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

Chapter 167 Sexy anchor, blacksmithing online

The third state-owned sword factory in the west of the city.

Arriving soon.

Before entering the gate, Qin Luo already saw a gray-haired man in his fifties at the concierge, with a cigarette in his mouth, walking back and forth anxiously waiting.

"Factory manager?"

Qin Luo looked at Zhang Ziqi and asked a question.

"That's right, old Qin, Qin Guangrong."

Zhang Ziqi said with a smile.

Seeing the car stop, Qin Guangrong walked over immediately with a bright smile on his face.

"Mayor Zhang..."

He took the initiative to open the car door, and looked in, but only saw that except for Zhang Ziqi, Qin Luo's three people did not have the experts he imagined.

So the smile froze slightly for a while.

Look back again.

Seeing that there was no second car, he immediately looked disappointed.

The three young men in the car couldn't possibly be experts, could they?

"Where are the experts?"

As soon as Zhang Ziqi opened the door and got out of the car, Director Qin handed him a cigarette and asked with a sneer.

Zhang Ziqi laughed.

He nuzzled at Qin Luo.

"Isn't that right? Come on, let me introduce you, Qin Luo, my college classmate, he's awesome. He was the one who talked to you just now."

"Old comrades, don't be so blind. What's the matter, young people are not experts?"

Hearing what he said, Director Qin couldn't help but look at Qin Luo.

Although there is still a bit of suspicion in the eyes, but also a bit of faith.

Grinning, he shook hands with Qin Luo: "Welcome, welcome, welcome Master Qin to come to our factory and guide the work."

"We're in the same family."

Qin Luo shook hands with him and smiled: "It's not about guidance, we learn from each other."

Hearing this voice, Qin Guangrong immediately believed it.

This is the voice of the phone call just now, calm and calm, very generous.

A few greetings.

Several people walked towards the interior of the factory.

This factory looks really old.

The interior obviously hasn't been updated for a long time.

Even the slogans on the wall are still full of the characteristics of the times - Zhongshan is turning green with wind and rain, and millions of soldiers cross the river.

When I got to the factory, I didn't see a modern assembly line, all of them were handmade.

Even the sword stove is ancient.

The main feature is an authentic taste.

Of course, some basic facilities for water supply and drainage, air supply, and electricity are still available.

it looks...

It's a bit like a small workshop that "just works".

but.

Qin Luo's eyes were quickly attracted.

At this time, a master was sharpening his sword.

Hand milled.

In fact, the process of sharpening a sword is more labor-intensive and time-consuming than casting the sword itself.

There is a poem that says that the edge of a sword is sharpened.

The effort consumed in the sharpening process is one of the core competitiveness of hand-casting swords that cannot be mass-produced by machines.

Qin Luo looked at it intently for a while.

When sharpening a sword by hand, the main test is stability and the exquisite grasp of the angle of the blade.

The angle is too big to grind out.

If the angle is too small, it is easy to curl the edge.

This old master who is sharpening his sword is obviously of the kind with extremely superb skills, his movements are extremely stable, like a precision machine, and it looks like a harmonious beauty, which is the benefit of obsessive-compulsive disorder.

Seeing Qin Luo stop, Factory Manager Qin didn't urge him, but only flirted with Zhang Ziqi, as if he was still sizing up Qin Luo's quality.

"Which student is Master Qin?"

Qin Guangrong asked with a smile at this moment.

There are only a few sects of swordsmiths in Longquan, and there are not many people themselves. Basically, they have names and surnames, and those who are famous can be known when they mention their names.

this problem……

Qin Luo has heard it countless times.

Almost everyone who has not set foot in a new field will be asked.

It's really annoying.

However, this is the biggest feature of traditional handicrafts, and it is also the most difficult to describe.

"Teacher" is actually a subordinate relationship in social hierarchy and power status.

"Under the tutelage of Ou Yezi."

Having answered many times, Qin Luo now has experience, so he just opened his mouth.

Qin Guangrong:? ? ?

Immediately froze slightly.

Zhang Ziqi laughed and smoothed things over: "My brother likes to joke, haha, don't take offense, Lao Qin, let's go, go and see the Golden Snake Sword, after all, it's a mule or a horse, you'll know if you take it out for a walk."

"However, if it doesn't work, you don't mind."

"You can't do it yourself well, Qin Luo, I just came here to help, so it's best if you can help."

He said the ugly words first.

So as not to wait and smash it.

Although Qin Luo seemed to understand it very well, and he was able to accurately find out the problem, which can be regarded as showing his hands, but he couldn't guarantee the specific practical experience.

Because I have never seen it.

Qin Guangrong glanced at Qin Luo again, but for Zhang Ziqi's sake, he didn't say much, just leading the way.

……

There are a total of 28 processes in the hand-crafted Longquan sword, which is extremely complicated.

From raw materials to finished products, it has to go through billeting, hot forging, shoveling, filing, engraving, copper inlaying, polishing, decoration and so on.

Among them, the main process is 6 steps.

Hammering: The iron block is melted in the furnace, and the sword blank is made by carburizing process, which is repeated many times. The degree depends on the quality of the sword. This is a key step in determining the quality of a sword.

Planing file: Cut the file with a steel knife so that the thickness of the sword body is moderate, and there is a certain slope between the sword spine and the blade. The sword spine must be in the middle of the sword body and be in a straight line.

Polishing: Put the filed sword on the stone to polish it.Rub evenly with an iron ruler wrapped in emery cloth.Grind first with coarse sand cloth, then with fine sand cloth.Polishing works twice as much as hammering and planing.

Inlay: After polishing, use a steel needle to engrave the pattern, sword name, shop number, and the inscription of the customizer on the body of the sword; the craftsman engraves the pattern without tracing the pattern, and only uses a steel needle on both sides of the sword body that is only an inch wide Needle free.

Quenching: Using the traditional quenching method, after "strong forging", a special quenching agent is used for "softening" treatment, so that the sword body can be both rigid and flexible, and can be bent and stretched.Pay attention to the control of temperature and time.It is a high-precision craftsmanship, which is not handy for ordinary craftsmen.

Steel grinding: use a steel block to sharpen the elastic sword; or use a steel ruler to tighten the sword body and place it on a stone for grinding.There is a mountain in Longquan Beixiang, which is a specialty of Cuoshi, commonly known as "Bright Stone".After the sword is ground by "bright stone", it does not need to be plated with nickel, and the body of the sword shines brightly.

The kung fu honed by a sword shows the master's high level of craftsmanship.

Coarse grinding - fine grinding - fine grinding - glazing and more than a dozen processes, the tools used are also different.

In this "semi-old" workshop, every process flow can be seen.

It looks a bit like an assembly line.

The temperature inside is much higher than outside.

Qin Luo soon saw the "Golden Snake Sword" that failed to forge.

The characteristic of the Golden Snake Sword is that although the body of the sword has various curvatures, the body of the sword itself is still straight, and the tip of the sword and the hilt must be a straight line.

The sword spine will never bend.

but……

Now what they have forged is completely "Qimen", even the spine of the sword is bent.

Of course, this situation is also normal.

Flexible curves are not so easy to make.

"Before we forged the sword, we also asked many experts to study it. The Golden Snake Sword has not been done for a long time."

"Whether it is materials or craftsmanship, it is difficult to find inheritance."

"A dozen masters in the factory have studied for a long time, but they have solved the material problem. As for the length of the sword, the above requirement is 1.2 meters. However, the stress of the short sword can be solved, but the length only needs to exceed [-] centimeters. , during heat treatment, it will be deformed in various ways.”

Qin Guangrong seemed a little embarrassed and said.

This task is very important.

However, it is also difficult.

A lot of hard work and energy have been put in in the early stage, but at the most critical moment, this kind of problem is simply too tortured.

and……

There is no existing experience to refer to.

Compared with a straight sword, the difficulty of forging the Golden Snake Sword has increased by dozens of times.

Qin Luo nodded and didn't say a word for the time being, just looked at their various equipment for making swords seriously.

Qin Guangrong coughed dryly.

After thinking about it, he opened his mouth to rule out various wrong options.

"Tried tempering, but it didn't work."

"In addition, I also tried to modify the air duct and use the wind to even out the temperature of the furnace, but it still didn't work."

"Later, I also thought that it had something to do with the fuel, so I deepened the furnace, changed the size of the fuel, and tried to make the temperature as uniform as possible, but it still didn't work."

"So far, there have been a total of 87 failures. Wait a minute, I'll show you the detailed sword casting log."

Qin Guangrong said in a deep voice.

Forging a sword once is not that easy.

He has five groups of people working at the same time, almost like doing an experiment, looking for changes in every detail, using control variables, hoping to completely solve this technical problem.

However, after failing so many times, there is still no clue.

The already sparse hair volume is becoming more and more dangerous.

"Can modern machines be built?"

Zhang Ziqi asked curiously at this moment.

He really doesn't understand technical things.

Qin Guangrong pursed his lips.

He took out a cigarette to light one, and let out a long puff of smoke.

She glared at him, but was too lazy to argue.

nonsense!

If this is done with modern molds and machinery, it is a matter of opening a mold.

but……

"Go and talk to the leaders of the foreign affairs office, let them leave the task to the steel factory, my small workshop can't afford to take care of it."

Qin Guangrong said angrily.

If it is said that the sword is made by hand, it must be made by hand.

The task is under the leadership of the above, and he has nothing to do.

Besides, if it is really made by machine, it will be meaningless to the factory.

Zhang Ziqi smiled awkwardly, but didn't say much.

This is also the embarrassment of the ancient method of casting swords.

You have spent countless thoughts, it is better to come to high-tech casually.

Listening to the conversation between the two, Qin Luo smiled, waved his hands and said, "You don't need to read the sword casting log, but I probably know what's going on..."

"There is still one process missing here."

Ok?
Hearing this, Qin Guangrong immediately cheered up.

At this time, he suddenly saw that there were two old masters beside him. Hearing Qin Luo's words, he seemed a little annoyed and wanted to come and listen. Qin Guangrong immediately took Qin Luo's arm.

"Come on, let's go over there and talk."

Qin Luo was slightly stunned.

He glanced at him thoughtfully.

The mood is also a little delicate for a while.

This Qin Guangrong is really interesting.

I haven't learned it yet, and I'm already thinking about "preserving myself with a broom".

He has already regarded the secret recipe process that he has not yet said as his secret, and he does not want others to hear it.

However, such things as hiding one's hand are extremely common in the industry of traditional skills.

Qin Luo took a deep breath.

Originally, it didn't matter if I passed it on to them for free.

However, at this moment, seeing his behavior like this made Qin Luo feel a little out of sorts.

Why make him cheap for nothing?
"How about this, I'll make a sword, and everyone will take a look at it, that's fine."

With a thought in mind, Qin Luo said with a faint smile.

Qin Guangrong's eyes froze slightly, and he was about to say something...

But Zhang Ziqi was already chiming in on the sidelines: "Can you do it? Don't make a fool of yourself...you'll embarrass me when the time comes."

"Would you like him to try?"

On the surface, these words were teasing Qin Luo, but in fact, they were still running on Qin Guangrong.

Qin Guangrong was silent for a while.

After all, it is more important to complete the task.

Zhang Ziqi's face is not easy to refute.

So he smiled and agreed.

"Okay, of course it's fine."

"However, now? Should we drink tea, eat, and get ready?"

He still had the idea of ​​"let me enjoy the secret recipe" in his heart, to see if there was any room for discussion.

Qin Luo waved his hands and smiled.

"Just now."

In fact, it is very simple to solve the problem of uneven stress after quenching. It has been researched as early as the Spring and Autumn and Warring States Periods.

But, I don’t know why it’s still lost even now?

Now that I have caught up, let's take out this lost thing and show them.

I don't have any thoughts of self-preservation.

If everyone thinks this way, then any industry will be inferior to each other from generation to generation.

……

Qin Luo fumbled among a pile of sword embryos, and quickly found a half-finished sword blade.

After weighing it a few times, it feels very suitable.

An old master next to him, seeing Qin Luo's move, frowned slightly, but relaxed a little because of it, looked into the eyes of a master next to him, and nodded slightly.

After Qin Guangrong glanced at it, he couldn't help laughing and said, "Good eyesight."

A pile of sword embryos, some good and some bad, are all piled together and randomly selected.

But the one selected by Qin Luo is the best quality among them.

Just the eyesight of this selection, in fact, has already shown his hand.

It's quite convincing.

"Hammer!"

Standing in front of the workbench, Qin Luo glanced at Zhang Ziqi and said with a smile.

Zhang Ziqi: ...

"How big?"

Qin Luo pointed to the largest one next to it, which looked like a mountain hammer for digging rocks, at least fifty catties.

Zhang Ziqi rolled his eyes: "I can't handle it, I can handle it myself."

"Trash, what do you want?"

Qin Luo made a joke, but got up by himself and walked towards the hammer.

The shirt I'm wearing today.

Wielding a hammer is inconvenient.

So Qin Luo took it off casually, stripping off his upper body, revealing a particularly clear muscle outline.

After practicing Wu Qin Xi for so long, the lines of the body are much more beautiful.

A naked man, holding a huge hammer in his hand, this picture looks simple, rough, and sexy.

Sister Cha couldn't help but took out her phone and clicked to take a picture.

Then he said with a smile to Yang Zi next to him: "Sexy anchor, strike iron online..."

Yang Zi: ...

For a while, I couldn't help laughing.

This……

But Master's figure is pretty good, a bit sexy.

"I'm stupid, when did you get such a good figure?"

Zhang Ziqi let out a strange cry.

You can't tell without taking off your clothes.

Although it can be seen from the shape of his face that Qin Luo is quite thin, but after taking off his clothes, this muscle is really beautiful.

Qin Luo didn't even look at him...

when!
A hammer smashed down.

Start striking!
