Chapter 133 Experimental test, Helen’s application and Wuhan Iron and Steel’s decision
Determine
For the Wuhan Iron and Steel Research Institute, before conducting experimental tests on magnetic field control, we must first pay attention to the ongoing experiments.
This experiment is based on the data provided by the Alloy Laboratory of Donggang University. The process and details of the entire manufacturing process are slightly modified, and simulation and actual operation are carried out simultaneously to achieve the prediction and evaluation of the revised results.
The conclusion of the final estimate and evaluation is still improved compared to before.
Ding Zongquan talked about a lot of data and finally concluded, "Based on this result, if it enters the production line, the defective rate will be reduced by 0.8% to 1.76%."
Others also discussed it.
The latest data method provided by the Alloy Materials Laboratory of Donggang University has once again reduced the defective rate of ultra-thin steel produced based on double-roller casting and rolling technology.
This is definitely an improvement, but it's just expected.
A joint project between the Wuhan Iron and Steel Research Institute and the Alloy Materials Laboratory of Donggang University aims to reduce the defective rate by more than half.
The reduction in data from one experiment was less than 2%, which can be said to be very small progress. Since the beginning of the cooperation project, the defective rate has been reduced by about 8% compared to the beginning.
The data is quite impressive, but more than one-third of the funds have been spent. It can be said that it has not met expectations at all, and is even far behind.
This situation is also within the normal range.
In the field of materials research, it is very normal for a certain R&D project to fail to meet expectations, especially in R&D for technological improvement. It is normal for tens of millions of investments to go to waste without any results.
Looking at the data on the defective rate, we can know that the Alloy Laboratory of Donggang University is indeed working on the project seriously.
For ultra-thin steel produced by twin-roll casting and rolling technology, the most common defective rate is steel cracks. Defective products caused by steel cracks account for more than 90% of all defective products.
As long as the problem of steel cracks is solved, everything else can be said to be a minor problem.
After the day's experimental summary meeting, Wang Jiming announced that he would conduct research on the "effect of magnetic field stability on steel cracks in double-roller casting and rolling technology."
This research is not exploratory, it is just an experiment for testing.
The project progress of the Alloy Laboratory of Donggang University did not meet expectations, which made Wang Jiming want to try. Only by finding the root cause of steel cracks can we solve this problem. Otherwise, if we do research and development bit by bit, even if most of the problems are solved,
The problem, in the end, I don’t know where the problem lies.
Although testing and research will consume a lot of money, if the root cause can be found, everything will be worth it.
This experimental test is not conducted once or twice, but to manufacture products under various magnetic field environments and study the probability of steel cracks in the products.
If you still need to conduct testing later, you may even have to try it on the factory's production line.
Experimental testing is not straightforward.
The magnetic field control equipment on Wuhan Iron and Steel's twin-roller casting and rolling technology production line is provided by foreign companies and is an integral magnetic pole electromagnetic side sealing device.
It was initially known that there were some problems with this device.
The biggest problem is that the electromagnetic induction intensity is too large, the bottom of the magnetic pole is seriously heated, and the magnetic field distribution is uneven at the same molten pool depth.
This is also the reason why Zhang Gong concluded that steel cracks are related to magnetic field control.
If they want to conduct experimental tests, they need to find a stable magnetic pole control device. For ordinary laboratories, this is a requirement that is simply impossible to achieve. However, for the Wuhan Iron and Steel Research Institute, it has sufficient R&D funds and strength.
A strong R&D partner is nothing at all.
The next morning, Wang Jiming contacted the Institute of High Magnetic Field Physics, who said they could provide equipment support and even technical support.
Of course, the premise is that the funds are in place.
After spending an exciting amount of money, all the equipment and personnel were quickly put in place. Two sets of equipment were even shipped directly. There were dedicated personnel to install it in the operation room. They were also prepared to participate in the experimental test. The service can be said to be absolutely
It's first class.
Under the coordination of Wang Jiming, the entire Wuhan Iron and Steel Research Institute made way for the study of "the impact of magnetic field stability on steel cracks in twin-roll casting and rolling technology."
On the third day, the experimental test officially began.
at the same time.
In the Alloy Materials Laboratory of Donggang University, Chen Jianlin received the experimental report from the Wuhan Iron and Steel Research Institute. Looking at the data on the ‘defective rate reduction value’, he still felt a little dissatisfied.
This research is something Chen Jianlin attaches great importance to.
The Alloy Laboratory sometimes applies for funds with false data, but some projects are also done with care. The horizontal project of the Wuhan Iron and Steel Research Institute is a project that they attach great importance to.
Chen Jianlin's personal level is still relatively high.
Both Donggang University and the domestic materials research and development circle have high evaluations of his abilities.
Chen Jianlin is now dissatisfied with the progress of this project. He doesn't understand why he is working on the project normally and working very hard but the progress is very slow.
The data submitted this time was originally expected to reduce the defective rate by more than 10%, but the result was only an improvement of less than 2%. The value is really too different.
Chen Jianlin frowned and held a meeting with the project team. Then he found Ma Wenjun alone and discussed the issue of data analysis.
Ma Wenjun is an expert in material calculations, and we still need to rely on him to advance the project.
But when he discovered that the progress of the project was very small, Chen Jianlin immediately cast his doubtful eyes on Ma Wenjun.
Is it because Ma Wenjun didn't contribute?
Did he deliberately not do it carefully, or did he have other considerations?
Chen Jianlin was always a suspicious person. He never trusted Ma Wenjun very much, and the only person he trusted, Zhou Xiaolong, had left, and now he was thinking more.
Of course.
Chen Jianlin would definitely not show it. As usual, he explained that the experiment did not meet expectations, and then said encouragingly, "Although it did not meet expectations, alloy research is often like this."
"Sometimes, for a project with perfect technology, there will be no progress after a year of research, otherwise Wuhan Iron and Steel would not find other institutions to jointly develop it."
"Fortunately, Wuhan Iron and Steel still trusts us. I have confirmed with Ding Zongquan that new funds will come in half a month. At that time, we can conduct another large-scale experiment. I hope this time we can achieve the expected results.
Target."
"Professor Ma, I still have to rely on you. You should work harder."
Ma Wenjun adjusted his glasses and said with a smile, "Don't worry, this is my job."
Ma Wenjun and Chen Jianlin talked for a few words and then left.
He knew very well that Chen Jianlin did not trust him, otherwise he would not come to talk to him specifically, but he would do his best in the research after the year and hoped to do a good job in the research.
As long as the project progresses smoothly, he will be able to more safely immigrate to live abroad. He also wants to make another fortune before leaving.
Unfortunately……
Chen Jianlin didn't know what was going on, but he suddenly devoted himself to the project, even forgetting to eat and sleep when starting research and development. He really devoted himself to the front line, which also led to the enthusiasm of the entire laboratory.
Is this still Chen Jianlin?
Ma Wenjun was a little confused, but he subconsciously sensed something was wrong.
…
Wang Hao has returned to Xihai University.
He did not start any new research, but was ready to rest for a while.
Even though I got a new ability, I didn’t want to use it to do any research, mainly because I was too tired some time ago, including the proof of Kakutani conjecture, the summary of S-level difficulty mathematical methods, and the study of aviation.
The Institute of Materials Science conducted a lecture on general analysis methods for beta alloys.
As for the visit to the Wuhan Iron and Steel Research Institute, I suggested that they study and improve the double-roller casting and rolling technology in the direction of "magnetic field control" to increase the yield of ultra-thin steel products. This is what I said when I was experimenting with capabilities at that time.
He didn't take it to heart at all.
Wang Hao decided to rest peacefully and just attend classes as usual, exercise at other times, and occasionally read a book when he was in the mood.
This kind of life is indeed very comfortable, but as an associate professor in a university, things will always come to you.
Ying Changyuan, Director of the Graduate School Admissions Office.
He is responsible for graduate student admissions, and the past month or so can be said to be the busiest time of the year.
For ordinary things, Ying Changyuan would definitely not come to Wang Hao. Even if Wang Hao applied for two majors and six graduate students, he would only go through the normal process and let the graduate students who passed the exam take the re-examination.
This time it's a little different.
Ying Changyuan came over with a graduate student application document.
Many foreign universities have an "application system" for graduate students, and domestic graduate students also have an application system for recruiting international students.
If it were an ordinary international student who wanted to apply for Wang Hao's graduate studies, the graduate school would have to carefully examine him before deciding to recommend him to Wang Hao.
This application is very unusual, and the content in the application materials is astonishing——
Name: Helen Hinton.
Age: 15 years and 10 months.
Passport: Amerikan.
Undergraduate school: Stanford University, with double bachelor's degrees in mathematics and biological sciences.
When he saw this application material, Ying Changyuan felt a little confused. The foreign students who applied for Xihai University were generally the kind of graduates who had "never heard of the institution at all", which can be understood as a "community college".
To put it bluntly, it is called "Wild Chicken University". It can only be found on the Internet and barely meets the standards of a recognized university.
This application came from a student at Amerikan Ivy League University, which can be said to be the first time in the history of Xihai University.
Not only Sokai University, but also Suimu University and Capital University, it is difficult to attract students from Amerikan Ivy League universities to study for graduate school.
If we go back twenty years, master's degrees from domestic universities will not be recognized abroad.
In addition, the surprising thing is not just the school where he graduated. The applicant is obviously a super genius. He got a double major in mathematics and biological sciences at the age of sixteen, which is simply unimaginable.
"She should be here for you." Ying Changyuan hit the nail on the head, but he understood that she was here for Wang Hao's fame.
Wang Hao's understanding was that he came because of his innocence.
His face turned dark when he saw Helen's application materials. The encounter at the Zhucheng Computer Conference was still deeply impressive to this day.
That girl is not yet sixteen years old, but what she is thinking about is the combination of excellent genes to create excellent offspring?
What is this?
Wang Hao hesitated for a moment. He wanted to reject the application directly. But considering that people followed the normal process, it seemed a bit unreasonable to refuse directly. You can't refuse because you don't want to get along with her, right?
In addition, I have to admit that Helen is indeed a genius.
"It's not bad to have a genius under me. Maybe it can be helpful in research?" Wang Hao thought about it and became interested, but couldn't find a reason to reject it directly.
never mind!
"If she wants to come, let her come!" Wang Hao said to Changyuan.
Ying Changyuan took a long breath. Admissions will naturally hope for higher quality students. It would be a pity to miss a super genius from an Ivy League university.
One week later.
The experimental tests at the Wuhan Iron and Steel Research Institute have just been completed. It took much longer than they planned, and even cost several times more money than expected. In order to do the final inspection, they even used the factory production line for a day.
The final results show that the occurrence of steel cracks is directly related to magnetic field control.
After completing the experimental tests, the Wuhan Iron and Steel Research Institute held a core meeting, with participants including researchers from the institute, administrative staff, two managers from the Wuhan Iron and Steel Group, and a vice president in charge of technology.
Wang Jiming took the experimental report and said, "This is our conclusion!"
"The main reason for steel cracks in ultra-thin steel on the twin-roll casting and rolling production line is unstable magnetic field control."
"That's what Professor Wang Hao from Xihai University said. He also mentioned the temperature field problem. We haven't done any specific tests yet, but the magnetic field control has been proven, so the temperature field should be no problem."
"So the relevant research direction should be to develop stable magnetic field devices and temperature field devices, rather than improving technology and processes."
"We are looking in the wrong direction, so it is no wonder that the relevant research progress is very small."
"So, in order to reduce losses, I suggest that the first step is to stop all related projects, including cooperation projects with other institutions."
