Seeing the two people looking at each other, Su You added: "That's right, Handan's coal and iron industry will soon undergo major changes, so I asked you two to come here to learn about the situation beyond the control of government files."

"You two must tell the truth, otherwise when the newly invested production capacity is increased, it will have a huge impact on your industry. I want to try my best to avoid such a situation."

Dong Fei hurriedly beat the drum: "Old Li, Old Chen, all the officials in the world, if the Ming Dynasty can't believe it, then no one can trust it. No matter good or bad, just say it, if the Ming Gong listens, it will only benefit you and not harm you."

.”

Su Youwen said: "Based on what the government currently knows, the Handan Railway Supervision's production capacity is only a thousand tons per year. This ton is two thousand kilograms, which is two million kilograms. If you calculate it at 20%, it will be just one thousand kilograms."

Tens of millions of kilograms is not enough for a fleet of steam boats to haul it several times."

"Do you know the current production capacity of Xuzhou Iron and Steel Industry? With the support of Huainan Coal, the daily output is 50 tons. The output of Handan in one year is only ten days in Xuzhou!"

"Handan has more advantages than Xuzhou. Coal and iron are all in one place. If the imperial court wants to open up Handan Iron and Steel, it must rely on local talents. You two, this is an opportunity."

What they said made the two old men's hearts beat wildly. Back then, Handan had an annual output of 10 million kilograms of iron, and it was the only large-scale railway superintendent in Hebei. Later, when Hebei was in decline, this business declined.

Now that the imperial court is determined to revitalize Hebei, the two old men want to restore iron smelting to the level where their ancestors made tens of millions of kilograms a year, even if they can't use up the money to honor their ancestors. Now Ambassador Su told them that their ancestors used to be a big business that accumulated a family fortune of one hundred thousand kilograms.

Now it is just a fraction of the ten days in Xuzhou!

How many ten days are there in a year? Thirty-six, that’s an industry of 3.6 million yuan?

I heard that envoys never failed merchants. Chen Wuchang blinked and said clearly, "I am willing to help Ming Gong in his great cause."

Coal and iron are not divided into separate families, so Li Rusheng had no choice but to hand it over: "Only the bright male horse will follow his lead."

Su You said: "That's not what I mean. The final plan must satisfy all parties. Let's talk about the industry first."

Li Rusheng said: "Let me tell you first, Handan has produced iron since ancient times. "Guoyu·Qiyu" records that US dollars are used to cast swords and halberds, and they are tested on dogs and horses; bad gold is used to cast hoes and pounds, and they are tested on all kinds of loam. That's it.

The difference between copper and iron.”

"In Zuozhuan, in the 29th year of Zhao Gong, Fan Xuanzi made a punishment tripod made of iron."

"Handan has been prosperous in commerce since ancient times, and Lu Buwei became a rich man."

"Handan, Wancheng, Linzi, and Xiadu during the Warring States Period were all major iron and steel smelting cities in the north. Guo Zong, Zhuo and their ilk were engaged in iron smelting and were richer than the princes."

"His hometown is in today's Wu'an. This place name is also related to weapons manufacturing."

"The Han Dynasty Book Zhang Tang Chuan says that the state of Zhao was engaged in smelting and casting, and the king sued the iron officials."

"The Geography of the Sui Dynasty states that Cishan produces iron, which is magnetic and can lead a needle to prevent it from falling."

“From the Tang Dynasty to the early years of our dynasty, Handan was also known as the ‘Iron and Metallurgical Capital’.”

"Unfortunately, Hebei has been in decline since the Chanyuan Alliance. Although there is an iron industry, its output is low, and the coal industry inherited from my ancestors has also been greatly affected."

"So Handan is really a good place. According to our ancestors, Fuyang, Zhaode and Cizhou are all rich in coal and iron. Among them, there are outcrop mines near the river and in Shexian County."

"In addition, there is copper in Shexian County, lime, gypsum, and clay in Zhaode. There are also several large porcelain kilns in Cizhou, which use piebald stone as glaze. The porcelain produced is strong and durable, with clear black and white. The craftsmen

He is especially good at making large utensils. Speaking of which, although the porcelain in Sichuan is extremely exquisite, in terms of size, it is still the best in our northern region."

When Old Man Li talked about this, he kept talking like a treasure. When he finally couldn't hold it back, Old Chen on the side turned pale with fright and kept pulling on Old Li's sleeves.

Only then did Old Li realize that fine porcelain in the world was born in Meishan, and the wife of the nephew of the Prime Minister was a big boss in the porcelain industry. Oops, this was a disgrace to the Prime Minister!

Su You didn't take it seriously: "Meishan porcelain is exquisite. Pour water into a bowl and you can see the water line from outside the bowl through sunlight. But if you want to make vinegar-based sauerkraut, you have to be from the north."

, how big a vat can the Cizhou kiln make?"

There have been no records or cultural relics unearthed of large vats from the Song Dynasty in later generations, so today's vats are mostly stone vats, wood vats, and the more expensive ones are copper vats.

Therefore, the story of "Sima Guang smashed the vat" itself is worthy of discussion. A vat that can submerge a child of several years old is not small at all.

Of course, this problem has been solved by Liu Shidao, a famous purple clay pot maker from Liangzhe Road. This boy invented the grouting method to make porcelain bodies, which was enough to produce large porcelain jars like those of later generations.

It's even simpler here in Suyou. Iron wire is used as tire reinforcement, wet sand is used as the inner tank, and the tank is directly cast with cement. You can get whatever tank you want.

After the carcass is ready, the sand is washed out, the trachholes are filled with cement, small decorations such as cement-cast plates are affixed, the carcass is brushed with pure cement slurry and polished smooth, and then painted with gold paint.

There was no need for it in the inner palace. A circle was placed around the outer hall, filled with water and goldfish. It was both a decoration and a fire-fighting facility. At that time, it shocked the Liao envoys who came to congratulate Zhengdan.

Today's steel-making blast furnaces in the Song Dynasty require many things. Su You asked: "What materials do your furnaces use?"

Li Rusheng said: "You have to ask Chen Xingshou about this."

Chen Wuchang said: "Both the envoy and the judge are famous iron smelting experts in the Song Dynasty. This method is not hidden in my family."

"Hebei Iron and Steel Furnace Bricks use three types of soil - brine clay, porcelain clay, and alumina. The three soils are mixed in proportion and pressed into bricks to build the kiln. They can withstand high temperatures and will not collapse."

Su You couldn't help but be a little surprised: "Handan has all three types of soil?"

Chen Wuchang said: "Yes, in addition there are fire clay, purple clay and pottery clay from the coal kiln."

"The porcelain of Cizhou kiln is made of large green clay, but the porcelain clay is used less. The fired body is painted with white porcelain clay as a base, and then painted with piebald stone slurry. This saves money!"

Su You thought of several things. The glaze color of Cizhou kiln was rich. If he combined his techniques with Meishan craftsmanship, he would use porcelain clay to make a white body, then apply a thick glaze, and then use the glaze removal method of Cizhou kiln to create a red-red color.

The red and white porcelain with the effect of lacquerware, as a gift for Zhao Xu's wedding, would be called a high-ranking one who is unparalleled in the world.

Also, alumina is bauxite. The major scientific and engineering achievement of the Capital University this year is that after the little Celestial Master invented the electroslag smelting crucible, he became obsessed with the electro-alchemy process and believed that it was not close to the ancient immortal method.

Inspired by the electrolytic salt solution, Little Tianshi built a high-temperature electrolytic tank to smelt various molten salts, and unexpectedly prepared two new types of light metals.

One is the brine he has been studying, which extracts metallic magnesium from purified magnesium chloride.

There is also a process for preparing hydrofluoric acid. First, fluorite and sulfuric acid are mixed according to the ratio, and then added to the internal heating reactor to allow the fluorite and sulfuric acid to react to generate hydrogen fluoride gas, which is then absorbed with water to obtain hydrofluoric acid, which is produced by desiliconization.

into arginic acid.

Then add aluminum hydroxide slurry and soda ash solution into the reaction tank to control the remaining acid concentration. After the reaction is completed, the solution flows into the disc vacuum filter for filtration, and the filter cake is dried and dehydrated in the rotating drum to obtain artificial powder.

material.

Bauxite is smelted into fine powder, that is, aluminum oxide. The aluminum oxide powder is mixed and melted with this artificial powder, and electrolyzed to extract metallic aluminum.

Through processing in this way, the temperature does not need to be too high, and it can be completed at seven or eight hundred degrees.

These two metals are actually not very useful to the current Song Dynasty because the cost is too high.

Shi Fu did come up with an exquisite kerosene lighter, but not many people in the world could afford it.

Aluminum metal is lightweight. Shi Fu has designed several all-metal knives with aluminum as the handle patch, but there is nothing worthy of praise other than novelty.

However, Su You knew about the thermite reaction. Before the invention of the electric welding gun, iron could be turned into water through the thermite reaction for welding. This process was still used to weld rails in later generations.

"Messenger?" Li Wuchang didn't know that Su You was already distracted. After the report was finished, he didn't see any comments from the leader for a long time, and he couldn't help but feel uneasy again.

"Oh." Su You came back to his senses when he heard the call: "Hearing is believing, seeing is believing. I just need to take the time to go to your workshop to inspect it."
