Poor family mother and son

Chapter 54 Saving the vocal cords
Just now when Zhang Mingyu turned around, Hong Liang turned his head inadvertently, and saw the big knife behind Zhang Mingyu.Shiny and reflective!

"Ah..." Zhang Mingyu suddenly didn't want to respect this second-rank official.The sudden brake made Zhang Mingyu almost incontinent!
"Your saber..." Before Hong Liang finished speaking, Zhang Mingyu untied his straps and presented the pair of sabers: "My lord, please watch first, the villain is anxious... I can't hold it back!" Before Hong Liang finished speaking Allowed, turn around and run away.

When Zhang Mingyu came back, he saw Hong Liang in the yard in front of the hall, holding two ghost-headed knives and dancing like a tiger and a tiger.Chu Qing and Mrs. Hong stood on the porch and watched with smiles.

Zhang Mingyu felt a little regretful, he shouldn't have given the knife to Hong Liang, he was playing with the knife endlessly, what if he didn't give it back to him?
"Boy! You have a pretty good knife! Where did you get it?" Hong Liang accepted and asked Zhang Mingyu.

"Miss Chu gave it to you." Zhang Mingyu replied honestly, feeling uneasy in his heart: Don't ask for it!
"Oh?" Hong Liang turned to Mrs. Chu again.

If this person has a high official rank, he should be sparing in speaking. The full text of the "Oh?" should be like this: "Ms. Chu, where did you get this knife?"
"Master Hong, this is a blast furnace built by our Baolu Group. It was made by smelting some waste hoes." Chu Qing replied.

"Oh?" Hong Liang came again.

The meaning of this "oh" is probably to ask - can you still smelt iron?

"Hehe, I'm just idle and have nothing to do." Chu Qing answered casually.In fact, she also wanted to save her vocal cords and answer "Yeah!"

But no, we brought Zhang Mingyu here to make a confession, isn't it just to hope that this official university can get some iron ore out of it.Otherwise, why are you in such a hurry to send a bank note.

"If Mrs. Chu has time, can I get a pair for this old man? If not, then..." Hong Liang turned his gaze to Zhang Mingyu.Zhang Mingyu sweated instantly, and looked at Chu Qing for help.

"Master Hong, this is our test product." After receiving Zhang Mingyu's signal, Chu Qing explained, "We don't have materials to refine, and these are scraps of copper and iron made together, so the quality of the iron produced is not good. Not very good."

"Well, it's very good. I tried it on a tree just now, and the blade was not damaged." Hong Liang said, looking to the side, where a plum tree as thick as an adult's arm was cut in half.Zhang Mingyu stared at the big knife in Hong Liang's hand with a distressed face.

"It would be great if there was pig iron or iron ore. We use old hoes and iron pots to smelt it. I'm afraid the impurities in it can't be removed completely." Chu Qing explained again.It doesn't matter whether it is cleaned or not, anyway, it can't be cleaned, otherwise Zhang Mingyu will cry.

"That's it..." Hong Liang reluctantly returned the two knives to Zhang Mingyu. Zhang Mingyu took them and held them in his arms, then ran to stand beside Chu Qing.I didn't bother to put the strap on my back first.

No matter how old a man is, he is relatively immature in front of the weapon in his hand.

"Iron ore is easy to get!" Hong Liang said: "I'll get you some, just say that I want to improve weapons and get some iron ore for experiments."

Sometimes what you think is difficult is actually just a matter of one sentence in the eyes of powerful people.Chu Qing felt that today's offering was not in vain, and that there would be room for ore in the future.

The ore was quickly sent to Baolu Group.Not many, but there are twenty cars.Enough for Chu Qing to study.Chu Qing did not start work easily.While ordering to continue washing coal and making coke, she began to design drawings.

Previously, Chu Qing had a preliminary idea about the time-consuming process of forging iron.The purpose of forging iron is to adjust the carbon content to an appropriate level, so isn't modern steelmaking the purpose?

Modern steelmaking has mature technology, and steel products can be mass-produced with molds.The industrial level of this era has not yet reached.But Chu clearly remembered that there was a European named Bessemer who invented the converter technology, which made it easier to remove the carbon in molten iron.

It is said that when Bessemer used a crucible to smelt iron, he accidentally found a piece of iron sticking to the side of the crucible.

He observed carefully and found that it was a tempered steel sheet.How did it become a sheet of steel?After a long period of thinking and experimenting, he finally figured out the reason: the carbon in the pig iron was oxidized and turned into steel because of the oxygen blown in.

There is no oxygen, but we can blow air.Once the blueprints are drawn, construction begins.Because Master Lu can't understand the design on the drawing, he can't give a reference.

Chu Qing used the materials used to make refractory bricks to fire a converter like a pickle jar.And a batch of refractory brick boxes without lids.And opened six tuyeres at the bottom of the converter.

A ditch was dug on the ground below the blast furnace taphole, and the inner wall was smoothed and sealed with refractory bricks and kaolin mud, which was used to introduce the smelted molten iron into the converter.In this way, the blast furnace and converter form a continuously operating system.

After half a month of design and production, today is finally the time to test the results.When the finely crushed iron ore turns into molten iron and enters the converter through the pipeline, the bellows responsible for heating the air also start to work.

With the experience of ironmaking last time, they are responsible for a series of operations such as feeding, filling, slag digging, and bellows, and everyone cooperates in an orderly manner.

This time the work of the converter was added.When all the molten iron is injected into the converter, the six tuyeres blow air into it at the same time, and the impurities in the molten iron are oxidized and ejected instantly, and the temperature of the molten iron rises. The scene is like a volcanic eruption!
The workers ran away in fright, shouting "It's going to explode! It's going to explode".On the contrary, the servants and long-term workers of the family were still standing there.

When the "volcano" gradually extinguished, Chu Qing shouted: "Fall!" The servants pulled the chain on the mouth of the converter one after another, tilted the furnace body, and the molten iron inside, now molten steel, poured out.

The bottom is a refractory brick box. When a box is full, someone will pick it up with a hoe. The rolls made of kaolin mud under the box make it easier to transport the box.

When the molten steel cooled down, Master Lu came over to check.He tried to forge this new piece of iron, and found that it was steel!It's real steel!This is steel that can be used for direct modeling!
There is not much steel in this furnace, because it is an experiment, so Chu Qing did not dare to use more iron ore.But for these steels, Chu Qing also gave Hong Liang a saber.

This saber was designed by Chu Qing, I don't know if it is reasonable or not, anyway, I think that big and tall Hong Liang should look good with it.

The blade is about seventy centimeters long, and the handle is about forty centimeters long.The arc-shaped blade is narrow, long and thick, and the blade is extremely sharp.The handle of the knife is wrapped with a leather rope, and Master Lu specially wrapped a layer of red copper for decoration on the collar part.

Oops, it's so pretty!Chu Qing couldn't bear to give it away!Master Lu's craftsmanship is really good!The spirit of excellence of ancient craftsmen is really worth learning.

Anyway, the steel was still enough, and Chu Qing asked Master Lu to make a combined eight-sided spear, which was completely a design that Chu Qing took for granted.Because she is not sure whether the combined interface can live up to her imagination.

But who is Master Lu? He is a great craftsman who has spent half his life in the Ministry of Industry!Chu Qing's request, Master Lu has been researching day and night, so he has to figure it out!
For Master Lu, he is also working for others. In the Ministry of Industry, Master Lu is used as a machine, and he can only do things according to the requirements, and cannot have his own creativity.But here at Chuqing, the salary is slightly higher than that of the Ministry of Industry, and he is respected, and Chuqing asks him for advice, not orders.

Chu Qing's design will also inspire him to increase his own innovation while meeting the requirements. The cooperation between the old and the young is a tacit understanding.

The most important point is that this steel is good!If there are good materials to use, for Master Lu, that is the feel!Feel good, confidence is enough.

By the time even the combined eight-sided spear was ready, another half month had passed.Chu Yuanlai reported that there were three eyeliners in the mine, two in the mine, and one who was in charge of supervising the repair of the mountain road.Nothing wrong has been found so far.

After explaining the serious matter, Chu Qing took Chu Yuan to the courtyard and showed him the spear.Chu Yuan hadn't come to the yard on the reception hall for a while, and was busy with running errands outside. When he saw the spear suddenly, he thought someone had forgotten the weapon here.

"It's for you, try it." Chu Qing said.

"But I won't make..." Chu Yuan felt ashamed.
