Early the next morning, Zhao Jingfu came to the F690 low-temperature CTOD test site located in Fengyang Shipyard and contacted Hong'an Steel about the possibilities he had thought of last night.
Han Fangyun was also very surprised when she heard what Zhao Jingfu said. After all, this kind of thing is very rare, especially when the solder has reached the stress level, and the pores appeared again, this is obviously a major problem.
Zhao Jingfu told Han Fangyun the results of his experiments during this period, and then asked her for advice on possible problems.
"Director Han, I also feel very strange. Logically speaking, this phenomenon should be related to current and voltage, but we really don't have time to try and make mistakes like this. You are an expert in materials. Is there any other good way to solve it?
What about this matter?" Zhao Jingfu heard Han Fang and Han Fang on the other end of the phone seem hesitant.
He immediately said: "Director Han, F690 is the first ultra-high-strength marine steel plate in China. If there are always problems with welding, it will be a blow to F690. If you help solve this problem, it may also be F690 in the future.
A brand new way out.”
Zhao Jingfu's words made Han Fangyun a little undecided. She knew that Zhao Jingfu's words made sense. Although F690 was the latest development of Hong'an Steel, it was unknown in terms of quality and other aspects. The problems that occurred in Fuhai Group this time were just like Zhao Jingfu's.
As mentioned, once it becomes a common problem with f690, it will cause great difficulties for Hong'an Steel's future sales and recommendations.
Even if it is not for Fuhai Group, it must be done for Hong'an Steel and the brand new F690.
Han Fangyun thought about it for a while on the other end of the phone, and then said with some doubts: "Master Zhao, the situation you mentioned is indeed a problem for us. If you are relieved, I can ask Hong'an Steel to do a series of
Testing, after all, the scientific research conditions here are better!"
What Zhao Jingfu was waiting for was Han Fangyun's words.
Although Fuhai Group also has a strong materials research department, after all, they are only an application department. Compared with research departments such as Hong'an Steel, it is still far behind. Moreover, the f690 was developed by a scientific research team led by Han Fangyun.
Naturally, the physical and chemical properties are well understood.
After receiving Han Fangyun's affirmative answer, Zhao Jingfu breathed a sigh of relief, but he also knew that there were some things that he couldn't pin his hopes on others, and he also needed to work harder.
Zhao Jingfu immediately took out the test records of the recent period and began to conduct a series of analyzes based on these experimental data to see if he could find some clues.
Just as he was watching, a sound of parking came from outside the testing site.
Zhao Jingfu didn't even raise his head, but he was thinking in his heart, why did Wei Yuhui come so early today? Didn't he tell her that he would contact Hong'an Steel in the morning and not conduct experiments for the time being?
Following the sound of footsteps as he stepped into the testing site, Zhao Jingfu was still immersed in searching for data, and then said: "Wei Da Inspection, why are you here so early today? I guess there won't be any materials for you to test in the morning!"
"Why not?" Zhang Yujie asked.
After Zhao Jingfu heard the sound, he suddenly looked up and found that the person who walked into the test site was not Wei Yuhui, but Zhang Yujie, the chief engineer of Fuhai Group.
"General Manager Zhang, why are you here?" Zhao Jingfu hurriedly got up, and in his panic, he even knocked over the chair under his buttocks, making a dull sound.
Zhao Jingfu looked back at the chair with some embarrassment, and then hurriedly came out to greet Zhang Yujie.
"Let me take a look at the low-temperature CTOD experiment of F690!" Zhang Yujie looked at the remains of various welding materials everywhere in the test site, which looked like an abandoned warehouse.
"It's not ideal!" Zhao Jingfu didn't hide anything. "We found welding materials and processes that can achieve the stress, but problems occurred. After welding, pores appeared in the steel plate, which has great hidden dangers for future strength."
"I saw the situation you reported, and I would like to ask if there is any progress now?"
Zhao Jingfu shook his head slightly, "There is still no further progress. I have just contacted Hong'an Steel. Director Han has agreed to provide technical support and conduct a series of tests to see what happened.
question!"
"What is the possible reason for the recognition of Hong'an Steel?" Zhang Yujie asked.
"I don't know. Director Han said that this phenomenon is extremely rare because f690 and welding materials are new materials. No one can tell what will happen at high temperatures!"
"What about current, voltage and temperature? Are there any new discoveries?"
Zhao Jingfu still shook his head. He pointed at the scraps and wreckage in the test site and said: "No, the experimental team has used many methods to test current and voltage in various aspects. It has been done thousands of times, and it is still
Didn't find the problem!"
"We must hurry up. Zhang Dadong came back yesterday. He brought a huge challenge to our Whale Dream Project!"
When Zhao Jingfu heard this, he couldn't help but feel a thump in his heart. Zhang Dadong was back, so this matter was absolutely necessary. And seeing that Zhang Yujie came in person to ask about the low-temperature CTOD experiment, it was obviously related to F690.
"General Manager Zhang, what is the challenge?" Zhao Jingfu asked quickly.
"Zhang Dadong brought the requirements from the relevant higher-level departments, and the Blue Whale needs to complete the main engine load test within one and a half years!"
"What, how is this possible?" Zhao Jingfu's reaction was basically the same as everyone else's, "Just the welding task of the Blue Whale is not enough even if everyone at Fengyang Shipyard is involved!"
"You have the same idea as us!" Zhang Yujie said with a smile, "Fortunately, there is a new method now. We plan to build the Blue Whale branch factory in three parts. In this way, the three shipyards can start construction at the same time.
The construction period can be significantly reduced, but the problem is..."
When Zhao Jingfu saw Zhang Yujie looking at him, he immediately understood what the problem was.
Low temperature CTOD experiment!
F690 is the basis of the Blue Whale. If its welding test is not completed, it will definitely not be possible to start construction.
This means that the entire Blue Whale construction period will be delayed.
Zhao Jingfu did not expect that the future of the Blue Whale would be so closely related to him, and that the burden on his shoulders would be so heavy.
"General Manager Zhang, I..."
"I know what you are thinking, so we have to find a way together. We must completely solve the low-temperature CTOD experiment before the Blue Whale starts construction, so that F690 can become the solid skeleton of the Blue Whale!" Zhang Yujie patted Zhao Jingfu on the shoulder and said.
