Technological power starts with upgrading lenses

When Deputy Mayor Huang first heard the news, he almost thought he had heard it wrong.

"They have only been here for more than a month, and they built a single crystal furnace so quickly?"

"It should have been made, but whether it can successfully produce qualified silicon rods depends on the specific test results. They have now submitted an application for experimental registration to the power supply, fire protection and other departments."

"Then what are you waiting for? Hurry up and get all departments into action and fully cooperate with their experimental tests!"

"Okay, I'll go down and make arrangements right now."

"Well...wait a minute, there is one more thing I want to emphasize. Although scientific research is a race against time, you must also rush for time while ensuring safety. It doesn't matter if you fail once or twice. Don't make anything happen. ACCIDENT!"

"Well, don't worry, Mayor Huang, we know better. We would rather let them postpone the test, and we will ensure safety."

Vice Mayor Huang nodded, feeling a little nervous.

He couldn't help but stand up and walked to the window, looking at the dots of lights outside, looking forward to the results of tomorrow's experiment...

After all, he personally invited Dahan Silicon Industry.

If they can produce results, it will not only make him look good, but also be a long-term good thing for the development of Steel City.

A night of silence.

Early the next morning, the employees of Dahan Silicon Industry came to the company early.

At this time, Dahan Silicon Industry was completely surrounded by cordons.

Although Kangchi has repeatedly emphasized yesterday that this production test is completely within a safe and controllable range, there is no need to make such a big fanfare.

But it was also the first time for the leaders of Steel City to encounter this kind of test.

Especially when I heard that the maximum power of a single crystal furnace was as high as 600KW, I didn't dare to be careless at all and arranged everything I could.

You must know that this 600KW is not used for energy storage and charging, but for real-time energy release. This energy is equivalent to more than 80 households. At the same time, the electrical appliances in the home are pulled to the maximum power that the wires can withstand, which shows the horror of its energy. .

As a result, nearly ten traffic police officers were near the warning line to evacuate outside vehicles and pedestrians.

Within the cordon, three fire trucks and a vehicle from the Power Supply Bureau were also parked quietly.

A little further away, there's even an ambulance,

Looking at this battle, those who didn’t know thought they were doing some kind of drill...

In the test workshop, Kang Chi explained to the leaders who came to watch the test experiment in person: "Actually, 600Kw is only the theoretical maximum power of the design. Generally, under normal operating speed, its power is only about 300Kw."

"That's pretty scary too."

Vice Mayor Huang looked at the humble-looking thing in front of him and could not imagine that it could consume so much power.

Xie Chenggong asked curiously: "Mr. Kang just said the normal operating speed... Are there other operating speeds?"

"Yes." Kang Chi nodded, "The biggest feature of the floating belt method is the purification of single crystal silicon through heating rods and cooling rods."

"If you increase the power, the two rods will move faster and the melting speed will increase. However, just like a computer CPU that is overclocked for a long time and easily burned out, a single crystal furnace is also prone to failure if it is operated at high load for a long time. .”

"However, we have designed an automatic power-off system. Once an abnormal temperature is detected, the equipment will automatically stop running, which can ensure production safety to the greatest extent."

The leaders all nodded after hearing this, feeling relieved.

As the preparatory work before the test ended, the safety personnel began to clean up the scene. Everyone could only stand 20 meters away from the single crystal furnace and watch from a distance.

"The device is started and the test program is started..."

As the engineers pressed the button, the single-crystal furnace, which looked like a large oil tank, finally started running.

Through the quartz glass window on the shell of the single crystal furnace, you can clearly see inside the single crystal furnace. A ring-shaped heating rod gradually heats up and turns red.

Although no change in color can be seen on the cooling rod below, the actual temperature has reached fifty degrees below zero. However, because most of the air in the furnace has been removed in advance, it is in a semi-vacuum state, so there is no appearance on the surface. Obvious hoarfrost.

In the middle of these two circles of rods, there stood a dark polycrystalline silicon rod.

This is the raw material produced by the local silicon refining company in Steel City: polycrystalline silicon rods.

Its material is a bit like the old briquettes, with bumpy surfaces.

This is because its internal crystal structure is very uneven,

The function of the single crystal furnace is to resmelt it into single crystal silicon with continuous crystal lattice and stable electrical properties, while removing excess impurities.

As the temperature of the heating rod increases, the polysilicon rod in the middle finally begins to turn red and then dissolve.

However, the heating rod and the cooling rod cooperate with each other to control the temperature perfectly, keeping the polysilicon firmly at the critical point between solid and liquid, preventing it from flowing.

While smelting, the two rods were also moving slowly.

A few minutes later, the color of the bottom area of ​​the polycrystalline silicon rod had turned gray-white after cooling. The material density was much higher at first glance, and the texture was actually very similar to steel.

At this time, it has completed its transformation from polycrystalline silicon to monocrystalline silicon.

Seeing this scene, Kang Chi was relieved.

In these few minutes, everyone held their breath and stared at the heating rod.

Seeing that Kang Chi seemed to relax, Deputy Mayor Huang finally couldn't help but ask: "Mr. Kang, is this experiment a success?"

Kang Chi shook his head: "It can only be considered a preliminary success."

"We have to wait for another hour to see the details. During this period, the single crystal furnace will melt the silicon rod multiple times at different temperatures according to the different impurity components in the silicon rod."

"After the silicon rods come out, various parameter tests must be carried out. If the results meet the standards, the experiment will be truly successful."

Vice Mayor Huang nodded in understanding.

"Leaders, you can sit down and wait. If something happens, there is no need to waste time here. This test process is actually quite boring. It is not an airplane or cannon, and there is nothing interesting to watch..."

After listening to Kang Chi's words, everyone couldn't help but smile, and the originally tense atmosphere relaxed a little.

"Although Mr. Kang's equipment is not as ornamental as airplanes and cannons, it is no less powerful than them."

After Vice Mayor Huang sighed, he smiled and said,

"I didn't expect that Mr. Kang also has a sense of humor. I used to think that you were a pure-bred science and engineering man. You often turned into all kinds of professional terms that I couldn't understand. I couldn't help but lose focus..."

"Haha, really? I will definitely pay attention to it in the future."

"Well, since we are here in Steel City, we are all friends. There is no need to be so reserved all the time."

Vice Mayor Huang patted Kang Chi on the shoulder, then sat on the chair with everyone, patiently waiting for the test results...
