Although Zhao Jingfu's academic qualifications are not high, after years of hard study, his mastery of welding materials and techniques has reached an expert level, and he has become one of the rare senior technicians in Fengyang Shipyard.
In particular, Zhao Jingfu has a unique skill, which is the welding technology of ultra-thick steel plates. This is something he figured out based on many years of experience of veteran shipyard workers and his own understanding. It can not only ensure the welding strength but also increase the welding speed. You need to know
On-site welding of ultra-thick steel plates has always been a difficulty in the field of welding, especially placing great demands on the quality and physical strength of workers.
More than 10% of the steel plates used by the Blue Whale this time are ultra-thick steel plates. For Zhao Jingfu, being familiar with the organizational form of the steel plates in advance will help him to control problems that may arise during the welding process, and he can also make adjustments in the future.
To improve the welding performance, timely adjust the composition design of offshore steel to enhance the body and welding strength of offshore steel.
Discussions between Fuhai Group and Hong'an Steel on the research and development of F-class ultra-high-strength marine engineering steel are in full swing at the Materials Research Institute of Hong'an Steel.
Zhang Yujie submitted the basic stress analysis drawings of the Blue Whale to Han Fangyun, pointing out that the F-class ultra-high-strength marine steel developed this time is used in the main stress-bearing parts of the Blue Whale's columns and upper platform, and has withstood huge loads.
pressure.
According to various requirements such as fatigue and structure, F-class ultra-high-strength marine steel needs to be at least 690MPa or above, and must have excellent low-temperature toughness, welding performance and corrosion cracking resistance, and the thickness specification needs to be 100mm.
This product is named f690 ultra-thick marine board.
Han Fangyun looked at the detailed force analysis table in her hand, and she understood that the research and development task she would take on this time would be one of her biggest challenges since she started working in the metallurgical industry.
"General Manager Zhang, you can rest assured that we at Hong'an Steel will go all out, carry out research and development work day and night, and come up with qualified products within the specified time limit!"
Han Fangyun's reassurance did not make Zhang Yunjie feel at ease. He knew that before the steel plate appeared in front of him, all the guarantees and promises were empty words, but Hong'an Steel's attitude still made him very happy. After all, in such a short period of time,
It is not an easy task to complete the research and development of a high-tech product within a time limit.
"Okay, thank you Director Han for your hard work. This is Comrade Zhao Jingfu, a senior technician from our Fuhai Group. He is our expert in welding. Although his knowledge of materials is not comparable to that of colleagues from Hong'an Steel, but
He is responsible for the welding of this offshore project, so I ask Director Han to seriously consider his ideas and opinions!"
Zhang Yujie knows that he does not have to worry about the quality of materials. Hong'an Steel itself is a special steel production base, and the quality is absolutely guaranteed. What needs to be considered now is the welding problem in the future. After all, the F-class ultra-high-strength marine engineering developed this time
Steel, not only has the extremely high strength of the steel plate itself, but also has another characteristic, which is its ultra-thickness.
Ultra-thick steel plates exceeding 100 mm itself are a test of welding ability. In the past, they would try their best to weld whatever materials the other party provided. This time, if they participated in the welding work in advance during the research and development process, they would be able to make timely adjustments.
The alloy composition of the material will be a great help to enhance the final welding effect, and will also be a great improvement for future welding work.
Zhao Jingfu was listening carefully to both parties' understanding and analysis of the materials. When he saw Zhang Yujie mentioning himself, he stood up hurriedly.
"All of you here are experienced teachers, and I am a young student. I would like to ask for your guidance in future cooperation, and together we can make this series of marine panels world-class!"
"Yes, what we want to do must be first-class! I very much agree with Master Zhao's idea!" Han Fangyun immediately expressed his position, "When we develop materials, we need the participation of practical operators like Master Zhao to enable us to improve the material properties.
, to better serve everyone!”
In a pleasant atmosphere, both parties reached an agreement that they would do their best to complete this material development task within the time frame and meet the needs of the Blue Whale.
After the discussion, Zhang Yujie evacuated with the people of Fuhai Group, leaving only Zhao Jingfu at Hong'an Steel to assist in the development of F-class ultra-high-strength marine panels.
Before leaving, Wei Yuhui selected some reference books that Zhao Jingfu could use and left them to him.
"Take care of your health!" Wei Yuhui said with a smile, "If you have capital, don't abuse it!"
Zhao Jingfu smiled and made a biceps gesture at her, which made Wei Yuhui giggle for a long time.
Seeing the Fuhai Group's team leaving, Zhao Jingfu felt a little sad and more lonely. Fortunately, Hong'an Iron and Steel also knew about this situation and provided him with more convenient living conditions.
Zhao Jingfu also knew that he did not stay in Hong'an Steel to enjoy the blessings. If he did not complete the research and development of F-class ultra-high-strength marine panels within the specified time limit, he might become the sinner of Fuhai Group.
"Director Han, I plan to move to your Iron and Steel Research Institute to facilitate communication. What do you think?" Zhao Jingfu immediately found Han Fangyun.
Han Fangyun looked at Zhao Jingfu with some surprise. In her mind, this young man from the coastal area would definitely dislike the environment of Hong'an Steel, so she arranged for him to stay in the hotel of Hong'an Steel.
Although he is here to help, most of the technical points are listed in the meeting minutes. As long as there are no problems in the general direction, basically just look at the test records every day. This kind of day is not considered
Wronged.
He didn't expect that Zhao Jingfu would actually ask to live in the Iron and Steel Research Institute. No matter how good the treatment there was, it would definitely not be as cool as life in a hotel!
"Director Han, the time given by the company is tight, so I have to pay attention. After all, the Whale Dream Project embodies the desire of all Fuhai people for the future and the will of independent innovation. If something unexpected happens, I really
I can’t explain it!”
Han Fangyun understands what Zhao Jingfu is thinking, and she also knows the importance of offshore engineering boards to the Blue Whale. This can be seen from the fact that Zhang Yujie personally led the team.
"You can come to the institute, but the hardware facilities here may not be as good as a hotel. You have to bear with that!" Han Fangyun said with a smile.
Zhao Jingfu looked unconcerned, "What's the point? When I was in the shipyard, I had a welding task. I stayed on site all day and night, and even just lay down in the steel pipe to take a rest. There is always a place at the research institute.
