Back to Ming Dynasty with Industrial Revolution System

Chapter 955 Minting machine, dragon coin (three more)
While the shipyard secretly set off a wave of manufacturing steamships, Chu Yun was busy preparing for the reform of the currency system.Instead of ship-shaped silver ingots are silver dollars.The production of qualified silver dollars is the prerequisite for currency system reform.If even qualified new metal currency cannot be produced, it will be impossible to recycle silver taels of different shapes and finenesses.

Chu Yun took Da Yuer and some other officials in charge of currency reform to a factory.

This factory is different from ordinary factories. The inspection is stricter and guarded by soldiers with muskets on their backs. Even if Chu Yun and the others enter, they need to register normally.

"It turned out to be the military leader and several adults from the household department! I will notify the factory manager immediately!" The person in charge of registration was surprised when he knew the identity of the visitor.

"The mint is the property of Bank of Kyushu, and the right to mint coins is owned by Bank of Kyushu, and Bank of Kyushu needs to obey the decision of the Ministry of Accounts on issuing and recycling currency, and carry out production activities according to the decision." Chu Yun asked Dayuer while waiting for the factory manager to come out. Introduce this new factory.

"After a while, a German engineer brought people out, elated: "Master, you have come, the silver dollar sample you ordered to be produced has been successfully minted.Please allow your subordinates to lead the way! "

The German engineer who served as the factory manager led Chu Yun and the others into the mint, because it involves the casting of silver coins, copper coins and even gold coins. There is a batch of gold and silver parked here, and the value of the "product" is extremely high, so the management is strict.

"This is the toggle press we produced. It is simpler than the screw press, and the vibration and noise are not as great as the screw press." A German engineer introduced a strange machine to Chu Yun and others.

Da Yuer saw a large flywheel and the machine body. The flywheel was connected to the body of the minting machine through toggles and connecting bars, and the steam-powered machine was used.The first time she saw a machine for minting silver coins, she was secretly amazed.

"We investigated the coinage method in the East, most of which use the pouring method, that is, the metal is heated and melted into a fluid, and poured into a mold to make coins. This method originated from China, and Japan, Korea, Annan and other countries all imitated China. This method. It is undoubtedly a relatively advanced and practical technology in the past. It is more efficient than Western hand-beating coins with heat, and can produce more coins. However, at the end of the Renaissance, the use of spiral presses and After rolling the roller bed, it would be more suitable to make coins at room temperature through the machine, so we gave up this high-temperature operation.”

"This elbow press is more advanced than the screw press and roller press. It can punch 90 times per minute and produce coins with serrated edges, smooth edges, and letter edges. Lord, look here, The toggle part is the most important part of the toggle press. The use of the best quality steel in the steel factory will make the toggle press very durable, even if it is used for decades. There is absolutely no problem. The steam power can make the This machine produced a steady stream of silver coins without complaint." The German engineer proudly introduced his work.

Chu Yun touched the elbow joints and connecting bars, and the precise mechanical texture came from him, which made him admire the rigor of German engineers. In the 19th century, Germany was able to rise to become an important country in the second industrial revolution under the siege of Britain, France and Austria. Crowds are not unrelated.

"Where are the samples of silver dollars?" Chu Yun wanted to see if the minting machine could produce the silver coins he wanted.

"My lord, this is the first batch of silver coins we produced as required. There are a total of 120 silver coins, which are divided into 4 specifications, 26.6 grams, 13.3 grams, 5.3 grams, and 2.6 grams. The silver content is 90.5%, and the rest are Copper. In actual production, there are some deviations in the weight and silver content of different silver coins, but the overall conforms to the Gaussian distribution, and the error is within an acceptable range." The German engineer continued to introduce, and also used statistical methods.

The apprentice next to him brought a paper box of silver coins, which was divided into four compartments, and there were four stacks of silver coins, big and small, which were ten yuan, five yuan, two yuan, and one yuan.

Chu Yun took out a silver dollar with the largest denomination weighing about 26 grams, and the unique texture of silver came from his fingertips.

This silver dollar is the ten-yuan silver dollar with the largest denomination. On the front is the denomination and minting time of the silver dollar, and on the back is a dragon pattern with teeth and claws.

Domineering silver dollar!Chu Yun saw that the dragon pattern on the back was not only iconic, but also had artistic value.After adopting standardized machines, the silver dollars produced are very regular, more refined than the Spanish silver dollars currently circulating in the international market.

The Spaniards mined silver mines in the Americas, obtained a large amount of silver, and cast it into Spanish silver dollars to circulate in various places. From the end of the Ming Dynasty to before the Opium War, because of China’s foreign trade, a large amount of Spanish silver dollars flowed in, and its quality was favored by the southeast coast. People love it.Later, after the Opium War, a large amount of Spanish silver dollars flowed out, which became rare instead.

Chu Yun's purpose is to produce a new batch of silver coins to replace the Spanish silver dollar in international trade.

"The silver content is almost the same as the Spanish silver dollar, and the manufacturing is more precise than the Spanish silver dollar. It will accompany our commodity circulation all over the world." Chu Yun has high hopes for this new silver dollar.

"According to the current manufacturing process, as long as the raw materials are sufficient, the first batch of silver dollars can be produced day and night." The German engineer said.

"One machine is not enough, the size of our country is too big, and there are so many silver taels among the people that it is unimaginable." Chu Yun said.

"Then we will produce another four minting machines? Five minting machines produced the first batch of silver dollars, and put them into the market to see how the people respond. If the response is better, we will manufacture new minting machines." Wu Wu hum said.

"No problem. If the quality of the first batch of silver coins can be guaranteed to be so good, ordinary people will be satisfied. After all, the Spanish silver coins have helped us verify the feasibility of this silver coin." Chu Yun said.

He didn't know that this batch of silver dollars with a dragon pattern printed on the back would be called "dragon coins" by international merchants, replacing the Spanish silver dollars as the standard currency used in international trade in the future.

"What do you think of this silver dollar?" Chu Yun handed the silver dollar to Da Yuer.

With a crisp sound, Da Yuer accidentally touched Chu Yun's finger when taking the silver coin, and the silver coin fell to the ground.

Rao Da Yuer, who was so calm, also changed color slightly after recovering. She didn't take what Chu Yun gave her.

Da Yuer hurriedly bent down to pick up the silver coins that fell on the ground, but the silver coins fell to the ground again in a panic. Employees are watching.This was her first gaffe.
