Chapter 407

"Pry it for me!"

As soon as the voice fell, Su Mo's just raised arm also fell heavily.

"Boom!"

"Boom!"

"Boom!"

The three cranes started instantly and made a roar. The steel rope tied to the solid steel column collapsed straight under stress.

Click——

With a loud piercing noise, the solid steel column inserted on the ground was broken.

At this scene, Su Mo's eyes jumped, which he never thought of. According to his calculation, this solid steel column can support the task of prying the imperial tower.

How could it break?

The three workers who operated the Crane quickly closed the crane and looked at Su Mo at a loss.

"Su Mo, what's the situation?"

The chief construction engineer stared at the broken steel column with a trace of surprise in his voice.

Su Mo frowned deeply, which was really beyond his expectation.

"It seems that the imperial tower is heavier than I thought!"

According to Su Mo's calculation, this will not happen at all. However, the steel column is indeed broken, so there is only one reason, that is, the weight of the imperial tower is far beyond Su Mo's estimation.

Su Mo turned to look at the chief construction engineer and asked in a deep voice, "what material is this steel column?"

"Ah!"

"No wonder."

Su Mo nodded, then took out a paper and pen and lay on the ground to calculate.

"Chemical composition of refined steel"

C≤0.03Si≤1.00Mn≤2.00P≤0.035S≤0.03Ni:10.0-14.0Cr:16.0-18.0Mo:2.0-3.0

The chief construction engineer swallowed his saliva and carefully asked old Chen, "old Chen, what is Su Mo doing?"

"Where do I know?"

Old Chen stared angrily. How can he understand this

They stood beside Su Mo honestly, all keeping silent, afraid to disturb Su mo.

A piece of white paper was soon filled with dense information. Finally, Su Mo's eyes lit up and wrote down a number.

“8.8！”

Su Mo stood up excitedly and handed the white paper to the chief construction engineer.

"According to this piece of paper, make a steel column with the same size and length as this steel column!"

As he spoke, Su Mo pointed to the solid steel column broken into two sections.

"What is this?"

The chief construction engineer took the draft paper handed by Su Mo and looked at it for a while, just like reading a book from heaven.

"Su Mo, what do you write on this paper?"

Chen Lao also looked at Su Mo in a fog. He couldn't understand the content on the paper at all.

In the face of their inquiry, Su Mo slowly explained: "this is a steel forging method. At present, the density of cast steel is about 7.8, but this steel forging method can make the density of cast steel reach 8.8!"

"At present, the density of the best 100 steelmaking in China is only 8.3. However, according to my calculation, 100 steelmaking may not be able to support the imperial tower, so I temporarily invented a new steel forging method."

Old Chen: "

Chief Construction Engineer: "..."

Can it still be like this?

A new steel forging method was invented temporarily?

Are you kidding?

This is steel forging!

Every steel forging method is slowly explored through countless experiments. Can this thing be invented temporarily?

Cough——

Old general Chen Xin Jiang looked suspiciously at Su Mo and asked in a trembling voice, "is this really a better forging method than 100 steelmaking?"

"Of course!"

Su Mo smiled confidently. If the density of steel can be increased by 0.1, the quality will be more than doubled.

Moreover, according to his calculation, the density of refined steel produced by his forging method is fully increased by 0.5 compared with 100 steelmaking.

What is the concept of 0.5?

Let's just say that if the density is increased by 0.5, the quality can be increased by at least eight times!

That's eight times as much!

Old Chen trembled. He was in an important position, so he could better understand how important this cast steel method was. If it was like what Su Mo said, then this humble draft paper is absolutely priceless!

You know, no matter what core parts are, there is no shortage of 100 steelmaking, because 100 steelmaking is limited by quality, and many places are replaced by alloys. If we can really make refined steel with higher quality than hundred steelmaking, the industrial level of Xia country can be improved to at least one level! Xia's current industrial level is already a first-class level in the world. If it is upgraded to another level, Xia's industrial level will definitely become the first industrial power in the world“ Give me the paper. " Old Chen's voice is low and dull. Now he only feels his throat dry, which is caused by extreme excitement. He took the manuscript paper from the chief construction engineer and carefully put it into the pocket of his coat, just like a peerless treasure. Cough - "that Su Mo, is the imperial tower safe now?" Old Chen asked“ Yes. " Su Mo nodded and said, "it's just that if it tilts for a long time, it will lead to the structural deformation of the imperial tower, which will be more difficult at that time."“ Therefore, at present, it is best to restore the angle of the imperial tower to normal! " Although Su Mo didn't know why old Chen asked so suddenly, she said all she knew“ As long as it's all right for the time being, your steel forging method is very important. I must hurry to confirm it. Let's do it today. " With that, old man Chen left without returning. Su Mo was confused. What's the matter? He came up with this steel forging method to pry the imperial Tower! In Su Mo's opinion, it is completely avoiding the important and taking the light! However, if Chen knew his idea, he would scold. evade the crucial point? You're kidding! It's true that the imperial tower is very important, but this steel forging method is more important than the imperial Tower! In old Chen's mind, as long as this steel forging method is as powerful as Su Mo said, not to mention an imperial capital tower, even ten hundred towers can't compare with this steel forging method! Old Chen left like this, leaving a group of people staring“ Su Mo, what shall we do now? " Unconsciously, the chief construction engineer has regarded Su Mo as the backbone“ How do I know what to do? " Su Mo spread his hand with a bitter smile and said, "it seems that I have nothing to do for the time being. As for you, I'd better ask." With that, Su Mo turned and left. Only the chief construction engineer was left in a daze... As soon as Su Mo came, Chen Daoming and Li Renhui surrounded him. As for Yan Jiuxi, he had already jumped into Su Mo's arms“ Girl, there are people here. Do you want to reward me with a loving kiss? "
