The young craftsman secretly made up his mind.

Since he was a child, he learned to make various crying machines with his father, and he is passionate about this industry.

It is a great honor for him to participate in such a far-reaching project.

After a long period of hard work, the craftsmen finally succeeded in producing a large, precision-meshing main drive gear set.

Seeing the two large gears rotating in perfect harmony, all the craftsmen involved in the production couldn't help but be excited.

"Thanks to the guidance of the prince, we have finally overcome this problem!" The young craftsman said excitedly: "We will keep in mind the teachings of the prince, continue to improve all production links, and strive to achieve the best quality of each part!" ”

After Chu Ze and the craftsmen solved the technical problems in the boiler and transmission system, they happily began to study and trial produce the key component of the cylinder.

This was crucial to the success of the steam engine.

"Come on, let's come and discuss, how to make the cylinder to withstand the steam impact of high temperature and high pressure?" Chu Ze beckoned to all the craftsmen, while drawing and designing the shape of the cylinder on the paper.

All the craftsmen came together, and you put forward your own opinions word by word:

"I think ordinary cast iron should be fine, and besides, what more advanced materials do we have?"

"But I'm worried that the strength of the pure cast iron is not enough, and if it is blown up, the impact will be too bad!"

"Hmm...... Also, this cylinder has to withstand a lot of pressure, and the material has to be too hard. ”

"So what kind of material is good? This stumped me......"

The craftsmen fell into deep thought, and this was indeed a difficult problem.

The cylinder is the heart of the steam engine and must be strong enough.

But their existing casting technology seems to struggle to do so.

Chu Ze also frowned, it was indeed difficult to choose the right cylinder material.

If ordinary cast iron were to be used, it would be difficult to make a large cylinder that was strong enough with the current casting technology.

How can this be?

"Ahem, guys." At this moment, a young craftsman suddenly spoke, "I may have an idea here. Maybe we can try the method of forging iron to make cylinders? ”

"Huh? With forging? Everyone was stunned for a moment, and they all looked at the young man who suddenly proposed.

"Yes, I think forging can improve the strength of the cylinder." The young craftsman explained: "Repeated hammering makes the metal denser, so that the large forgings can withstand the steam pressure. I've recently developed a new type of forging hammer that works very well, maybe I can try it? ”

"Hmm...... Reasonable! Chu Ze's eyes lit up when he heard this, and he patted the young craftsman on the shoulder vigorously and said, "Good idea!" Tell us about this new forging method you've researched and see how it works. If you succeed in making large forgings of excellent quality, the problem of cylinders will be solved! ”

"Obey the king!" The young craftsman, who had been affirmed by Chu Ze, suddenly increased his confidence, and after arching his hands and greeting everyone, he walked to the anvil and began to prepare to demonstrate his new forging technique.

The other craftsmen followed with great interest, to see what new tricks the lad could come up with.

The young craftsman first heated a piece of pig iron with coals until it turned red, and then took a huge hammer that was unusual and aimed at the iron and struck it violently.

He could only hear the sound of "clanging", and he raised and fell with his hammer, aiming at different parts quickly and powerfully, and splashed a spark when he struck each hammer.

The other craftsmen looked at it intently, they had never seen this kind of beating, and they could see that the young man's technique was quite skillful, and he was not aimless.

"This young man's hammering method is very particular, and the strength and frequency are well controlled."

"Yes, and I also beat different parts of the iron, which is bound to make the metal harder more evenly."

"Well, this new forging method is really ingenious, and the effect is definitely much better than our existing forging."

The craftsmen whispered to each other, all praising this novel forging technique.

After a few hundred strokes, the rough cast iron became denser and stronger, and the surface became smoother and brighter.

The young craftsman brought the forged iron and handed it to the others for inspection.

"Wow! The forging effect is truly amazing! The old craftsman held it in his hand and looked at it carefully, and struck it a few times, making a crisp metal impact sound: "Being hammered like this, the density inside the iron block has been significantly improved, and the feel is much harder!" ”

"Yes, yes, I see it that way." Other craftsmen were also amazed: "This repeated forging can effectively eliminate the stomatal relaxation inside the cast iron and greatly enhance its strength." It seems that it is feasible to make cylinders this way! ”

"Great, I knew we could count on you!" Chu Ze said happily and loudly, patting the young craftsman on the shoulder again.

The young craftsman couldn't help but feel a little embarrassed when he received the praise from everyone, and he was very pleased that his new forging method had been recognized by so many people.

"Thank you, elders, for your awards. It's not a small improvement, but if I can help make a better cylinder, that's my greatest honor. ”

"Okay, okay, don't be modest!" Chu Ze said encouragingly: "Your new forging method is obviously a great innovation!" I think you are the 'forging expert' of this project, and with you in charge, the quality of the cylinder will definitely be fine." Everyone should learn more from him! ”

"Yes! Obey the king's orders! After being promoted and affirmed so vigorously by Chu Ze, the young craftsman's enthusiasm boiled, and his confidence also increased greatly.

He is determined to take this new forging technology to the extreme and ensure that the cylinder can be successfully made!

Under the careful guidance of the young craftsmen, everyone quickly mastered the know-how and essentials of this new forging method.

In the days that followed, the forging room was blazing, and the craftsmen were beating me and making the forgings needed for the cylinders with all their might.

The hard work soon paid off.

Just a few days later, the first large cylinder forging was made, and it came out of the oven with a striking sheen and a sturdy look.

The old craftsman knocked on it, and there was a crisp sound of gold and iron, which showed that this oversized forging had reached an extremely high density.

"Excellent! This cylinder is of impeccable quality and can definitely withstand high pressures with ease. Chu Ze looked at the forging and admired it sincerely.

"Thank you for your advice, we will continue to work hard to make the highest quality cylinder!" The craftsmen were very excited.

Under the careful guidance of the prince and this young man, they finally took such a crucial big step. (End of chapter)
