Datang: I am the prince of salted fish, I impeach Li Er at the beginning

Chapter 155 It's a matter of course, on the right track

Listening to Zhanzhou's rambling introduction of the new ironmaking method.

Li Zhi always felt that something was not right.

Taking advantage of Zhanzhou's speech, he quickly interrupted and asked, "Have you never thought about using natural resources to turn the blower?"

Zhanzhou was taken aback, and asked, "Your Highness, what are you talking about...?"

"Water!" Li Zhizhi said naturally: "There is Qingming Canal in the Imperial City, and Weishui River outside Outer Guocheng. Why don't you try to use water power to drive the blower?"

"How to do this?" Zhanzhou asked in a daze, he really didn't know there was such a way of thinking.

Seeing this, Li Zhi said helplessly: "Didn't I give you a demonstration? The blower blows air through mechanical transmission. Can't we apply this transmission method to hydraulic power?"

After what he mentioned, Zhan Zhou opened his mouth and seemed to have realized something.

The old man hammered his palm, and suddenly realized: "Yes! You can use a water truck!"

The waterwheel was invented as early as the Eastern Han Dynasty, and the use of waterwheels in the Tang Dynasty was quite extensive.

Zhanzhou is old and his thinking is rigid. It's normal that he didn't think of this.

But hearing what Li Zhi said, his thoughts suddenly became clear, and he immediately understood what Li Zhi wanted to express.

"Huh~ His Highness is indeed a literary star. In our eyes, it seems like a huge problem, but His Highness easily solved it with just one sentence. This is really... shameful."

It is a problem that can be solved by changing the way of thinking, but with so many people in charge, no one has come up with a solution to the problem.

If one or two people don't figure it out, it may be their own problem.

If so many people can't think of a solution, it's possible that the other party has something special.

Zhanzhou took advantage of the situation and sent a flatterer, and attributed the problem to himself.

It not only complimented Li Zhi, but also left an impression that he had the courage to take responsibility without having to take the blame.

Simply perfect.

Li Zhi gave him a funny look, then shook his head slightly.

"It's not that this king is superior in intelligence, it's that everyone is content with the status quo. Since no one wants to change, naturally they can't think of a good idea to change the status quo."

Said lightly, Li Zhi looked at the furnace.

"Forget it, it's meaningless to say these things, let's see how the smelting works."

Zhanzhou smiled awkwardly, and said, "Don't worry, Your Highness, it has been tested many times, and there must be no problem in smelting iron ingots."

"Oh, all right."

Li Zhi responded casually, raised his neck and looked for a familiar figure in the crowd.

As soon as he turned his gaze, he saw Zuo Wenhao who was waiting.

Zhan Zhou seemed to have seen his intentions, and explained from the side: "Today's first batch of cast iron is for the Zuo school office. Zuo Wenhao once asked the officials to talk about it. Since it is His Highness's intention, we will As a supervisor, it is natural to pay attention to it.”

Hearing this, Li Zhi laughed dumbly: "Ah, Master Zhan still noticed it."

"Your Highness is here, besides the paper machine, why else?" Zhan Zhou joked and asked with a smile: "I heard that the machine made by Shi Lei has passed the test?"

"It's just the first test. It will take time to test before we know the final effect." Li Zhi replied calmly.

Zhanzhou nodded in agreement: "That's natural. Anything that hasn't passed the test of time cannot be called a finished product. I never thought that His Highness would make achievements along with the craftsmen."

Li Zhidao: "It's just a little bit of attention, it's too much to do."

"But I heard that the paper machine was also made by you."

Zhanzhou's eyes were smiling, and his eyes flickered a little, which seemed to be unclear.

Li Zhi shook his head, but did not continue the words.

Some things are destined to be unexplainable, so it's better to just avoid them.

Anyway, when the ancients faced incomprehensible situations, they had their own set of explanation methods.

Li Zhi didn't need to care, and he didn't need to explain these things to others.

After waiting quietly for a while, the furnace was opened under the operation of the craftsmen.

The moment the stove was turned on, a heat wave swept across the entire hall, raising the temperature in the hall by several degrees.

Looking inside along the open furnace, the red molten iron is trembling on the large disk.

I saw a craftsman holding a special tool in his hand, clamping something like a crucible, and scooped out a crucible of molten iron from it.

The thick arms were tense, and he lifted the crucible with great effort and ran to the side of the mold. The craftsman immediately poured the molten iron in the crucible into the mold, and the casting was considered complete.

"After pouring it in, it needs to cool down for half an hour before it can be considered fully formed. During this time, we can only wait patiently."

When the craftsman made this series of movements, Zhan Zhou explained.

Li Zhi nodded thoughtfully and asked casually: "Doesn't it need to be quenched?"

Zhan Zhou said: "In the past, forged ironware definitely needed to be quenched, but I don't know what's wrong with cast iron. No matter whether you use the quenching process or not, the strength of the final forged objects is not much worse than ordinary ironware. The strength is higher, and we don't know what this phenomenon is, but since it is the same whether it is quenched or not, it saves a process."

"Oh I got it."

Li Zhi suddenly realized, no wonder it is not quenched, it turns out that quenching is useless.

But what's the matter?

Does it make any difference whether it is quenched or not?
I haven't learned it, and I don't understand it.

Seeing this, I have finished watching the smelting process.

Li Zhi greeted Zhanzhou and walked towards Zuo Wenhao.

Looking at the ceramic mold that was still heating up on the ground, Li Zhi asked him: "Is this the hammer head that was cast? Is this the last piece of the puzzle?"

"Attach the hammer head and cover it with the hide, and the masher is complete."

Zuo Wenhao saluted and said: "But I heard that after the installation is completed, it will be tested, and the modification will continue based on the test results."

"Yes!" Li Zhi nodded and answered, "No matter how good something is, it must be suitable for the place. If there is a problem, not only the details need to be modified, but even the materials used to make the machine must be improved, and manufactured according to the specifications on the drawing. , it can only be used in theory, and it depends on the actual situation.”

The drawings given by the system did not indicate what kind of material was used, but what is certain is that it is definitely not made of pure wood.

And even if wood is used, there are many types of wood.

Changes are definitely necessary. The problem is to find out the disadvantages in actual use first.

If no disadvantages can be found, then there is no need to modify it, but this is obviously unlikely.

"So, you have to go to Shi Lei and go with him to the paper factory outside the city for a test. He will arrange the test for you."
