Craftsman: I continue to learn for the sake of the saints

Chapter 168 Proficiency and Thinking
At the same time that Qin Luo dropped the hammer, several old masters, including Qin Guangrong, also watched intently.

What's the point of dropping the hammer?
Different foundries have different methods.

However, when Qin Luo "dangdangdang" opened the hammer, everyone was particularly surprised to find that Qin Luo's hammering method was very peculiar.

Neither fast nor slow, neither light nor heavy, the force of each hammer seems to be even in size.

and……

Compared with the normal beating on the sword embryo, Qin Luo's hammer is a bit like "a hammer in the east and a mallet in the west."

The parts to be hit are very chaotic and disorderly, without any rules at all.

As for the shape of the sword embryo, under his hands, it gradually became more and more "distorted".

In all fairness...

Such a "result" is a bit like a novice, looking very bad.

But, unfortunately, Qin Luo was very skilled in hammering.

Moreover, it has not been fully formed yet, making it impossible to judge what the final finished product will look like.

Zhang Ziqi looked at it for a while, and couldn't help laughing: "What kind of hammering method is this? It's a bit like the legendary chaotic cloak..."

This is of course a joke.

Does he know how to use a fart hammer?

I just read a few martial arts novels.

Qin Luo kept moving his hands and didn't raise his head, but when he heard Zhang Ziqi's words, he still responded with a smile: "This name is good, and it's quite vivid."

"It should be from a martial arts novel, right?"

"The person who created this name may have seen this way of tempering."

At this time.

An old master couldn't help but interjected and asked, "What's the use of this?"

I don't understand.

I don't understand.

Qin Luo still didn't look at him, and the movements of his hands still didn't stop, but he was unreserved, telling them the principle.

"stress."

"From the perspective of energy doing work, when an external force causes an object to undergo plastic deformation, it will cause deformation inside the object, thus accumulating a part of energy."

"When the external force is removed, the energy of uneven internal stress distribution will be released. If the brittleness of the object is low, the object will deform slowly, and if the brittleness is high, cracks will form.

This is a principle of physics.

I have studied physics.

When learning forging in the system space, Qin Luo found corresponding theoretical support for every step taught by the teacher.

Although, the ancient swordsmiths did not understand these highly generalized theories.

However, after thousands of times of practice, they have found the perfect way to use it.

"Can you understand?"

"Residual stress release is the root cause of deformation during quenching."

"This piece of iron, you hit it, and it didn't respond? Actually, there is, but it reacts slowly. But once the temperature increases, the molecular motion speeds up, and it begins to explode."

This is the basic theory.

Qin Luo said it in a more humorous language.

Sister Cha and Yang Zi, who knew nothing about blacksmithing, understood.

Naturally, these old masters have known this for a long time. A master who seemed to be in his 40s suddenly patted his forehead and said with a sudden realization: "Through beating techniques, can the stress be reduced to the greatest extent?"

"But... how can there be such a skill?"

"How did it happen?"

He got it.

Of course, this principle is not difficult.

It's just that it's really difficult to do it.

Stress is invisible and invisible, and its roots are hidden inside the metal. Even modern casting requires professional equipment to detect it. How can you detect it with the naked eye during the beating process?
Or, purely by feeling?

The rhythm of Qin Luo's beating did not change at all, nor did he raise his head, and his tone was still calm and steady.

"Without it, only hands are familiar with ears."

Teacher: ...

Qin Guangrong: ...

Zhang Ziqi: ...

These six words are really a master of pretentious skills.

However, you, a "doll" who looks less than 30 years old, how can you compare your proficiency with a group of forty, fifty, and 60-year-old old masters?

"So I've been playing iron all my life, but I'm not familiar enough?"

An old man with gray hair and dark complexion said with some dissatisfaction and doubt.

Qin Luo thought for a while.

"Are you a set of experiences that you have used for a lifetime? Or have you been pondering, trying, summarizing, practicing, reflecting, improving...and then continue this process, over and over again, to improve?"

Hearing this, the old man suddenly fell silent.

I suddenly felt a little uncomfortable in my heart.

He understood what Qin Luo meant.

It's just that I suddenly felt that it was too late to understand.

"We will do what Master taught us."

He whispered, murmured.

It seems to be explaining, more like making an excuse for myself.

Saying this, I will feel better in my heart.

"But what if the master is wrong? What if the master can't do it? What if the master hides something from you?"

Qin Luo said calmly.

Paused.

No longer entangled in these "people and things" issues, continue to talk about craftsmanship.

"This set... can be named as the random cloak wind hammer method. The most fundamental purpose is to eliminate stress as much as possible during the construction stage."

"As for how to operate it when casting, you need to have high-level thinking."

"For example, when I hit the hilt with a hammer, in which directions is its stress distributed? How much force should each bear in each direction, how to do the force analysis, and the next hammer, should it fall? Where can these dispersed stresses be dispersed again...so, the third hammer, the fourth hammer...and...every subsequent hammer..."

"It's like climbing a ladder to the sky. The further you hit the back, the more stress you have to deal with."

"At this time, the inside of the sword embryo has become an entropy-increasing system, and the degree of chaos and disorder of stress is increasing rapidly with each hammer you strike... You have to rely on your own hammer to re-beat it into entropy. No increase, no decrease.”

"In addition to the problem of proficiency, there is also the problem of thinking."

"Just these two points."

Qin Luo narrated the essence of his hammering technique.

He has tried to use simple language, "speaking human language".

However, it may still be a little difficult to understand. The old masters frowned tightly, and their eyes revealed confusion.

What?
what what?
What is this saying?

I really don't understand.

Among these people, most of the masters have primary school education and junior high school education, and Qin Guangrong is a technical secondary school student, but he still feels that he doesn't understand much.

Seems to understand.

Zhang Ziqi understood.

Sister Cha doesn't quite understand.

But Yang Zi understood it completely.

She felt that the theory master taught was really awesome.

Not only can it be used in blacksmithing, but it can even be used in other fields of artistic creation.

Even jade carving is fine, or painting or writing is fine.

For any piece of work, it is easiest when the "first hammer" is dropped and the "first stroke" is written.

But as the work progresses, there are more and more factors to consider.

All the workload you have done in front of you has become a limit to continue to advance.

Seeing that everyone was deep in thought, Qin Luo didn't say much, and let them digest.

He continued to beat himself.

He has a wonderful feeling.

What I said just now can be said to be the most real realization I have made during this period of time.

The progress is still considerable.

Under the ever-changing thinking, the understanding of art has risen from the general laws of specific fields to the general laws applicable to most art fields.

To put it a little more mysteriously - technology, almost Tao.

And the path I have summed up has two core points, one point is the amount of thinking, and one point is proficiency.

Think ahead.

Proficiency comes later.

……

About two hours later.

The sword embryo of this Golden Snake Sword gradually took shape under Qin Luo's beating again and again, and began to show the state of the finished product.

Qin Guangrong and several teachers and parents came together to check again.

After a few detailed glances, Qin Guangrong frowned slightly.

"Master Qin, this... the spine of the sword is not straight."

He said with some apprehension.

Improper ridge line is definitely a big taboo in the sword casting process. It can be said that this sword is almost useless.

However, he is not sure now whether Qin Luo did it on purpose.

With the level Qin Luo showed just now, it is impossible to make such a low-level mistake.

Qin Luo waved his hands and smiled.

"Yes, the sword spine line is indeed not straight."

"However, after burning, it should be almost right."

"Try it in the fire."

"Stress, even now, can't completely disappear, and there will still be some left. At this time, it needs to be fully released. This error is the amount of modification I left."

"Negatives make positives."

"Of course, there are calculation and judgment errors, and the possibility of overturning, but let's try first."

Qin Luo explained.

Qin Guangrong was dumbfounded.

This kind of high-end operation makes my scalp tingle just thinking about it.

After the second-formed sword embryo was thrown into the furnace, Qin Guangrong couldn't help but heaved a long sigh.

"Science and technology are still primary productive forces."

"knowledge is power."

"You said, we don't have enough theoretical reserves, really, hahaha, I can't even understand it."

He flattered.

It's not all flattering, and I really think so in my heart.

Qin Luo is not easy to respond to these words.

Zhang Ziqi smiled and said: "Go back and get your son's physics textbook, read more, ah, it's actually quite simple. Or, how about this, this year's fresh graduates, there are still dozens of employment places that have not been secured, I will give you Divide into five?"

In his position to seek his government.

Zhang Ziqi is also considering his performance and employment issues.

Qin Guangrong: ...

Immediately speechless, looking at Zhang Ziqi in disbelief, he felt a kind of taking advantage of the fire.

The income in the factory is also limited, and there is not much demand for manpower for the time being, but he can't refuse this kind of words forcefully. After thinking about it, he naturally smiled: "If it's like Mr. Qin, we need as many as we have here. , but if you're fooling around, don't make trouble for me. I can't stand it."

Hearing the meaning of refusal, Zhang Ziqi laughed, but he was thinking in his heart, and patted Qin Guangrong on the shoulder.

"Hey, masters are all grown up from rookies. Send people over first. The theories of the young people, plus the experience of the old masters, learn from each other and improve each other. Brother Luo, why don't you give me a consultant? Come and give pointers."

He still wanted to create more jobs, and even put his mind on Qin Luo, and at the same time, he gave Qin Guangrong some compensation.

You help me guide college students, and I will find you a thigh as a consultant.

Qin Luo... for a moment burst into laughter.

"You really have a dark heart, so you dragged my young man? Is there a salary?"

Qin Luo laughed jokingly.

Zhang Ziqi laughed.

"Those who are capable work harder, and those who are capable work harder. Salary... a meal of wine a month, I invite, is it okay?"

Qin Luo: ...

"Go to hell."

"You don't drink below Moutai..."

Qin Luo still agreed.

If I want to make swords myself, I still need a place. The village is obviously not suitable, so I decided here.

As for those who don't have money, they don't have much money.

Zhang Ziqi laughed: "Okay, Maotai is Maotai, Feitian can't afford it, 42 degrees is still okay."

Qin Luo: ...

You are a real dog!
Cut to death.

However, if he wants to treat himself to Feitian, he will be afraid.

Where did the money come from?

……

The sword embryo has been thrown into the fire.

is being fired.

It was almost noon now, and Qin Guangrong had already sent out a meal, which was in a small box in the canteen of the factory.

After hearing the conversation between the two, he deliberately took out his own wine.

Although Qin Guangrong is still a little cautious, he still respects those who are really capable.

while eating.

Taking advantage of the good atmosphere, he took advantage of the opportunity to propose: "Master Qin, the demand for this time is a total of fourteen swords. Look, if they are really fired, look, this hammering method, is it for us to train intensively?" one time?"

The task still needs to be completed.

There are fourteen in total, and it is unrealistic for Qin Luo to fight alone.

Besides, I still want to learn art very much.

It is better to teach a man to fish than to give him a fish.

Qin Luo smiled: "It's not difficult. In fact, there are more than just means to eliminate stress. Elimination is the source during forging, but there are also ways to eliminate it during quenching."

"Residual stress can be divided into three categories."

"The first type, non-uniform plastic deformation, the second type, non-uniform temperature change, and the third type, non-uniform phase transformation."

"Hammer method, the first class to solve."

"As for the second category...it's also simple. In fact, it's the main problem you faced before."

Teacher Qin's small class has started again.

Qin Guangrong wanted to take out his small notebook and write down these words.

"Say it, tell it, I'm listening..."

His tone was even a little flattering.

The secret!

The second secret!

Sure enough, there are still some!
This wine is not in vain!
Qin Luo put down his chopsticks and spoke slowly.

"Stress has a limit value. When the two types of stress are superimposed, the degree of deformation will intensify, and the finished product will naturally have problems."

"However, as long as one of the two kinds of stress can be resolved, the problem should not be too big."

"I'll teach you how to solve the problem of the second type of stress, uneven temperature changes, which can be solved by creating heat reflection."

"The ancient people's solution to this is very simple, just one process, two words - tiling."

Tiling?

"oops!"

Qin Guangrong slapped his thigh suddenly, stood up abruptly, a little carried away with joy.

A word to wake up the dreamer!

Truth is just one sentence.

They thought of countless ways to solve the unstable changes in the furnace temperature, but they didn't get any results.

As soon as Qin Luo talked about the tiling process, he quickly understood what it meant.

After the originally open furnace is covered with tiles, the heat energy is repeatedly refracted in the furnace, so the furnace temperature is even, and all problems disappear.

As long as the furnace temperature is uniform, there will still be stress even during the forging process, but after quenching, it will not be so easily deformed.
