Liu Zhengdong
Let's get closer.
"Tsinghua people in the heavy weapons of a great country".Series.
Tell you about the reform and opening up.
Tsinghua people are the most important weapons of the country.
The story of the struggle of silent cultivation.
Give up the high salary and resolutely return to China
1966 year.
Liu Zhengdong was born in Tuquan County, Xing'an League, Inner Mongolia Autonomous Region.
During the college entrance examination, he was admitted to Tsinghua University with excellent results.
It's localThe first student to be admitted to Tsinghua University
TsinghuaActions speak louder than wordsschool spirit.
Trained Liu Zhengdong to treat scientific research.
Serious, persistent and pragmaticattitude.
More to himThe spirit of not being afraid of difficulties and tenacious struggle
In 1986, Liu Zhengdong and his father were in Beijing.
Year 2001.
Zhengdong Liu to the University of British Columbia.
Pursue a PhD in Metallurgical Engineering.
After completing your studies. himSuccessively give upThe United States, Canada and other countries.
scientific research institutionsHigh-paying hiring
Resolutely returned to China
Determined to be"Do something for the Motherland".
Ultra-supercritical power generation technology
It is under the national conditions of China's rich coal, poor oil and low gas.
An important way to achieve high-quality development of power engineering.
Year 2001. , when Liu Zhengdong returned to China.
Ultra-supercritical thermal power in China.
and the million-kilowatt nuclear power project has not yet started.
and the key raw materials for the development of these technologies.
NamelyHigh-pressure boiler tubes and large forgings for nuclear useWait.
Monopolized by foreign technology
Resulting in abnormally high **.
You can't even buy it with money.
It has threatened China's energy security
Liu Zhengdong identified.
Solve the problem of "stuck neck" in this field
That's what he's going to do
From being blocked by foreign technology to leaping to the forefront of the world
It's hard to get started
When Liu Zhengdong first returned to the General Iron and Steel Research Institute.
study groupThere were only 4 people
While raising funds for pre-research.
While forming a research team.
600 ultra-supercritical
is so far
The world's most advanced commercial coal-fired power generation technology
If China's thermal power crosses from subcritical to 600 ultra-supercritical.
Annually availableLess electric coal23.2 billion tons
Emission reduction CO2 5100 million tons
Economically, environmentally and strategically significant.
In order to achieve a "leapfrog" of thermal power
Since 2003.
China began to build 600 ultra-supercritical power stations.
It's also the year.
Liu Zhengdong got it.
The first national scientific research mission for boiler tube research
In 2009, Liu Zhengdong visited the Brazilian Mining and Metallurgical Company.
Boiler tubes must be exposed to a variety of corrosive environments at high temperature and high pressure.
long-term stable service".
R&D is difficult and the cycle is long
In order to realize the leap from "0 to 1".
Liu Zhengdong and the team.
Fight after battle.
Level after level.
After more than 10 years of tackling
Realized China's ultra-supercritical key boiler tubes.
From nothing
From there to all(complete boiler tubes for the whole boiler).
Leap from full to advanced
Make our boiler tube manufacturing technologyLeap to the international advanced level
It has completely changed the market pattern of the world's heat-resistant steel pipes
Now. The number of 600 ultra-supercritical power stations built in China.
It accounts for more than 90% of the world's most advanced coal-fired power stations of its kind.
From being stuck in the neck by foreign countries to jumping to the forefront of the world
Liu Zhengdong led the team.
Write a strong stroke.
"No matter how good a disruptive technology is
If you only stay at the level of technological development
It's also useless".
Liu Zhengdong was soberly aware.
The gold content of the neck jam technique
The key lies in the value of engineering applications
At the same time as completing the boiler tube research.
Liu Zhengdong's team invented.
Currently the only one in the worldCan be used in engineering.
630 Ultra-supercritical coal-fired power stations.
Manufactured with large-diameter thick-walled pipes.
New martensitic heat-resistant steelg115
It solves its engineering application problems
It is used in Yuncheng, Shandong
The world's firstConstruction of 630 ultra-supercritical demonstration power station.
Make China's ultra-supercritical power station technology world-leading
Furthermore. Liu Zhengdong's team.
It also solves the key components of China's pressurized water reactor nuclear project.
Part of the engineering and technological problems in construction.
Realization of China's pressurized water reactor nuclear project
Autonomy of the main equipment and material technology of the nuclear island
Liu Zhengdong won the 2017 National Innovation Competition.
How steel is made
Mention grades. Liu Zhengdong prefers to take credit.
This great era and big team.
"Science can be the performance of an individual's talents
Engineering must be a display of the results of teamwork".
He leads the whole industry team of power plant power steel.
In the past 20 years, we have insisted on tackling advanced heat-resistant steels and alloys.
The whole team was convinced
Every freshman who enters Zhengdong Liu's group.
The most important thing to keep in mind is.
A "beginner's talk with peace of mind".
Liu Zhengdong will start with the feelings of his family and country.
On the strategic significance of ultra-supercritical power stations.
Talk about the urgency of the construction of major power station projects.
Talk about the "stuck neck" problem of heat-resistant steel pipe products.
Talk about the deeds of the older generation of scientific and technological workers.
Talk about his scientific research experience......
Although there is no specific research content.
But after the talk, everyone was in high spirits.
Determined to beShoulder the mission and dedicate to the country
Achieve a career in hard work
In 2015.
Liu Zhengdong obtained.
Ho Leung Ho Lee Science and Technology Innovation Award.
Soon after. He and his wife Zhao Kui.
Donated 100,000 yuan to set up a scholarship in his hometown middle school.
Reward students with excellent character and academic performance.
Hopefully they get good results.
Give back to the motherland in the future
The beneficiary students and class teachers took a group photo.
Steel is tempered in intense fire and sharp cooling.
Therefore it is sturdy".
Liu Zhengdong is like the steel he studied.
In the process of constantly overcoming difficult challenges.
Turn difficulty into height.
Turn resistance into power.
Impressive results have been achieved.
Conquer one after another.
Seemingly impossible hurdles.
Help China to be more "steel".
