Becoming a stepmother of three children gives me space

Chapter 211: Qin Wangwei, blast furnace steelmaking

Heipao left Prince Qing's Mansion and went directly to Prince Chu's Mansion to tell Second Prince Zhao Zhen the news that Prince Qing's Mansion was planning to buy that batch of colored glaze.

"Your Highness...that batch of colored glass is worth over 4000 million silver. It's a sure win if you take it."

If there is a 20% profit, capital will be eager to move; if there is a 50% profit, capital will take risks.

If there is a 100% profit, capital will dare to risk being hanged; if there is a 300% profit, capital will dare to trample on all human laws.

Zhao Zhen's biological mother, Concubine Zhang, was from a prominent family in Jiangnan and had strong financial resources. She could make 1000 million taels of silver from 3000 million taels of silver. Not only could she make money, she could also prevent Prince Qing from making money.

However, recent signs indicate that the Plum Blossom Guard may not be as loyal as imagined, and he does not trust them as much.

"Tell me your plan first."

A barely perceptible gloom flashed in the eyes of the man in black robe as he told him his plan. Zhao Zhen thought about it and felt that there seemed to be no reason to refuse?

"Go to the mansion to get the money, and I'll have someone cooperate with you."

Zhao Zhen sent guards from the palace to accompany him to ensure the safety of the money, which made Hei Pao even more determined.

The situation in the northwest is temporarily stable, and the follow-up plan is about to begin. Zhao Zhen, this idiot, will suffer a lot if he doesn't die. It's time to make a fortune and leave.

Zhou Jin didn't care which of the two princes would get Liuli. He was more concerned about the safety of the Qin Palace and the Xiao Palace.

Whoever gets the Liuli will suffer heavy losses, and might even become desperate. The security work of the Qin Palace and the Xiao Palace must be taken seriously.

The guards that the emperor gave to the Qin Palace were a garrison with a strength of 5600 people. Such a number was not enough in the cold weapon battlefield.

It is more than enough to protect the house.

The Xishan military camp was handed over to the Ministry of War, and all personnel were withdrawn. Xiao Yunxi was temporarily free, so she took this opportunity to reorganize the Qin Wang Guard.

The Qin Wang Guards were fully staffed with 5600 men, including one guard battalion, one scout squad, one engineer battalion, one medical and logistics squad, and three mixed infantry and cavalry regiments.

Guard Battalion 550 people,

The members consist of 500 new soldiers and 50 secret guards, all equipped with the continuous sleeve crossbow designed by Xiao Yunxi, and the secret guards are equipped with grenades.

Divided into 5 teams, each team has 110 people,

They are responsible for Dabao's safety, which requires absolute loyalty and super high experience. The battalion commander is Zhou Er, the deputy battalion commander is Hu Zi,

Scout team of 30 people

The team consists of 30 new soldiers and is temporarily led by Tuesday.

Engineer Battalion 550 people,

The members consisted of 50 new soldiers and 500 newly recruited workers who participated in the construction of Xishan military camp.

There was no concept of engineers in the wars of the cold weapon era, so Xiao Yunxi had to train them in advance to prepare for future changes in the war situation.

Therefore, when selecting workers for the Xishan military camp, she specifically instructed Shen Wansan to choose young people who were smart, had experience in carpentry and bricklaying, and were willing to join the army.

Battalion Commander: Xue Yanze, the backbones are all the new troops recruited from the northwest

There are three mixed infantry and cavalry regiments, led by Zhu Ming. Each regiment will be sent 250 new army members, and the rest will be recruited from scratch.

The medical team and logistical support, 200 people, are temporarily under the charge of Zhu Ming.

At present, only the infantry and cavalry mixed regiment is not fully staffed. All other battalion-level units have been completed, except for the guard battalion, scout team and medical team who followed Dabao back to Beijing.

All other units will receive training in Xiaojiazhuang.

in addition,

Niuniu and Xiaobao are princesses and princes, and can have 50 guards respectively. Xiao Mansion recruits 50 servants, all of whom are selected from the new army and secret guards.

For the time being, all the responsibilities will be handled by Wednesday.

The military force has taken shape, but the weapons and armor are not yet in place.

Most of the weapons in the space are marked and cannot be used directly. Asking the emperor for them is not a good idea at this time, as blast furnace steelmaking is imminent.

Behind the mountain of Xiaojiazhuang,

After a month of improvement and debugging, Wu Chunfeng turned the design provided by Xiao Yunxi into reality, but he didn't know whether he could really produce steel.

"let's start!"

Xiao Yunxi looked expectant.

Blast furnace steelmaking can produce real steel, which is much harder than today's iron weapons. Whether it can be successful will determine the combat effectiveness of Qin Wangwei.

It is also related to the construction of refugee resettlement sites. Without the production capacity of blast furnace steelmaking, it is impossible to meet the huge demand for steel bars.

and also,

The iron that everyone refines has too many impurities.

If the hardness of the machine tool does not meet the requirements, it cannot be upgraded. If the material of the gun barrel does not meet the standards, it is impossible to produce more powerful weapons.

Bicycle bearings and wheels also require good steel as materials. Even cement is related to steelmaking.

The cement currently being fired is the most common Portland cement. Its raw materials are a mixture of limestone and clay, and it is a general-purpose cement.

Mixing slag produced by blast furnace steelmaking can produce blast furnace slag cement, which improves the durability, impermeability and crack resistance of concrete.

We can build taller and stronger houses, bridges with larger spans, and roads that are harder and more durable.

Wu Chunfeng climbed up the ladder to the top platform and put the iron ore, coke and limestone into the blast furnace through the charging port on the top of the furnace shell.

"ignition."

The outer shell of the blast furnace is made of iron plates and the interior is lined with refractory bricks. Even so, you can still feel the heat coming towards you.

Wu Chunfeng was very studious and did not hesitate to ask questions. He asked Xiao Yunxi why coke and limestone were used in iron smelting.

Xiao Yunxi looked at Daya,

This time, Liangang Dabao and Zhou Jin were not there, and Xiaobao and Niuniu were too young to be interested in these things, so she brought Daya over.

Daya has rich life experience, is thoughtful and observant, and is a bit like Wu Chunfeng. With theoretical knowledge as support, she can learn more efficiently.

Wu Chunfeng is very strong in practical operation, and Daya can connect theory with practice.

There were beads of sweat on Daya's nose. She didn't know if it was because of the heat or nervousness. She knew that Xiao Yunxi was testing her.

"The teacher said that steelmaking requires high temperatures, and coke can provide the necessary heat..."

Xiao Yunxi nodded and gave her an encouraging look, asking her to speak boldly. Daya unconsciously straightened her back:

"The main component of coke is carbon, and iron ore contains a large amount of iron oxide. In the high-temperature environment of the blast furnace, coke will undergo a reduction reaction with the iron ore to produce iron..."

"What about limestone?"

Daya frowned and thought for a long time. She didn't expect that the function of limestone was actually normal.

Limestone plays an auxiliary role in the steelmaking process, controlling the pH of the slag, absorbing impurities in the slag, further reducing the impurity content in the molten iron, and increasing the yield of steel.

They did not leave for a full four hours until the slag was discharged from the slag outlet and the molten iron flowed out from the iron outlet.

Become!
