Chapter 290 Suggestions

Su You looked at the raw coal for iron-making: "Why not use coking coal?"

The great master asked: "What is coking coal?"

Su You said: "Raw coal has extremely heavy sulfur gas. Is the steel produced from it really suitable?"

The great master said: "This... is naturally not possible, and pine charcoal must be added to mix it."

Su You nodded and looked at the blast furnace again: "If the cold air goes in, can the furnace temperature be guaranteed?"

The master craftsman was a little confused: "Well, it's not enough to let in too much wind at one time. Wind control is also a skill."

Su You said: "Then let me see the steel you made."

The great master no longer dared to be proud: "Shangguan, please come this way."

Isn't this little official a Tanhualang? How come he is born as a technical officer? He only asks some professional questions, but if he has the ability to ask you, he has the ability to solve them.

After muttering all the way to the iron materials, the master pointed at Su You and said, "That's it."

Su You took it out and looked at it. The color had not turned green, which was very different from the steel from the Erlin Department.

He took out the folding knife from his schoolbag, pressed it open, and chopped it against the edge of the iron material.

A small hole suddenly appeared on the edge of the iron material.

The accompanying group of craftsmen were all dumbfounded. They only heard that Meishan’s folding knives were unparalleled in the world. They always thought it was a fabrication of literati. After all, no one had the chance to see it. It turned out to be true!

Su You bent down and inspected the chop carefully. He stood up and saw a group of craftsmen with glaring eyes. He handed the folding knife to the master craftsman and said, "Let everyone take a look. It's not a strange thing."

The master craftsman held it in both hands: "This is not a rare thing, this is really a magic weapon."

Su You read it over and had a rough idea: "To produce good steel in this furnace, pine charcoal is the most important. The temperature of the pine charcoal is not enough, so you added coal to it, but the coal brings another problem: the sulfur gas is too heavy, so

The quality of the molten steel is a bit worse, right?”

The great master no longer dared to look down upon Su You, and handed the folding knife back to Su You: "I heard that the official is from Meishan?"

Su You smiled and said: "Yes, Meishan people, Meishan Metallurgy, starting from mineral processing, they also use coal, but the method is unique, so the quality of the steel produced is no less than that of Xixia Qingfeng."

"But if you want to exceed it, there is no way. You have to use Dali iron as the main material."

The master raised his hands and said, "I don't know what method?"

Su You said: "It is not convenient to go into details about the method here. We will have plenty of time to talk about it in the future. However, your craftsmanship is very good. It is a great achievement to be able to produce so much molten iron in one furnace. It is not possible in Meishan. In many places, only

It needs some improvement, and the quality of molten steel will be improved by more than one level."

The master didn't believe it, but the steel quality of this kid's folding knife was really different from his own. This was also true, and he couldn't help but feel a little bit stunned.

Su You smiled and said, "I'll just give you a simple example."

After speaking, he pointed at the bellows, "If the cold air is replaced by hot air, how much will the furnace temperature increase?"

A flash of lightning flashed through Dajiangzuo's mind.

Su You smiled slightly at the master craftsman, cupped his hands and said, "So everyone, your opportunity has come to make contributions to the imperial court."

Before the master could become happy, Su You said: "But these are things for later. Let's take a look at everyone's food first."

Of course, Su You couldn't be satisfied with the food at Zhou'an Iron Works. The boy dug a hole for himself, and now he set an example by eating brown rice with the craftsmen.

As for the vegetables, they are actually boiled leaves in water, but some workers bring their own oil cans and mix some oil residue into the rice, which is considered as adding meat.

Su You almost burst into tears: "Who has some oil residue to lend me? I forgot to bring it with me today. I will return it to you tomorrow..."

The master was speechless: "You nobles shouldn't insist on eating with us. Isn't this a sin! Li Er! Why are you hiding the soy sauce that your wife prepared for you? Hurry up and bring it to the official!"

Li Er brought the jar over in distress: "My wife wants me to save some food..."

Su You directly put a small jar of noodles with soy sauce into his bowl. After mixing it, he took a bite and expressed his satisfaction: "Li Er, your wife's skill at making soy sauce is pretty good! Why don't you call me to cook for everyone tomorrow?"

The secretary can still give me this little face."

Li Erzheng was heartbroken for Xiangzi, and he was overjoyed when he heard this: "Okay! I asked her to come early tomorrow morning, Xiao Guanren, aren't you just making fun of me?"

Su You said: "If you are called over tomorrow, I will go and talk to the secretary in charge now!"

After looking at the blast furnace, Su You took Hong Jiang to see him again.

He took out a drawing and said: "Brother, you are also an old man in the case. Take a look at this."

Hong Jiang was stunned, why, you are not here for dinner this time?

When I saw the drawings, I was suddenly surprised: "Is this a furnace?"

Su You said: "This is a set, not only a smelting furnace, but also a coke oven."

Hong Jiang raised his hand: "Brother, wait a minute, don't say anything yet. I'll see if I can understand it first."

After an hour passed, Hong Jiang looked up again and saw Su You slowly playing the tea ceremony.

Hong Jiang said: "I am confident that I understand half of it!"

Su You smiled and said: "Which half?"

Hong Jiang pointed at the blueprint of the furnace with his finger: "The half that raises the furnace temperature! Where did you get this blueprint? Hi! You are the son-in-law of the Shi family. How come I forgot about this..."

After saying that, he tutted repeatedly: "The Shi family even took out such important things for the sake of my brother's future..."

Huh? Brother Hong, you have a very smart mind.

Su You cupped his hands and said: "Shi Tong Shi Dazhi, a descendant of Shijia Meishan, is now in Zhengzhou. What I mean is that since the big furnace of the Zhou Case has to stop work and cease fire, it is better to summon him to transform the big furnace and improve it."

I wonder if it’s possible to improve the quality of steel?”

Hong Jiang said: "I looked at the drawings and it doesn't take much time to modify the air box, but why does the heating pipe have to be so complicated?"

Su You said: "Because this is not only a heating furnace, it is also a coke oven."

"Oh?" Hong Jiang asked: "The Shi family's secret method of charcoal making?"

Su You was shocked: "Brother, you actually know this?"

Hong Jiang said proudly: "I am still more concerned about metallurgical technology. The Shi family smelted iron in Meishan and used coal! I ordered the craftsmen to try one furnace, but the effect was not effective. Later, I switched to using raw coal and pine charcoal to combine, and finally managed to

Worthy of use."

After speaking, he clicked on the drawing: "At that time, I was thinking, either the raw coal origin is different and the physical properties are different; or the Shi family has a special method to make the raw coal usable..."

"As soon as I saw your complicated drawing, I knew it must be the latter!"

Su You cupped his hands and said: "The Shi family is willing to offer this method to the imperial court to help the country. I wonder if Brother Hong agrees?"

Hong Jiang sighed: "Brother, you are too flattering. With the Shi family's reputation in the army, and your reputation with Zhao Deputy Envoy and Gao Case Judge, how can I, Old Hong, have any say?"

Su You said: "This is a national matter, and you are my superior. If I have any suggestions, I must first report them to you, the Secretary-General. As for the judgment of Gao's case, Deputy Ambassador Zhao should report it to the Secretary-General step by step. I

At most, I can help from the side, this is the system."

Hong Jiang looked at Su You: "Brother, what can I say about you? You are still so honest... What else is there to say about this matter? Military merit, brother!"

Su You smiled and said: "As long as I agree, then I'll go up and play the drums! Are you all hungry? I'll greet you and serve the food!"

"On Renzishuo in the sixth month, the sun has an eclipse. At the beginning of the month, Si Tian said that half of the sixth part should be eclipsed. At the beginning of the day, four points of the eclipse started from the west, and there were clouds, thunder and lightning, and a sudden rain. The armillary sphere said that it would not be a disaster.

"

This solar eclipse was very funny. Si Tianjian calculated that the eclipse would be six and one-half times partial. However, when the eclipse reached the fourth eclipse, suddenly clouds came over and blocked the sun, followed by a heavy rain. After the heavy rain, the sun returned to normal.

.

Then, the daily fight began.

The prime ministers gathered together to congratulate: Your Majesty, we have won. Your kindness will make even the sun give face to you...

Quan Yushi Zhongcheng jumped out, saying this is wrong and inaccurate! By doing this, the official family has lost its intention to only fear heaven!

The fact that the solar eclipse was blocked by clouds does not mean that it was not a total eclipse! It just means that no one can see it! This is an anomaly, not His Majesty's fault!

Your Majesty, you sincerely cultivate your virtue, and you will be moved by the changes in your answers, but you certainly don’t think this is a good omen, right?
