Chapter Ninety-Nine I went to the capital to be really rich In fact, it was not only Du Liang who was in awe of Quan Xu.Including Du Liang, almost all the villagers in Quan's compound have a deep awe of Quan Xu.Not only because Quan Xu is their owner, providing them with food and clothing, but more importantly, in the eyes of the people in the late Ming Dynasty, Quan Xu's ability can be called a god.Quan Xu didn't notice the details of Du Liang, he was thinking about efficiency.Just as Quan Xu was thinking, a fine and dense cold sweat appeared on Du Liang's forehead.He was very apprehensive and very uneasy.Jeon Wook thinks that he needs too many bricks.Just one city wall needs more than 30 million bricks, a city has at least four city walls, in fact, the four city walls are not a complete defense system, but also need to have a female wall (referring to the short concave and convex wall on the city wall), a city wall (the wall that surrounds the moon city, also called a battlement), a moat (also called a moat, surrounding the water body outside the city. ）, Moon City (also called Urn City, a small city outside the city gate to shield the city gate, the gate of the Moon City is called the city wall. ）City Gate, City Gate (Watchtowers on both sides of the city gate. ）Castle tower (a tower built on top of a city gate or wall.) ）, Castle (near the city and outside the city gates) Suspension bridge (a wooden cable-stayed bridge erected on the moat for easy travel. ）Enemy platform (that is, the tower on the city wall used to defend against the enemy, also known as pier platform, wall platform, horse face. ）Wait a minute.So roughly calculated, the bricks needed for the city of Quanxu are at least hundreds of millions, and the average output is only 2,600 pieces a day, which will burn until the year of the monkey?
Quan Xu looked at Du Liang: "Slow, slow, it's too slow!"
”When Du Liang heard this, he hurriedly breathed a sigh of relief, and then explained: "Master, this is a new kiln, it is a little damp, and the craftsmen are not very familiar with it......
It will be fast later!
”"What is the maximum number of bricks that can be burned in a furnace, and how much time does it take at the minimum?""
This ......"
Du Liang thought for a while and said: "Back to the master, we are building a small kiln now, if we build a large kiln, a kiln can burn 150,000 or 60,000 bricks, but it will take longer to burn that way, almost twenty-five days." ”In this way, the efficiency is indeed a lot higher than that of small caves, but the problem is that it is still too slow, with an average of six or seven thousand bricks per day, which is only equivalent to more than 50 square meters of two or four walls.Quan Xu shook his head: "It's still too slow!"
”"That's how the bricks burn!"
Du Liang was a little frustrated: "If the number of days of burning is not enough, the bricks will not be strong." ”Several craftsmen behind Du Liang were depressed, and the green bricks were burned like this.In fact, after the research of later experts, the green bricks are fired from clay, and the clay is the product of the long-term weathering of some aluminosilicate minerals, which has a strong viscosity and gets its name.The clay is mixed with water to make bricks, which are calcined in a brick kiln (900°C-1100°C for 8-15 hours) to make bricks.Clay contains iron, and when it is completely oxidized during firing, it produces ferric oxide, which is the most commonly used red brick.However, if water is added to cool during the firing process, the iron in the clay is not completely oxidized to form low-valent iron (FeO), which is cyan, that is, green bricks.The hardness of green bricks and red bricks is about the same, but the cooling method is different after firing, while the red bricks are naturally cooled and simpler, so there are many red bricks produced, and the green bricks are water cooled (in fact, it is a kind of anoxic cooling), which is more troublesome to operate, so the production is relatively small.Although the strength and hardness are similar, the performance of green bricks in anti-oxidation, hydration, atmospheric erosion and other aspects is significantly better than that of red bricks.Quan Xu checked the information in this regard, and the brick kilns in ancient China had kiln roofs, and on this basis, the kiln sealing technology was developed - at the end of firing, the workers completely closed the smoke exhaust port and the furnace air inlet, and the kiln immediately entered the oxygen-deficient environment, and the blue-gray color of the green bricks was fixed.Quan Xu once visited the Suzhou Garden, and he also liked the gray and white architectural style of the Suzhou Garden, and he also thought about building a city with blue bricks to create a northern version of the Suzhou Garden.However, the problem is that he needs too many bricks, even if it is a large kiln, one kiln can fire 130,000 to 150,000 bricks, and this production takes up to 25 days.A large kiln can burn 1.8 million bricks a year, and for the bricks needed for the castle of Quanxu, at least 100 such large kilns need to be built, employing 30,000 or 40,000 craftsmen.Even if they don't have to pay for their work, 30,000 or 40,000 people need to lose 6,000 or 7,000 tons of grain a year, plus other living materials, and the cost is not low.However, Quan Xu never considered buying red bricks from later generations, just kidding, the red bricks of later generations have been sold for more than six cents, if it is hundreds of millions, then the input cost will need hundreds of millions.Jeon Wook originally wanted to do things, but now he finds that everything is too difficult.Although there was an obvious price difference between the late Ming Dynasty and later generations, and a large amount of price difference could be earned by reselling silver and gold, the problem was that there was very little gold in the Ming Dynasty, and it was rarely circulated.Thinking of this, Quan Xu looked at Du Liang and said, "What is the biggest problem you have in burning bricks?"
”"Burn a lot of firewood!""
It's too hard and too slow to make bricks!""
The brick kiln cools slowly!""
And ......," said several craftsmen."
There is a lot of firewood, why don't you use coal, it's charcoal?"
Quan Xu is a little strange, Handan in later generations is a famous coal resource city in China, with 4 billion tons of coal with proven coal reserves, and nearly 500 million tons of iron ore.Du Liang shook his head: "There is no near us, and the nearest carboniferous mine is more than 100 miles ......"
Quan Xu then remembered that the important resources of Handan City are concentrated in the central and western regions, and Quan Xu's location is the southeast of the Daimyo's Mansion, which is connected to Kaizhou.Kaizhou is the Puyang of later generations, in the Ming Dynasty, Puyang's Qingfeng, Nanle, Puyang are all under the jurisdiction of the Daimyofu.However, compared with Handan, Puyang is more abundant in resources, and Puyang not only has Zhongyuan oil fields, but also as many as 80 billion tons of coal resources and more than 100 billion tons of salt mines.Quan Xu thought for a while and said, "You guys go back first, and continue to build a big brick kiln according to the standards of the big brick kiln!"
”Although the production efficiency of red bricks is much higher than that of green bricks, green bricks have low output and are difficult to manufacture, and red bricks have gradually become the mainstream in the market.If for economic and efficiency reasons, Quan Xu should choose to burn red bricks, but Quan Xu does not think so, he just wants to build a castle of blue bricks and gray tiles, maintain the style of the Ming Dynasty, and at most choose reinforced concrete for the foundation.After thinking about it, Quan Xu decided to purchase coal from Kaizhou to be used to burn bricks.Although the transportation capacity of later generations is strong, it is completely possible to transport coal by buying some coal kings.But the crux of the matter is that there is no good way out now, and as the weather warms up and freezes easily, it is still a question whether his Doomsday Fortress can escape.The impact of the Hummer is not too great.The biggest advantage of getting coal from Kaizhou is that it can be transported by water, and this Jiagou River is a tributary of the lower reaches of the Yellow River, which can flow directly into the Yellow River, which was originally the river that was washed out by the flood discharge from the Yellow River's breach.Quan Xu instructed: "Go and invite Steward Yuan over!"
”After a short time, Yuan Shiqing came to the main house.Quan Xu looked at Yuan Shiqing and said, "Do you know what the price of coal is?"
”"You know, for a penny per catty, the volume will be cheaper!"
Quan Xu calculated carefully, one pound is a penny, and one ton is two taels of silver, which is a little expensive."
In this way, you take a few people to Kaizhou, buy coal, and sand and gravel, and ask them how much they send coal and sand and gravel to us!"
Quan Xu is also a little anxious, in just three months, I don't know, the pine forest has been reduced by one-third, if the kiln is burned for a few more months, I am afraid that the pine forest will be cut down.After arranging for Yuan Shiqing to go to Kaizhou to buy coal, Quan Xu considered that he could use water transportation to transport it, and he needed a lot of coal anyway.Quan Xu prepared a set of stab-proof suits for Sanniang and Erniang, but Erniang disliked the stab-proof suits and was too ugly to wear them.However, she still accepted the kindness that Quan Xu gave her.On the sixteenth day of the first month, when the women's square was opened, Quan Xu did not come to participate, not because he did not want to break the rules he formulated, but he directly returned to the afterlife and asked Su Tong to purchase four semi-automatic brick machines.Quanxu also did not think of mass production, a semi-automatic brick making machine, which can be driven by a four-cylinder diesel engine with 120 horsepower.The structure of the whole production line is simple, the key is that the production capacity is quite powerful, a brick making machine can produce 8,000 to 12,000 bricks in an hour.If it works 24 hours a day without stopping, it can produce 280,000 bricks, and four units are 1,152,000 bricks.That's more than 34 million bricks a month, which is enough to meet the cost of building a castle.When Quan Xu came back, Chen Ying also came back from Beijing, and he excitedly reported to Quan Xu."
Master Quan, this harvest ......"
Without waiting for Chen Ying to finish speaking, Quan Xu smiled: "It should be good!"
”"It's not good, it's very good!"
Chen Ying smiled so much that his eyes were almost out of sight: "Guess how much it cost this time?"
”The crystal products of Jiuyuanjiu Supermarket are not of high quality in terms of quality, otherwise they would not be sold in Jiuyuanjiu Supermarket."
Do you have a hundred thousand taels of silver?"
Quan Xu guessed that according to Chen Ying's results from Nanjing, he sold more than 64,000 taels of silver in Nanjing."
More than that!""
One hundred and fifty thousand taels?""
It's 500,000 taels!"
Chen Ying put the bill in front of Quan Xu.Quan Xu took the account book and looked at it hurriedly, only to see that it was written on Jiadingbo: 4,200 taels of three-color crystal carriage, 5,100 taels of gold fortune tree, and 6,800 taels of Amethyst Family and Wanshixing.Jiadingbo is the father-in-law of Emperor Chongzhen, and Zhou Kui, the biological father of Empress Zhou, is famous for asking for money and not dying.In history, Liu Zongmin forced Zhou Kui to hand over the donation, first killing his wife and daughter-in-law to commit suicide, and then killing his son.Zhou Kui was still reluctant to come out with a tael of silver......
Quan Xu was dumbfounded: "I'll go, the people in the capital are really rich!"
”Chen Ying sold the crystal ornaments for more than three times the price of the Daimyo's mansion, but Jiading Bo alone bought more than 43,000 taels of silver crystal ornaments.
