While the young expert was talking, Jin Songyong shook his hand again and again, "No, Xiao Wang, you are wrong...... " As he spoke, he turned his head and said eagerly to Jiang Xinwei, "Mr. Jiang, can you draw a schematic diagram?" I think it is necessary to add this device, maybe it can solve the problem that has been bothering me. ”

Jiang Xinwei already knew from the other party's words that the other party had understood what he meant, after all, this thing was not high-tech, it could only be regarded as a small idea, as long as he pointed out its function and said its name, as an expert, he would definitely be able to understand what this thing was, and even its general shape and related functions had appeared in his mind.

The reason why he asked Jiang Xinwei to draw it was to verify his idea, and second, he didn't want to take the credit of Jiang Xinwei: this device was conceived by Jiang Xinwei, so the credit should be attributed to Jiang Xinwei.

Although he didn't understand how Jiang Xinwei, a corporate executive, would know about the installation of this heat reflector.

Jiang Xinwei admires Jin Songyong's brightness and modesty. He was not too pretentious, and quickly picked up the pen and drew on the handout in his hand.

This thing, the heat reflector, sounds like a hemispherical metal plate, like the double-glazed glass in a thermos flask, which reflects and insulates heat, and the function is to reflect the heat emitted by the monocrystalline furnace, but it can be adjusted by guò to adjust its shape and angle to define the path of heat reflection back.

Jin Songyong's eyes stared at Jiang Xinwei's moving pen, and he was very excited.

Before Jiang Xinwei finished painting, an expert sitting behind him couldn't help but exclaim: "Great! What a stroke of genius, adding such a simple thing will solve several problems that have troubled us." I never thought that if I had thought earlier, the output and quality of monocrystalline silicon in our real room would have reached a new level. ”

His eyes and face were full of chagrin, excitement, surprise and sudden realization, and he said in a gaffe, "Professor Jin, this trip is really worth it." …… With the idea that Mr. Jiang said, our harvest is very huge. ”

The expert surnamed Wang, who had just spoken to ridicule Jiang Xinwei, couldn't help but tilt his head over and asked, "Professor Zhou, what he said is really so powerful?" Reflector...... Reflector...... Isn't this just a hemispherical steel plate?"

"Shut up!" Jin Songyong said to the young expert very dissatisfied, "Xiao Wang, I have warned you many times, we must be cautious in our scientific research, although we cannot trust other people's opinions lightly, but we must not arbitrarily deny other people's opinions and suggestions when there is no factual basis." ”

"I ...... , I'm sorry, Professor Jin, I know......" The expert surnamed Wang said Ai Ai Ai, his face became the color of pig liver. In fact, his main purpose was not to question Jiang Xinwei's things, and he felt that Jiang Xinwei, a layman, was charging power and blaspheming his respected mentor by saying a new thing in public in front of his mentor. In order to maintain the dignity of the teacher, he decided to scold a few words first to let the other party know the severity before speaking.

Jin Songyong didn't blame his disciple anymore, but ordered: "Xiao Wang, you take a good look at this device, and then go to the podium to talk about its benefits." When you finish speaking, please ask Mr. Jiang to comment on whether you are right or not, and what problems still exist. ”

Because this thing really doesn't have much technical content, although its role is huge, so the expert surnamed Wang calmed down, and after carefully looking at it for a while according to Jin Songyong's requirements, he immediately understood its function, and couldn't help admiring Jiang Xinwei in his heart.

After he sincerely apologized to Jiang Xinwei, he walked to the podium, first drew a schematic diagram of the heat reflector with colored chalk on the large picture hanging in front of the blackboard, and then said to all the students who listened to the class: "Just now Mr. Jiang said a good idea, which is to add a hemispherical reflector above the crucible of the single crystal furnace. It's a great idea, why is it so good?......"

Seeing the other party talking eloquently, Jiang Xinwei admired his open-mindedness very much, and said in his heart: "This guy is good, he belongs to a straight character, he will say whatever he wants, and he will correct it immediately if he knows that he is wrong,...... , he is very much to my liking. ”

The reason why Jiang Xinwei said this thing in public just now is of course to give everyone a preventive shot, which is intended to tell them: I, Jiang Xinwei, also understand the technology of monocrystalline furnaces, and also understand the production of monocrystalline silicon, and I also have unique insights.

This is to pave the way for him to "point fingers" and "guide insiders" on high-tech equipment such as monocrystalline furnaces in the future, and with this unexpected gadget with a simple technology but significant effect, when he will say to the section-level personnel in the future what crucible layering, magnetron lifting, and so on have a significant effect on improving the monocrystalline furnace technology, these experts will not be too surprised, and may not be overly curious about his sudden intelligence, cleverness beyond their level and ask the source of these technologies.

He used this heat reflector as a stepping stone today because when this device was invented in his previous life, it was also an inadvertent idea of a non-senior technician, and just adding a reflector above the smelting zone achieved immediate results. Through the wrapping and reflection of the heat reflector, the molten heat of the polycrystalline silicon is bound in the melting area, and the temperature fluctuation on the silicon rod is very small when the monocrystalline silicon is pulled, and the adverse effects caused by the temperature fluctuation are greatly eliminated, which is conducive to improving the purity and quality of the monocrystalline silicon, so that its purity index has been improved by an order of magnitude.

It is such a simple technology, low cost, almost nothing to do with high-tech, but because no one has pierced this piece of paper, so that Chinese scientists have not known that there is this thing, and Western countries have been keeping it secret from our country, and some imported monocrystalline furnaces have also been deliberately removed from this device, which greatly misleads China's monocrystalline silicon manufacturing process, making it difficult to improve the quality and quantity of monocrystalline silicon in China.

Jiang Xinwei knows about this because he communicates with semiconductor companies a lot, and he also knows that Chinese scientists have suffered losses in this little gadget. At that time, an expert said to Jiang Xinwei with a smile: "This small device has no technology at all, just like the mud wrapped around the outside of a chicken." How technical do you say that the action of wrapping the chicken in mud and applying mud is very technical? It is estimated that it is a lazy trick that the beggar came up with to save trouble, but just applying some mud to the chicken, the roasted chicken tastes much more fragrant than ordinary barbecued chicken. We just didn't think about it at the time, and we thought that people were using some kind of high-tech means. ”

Jiang Xinwei couldn't help but say it when he thought of it, regardless of whether the single crystal furnace shipped from Italy this time was installed or not.

If it is installed, it will be good, Jiang Xinwei also saved a lot of tongue, people will think that he knows it from the mouths of Frankl and others, anyway, Frankl, Zeng Hetao and others have now become a trash can for him, once he has something unspeakable, he can push it on them.

If this thing is not installed on the monocrystalline furnace in Italy, it is even better, Jiang Xinwei can design a far better device than the heat reflector installed on the monocrystalline furnace in the world at present, and can introduce the heat reflector of the 21st century in one step, so that Jin Songyong and their manufacturing are not installed in the monocrystalline furnace, if he uses the crucible coating and magnetron lifting technology, maybe China's monocrystalline silicon manufacturing technology and manufacturing capacity will leap to the forefront of the world, and in the future, a large number of monocrystalline silicon or silicon wafers can be exported abroad, and they will not have another cash cow？

Others may not know how big the market for monocrystalline silicon or silicon wafers is, but Jiang Xinwei is absolutely clear, and you can understand it if you think about it: in the 21st century, everyone has a computer, everyone has a mobile phone, every family has a color TV, a smart washing machine, and a refrigerator.

The market for monocrystalline silicon or silicon wafers can be described as completely endless.

At this time, the expert surnamed Wang was telling more and more excitedly: "...... Our single crystal furnaces are all open-mouthed, the heat generated by the bottom melting area is radiated to all directions through the single crystal furnace itself, and the single crystal furnace is surrounded by heat, and the silicon crystal rod is in a continuous heating state, which is difficult to crystallize, thus increasing the difficulty of preparation. At the same time, the crystals on the periphery of the monocrystalline silicon rod crystallize and melt again and again due to repeated lifting, which will inevitably cause the quality of the monocrystalline silicon rod to decrease, and the bubbles and cracks in the outer ring to increase.

In the future, if there is this heat reflector, the situation will immediately become different, and the heat of the monocrystalline furnace will be like a wild horse being reined in, and the growth rate of silicon crystal rods will definitely be effectively improved. Secondly, at the beginning I was confused, all the things that I wanted to veto improved thermal efficiency and reduced power consumption. I don't know exactly how much fuel consumption will be reduced, but I can definitely say that it will reduce electricity by at least 10 percent. This figure is not simple, 10 percent. As we all know, electricity consumption is long-term, if you can save 10% of electricity every day, how much can you save in a month, a year, 10 years. That's an astronomical ......."

Hearing this, Jiang Xinwei smiled inwardly: "Ten percent, you are too conservative." If this heat reflector is well manufactured, it can save at least 20 percent more electricity and half the crystallization time. If modern control technology is used, electricity can be saved by 30 percent or even 35 percent!"

The expert surnamed Wang didn't know Jiang Xinwei's inner thoughts, he continued to happily put up the third finger, and said loudly: "The third benefit is the most useful, because with this heat reflector, the temperature of the lifting zone will be stable, and the single crystal will be more stable and orderly when growing, which can not only provide the yield rate of the monocrystalline silicon rod, but also improve the diameter of the monocrystalline silicon rod." ……”
