In the small white building, Zhang Yujie, who had just gone to work, had not even sat down when the phone in front of him rang.
He lowered his head and saw that it was Hu Yufeng from Fengyang Shipyard calling.
All conditions for the construction of the Blue Whale are mature, and all project plans are proceeding in an orderly manner. Although Fuhai Group has the strongest construction capabilities, Fengyang Shipyard still has not started construction of the Blue Whale. The reason is that the F690
The stomata problem has not been solved.
"I'm Zhang Yujie!" He immediately picked up the phone.
"General Manager Zhang, let me tell you good news!" Hu Yufeng couldn't hold back his excited tone on the phone. "After testing day and night, Zhao Jingfu led the research team to successfully find the most appropriate welding process. The welding technology currently obtained
The results have initially passed the test, and Fengyang Shipyard is undergoing the second round of repeated tests. If it passes, we can conduct low-temperature CTOD experiments!"
"Is the stoma problem solved?" Zhang Yujie stood up immediately upon hearing this.
"Yes! It has been solved. We are retesting it. The problem should not be big!"
Another key point of the Whale Dream project has been overcome, which is the final obstacle to the construction of the Blue Whale.
"Okay, I will immediately lead the technical department of the group company to Fengyang Shipyard to complete the low-temperature CTOD experiment as soon as possible!" Zhang Yujie knew the importance of the experiment and decided to lead the team in person.
For a time, Fengyang Shipyard was crowded with people, and vehicles from the shipyard and group companies were parked in the open space outside the test site. Zhang Yujie led a dozen engineers to carefully conduct all-round inspections of the steel plates welded by Zhao Jingfu's research team.
The final result was that it fully met the stress strength requirements, which was consistent with the previous preliminary inspection results. The pores that originally troubled them did not appear, and all other testing items met the requirements.
"Carry out the low-temperature CTOD experiment immediately!" Zhang Yujie issued this order on the spot.
The frozen f690 experimental module was taken out of the insulating box and placed in the low-temperature experimental tank to start the load fatigue test.
This is the first time in the world that a low-temperature CTOD experiment has been carried out on the 100 mm thick F690. Although the F690 can theoretically complete it, no one dares to say whether there will be any accidents.
Various previous accidents have made everyone on tenterhooks. This time everyone looked very solemn, quietly waiting for the final result to appear.
Zhao Jingfu is the most nervous one among the crowd. From the development of F690 to the welding experiment, he has watched F690 move forward little by little towards the foundation of Blue Whale. Now it has reached the most critical step. As long as the low-temperature CTOD experiment is successful, then
f690 can become the strongest guarantee for Blue Whale.
Wei Yuhui, who was standing next to him, was also nervous, staring at the various data changes on the instrument for fear of an unexpected signal appearing.
There was total silence in the entire laboratory. Apart from the roar of the testing instruments, the only sound was everyone's breathing.
Hong'an Steel's three months of full-load development and Zhao Jingfu's test team's welding experiments day and night are all for the F690 to become a part of the Blue Whale. Only by passing the low-temperature CTOD test can this plan be realized.
The f690, which has gone through countless hardships, will face the final test!
Since the low-temperature CTOD experiment is related to the strength change of the Blue Whale under harsh conditions, Fuhai Group regards it as the strongest guarantee for the safety of the Blue Whale. Only through rigorous experiments can we have the strongest Blue Whale.
The wait is always long, and just a few hours makes everyone anxious.
"General Manager Zhang, this is our final experimental result!"
Finally, engineers from the group company's technical department submitted the final experimental results to Zhang Yujie.
Zhang Yujie calmly took over this trial document, which is almost a trial of the f690 welding process. Whether it is a success or a failure depends on the final data!
Zhao Jingfu couldn't help but grab Wei Yuhui's hand beside him. Wei Yuhui was stunned for a moment, and then gently patted the back of Zhao Jingfu's hand to soothe his overwhelmed heart.
All eyes were focused on this piece of paper, which held countless hopes. In the spotlight, Zhang Yujie read every line of words on it.
Even though he has developed a stable character over the years, Zhang Yujie still cannot suppress the excitement in his heart.
"The low-temperature CTOD test of 100 mm thick F690 super-strength marine steel plate. All data meet the standard requirements. I declare the test a success!"
Zhang Yujie said this sentence almost word for word. Although it sounded very plain, everyone knew that the chief engineer suppressed his inner excitement and said it!
With thousands of previous various tests as a basis, the low-temperature CTOD experiment of F690 was finally successful.
This is not only the first time for Fuhai Group, but also the first time in China and the first time in the world to conduct such an experiment on a 100 mm super-strength offshore steel plate.
The success of the experiment not only cleared the final obstacle for the construction of the Blue Whale, but also made Fuhai Group the first company capable of conducting such low-temperature CTOD experiments, which is a milestone for the future development of the international market.
"Successful!" The crowd suddenly burst into cheers.
Zhao Jingfu also cheered immediately. Only then did he remember that he was still holding Wei Yuhui's hand tightly. He couldn't help but blush, and he quickly let go.
I don't know who got a few fireworks and set them off directly, which made Hu Yufeng frown. However, during such a festive time, he had no choice but to acquiesce to the happy mood of the workers.
The low-temperature CTOD experiment of F690 was successfully completed, passing the final hurdle of the construction of the Blue Whale.
Later, Zhang Yujie and Hu Yufeng beside him jointly announced that the key parts of the Blue Whale, the pontoons and columns, would officially start construction at Fengyang Shipyard from now on.
The pontoons and columns are the solid foundation of the entire Blue Whale. Whether the platform of tens of thousands of tons can swim in the boundless sea depends on whether the foundation is stable.
Hong'an Steel has already prepared thousands of tons of F690 super-strength marine panels for Fuhai Group. As soon as the low-temperature CTOD test is successful, it will be immediately transported to Fengyang Shipyard to start the basic construction of the Blue Whale.
Vehicles transporting F690 slowly drove into the warehouse of Fengyang Shipyard. These steel plates will become part of the Blue Whale in the near future.
Several shipyards affiliated with the Fuhai Group have cleared the construction slips according to the divisional construction model, all personnel are fully equipped, and all kinds of materials are quickly in place, waiting for the order to start full-scale construction.
