Chapter 290 Advice

Su You looked at the raw coal used for ironmaking: "Why don't you use coking coal?" ”

The master craftsman asked, "What is coking coal?" ”

Su You said: "The raw coal and sulfur gas are extremely heavy, and the steel smelted is really suitable? ”

The master craftsman said, "This ...... Naturally, it is not possible, and it is necessary to add pine charcoal to mix. ”

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

The master craftsman was a little confused: "This, it is not possible to enter too much wind at a time, and wind control is also a craft." ”

Su You said: "Then let me see the steel you have refined." ”

The master craftsman didn't dare to be complacent: "Shangguan here, please." ”

Isn't this little official Tanhualang? How can you be like a technical officer, ask some professional questions, and have the ability to ask you, but you have the ability to solve it.

Coming all the way to the side of the iron material, the master craftsman pointed to Su You and said, "That's it." ”

Su You took a look at it, and the color did not return to green, which was very different from the steel of the second forest.

He took out the folding knife from his school bag, flicked it open, and chopped it against the edge of the iron.

A small opening suddenly appeared on the edge of the iron.

The group of craftsmen who accompanied them were stupid, only heard that the Meishan folding knife was unparalleled in the world, and I always thought it was a fabrication of the literati, after all, no one had the opportunity to see it, it turned out to be true!

Su You bent down to carefully inspect the chopping, got up and saw a group of craftsmen with burning eyes, and handed the folding knife to the master craftsman: "Let's show everyone it, it's not an uncommon thing." ”

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

Su You read it and roughly knew it in his heart: "This furnace wants to produce good steel, pine charcoal is the most important, the temperature of pine charcoal is insufficient, so you added coal to it, but coal brings a problem - the sulfur is too heavy, so the quality of the molten steel is a little worse, right?" ”

The master craftsman no longer dared to despise Su You, and handed the folding knife back to Su You: "I heard that the little official is from Meishan?" ”

Su You said with a smile: "Yes, Meishan people, Meishan Metallurgy, from the beginning of mineral processing, they also use coal, but the method is unique, so the quality of the steel smelted is no less than that of Xixia Qingfeng." ”

"But if you want to exceed, there is no way, you have to Dali iron as the main ingredient."

The master craftsman arched his hand and said, "I don't know what method it is?" ”

Su You said: "It's not convenient to talk about the method here, we will have time to talk about this in the future." However, your craftsmanship is very good, and it is a great achievement to be able to produce so much molten iron in one furnace, which Meishan can't do. In many places, only a little improvement is needed, and the quality of molten steel will be improved by more than one grade. ”

The master made some unbelief, but the steel quality of this baby's folding knife is too different from his own, which is also a fact, and he can't help but be a little stunned.

Su You smiled: "I'll just say a simple example. ”

After saying that, he pointed to the bellows - "If you change the cold air to hot gas, how much will the furnace temperature increase?" ”

The master craftsman's mind couldn't help but flash like a flash of lightning.

Su You smiled at the master craftsman and arched his hand: "So everyone, your opportunity to make meritorious contributions to the imperial court has arrived." ”

Before the master craftsman could get happy, Su You said: "But these are all afterthoughts, let's take a look at everyone's food first." ”

Of course, it is impossible to satisfy Su You with the food in the iron workshop, this baby dug a pit for herself, and now she is leading by example and accompanying the craftsmen to eat brown rice.

As for vegetables and vegetables, in fact, they are boiled leaves, but some of the workers bring their own oil cans and mix some oil residue into the rice, even if they add meat.

Su You's tears were about to fall: "Who has oil residue to lend me a little?" I forgot to bring it today, and I will return it to you tomorrow ......"

The master craftsman was a little speechless: "The noble person shouldn't insist on eating with us, isn't this a sin!" Li Er! What are you doing with the noodle sauce that your Hun family has rectified for you? Hurry up and bring it to the little official! ”

Li Er took the jar very distressedly: "My daughter-in-law wants me to save some food......"

Su You directly put a small jar of noodle sauce into his bowl, and after mixing, he took a bite and expressed his satisfaction: "Li Er, your Hun's skills in making noodles are good!" Why don't you call someone to cook for you tomorrow? The secretary can still give me this little face. ”

Li Erzheng was heartbroken for Zhenzi, and was overjoyed when he heard it: "Okay! I'll ask her to come early tomorrow morning - you won't be making fun of me, will you, little official? ”

Su You said: "I'm really calling me tomorrow, I'll go talk to the secretary now!" ”

After watching the blast furnace, Su You took Hongjiang to Fang Zhiwei again.

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

Hong Jiang was stunned, why, didn't he come to eat this time?

When I looked at the drawings, I was suddenly surprised: "This is - smelting furnace?" ”

Su You said: "This is a set, not all smelting furnaces, but also coke ovens. ”

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

It wasn't until an hour had passed that Hong Jiang looked up again, but saw Su You playing the tea ceremony slowly.

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

Su You smiled: "Which half? ”

Hong Jiang pointed his finger at the drawing of the smelting furnace: "The half that raises the furnace temperature!" Where did this drawing come from? Hi! You are the son-in-law of the Shi family, how did I forget this stubble......"

After speaking, he sighed repeatedly: "The Shi family even took out such an important thing for the sake of my brother's future......

Belch? Brother Hong, you have a very smart brain.

Su You arched his hand and said: "A descendant of Shijia Meishan, Shitong Shi Dazhi, is now in Zhengzhou, I mean that since the furnace is going to stop work and stop fire, it is better to summon it, transform the furnace, improve the quality of steel, I don't know if it is feasible for my brother?" ”

Hong Jiang said: "I looked at the drawings, and it didn't take much work to renovate the bellows, but why did the way of heating the air pipe have to be so complicated? ”

"Because it's not just a heating furnace, it's also a coke oven," Su said. ”

"Oh?" Hong Jiang asked, "The Shi family's secret method of charcoal?" ”

Su You was shocked instead: "Brother actually knows this? ”

Hong Jiang was proud: "I still care more about metallurgical technology, the Shi family smelts iron in Meishan, and uses coal!" I ordered the craftsmen to try a furnace, but the effect was not good, and then I switched to the combination of raw coal and pine charcoal, and it was barely usable. ”

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

"As soon as I look at your complicated drawings, I know it must be the latter!"

Su You arched his hand and said: "This Fa Shi family is willing to sacrifice to the imperial court to help the country, I don't know if Brother Hong agrees?" ”

Hong Jiang sighed: "Brother, you are too high-spirited, with the face of the Shi family in the army, with your face in the Zhao deputy envoy and the high case judgment, where is my Lao Hong's share?" ”

Su You said: "This is a major national matter, you are my boss, if I have any suggestions, I must first inform the secretary in charge, as for the high case verdict, Deputy Envoy Zhao should also be reported by the secretary in charge layer by layer, I will assist at most, this is the system." ”

Hong Jiang looked at Su You: "Brother, you ...... Tell me what is good about you? Still so honest...... What else is there to say about this? Military merit, brother!"

Su You smiled: "It's good that my brother agrees, then I'll go up and beat the side drum next!" You're all starving, aren't you? I'm going to greet the food! ”

……

"In June, there is an eclipse of the sun. At the beginning, Si Tianyan should eat half of the food. It was the beginning of the day, and the clouds were cloudy, thunder and lightning, and it rained. What the armillary sphere says is not a disaster. ”

This solar eclipse is very funny, Si Tianjian calculated that it would be six and a half of the eclipse, but the solar eclipse was only four minutes, and suddenly it was overcast, blocking the sun, and then a heavy rain. Wait until the heavy rain has passed, and the sun returns to normal.

So, the tearing daily began.

Zaichen gathered to congratulate: Your Majesty, we have won, your benevolence, let the sun give face......

Quan Yushi jumped out, it's not right to say this, it's inaccurate! By doing this, you have made the officials lose their fear of the will of heaven!

Just because a solar eclipse is blocked by clouds doesn't mean it's not eclipsized! It's just that everyone can't see it! This is the reason for the difference, not His Majesty!

Your Majesty, you are sincere in cultivating virtue and answering the heavens, but you will definitely not think that this is a good omen, right?

The official said that he was very congested and speechless, and you finished speaking, what else can I say?
