Xiaomi Heavy Industry, its first entrepreneurial venture!

Chapter 402 Successfully Recreated! (Third Update!)

In the center of the crowd, Lin Yi raised his hands, making a stop gesture.

As he moved, the noise subsided, and a group of people stared at him expectantly, waiting for him to give orders.

Lin Yi didn't speak, but pushed through the crowd and walked to the stove in the corner of the laboratory. The stove had been turned off, but it was still emitting heat.

On the ground next to it lay three molds, each 80 centimeters long, 30 centimeters wide, and 20 centimeters high.

Inside each mold lay a piece of dark metal.

You can feel the high temperature emanating from the metal when you reach your hand over it.

At this moment, Cao Bin also pushed through the crowd and came over:

"For the first batch of materials, we used coolant to cool them down. For this batch, we want to try natural cooling to see if it will affect the performance."

Upon hearing this, Lin Yi recalled the information. The information did not have strict requirements for cooling the smelted materials; either coolant or natural cooling was acceptable.

After all, what we have now is just raw material; it needs further processing to become parts.

Processing techniques are needed both during and after the manufacturing process.

Lin Yi reached out to feel the approximate temperature, then stepped back, increasing the distance between himself and the material.

The lab wasn't air-conditioned, so it was a bit hot and he couldn't stand it, nor did he want to.

Once they were out of the heat, Lin Yi gave Cao Bin an approving look: "No problem!"

"What about large-scale material processing? Have preparations begun?"

When asked about materials processing, Cao Bin couldn't help but sigh, then scratched his head and said, "While they were smelting materials, I took a look at the equipment in the factory."

"The machining process is not the problem; the problem lies in stress relief after the parts are machined."

"The main approach you used in your solution was electrical pulse processing."

“We have the equipment, but it can only process small parts, not large parts.”

"After internal discussions within the technical department, we decided to purchase a set of equipment from the market and then modify it ourselves."

"We informed General Manager Ji and General Manager Liu of this news. General Manager Liu personally went to discuss equipment with suppliers this morning."

"Once the cooperation is finalized, the equipment will be delivered, and then it will be modified and tested. If the entire process goes smoothly without any errors, it will take about a month and a half. If there are any problems, it will take a little over two months."

Cao Bin spoke in a solemn tone, but his excitement was barely concealed.

Electrical pulse treatment is an emerging stress relief technology. Since its discovery by Soviet scientists in the 1980s, countries around the world have been rushing to invest funds and systematically study related technologies.

The principle behind this stress-relief technology is to utilize the Joule heating effect and electron wind effect of instantaneous current to promote the redistribution of dislocations or the migration of grain boundaries within the metal, thereby rapidly releasing stress.

This change is controllable and can further improve material properties.

Having such technology in hand means that the final product of the aircraft carrier deck steel parts may far exceed the requirements of the aircraft carrier team.

Having completed this transaction, Xiaomi Heavy Industry will be able to secure more ship orders in the future.

The names of those present will resonate throughout the world as this technology is widely adopted.

With such a significant contribution, the youth talent development program is no longer important!

Sensing the excitement in his voice, Lin Yi turned around and found that, apart from Cao Bin, everyone else also had barely concealed excitement on their faces.

The most excited was Gao Hai.

He stood next to the mold like a monkey ready to snatch chestnuts from the fire, constantly reaching out his hand. When his hand felt the temperature of the material, he quickly withdrew it, only to reach out again and again.

Seeing him like this, Lin Yi could only sigh and point at the materials:
"Cao Bin, cool it down with coolant, then quickly conduct tests and show them to our Representative Gao!"

"Alright! Send a few people to drag the cart over and move this thing to the cooling pool. Get the cutting table ready. Everyone else, go back to your posts. Once you've received your materials, start the testing." With Lin Yi's instructions, the group stopped insisting that the materials cool down naturally. In just a few words, Cao Bin had assigned the tasks.

The sound of a diesel engine rang out, the crowd dispersed, and a small forklift crossed the crowd and appeared next to the mold. The forks reached under the mold, the hydraulic press exerted force, and the forks lifted the mold.

A bit heavy.

Amidst the roar of the diesel engine, a forklift carried the mold out of the laboratory and into the adjacent cooling room. With a thud, the entire mold was thrown into the quenching oil.

The forklift, having discarded the mold and unloaded its weight, made a clean reverse and plunged back into the lab. Just as it was about to leave with the second mold, Cao Bin suddenly asked:
"Um... there are no hooks on the mold, right?"

In short, the excitement on the forklift driver's face vanished without a trace, leaving only a look of terror.

With a terrified expression, Cao Bin covered his face with his right hand:
"You jump in and retrieve it! The rest of you, continue!"

After leaving those words, Cao Bin, hunched over, walked step by step toward the next room.

Behind him, the forklift driver looked like he was about to cry.

This is the laboratory, where the main work is experimentation. The materials and parts produced are usually small, so the cooling pool is not equipped with a large overhead crane, and naturally there are no common electromagnets.

All that's there is is a gantry crane mounted above the cooling pool and a small overhead crane weighing one ton.

I was so excited that I threw the mold and the material that needed to be cooled into the cooling pool. Now, if I want to retrieve it, I have to go down manually and hang the hook on the mold.

But it contains quenching oil!

油！
The forklift driver screamed and carried the second set of molds to the cooling pool. This time, he didn't throw the molds in all at once. Instead, he waited for someone to come forward, hook up the small overhead crane, and watch as the crane lifted the molds and slowly lowered them into the cooling pool.

After the second set of molds cooled down, it was manually transported by another forklift to the cutting table.

On the cutting table, the operator removes the mold, leaving only the raw material in the middle.

Instead of cutting it immediately, they first used equipment to grind off the oxide layer of the raw material.

After some polishing, the originally dark raw material turned into a brilliant silver-white, and the polished areas even showed a mirror-like reflection.

The next second, the cutting machine started operating, cutting the 80-centimeter-long raw material into three sections. Then, these three sections were stood up and evenly cut into eighteen slices.

These nine pieces of material were loaded onto a tray and sent to the adjacent testing laboratory.

Different testing items require different laboratory configurations, so these eighteen pieces of material were sent to different testing laboratories.

Once they received the materials, a group of people in the testing lab, eager to get started, immediately began working.

Compressive strength, tensile strength...

Gao Hai, who witnessed the whole thing, was the busiest person in the lab. He would peek out from the door of one lab one moment and then from the door of another the next.

Unlike him, after the test started, Lin Yi found a stool, found a quiet spot to sit down, closed his eyes, and went to sleep.

From sunset to a sky full of stars, as Gao Hai once again rummaged through the door, Cao Bin handed the man a report:
"Representative Gao, the results are in. Take a look."

The report was only one page long, light and flimsy, and was sandwiched between the two of them. When the breeze blew through the corridor, the paper swayed in the wind.

As the paper swayed, Gao Hai could still vaguely make out the words on it.

He dared not accept it; he was afraid it was all a dream, afraid that if he took the paper, he would wake up from this dream.

Then the people around him would tell him that there's no such thing as producing aircraft carrier steel in a few days; it's just a bunch of losers indulging in wishful thinking.

After a while, Cao Bin noticed that Gao Hai wasn't taking the report, so he simply stretched his hand forward a little further and slapped the report directly into Gao Hai's hand. The paper was in his pocket, leaving Gao Hai no time to think.

He hurriedly took the report, quickly straightened it, and looked straight down to the bottom to see the conclusion.

Below the conclusion, there is only a short line of text.

This steel formula meets the requirements for aircraft carrier deck steel!

Below this line of text are an unfamiliar person's name and a familiar organization's name.

Xu Wenjun

[China Shipbuilding Industry Corporation 0785 Metal Materials Research Institute]

After reading the conclusion, Gao Hai's gaze fell back to the front of the report, to the series of comparative data.

For the same project name, there are three sets of data: one set is the design requirements, and the other two sets are the test data from two separate tests.

【抗拉强度：设计值≥700MPa；第1轮检测值：934MPa，第2轮检测值：937MPa。】

【屈服强度：设计值≥600MPa；第1轮检测值：671MPa，第2轮检测值：677MPa。】

【延伸率：设计值≥15.5%；第1轮检测值：17%，第1轮检测值：17.2%。】

Impact resilience...

Salt spray corrosion rate...

[Critical pitting temperature for resistance to seawater pitting corrosion...]

[Welding carbon equivalent...]

The measured data all exceeded the theoretical design requirements, and by a significant margin.

Looking at these data, tears of emotion welled up in Gao Hai's eyes without him even realizing it.

Such high-quality materials are sufficient even if we postpone their use for ten years, for future aircraft carriers or ships.

But he quickly stopped crying.

Because technology is advancing, he can't even imagine what Xiaomi Heavy Industry will produce in 10 years, or what the landscape will look like in 10 years.

Unable to come up with an answer, Gao Hai decided to stop thinking about it and focus on the report in front of him.

I'll take this report with me and leave Suzhou to meet Lin Ze at Jiangnan Shipyard, and then head to the Shipbuilding Heavy Industry.

As Gao Hai was engrossed in reading the report, he heard footsteps beside him. The footsteps stopped beside Gao Hai and then fell silent.

After a while, Gao Hai finally finished reading the report. He looked up, about to ask Cao Bin a few questions, when he noticed someone standing next to him.

I've seen this person at a conference related to the 001 aircraft carrier, but I don't know his name.

Looking back now, it must have been the person who signed the report—Xu Wenjun.

Nodding to the other person, Gao Hai took the initiative to ask:

"Professor Xu, what do you think?"

Xu Wenjun did not answer immediately. Instead, he braced his left hand against the door frame, took a deep breath, and then exhaled forcefully.

After exhaling, he gave Gao Hai a sharp salute:

“Representative Gao, I am here to apologize to you on behalf of myself a few days ago. As a frog in a well, I should not have questioned General Manager Tan’s decision or the decision of the General Armament Department.”

"sorry!"

After bowing deeply to Gao Hai, Xu Wenjun straightened up and bowed sharply to Cao Bin beside him.

The sudden movement startled Cao Bin, who quickly moved aside and turned his questioning gaze to Gao Hai.

Xu Wenjun, standing between the two, noticed Cao Bin's gaze, gave him an apologetic smile, and explained in a low voice:

“A few days ago, when I received orders from General Manager Tan to organize the materials and then come to Xiaomi Heavy Industry with Representative Gao, I was very angry.”

"There's a saying that every profession is like a mountain to climb. At the time, I thought that Xiaomi Heavy Industry was a leader in the satellite and battery fields, but that didn't mean it was a leader in the metal field."

"I said some harsh words to him in private at the time."

"Now, I apologize for those harsh words I said in private!"

"I, Xu Wenjun, am a frog in a well!"

“From today onwards, Chief Engineer Cao, if you tell me to go east, I will absolutely not go west; if you tell me who to attack, I will attack them.”

The next second, Cao Bin's joking voice rang out: "Go and beat up our boss!"

Upon hearing such an outrageous request, Xu Wenjun immediately shook his head:

"No way! Even a minor bump or bruise on someone as smart as Mr. Lin is a loss. You want me to fight? You want me to die!"

Cao Bin continued to joke, "Then if I told you to go east, you would definitely not go west!"

Seeing that the two were about to go off on a tangent, Gao Hai quickly stopped them: "You're both sure it's done, right?"

Getting back to work, Cao Bin immediately dropped his joking expression and nodded emphatically:

"Sure!"

"The second batch produced three samples, and there are two more samples there. You can take them all with you later."

He was touched to hear that two samples had been specially reserved for him to take back, but he quickly remembered that only three samples had been made from this batch of materials.

A piece has been cut from the experiment conducted this afternoon.

If he takes two pieces with him, it means Cao Bin will have no samples left.

Looking at him with a puzzled expression, he asked, "Don't you want a sample?"

Meeting his gaze, Cao Bin nodded, then shook his head: "The purpose of making the second batch of samples is to reproduce the first batch."

"What I need to do now is to achieve stable reproduction!"

"There will be a lot of samples coming up, and some will even have to be thrown aside and kept as souvenirs."

Hearing Cao Bin's words, Gao Hai immediately felt reassured. He carefully folded the A4 paper in his hand, placed it carefully in the pocket of his left breast, and pressed it down firmly.

After confirming that the samples were in place, he nodded to Cao Bin and said, "Chief Engineer Cao, could you please arrange a vehicle to load those two samples onto the truck and then take me to Jiangnan Shipyard?"

When Gao Hai asked for help, Cao Bin did not respond immediately. Instead, he walked over to Lin Yi, who was sitting in the corner of the corridor, asleep against the wall.

He woke the man up and repeated Gao Hai's request to Lin Yi.

After hearing the request, Lin Yi rubbed his temples and instructed, "Have the security department send a few more people. Make sure the person is safely delivered to the shipyard!"
