Black technology: I have a refitting factory

office.

Chu Jianguo sized Su Qi up, his brows furrowed deeper.

Su Qi is too young.

This kind of young guy has not been precipitated, and the things he makes are basically of little value. In normal times, he would patiently chat with this young man for a while.

But today, he was really not in the mood.

The idiot in the sales department, in order to open up foreign markets, dared to promise anything, but was tricked by foreign countries.

The casting parameter requirements were not explained to him, and the contract was signed directly.

It is still a large contract and high compensation.

Later, I found out that I was stepping on a thunderstorm. Let's not talk about how to fix it, but just say that the R\u0026D department's skills are not good enough.

Top-notch!

In the current situation, their company is very passive. If you break the contract, you will have to pay a large sum of money, and your reputation will be damaged, so you don't want to be in the foreign market.

If it is not done well, the reputation of the entire Huaguo foundry industry will be damaged.

The only way to recover is to upgrade the process and make castings that meet the requirements. Not only can it make the cheaters eat yellow lotus dumbly, but it can also open up foreign markets and make Huaguo casting famous abroad.

only……

Speaking of this, he really wanted to scold people.

For the order signed by the salesman, the parameter requirements are fucking outrageous. Don't talk about their companies, it's just a matter of whether the top foreign foundry companies can make them or not.

Upgrade, upgrade a hammer! !

"Mr. Chu?"

A voice woke Chu Jianguo up from his contemplation. Seeing that the young man in front of him was still calm, his agitation became a little less.

The people who came before were all in a hurry, eager to show off their own things. It was the first time he saw someone as calm as Su Qi.

interesting.

Thinking of this, he wanted to have a chat with Su Qi: "Sorry, I lost my mind! Let's go straight to the topic, and you can introduce your stuff!"

"good!"

Su Qi nodded and said, "I'm here this time to discuss cooperation with your company. By chance, I figured out a new casting process.

This casting process, er, how to put it, is half as accurate, durable, and consistent as the current ones on the market. "

"Um?"

Chu Jianguo's originally relaxed face became serious again.

Just now I was thinking that this young man is calm, not anxious, and doesn't look like a boastful person. That's why I wanted to chat a few words.

As a result, come up and say this?

Brand new technology, half higher than the existing ones on the market?

Bragging is not like that!

Seeing Chu Jianguo's expression, Su Qi naturally guessed what he was thinking, and without further ado, he took out a metal ball from his pocket and handed it over: "This is a sample I made, Mr. Chu can take a look first. Take a moment. This one has not been polished, it is a one-shot work.”

Chu Jianguo took the metal ball with a slight frown and looked at it carefully.

The ball is glowing with reflections, the mixture has no flaws, and no pores can be seen, and there is no uneven surface when touched by fingers.

"If it really hasn't been polished, this craft is not bad..."

Chu Jianguo had some judgments in his mind.

With more than 20 years of deep cultivation in the field of casting, the workmanship of a casting can be roughly judged by the naked eye and touch. However, in addition to the precision of the casting process, the number of air bubbles in the cast castings and the bearing pressure are also very important parameters.

These naturally require special testing instruments, which cannot be seen with the naked eye.

"The inside and outside of this ball look the same, without any air bubbles. In addition, this casting is ordinary steel, and the pressure is about 3000kpa."

Su Qi added another sentence.

"No air bubbles? The steel casting is under pressure of 3000kpa?"

Chu Jianguo's expression became a little strange.

For the matter of bubbles, it is still possible to do it with a few more steps in the production process.

But under pressure...

It is theoretically possible for ordinary steel castings to be 3000kpa. But in fact, the most perfect batch of castings is only 2000kpa.

How dare you blow it!

But this young man dared to take out something, is it really possible?

No, it's impossible!

Most likely it's not ordinary steel, or an alloy with something added.

He has heard before that some materials are easy to come up under pressure, but the life of the casting is greatly reduced, which is actually equivalent to a waste product.

It’s okay to use these things to deceive those who have only been in the industry for a few years.

Want to lie to him, huh, huh!

"If there is indeed what you said...it's really good. But if there are only these, I don't really draw conclusions. Can you explain the general process?"

Chu Jianguo didn't intend to expose it immediately, so it's better to hear what else this young man can come up with at this point.

He will use his many years of experience to find out the problem, and then point it out mercilessly.

"Can."

Su Qi nodded.

In fact, he was already ready.

Even if the principle of the process given by the system is stated, without the guidance of specific details, the meaning is not too great.

"The casting process I figured out is layered casting. Taking this ball as an example, the furnace charge contains C, Si, Mn, P, and S in addition to iron. It is smelted in a medium-frequency induction furnace. The first layer is melted. Finally, take samples to check the content of C, Si, Mn, P, S and other elements, adjust according to the results, and then carry out the second layer of melting..."

"Using the layered multiple inoculation method, the multi-element compound inoculation composition is: 1.25% Ca, AI0.9% through multiple inoculations to promote graphitization, eliminate free cementite, and refine eutectic clusters..."

"The size of the gating system adopts the method I discovered by myself, the layered section design method, and the calculation formula is..."

Su Qi naturally picked up a pen and paper from Chu Jianguo's desk and began to write down the formula.

The tip of the pen is flowing on the paper, and the formulas are vividly displayed on the paper.

"This young man seems to have something..."

Looking at the formula on the paper, Chu Jianguo looked at the formula on the paper in surprise.

He had never heard of what Su Qi said before.

But based on his years of experience, it doesn't seem like nonsense, and more importantly, he hasn't found any problems yet! !

Especially for this formula, he felt that his brain and knowledge could not keep up with the speed of the young man in front of him!

He regained the feeling of being in a famous professor's class in college many years ago.

I feel like a novice who doesn't understand anything!

Listening is very difficult!

Numb!

"Um, uh, can you slow down?"

Chu Jianguo's lips moved a few times, and finally he said this sentence.

Don't say no, if you keep listening, he can't listen anymore! !

"Too fast? I've slowed down as much as possible."

Su Qi was taken aback, and subconsciously said.

This thing is really difficult to understand, so he deliberately slowed down when he spoke.
