My Daming New Empire

There is still waiting for cement production, and the current cement production is in short supply, so the curing project of the river embankment is progressing slowly.

But Zhu Zhanji is not in a hurry, as long as he has promoted the development foundation of the entire industry, he actually doesn't need to worry about it later.

Because seeing the benefits, anyone has enough motivation.

All he needs to do is to lead the development direction, and then occasionally guide the progress of some new technologies.

The forging plant and casting plant are located downstream of the research center of the Ministry of Industry, and belong to the internal supervision industry.Here are eight large warehouses tens of meters long.Next to the river is the workshop, and then there is a large yard, which is full of refined coke transported from Huaibei.

There is only one steelmaking furnace here, which is still experimental, and the rest are all furnaces for refining gold and silver.

Countless loose silver will be smelted here to become five taels and 50 taels of silver ingots, and then supplied to the imperial court for circulation or rewards.

When gold coins and silver coins have not been successfully developed, these casting tasks cannot be stopped.

Because it is too close to the capital, there is no iron-making furnace here.The iron ore in Ma'anshan has not been discovered yet, and Zhu Zhanji has no intention of developing it.

The iron used here is all smelted into iron ingots in Daye.Then it goes down the Yangtze River and is directly transported here, and then undergoes secondary steelmaking, or tests other high-strength steels.

Manganese steel with a ratio of more than 13.00% was tested here, and then the craftsmen used wax erosion, files, and grinding tools to make Qian Fan bit by bit.

All the Qian Fans were made by many people at the beginning, but the last step of polishing was all polished by a 51-year-old veteran craftsman named Meng Shuangquan from the Ministry of Industry.

At present, four manganese steel coin fans have been made, each with two upper and lower sides, and four silver coins can be forged at the same time.

On the front of the silver coin is a clear profile of Zhu Di, with the Ming Empire on the top, the Yellow Emperor's calendar on the bottom, ears of wheat on the left, ears of rice on the right, and a circle of sawtooths around it.

The image on the reverse side is the sun on the upper left and the moon on the lower right, one convex and one concave, forming a Tai Chi pattern.There is also a dragon around the circle, and between the dragon head and the dragon tail, there is a capital one or two.

In fact, forging is the same as casting, and both need vent holes. According to the design, the vent hole is at the position of the faucet on the back, which happens to be a longan exposed.

After Zhu Zhanji made the first yuan, he first forged forty silver coins by manpower, using the "pure silver" in circulation.

The forged silver coins are actually less than one tael, but the difference is very small, and the weight difference is because it is now "pure silver".

When large-scale forging is performed in the future, only [-]% of the composition of silver will be retained, and the remaining [-]% will be an alloy of copper, nickel and lead.

Of course, this is because of the cost, but more because silver is relatively soft and easy to wear. After adding alloys, it can enhance the hardness and toughness, and the service life is longer, and it can also prevent rust.

After the sample money was produced, Zhu Zhanji gave it to Zhu Di for the final version.

Not to mention how happy Zhu Di was when he saw his profile face printed on the silver dollar.Because of the little anger caused by him going to the sky privately, it dissipated, and Zhu Zhanji was greatly praised.

Zhu Di is quite satisfied with the overall design of the silver coin, especially the idea of ​​using serrations to prevent wear and tear. Zhu Di praised Zhu Zhanji very much.

Only for the Huangdi calendar, he felt a little uncomfortable, because he felt that his own year should be printed.

However, Zhu Zhanji still persuaded him with orthodox theory. In fact, in his heart, he wanted to promote the commemoration of the Yellow Emperor Calendar and break the Western commemoration of Jesus.

In the east, because of the chaotic calendar, the whole world used Jesus to count the year. This is actually the biggest suppression in the east.

The current Zhu Zhanji certainly does not want this situation to continue, so he decided to fully promote the Yellow Emperor Calendar from now on.And as long as this date is printed on the coins, all Asian countries will recognize this date in the future.

Although Zhu Di was very satisfied with the design of the silver coins, he volunteered to get the right to design the gold coins and planned to design a set of gold coins himself.

However, due to the design problem of the hydraulic forging press, it has not been mass-produced until now.

Among them, the biggest remaining problem is the procedure of lifting the forging hammer, which is actually the problem of whether the hydraulic force can be accumulated.

Unlike a steam engine, hydraulic power can accumulate power, which leads to a stable output of hydraulic power, but there is a limit to the maximum power.

The power can be solved by the gear output ratio, but how to make the forging hammer work continuously, the key is still a transmission problem.

Before coming, Zhu Zhanji thought of a solution, which is actually very simple, that is, a crankshaft transmission method.

Whether it is a four-cylinder engine or a six-cylinder engine in later generations, it is actually a crankshaft.But this crankshaft can drive four and six cylinders.

If the piston is regarded as a forging hammer, two forging hammers go up and two go down, so that the rotation alternately goes up and down, which can not only solve the problem of power stability, but also solve the problem of transmission.

I just don't know if today's water power can drive such a large force.

Because under the tests of the craftsmen, if the working range of the forging hammer is one meter high, and if you want to forge silver coins with the most suitable force, the weight of the forging hammer needs to be [-] kilograms.

After Zhu Zhanji explained his sketches and solutions to a group of people from the Ministry of Industry in detail, they felt that it was feasible just by seeing the drawings.

In many cases, an invention is just a layer of window paper. After it is broken, everything becomes clear.

Now, the key is to cast the model of the crankshaft in mud and then sand it.Even if a group of people with the strongest technology in the entire Ming Dynasty gathered here, this process would probably take at least half a month.

After arranging these tasks, Zhu Zhanji can ignore them again, and he is going to take Lan Yan to Jiangxin Island to play around.

It's not easy to have the opportunity to meet the beautiful woman by chance. This is also their first date. It would be a pity to waste this opportunity.

Lan Yan, a silly girl, has finally come to her senses. It may be that what happened today made her see her own destiny clearly.So after coming to the industrial zone, he refused to show his face again.

However, in order not to bear Zhu Zhanji's disappointment, he agreed to take a boat trip to Jiangxin Island with him.

And in the palace opposite the city, Zhu Di also knew what Zhu Zhanji did today, and couldn't help laughing and scolding: "This bastard, he doesn't understand etiquette at all. Even his unmarried concubine, Liangdi, shouldn't be in the street." Go up and hug and hug, how decent it is."

-------------Chapter Dividing Line---------------

Zhu Zhanji is a person who doesn't understand feelings, and his wife in the first life divorced him.Of the three wives in the second life, the first one chased after him, the latter two were coerced at the beginning, and later, due to a combination of mishaps and interests, they became his wives

Then, in the first life, so many women were all related to money, and in the second life, they were a little more elegant, mainly because of the relationship of interests.

Such a person, if not because of his wealth, would never be able to win the hearts of women.

However, such a person, after coming to this era, feels like he has become a lover because of his noble status and his equal regard for women.

No matter whether it's a casual remark about whether it's hot or not, or handing over a handkerchief to wipe sweat, or even reaching out to hold Lan Yan when getting on and off the boat, it's amazing.

Not to mention Lan Yan, even the Indus who was still a bean sprout looked at Zhu Zhanji with eyes full of admiration and reverie.

I think it's really rare for Zhu Zhanji to be such a considerate man with such a high status, and women like him so much.

The original worry turned into surprise, and she secretly asked Lan Yan: "Miss, I want to accompany you into the palace, after that, will I also serve His Highness?"

Embarrassed, Lan Yan pinched her little butt. "What nonsense are you talking about? Have you forgotten the explanation of the maid and aunt? Dare to seduce the grandson and violate the palace rules. It's a punishment that makes you want to die."

"But grandson is really nice! So tall, so strong, so considerate, what a good match!"

Zhu Zhanji has practiced Qi for a long time, and his ears and eyes are sharp, so he can hear their words clearly.She turned her head and grinned: "Little girl, you're only old this year, so you already know what a good match is!"

Seeing that Zhu Zhanji heard their whispers, Lan Yan and Wu Tong couldn't help but feel ashamed. Lan Yan covered her face, not daring to let Zhu Zhanji see her blushing face, but couldn't help but peek at Zhu Zhanji from between her fingers .

And that Indus who looked like a young girl was naturally ignored by Zhu Zhanji.

The desolate Jiangxin Island is actually not much fun, the sun is scorching, and most of the farmers by the river are working naked, so the two women can't get close.
