the military, because of its thinness and light weight, it can be used to avoid the detection of the enemy's electronic signals, in terms of new energy, we commonly use common materials of the battery wrapping layer are a large number of hand-torn steel materials.
It can be said that the normal operation of various devices in our lives such as computers and smart homes is inseparable from it, and it is precisely such a wide range of uses that makes Western countries vigorously sanction China.
【Swimming against the current】
But what people didn't expect was that we rushed out against the current under such sanctions.
When we rely heavily on imports, we can really only produce hand-torn steel with an accuracy of 0.05mm, which is a very large distance from 0.02mm in Western countries.
At the beginning, we wanted to import foreign production lines and technologies, but even if they were just production lines, they offered sky-high prices.
The United States even directly monopolized the technology of hand-torn steel to China, saying that it would not provide any technical support to China, and we actually know why.
Because we have mentioned earlier, this technical material has a wide range of applications in all walks of life, especially in the 5G communication that is now competing between countries.
If monopolizing this technology actually indirectly curbs the development of China's intelligent field, then China's progress in the field of science and technology will be affected to a certain extent, and then it can prevent the upgrading of China's science and technology.
This high-precision technology is very difficult to copy, so when trying to break through such technical barriers, we also face various problems.
But we showed perseverance in the face of many difficulties, and this heavy and glorious mission fell on the Northwest Steel Mill in Taiyuan, Shanxi Province.
In the initial stage, many of the process progress was guided by foreign experts invited by us, but unfortunately, after round after round of efforts, we still did not make any progress.
After exhausting the lifelong learning at that time, we can only manufacture 0.3mm thick plates, foreign experts say for a while that it is the reason for the accuracy of the equipment, and then say that it is the reason for the accuracy of the material, in short, only failed again and again.
After four years like this, foreign experts suddenly decided to leave, leaving a sentence that made everyone's mood fall to the bottom instantly: raw materials are similar, talents are similar, management is similar, but it adds up to a lot worse.
The ambitions and rhetoric of the past are still in sight, and our technicians are not willing to give up just like that, this is a mission given by the state, and they must complete it.
The new leader took office in the cold wind, took the place of foreign experts, wiped off their sweat, regained their fighting spirit, and began a new round of R&D and manufacturing.
They had only one advantage, the state-funded world-class steelmaking equipment, which they had to look at after many failures.
They feel that the words of foreign experts are harsh but not unreasonable, so in the new round of production research, they decided to completely abandon the "almost" idea, make each procedure and step perfect, and then pick each link detail by detail.
According to Liao Xi, the core technician at that time, more than 20 processes, hundreds of employees, day and night debated for a month, during which they experienced countless repetitions.
Some even reached the last step, but failed, and when the steel belt that was pressed for more than a hundred meters was instantly shattered into powder, everyone's hearts were instantly shattered into powder.
But in the end, the effort paid off, and after 711 failures, the "hand-torn steel" with a width of 600 mm and a thickness of 0.015 mm was born.
【Conclusion】
And after such achievements, their slogan and purpose still sound inspiring now, that is, "Don't dare to be satisfied!" Can't be satisfied! ”
It's a heart-wrenching story, and now we already have the latest specifications of hand-torn steel, completely developed and manufactured by China itself.
I believe that in the future, our country's high-tech industries will develop vigorously, achieve proud achievements, and have stronger confidence and strength to lead the progress and development of world science and technology.
