For WISCO Research Institute, before doing the experimental test of magnetic field control, we should first pay attention to the ongoing experiments.

Based on the data provided by the Alloy Laboratory of Donggang University, the process and details of the entire manufacturing process were modified slightly, and the simulation and practical operation were used simultaneously to estimate and evaluate the corrected results.

The conclusion of the final estimated evaluation is still improved compared to before.

Ding Zongquan said a lot of data, and finally concluded, "According to this result, if you enter the production line, the defective rate will be reduced by 0.8%~1.76%. ”

Others also discussed.

The latest data method provided by the Alloy Materials Laboratory of Donggang University has led to a further decrease in the defective rate of ultra-thin steel produced based on the double-roll casting and rolling technology.

It's definitely an uplift, but it's expected.

The project cooperated by 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 the data of the first experiment is less than 2%, which can be said to be very small, and since the beginning of the cooperative project, the defective rate has been reduced by about 8% compared with the beginning.

The data is quite impressive, but it has already cost more than one-third of the money, which can be said to have completely failed to meet expectations, and even a little far behind.

This 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 the research and development of technological improvement.

If you look at the data of the defective rate, you can know that the alloy laboratory of Donggang University is indeed seriously working on the project.

The most defective rate of ultra-thin steel produced by double-roll casting and rolling technology is the occurrence of steel cracks, and the 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 end of the day's experimental summary meeting, Wang Jiming announced that he would conduct a study on the influence of magnetic field stability of double-roll casting and rolling technology on steel cracks.

This research is not exploratory, it is just an experiment to test.

The project progress of the alloy laboratory of Donggang University did not meet expectations, so Wang Jiming wanted to try, and only by finding the root cause of steel cracks could he solve this problem, otherwise he would do research and development little by little, even if most of the problems were solved, in the end, he would not know where the problem was.

Testing can be expensive, but it's worth it if you can find the root cause.

This experimental test is not carried out once or twice, but to manufacture the product in various magnetic field environments, and to study the probability of steel cracks in the product.

If you want to test it in the future, you even have to try it on the production line of the factory.

Experimental testing is not straightforward.

The magnetic field control equipment on the production line of Wuhan Iron and Steel's double-roll casting and rolling technology is provided by foreign companies, which is an integral magnetic pole electromagnetic side sealing device.

It was known from the outset that there were some problems with such a device.

The biggest problem is that the electromagnetic induction intensity is too large, and the bottom of the magnetic pole is seriously heated, and the magnetic field is unevenly distributed at the depth of the same molten pool.

This is also the reason why Zhang Gong judged 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, which is a requirement that cannot be done at all for ordinary laboratories, but for Wuhan Iron and Steel Research Institute, it is nothing to have sufficient R&D funds and strong R&D partners.

The next morning, Wang Jiming contacted the Institute of Strong Magnetic Field Physics, and the other party said that he could provide equipment support and even technical support.

Provided, of course, that the funds are in place.

After spending enough money to make people excited, the equipment and personnel were all in place quickly, and even two sets of equipment were shipped directly, and there were special personnel to install them in the operation room, and they were ready to participate in the experimental tests, and the service can be said to be absolutely first-class.

Under the coordination of Wang Jiming, the Wuhan Iron and Steel Research Institute made way for the study of "the influence of magnetic field stability of double-roll casting and rolling technology on steel cracks".

On the third day, the experimental test officially began.

Meanwhile.

In the Alloy Materials Laboratory of Donggang University, Chen Jianlin received the experimental report from the Wuhan Iron and Steel Research Institute, and looked at the data of the 'defective rate reduction value' on it, and still felt a little dissatisfied.

Chen Jianlin attaches great importance to this research.

The alloy laboratory has false data to apply for funding, but some projects are also done with heart, and 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.

Whether it is Donggang University or the domestic material research and development circle, he has a high evaluation of his ability.

Now the progress of this project makes Chen Jianlin dissatisfied, he doesn't understand why he is doing the project normally, and he works hard to research the progress is very slow.

The data submitted this time was expected to reduce the defective rate by more than 10%, but the result was an increase of less than 2%, which is too much difference.

Chen Jianlin frowned, held a meeting with the project team, and then found Ma Wenjun alone and talked about data analysis.

Ma Wenjun is an expert in material calculation, and the project still depends on him.

But when he found that the progress of the project was very small, Chen Jianlin immediately put his suspicious eyes on Ma Wenjun.

Is it that Ma Wenjun didn't contribute?

Did he deliberately ignore it, or did he have other considerations?

Chen Jianlin was originally a suspicious person, he has never trusted Ma Wenjun very much, and Zhou Xiaolong, the only trusted person, has left, and now he thinks more.

Of course.

Chen Jianlin will definitely not show it, he still explained as usual, that the experiment did not meet expectations, and then said encouragingly, "Although it did not meet expectations, alloy research, many times like this." ”

"This kind of technically perfect project, sometimes, there is no progress in research for one or two years, otherwise WISCO will not find other institutions to jointly develop it."

"Fortunately, Wuhan Iron and Steel still trusts us, I have already confirmed with Ding Zongquan, new funds will come in half a month, and when the time comes, we will be able to conduct another large-scale experiment, I hope that this time we can achieve the expected goal."

"Professor Ma, I still have to rely on you, you work harder."

Ma Wenjun helped his glasses and said with a smile, "Don't worry, this is my job." ”

Ma Wenjun and Chen Jianlin talked a few words and left.

He knew very well that Chen Jianlin didn't trust him, otherwise he wouldn't have come to talk to him in particular, but he did his best to do his research in the future, and he also hoped to do a good job in research.

As long as the project goes well, he will be able to move to live abroad more steadily, and he wants to make another profit before leaving.

It's a pity......

Chen Jianlin didn't know what was going on, so he suddenly devoted himself to the project, and even forgot to sleep and eat when he started research and development, and really put himself on the front line, which also drove the entire laboratory to be active.

Is this still Chen Jianlin?

Ma Wenjun was a little confused, but he subconsciously sensed that something was wrong.

……

Wang Hao has returned to Xihai University.

He didn't start any new research, but was ready to rest for a while.

Even if I got a new ability, I didn't want to use my ability to do any research, mainly because I was too tired some time ago, including the proof of Kakutani's conjecture, including the summary of S-level difficulty mathematical methods, and also going to the Institute of Aeronautical Materials to give a lecture on general analysis methods for β alloys.

As for visiting the Wuhan Iron and Steel Research Institute, by the way, it was suggested that they should study and improve the double-roll casting and rolling technology in the direction of 'magnetic field control' to increase the yield of ultra-thin steel, which was what I said during the experimental ability at that time.

He didn't take it to heart at all.

Wang Hao decided to rest with peace of mind, but he usually went to class normally, and the rest of the time was to exercise, and occasionally read a book when he was in the mood.

It's a comfortable life, but as an associate professor at a university, there's always something to come to your door.

Ying Changyuan, Director of Admissions at the Graduate School.

He is in charge of graduate admissions, and the last month or so can be arguably the busiest time of the year.

For general things, Ying Changyuan will definitely not come to Wang Hao, even if Wang Hao applies for two majors and six graduate students, he will only go through the normal process, and let the graduate students who have passed the exam participate in the re-examination.

This time it's a little different.

Ying Changyuan came to him with a graduate application document.

Many graduate students in foreign universities are 'application system', and domestic graduate students are also application system for international students.

In other words, if you want to apply for Wang Hao's graduate school, the graduate school will carefully investigate it before deciding to recommend it to Wang Hao.

This application is very unusual, and the content on the application materials is very amazing-

Name: Helen Hinton.

Age: 15 years and 10 months.

Passport: Ameriken.

Graduated from: Stanford University, with a double bachelor's degree in mathematics and biological sciences.

When he saw this application material, Ying Changyuan felt a little confused, foreign students who apply for Xihai University are generally graduates who have never heard of colleges and universities, which can almost be understood as "community colleges", and "pheasant universities" to say that they are ugly, but they can be found on the Internet, and they barely meet the standards of recognized universities.

The application came from an Ameriken Ivy League student, the first in the history of Westsea University.

Not only Seohai University, but also Mizuki University and Metropolitan University, it is also difficult to attract students from Amriken Ivy League University to study in graduate school.

If you go back 20 years, the master's degree of domestic universities will not be recognized abroad.

In addition, it is surprising that it is not only the graduate school, the applicant is obviously a super genius, and it is unthinkable to get a double degree in mathematics and biological sciences at the age of sixteen.

"She's supposed to be here for you." Ying Changyuan said it, but he understood that he came for Wang Hao's fame.

Wang Hao's understanding is that he came for his innocence.

He saw Helen's application materials, his face was a little dark, and the encounter at the Zhucheng Computer Conference was still impressive.

That girl is not yet sixteen years old, and what she thinks in her mind is that excellent genes combine to create excellent offspring?

What is this?

Wang Hao hesitated suddenly, he wanted to reject the application directly, and then think about the normal process, it seems a bit unreasonable to refuse directly, you can't say that you don't want to get along with her?

In addition, I have to admit that Helen is indeed a genius.

"There's a genius under him, and it's not bad. Maybe it can be helpful for research? Wang Hao thought about it, and he was a little interested, but he couldn't find a direct reason to refuse.

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 a higher quality of students, and it would be a pity to miss a super genius from an Ivy League university.

A week later.

The experimental tests of the Wuhan Iron and Steel Research Institute were all over, and it took much longer than they planned, and even the funds they spent were several times more than expected, and they even used a day's factory production line for the final inspection.

The final results show that the occurrence of steel cracks is directly related to the magnetic field control.

After the completion of the experimental tests, the WISCO Institute held a core meeting with the participation of the institute's researchers, administrative staff, two managers of the WISCO Group, and a vice president in charge of technology.

Wang Jiming took the experiment report and said, "This is our conclusion!" ”

"The main reason for the occurrence of steel cracks in the ultra-thin steel on the double-roll casting and rolling production line is the unstable magnetic field control."

"Professor Wang Hao of Xihai University said so, he also mentioned the problem of temperature field, we have not done specific tests, but the magnetic field control has been proven, then the temperature field should be no problem."

"Therefore, the relevant research direction should be to develop stable magnetic field devices and temperature field devices, rather than to make technical and process improvements."

"We're looking in the wrong direction, and it's no wonder that the progress of the research is so small."

"So, in order to reduce the damage, I recommend that the first step is to stop all related projects, including those with other organizations."

"Let's vote!"

"Agreed!"

"Agreed!"
