Black technology: I have a refitting factory

Chapter 18 Can You Speak Slowly (Please Follow Up)

office.

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

Su Qi is too young.

Such young guys have not gone through any preparation, and the things they make are basically of little value.Normally, he would have been able to patiently chat with this young man.

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&D department's skills are not good enough.

Top-notch!
In the current situation, their company is very passive.If we breach the contract, we will have to pay a large sum of money, our reputation will be ruined, and we will no longer want to enter 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 wanted to curse.

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!"

"it is good!"

Su Qi nodded and said, "I am here 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. "

"Ok?"

Chu Jianguo's originally relaxed face became serious again.

Just now I was thinking that this young man was calm, not anxious, and didn't look like a person who would boast.That’s why I wanted to chat for a moment or two.

As a result, this is what you said when you came up?
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 specialized testing equipment and cannot be seen with the naked eye.

"The inside and outside of the ball are the same, without any bubbles. In addition, this casting is just ordinary steel, with a bearing pressure of about 3000kpa."

Su Qi added another sentence.

"There are no bubbles? The steel casting body can withstand a 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...

Ordinary steel castings are 3000kpa, which is theoretically possible.But in fact, the most perfect batch of current castings is only 2000kpa.

How dare you blow it!

But this young man dared to take out something, is it really possible?
No, not possible!

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

He had heard before that some materials were easy to bear pressure, but the life of the castings was greatly reduced, which was actually equivalent to scrap.

It's okay to use these things to deceive people 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, in addition to iron, the charge also contains C, Si, Mn, P, and S. It is smelted using a medium frequency induction furnace. The first layer is melted Finally, take a sample to check the content of C, Si, Mn, P, S and other elements, make adjustments based on the results, and then proceed to the second layer of melting..."

"Using the layered multiple inoculation method, the multi-element composite inoculation composition is: 1.25% Ca, AI 0.9%. Through multiple inoculations, graphitization is promoted, free cementite is eliminated, and the eutectic group is refined..."

"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 the pen and paper from Chu Jianguo's desk and started writing 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 look like he’s just lying. 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!

It’s hard to hear!
numb!

"Um, um, can you slow down a little bit?"

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.
