Chapter 67 Production Testing
When Vice Mayor Huang first heard the news, he almost thought he had heard it wrong.
"They have only been in the market for more than a month, and they have 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, and they have now submitted an application for experimental reporting to the power supply, fire protection and other departments."
"So what are you waiting for? Hurry up and get all departments moving and fully cooperate with their experimental tests! ”
"Okay, I'll go down and arrange it right now."
"Hmm...... Wait a minute, there is another thing I want to emphasize, although engaging in scientific research is a race against time, but rushing for time must also be on the premise of ensuring safety, it doesn't matter if you fail once or twice, don't make any accidents! ”
"Well, Mayor Huang, don't worry, we know in our hearts, and we would rather let them postpone the test, but we will definitely ensure safety."
Vice Mayor Huang nodded, and couldn't help but feel a little nervous.
He couldn't help but stand up, paced to the window, looked at the lights outside, and looked forward to the results of tomorrow's experiment......
After all, Dahan Silicon was personally invited by him.
If they can produce results, it will not only make him have a bright face, but also a long-term good thing for the development of Steel City.
Nothing was said all night.
Early the next morning, the employees of Dahan Silicon came to the company early.
At this time, Dahan Silicon Industry has been completely surrounded by a cordon.
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 the leaders of Steel City are also encountering this kind of test for the first time.
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 that could be arranged.
You know, the 600KW is not used for energy storage and charging, but real-time energy release, which is equivalent to more than 80 households, and at the same time pull the home appliances to the maximum power that the wires can bear, which shows the horror of its energy.
As a result, nearly ten traffic police officers are near the cordon, evacuating outside vehicles and pedestrians.
Inside the cordon, three fire trucks and a car from the power supply bureau were also quietly parked inside.
A little further away, there's even an ambulance,
Looking at this battle, those who don't know think that they are engaged in some kind of exercise......
In the test workshop, Kangchi explained to the leaders who came to watch the test experiment in person: "In fact, 600Kw is only the theoretical maximum power of the design, and its power is only about 300Kw under the general normal operating speed. ”
"That's scary, too."
Vice Mayor Huang looked at the unsightly thing in front of him, and couldn't imagine that this thing could consume so much power.
Xie Chenggong asked with some curiosity: "Just now, Mr. Kang said that the normal operation speed ...... Is there any other speed? ”
"Hmm." Kangchi nodded, "The biggest feature of the floating belt method is that the purification of monocrystalline silicon is achieved through heating rods and cooling rods. ”
"If the power is increased, the movement speed of these two rods will be accelerated, increasing the melting speed, but just like the computer CPU is overclocked for a long time and is easy to burn out, the single crystal furnace is also prone to failure if it runs at high load for a long time."
"However, we have designed an automatic power-off system, once the temperature is abnormal, the equipment will automatically stop running, which can ensure production safety to the greatest extent."
After hearing this, the leaders all nodded and felt a lot more relieved.
As the pre-test preparations were over, the safety officers began to clean up the site, and everyone could only stand twenty meters away from the single crystal furnace and watch.
"The device is booted up, and the test program starts ......"
As the engineers pressed the button, the monocrystalline furnace, which looked like a large oil tank, was finally up and running.
Through the quartz glass window on the shell of the monocrystalline furnace, you can clearly see that inside the monocrystalline furnace, an annular heating rod gradually heats up and turns red.
Although the color change of the cooling rod below can not be seen, the actual temperature has reached 50 degrees below zero, but because most of the air in the furnace has been pumped out in advance, it belongs to a semi-vacuum state, so there is no obvious hoarfrost on the surface.
In the middle of these two circles of rods, there is a black polysilicon rod.
This is the raw material produced by the local silicon smelter in Gangcheng: polysilicon rods.
Its material is a bit like the previous briquettes, with potholes on the surface.
This is because its internal crystal structure is very uneven,
The function of the monocrystalline furnace is to re-smelt it into monocrystalline silicon with continuous lattice and stable electrical properties, while removing excess impurities.
As the temperature of the heating rod rises, 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 very perfectly, and the polysilicon has been firmly controlled at the critical point between solid and liquid state, so that it does not flow.
While smelting, the two rods were also moving slowly.
After a few minutes, the bottom area of the polysilicon rod has changed to gray-white after cooling, and the material density is much higher, and the texture is actually very similar to steel.
At this time, it has completed the transformation from polysilicon to monocrystalline silicon.
Seeing this scene, Kangchi was also relieved.
For a few minutes, everyone held their breath and kept staring at the heating rod,
Seeing that Kang Chi seemed to be relaxed, Vice Mayor Huang finally couldn't help but ask: "Mr. Kang, is this experiment a success?" ”
Kang Chi shook his head: "It can only be regarded as a preliminary success." ”
"We have to wait for an hour to see if we have to wait for this time, during which the single crystal furnace will use different temperatures to melt multiple times according to the different impurities in the silicon rod."
"When the silicon rod comes out, we have to test various parameters, and if the results are up to standard, the experiment will be truly successful."
Vice Mayor Huang nodded as if he didn't understand.
"Leaders can sit down and wait slowly, if there is something, there is no need to spend it here, this test process is actually quite boring, and it is not an aircraft cannon, there is nothing to watch......"
After listening to Kang Chi's words, everyone couldn't help but smile, and the originally tense atmosphere eased a little.
"Although Mr. Kang's equipment is not as ornamental as the aircraft cannon, it is not less powerful than them."
After Vice Mayor Huang sighed, he said with a smile,
"I didn't expect Mr. Kang to have a sense of humor, I used to feel that you were a purebred science and engineering man, and when you often talk and talk, it has become a variety of professional terms that you don't understand, and I can't help but often wander when I hear it......"
"Haha, huh? I'll be sure to pay attention in the future. ”
"Well, since you have come to Steel City, then everyone is friends, so there is no need to be so restrained all the time."
Vice Mayor Huang patted Kangchi on the shoulder, and then sat in a chair with everyone, patiently waiting for the test results......
