He, the deserving 'Iron Man', regards the steel mill as a family and hones it for 10 years to produce super steel

Materials are known as the mother of invention, steel, the grain of industry, and the backbone of a great nation. In 1996, China's crude steel production exceeded 100 million tons, and China's steel industry officially entered a period of rapid development. Since then, China has not only maintained the world's largest crude steel production for 26 consecutive years, but also continuously broken through categories. Today, it has been able to smelt more than 1000 steel grades, including high-temperature alloys and precision alloys, and roll and process over 4000 specifications of steel, which is unparalleled worldwide.

In 1999, with the support of the national "973" project, Wang Guodong, academician of the CAE Member, and his team, without adding any alloy, made the strength of steel significantly improved by relying only on controlled rolling and cooling. Since then, as a common key technology in the steel industry, controlled rolling and cooling technology has quickly become the standard configuration of major steel enterprises. Led the rapid upgrading and upgrading of Chinese steel in a short period of time, providing strong support for the rapid construction of China Bridge, China Road, and China Tower. Academician Wang Guodong is also revered as the immortal 'Iron Man'.

As soon as I arrive at the steel factory, I feel like I'm going home

Wang Guodong doesn't like being given too many titles by others. He believes, "To be a person, one must be down-to-earth

The surging steel flowers splashed day and night, and the majestic rolling mill roared in waves... This is Wang Guodong's favorite and most familiar scene. Raise the "backbone" of the national steel, so that the "important tool of the country" is no longer subject to human control. Wang Guodong is willing to strive for it all his life!

Working day and night in the workshop, I have drawn several sketches

The calendar on the desk records the busyness of this 80 year old academician: every year, about half of his time is spent on the front line, participating in project argumentation, exchanging technical solutions, and promoting the implementation of new technologies... Wang Guodong said, "As soon as he arrives at the steel factory, he feels like going home

Wang Guodong, who grew up in Anshan, has a "steel complex" ingrained in his bones. In 1950, 8-year-old Wang Guodong came to Anshan with his parents. At that time, all he heard and witnessed were bustling construction sites, construction projects with frequent reports of success, and towering steel workers

I grew up listening to the deeds of the old heroes Meng Tai, Wang Chonglun, and the universal tool tire, Zhang Mingshan, and the anti encirclement wheel, "Wang Guodong said. In order to study his favorite major, he applied for the Steel Pressure Processing major in the Department of Iron and Steel Metallurgy at Northeast University of Technology when filling out his university application.

At that time, I could introduce the blooming mill, semi continuous mill, and rail beam mill to my relatives and friends like a book, telling them how huge steel ingots turned into billets and how solid steel rods turned into seamless steel pipes in piercing machines. Years later, Wang Guodong recalled his youth and spring years with endless nostalgia in his heart.

After graduation, Wang Guodong was assigned to a small factory at Ansteel. He spent 10 years there. Small factories have difficult production conditions, high labor intensity, and high risks. He started with basic work in the workshop, working with the masters to clamp and change rollers

At that time, the factory produced blanks for the front axles of Jiefang Automobile and Huanghe Automobile. Due to the absence of a feeding device, the rolled piece cannot bite into the roller, resulting in two incomplete cycles at the head and tail, with a yield rate of no more than 75% and a significant waste of raw materials. Wang Guodong took the initiative to ask for help, continuously translated multiple foreign literature, and formed a technical innovation team with three experienced workers to carry out technical research.

I can't remember how many times I failed. Working day and night in the workshop, I drew several sketches, and finally achieved the linkage between the rolling piece feeding device and the rolling mill transmission system, ensuring the yield rate. "Speaking of this paragraph, Wang Guodong smiled on his face.

After 10 years of grassroots life at Ansteel, Wang Guodong gained an understanding of China's steel industry, steel workers, and steel industry. The harsh environment of small factories and the expectations in the eyes of their masters have become a powerful driving force, making me realize the multiple responsibilities on my shoulders! "Wang Guodong said.

In October 1978, Wang Guodong was admitted to Beijing Iron and Steel Research Institute and became a master's student of renowned steel rolling expert Professor Zhang Shutang. After graduation, Wang Guodong returned to his alma mater, Northeast Institute of Technology, to teach.

When we can't eat or sleep, research results are about to come out

Steel is the backbone of a great country. Ten years of honing in the steel industry have given Wang Guodong a deeper understanding: "We need to seek new processing techniques, which not only significantly improve the performance of steel materials, extend their service life, but also improve the utilization and recovery rate of resources

In 1998, with the support of the national "973" plan, Wang Guodong's team began the project of "basic research on achieving grain refinement during the rolling process". After multiple experiments, it has been shown that refining grains can significantly improve yield strength, which is very detrimental to the plasticity of the material. At that time, the difficulty of processing and manufacturing was also significant.

To focus our research on achievable goals, we proposed the concept of moderate grain refinement, "said Wang Guodong.

The mind changes and the world widens. Wang Guodong and members of the research team have been stationed at the front line of the factory for a long time, conducting laboratory experiments, analysis, calculations, conducting on-site research, discussions, and developing experimental plans.

When we can't eat or sleep, scientific research results are about to come out! "Recalling those years, Wang Guodong didn't feel bitter because he vaguely saw the light in front of the tunnel.

However, the greater challenge is how to implement laboratory research results on industrial rolling mills. Through research, Wang Guodong learned that Baosteel's 2050 hot strip mill was the only internationally advanced hot strip mill in China at that time. The members of the research group have been working at Baosteel for more than 10 years, and have a thorough understanding of the rolling mill from hardware equipment to computer systems. After careful argumentation and risk analysis, experts from all parties have reached a unified conclusion: approve the experiment!

In September 1999, an on-site rolling experiment was conducted on the 2050 hot strip mill of Baosteel to refine the grain size of SS400 steel. This was the first experiment in the world to roll super steel using an industrial rolling mill. When the testing machine showed the qualified mechanical performance indicators of the material, the comrades of the research group and the on-site engineering and technical personnel cheered and hugged tightly together.

Super steel is born!

The application of super steel has effectively reduced resource consumption, saving the country at least hundreds of millions of yuan in expenses every year. But Wang Guodong always said, "Super steel is just a ripple in the wave of material revolution. Turn this page over! Looking forward, that's the surging sea

From the application for establishment in 2012 to the official operation in 2015, Wang Guodong, who is over 70 years old, once again took on the heavy responsibility of the "2011 Steel Common Technology Collaborative Innovation Center". The 981 drilling platform, Guanyinyan large-scale power plant, new generation ships, the thick walled pipeline of the Liwan deep-sea oil and gas field in the South China Sea, high-tech ships sailing in the Arctic Ocean, and the "Hualong No.1" third-generation nuclear power technology global first demonstration project... These glorious "national treasures" embody the hard work of the Wang Guodong team, and are also their pride in their hearts.

Young people have unlimited creativity, and we need to build a stage for them to showcase their talents

The motto of Wang Guodong is to write a paper on the land of our country and engrave the achievements on the steel production line of our country. He always encourages students and scientific researchers to have a down-to-earth spirit of struggle, strive for projects that are not deceived or boasted, spend funds that are not focused or wasted, have the courage to innovate independently, and contribute to the self-reliance and self-improvement of science and technology in the national steel industry.

When it comes to students, Wang Guodong is very pleased: "Students are my 'young comrades in arms', and they are working hard to grow into towering trees

Wang Guodong has a requirement for students: "Don't learn from a thousand schools, just seek to excel in one skill", and use his "unique skills" to serve the steel industry. In order to achieve this goal, Wang Guodong will "invest" young people in the production line, allowing them to grow their talents in practice.

Wang Guodong provided a rare opportunity for young people in the construction of Baosteel's 1580 hot rolling mill project. During the installation and debugging phase of this contemporary advanced rolling mill, Wang Guodong arranged for young teachers and graduate students to delve into the frontline. Day and night, they wear work clothes, debug, put into production, and improve, working together with Baosteel people

At the beginning, Baosteel was not sure whether the students could overcome the difficulties, but Wang Guodong was full of confidence: "Young people have unlimited creativity, and we need to build a stage for them to showcase their talents

More than a year later, the students mastered the essence of technology, not only achieving the goal of reducing waste volume by 30%, but also overfulfilling the task, reducing waste volume to 50%. After graduation, the students who participated in the research project stayed at Baosteel and became the young business backbone of the enterprise.

Liu Zhenyu is a Mesozoic force of Wang Guodong's team. His team collaborated with Baosteel Ansteel to develop green steel intelligent manufacturing technology, effectively solving the contradiction between the current large-scale production of steel enterprises and the personalized needs of users.

At that time, there were very few graduate students and only two in the department. Teacher Wang was very serious in every lecture and prepared a thick lesson plan for both of us, "Liu Zhenyu recalled.

Over the years, the State Key Laboratory of Rolling Technology and Continuous Rolling Automation of Northeastern University led by Wang Guodong has trained more than 200 doctoral students for the country. Some of these young people are active in China's metallurgical plants and become a new generation of material processing experts; Some teach in universities and become the main force of China's education front; Some are studying abroad and preparing to return to their country in the future to contribute to their country

The research and development history of super steel is a history of continuous innovation and breakthroughs

It is also a history of significant contributions to national economic development, technological progress, and national defense security.
