Traveling through history leaving a name

Chapter 322 Development of Industry
As the number of machine tools in the Gunpowder Bureau increased, the speed at which other manual machines were manufactured became faster and faster.

After completing the order for one hundred hand-made machines, other bureaus of the Bingzhan Bureau placed orders for several hundred more machines.

It took the Gunpowder Bureau more than two months to make these machine orders.

Two months later, with the increase in the number of machine tools and the increasing proficiency of workers in operating machine tools, the speed of manufacturing manual machines has also become faster and faster, reaching a speed of thousands of machines per month.

There are more than 500 workers, and on average each worker can manufacture two hand-made machines per month.

This speed, in the eyes of others, is fast, but in Zhang Qingfeng's eyes, it is still too slow.

These manual machines are not very complicated machines, and an average of two per month for one person is really too little.

Fortunately, the manual machines of the Gunpowder Bureau were sold by Feng Mo. After seeing the efficiency of these manual machines, many yamen placed orders.

When selling it to other yamen, Zhang Qingfeng not only sold it at the original price, but also added two taels of silver to it. In this way, every time he sold a machine, he could earn more than three taels of silver.

However, at the current rate of 3000 machines a month, even if one machine earns three taels of silver, it can only earn [-] taels a month.

3000 taels, the wages of the workers alone cost more than 1000 taels, before Zhang Qingfeng could quietly put the money into his own pocket.

"Palmprint, the lower officials want to move the Gunpowder Bureau out of the inner city."

On this day, Zhang Qingfeng came to the Yamen of the Bingzheng Bureau and said to Feng Mo.

"Do you think the Gunpowder Bureau moved out of the inner city? Why?" Feng Mo asked in surprise.

"Because there is too much gunpowder stored in the gunpowder bureau, if there is a fire and an explosion occurs, countless people will be killed." Zhang Qingfeng explained. "If it is outside the city, even if there is an explosion, the loss will not be too great."

In the Ming Dynasty, in Shuntian Mansion, there were two yamen for the manufacture of firearms, one was the Arms Manufacturing Bureau of the Ministry of Industry, and the other was the Gunpowder Bureau of Wanggong Factory under the Military Warfare Bureau.

Among them, there is a gunpowder manufacturing factory under the Gunpowder Bureau, which has more than 30 people and can produce two tons of gunpowder every day.

Historically, in the year of Tianqi, that is, in 1626, there was a big explosion in the Gunpowder Bureau of Wanggong Factory.

At that time, thousands of tons of stored gunpowder exploded violently, causing more than 2 casualties. Even the under-month-old son of Emperor Tianqi was frightened to death by the loud noise.

"Palmprint, the Gunpowder Bureau has stored too much gunpowder, surrounded by densely populated residents, if a fire breaks out, the consequences will be disastrous. According to my calculations, at least 2 people will be killed or injured." Zhang Qingfeng said to Feng Mo.

The Gunpowder Bureau, built in the inner city, is definitely extremely risky. The apocalyptic explosion in history is the best proof.

Thousands of tons of gunpowder are equivalent to a tiny nuclear bomb.

"Our family still needs to report this matter. Whether it can be done or not will be decided by Long Live Lord." After hearing Zhang Qingfeng's words, Feng Mo finally said to Zhang Qingfeng.

The next day, Feng Mo reported to Emperor Wanli what Zhang Qingfeng had said.

However, Emperor Wanli's answer was only three words, which was not allowed.

For such a situation, Zhang Qingfeng was caught off guard.

"Qingfeng, don't take this matter to heart. Long Live does not allow the Gunpowder Bureau to move out of the city because it is a last resort."

Feng Mo comforted Zhang Qingfeng and said: "Gunpowder is the most important weapon of the country. If it is placed outside the city, it is easy to be attacked by the enemy. It is only safe if it is placed inside the city. Do you understand?"

Hearing Feng Mo's words, Zhang Qingfeng nodded. He could also understand the court's concerns. If the Gunpowder Bureau was located outside the city, it would indeed be easy for the enemy to attack and take advantage of it.

"Palmprint, even if the Gunpowder Bureau can't move out of the city, I hope that the gunpowder storage warehouse can be located in multiple places in the city, so that even if there is an explosion, there will be no serious accident." Zhang Qingfeng said to Feng Mo.

"Let me ask for your instructions again on this matter!" Feng Mo nodded and said.

Zhang Qingfeng's machine business has made him a lot of money, so he is also willing to help Zhang Qingfeng.

Soon, Feng Mo's memorial was sent to Emperor Wanli again.

This time, Emperor Wanli did not refuse, but adopted Zhang Qingfeng's opinion, and planned to set up a gunpowder storage warehouse in the southeast corner, southwest corner of the inner city, and the four corners of the outer city, east, west, north, and south.

In this way, even if there is an explosion in a gunpowder warehouse in the future, it will not be as strong as the explosion in Wang Gong Factory.

However, the Gunpowder Bureau's separate gunpowder storage warehouse has been greatly hindered.

Many people were frightened when they heard that the gunpowder storage warehouse was to be located nearby, and they all opposed it.

Some officials and dignitaries living nearby even asked Emperor Wanli to cancel the separate gunpowder storage warehouse.

In the end, the warehouse originally located in the southeast corner of the inner city was cancelled, and only the four warehouses in the outer city remained.

Even so, this incident was a victory for Zhang Qingfeng.

The Gunpowder Bureau couldn't move out, so Zhang Qingfeng's idea of ​​using water power fell through.

Therefore, Zhang Qingfeng was going to get the steam engine out.

In 1679, French physicist Denis Papen discovered that a boiling kettle could lift the lid, and then created the first steam engine.

After that, the steam engine was slowly improved until the appearance of the industrial revolution.

In fact, the steam engine at the beginning was not a complicated machine. It was born only because of a lack of an idea. As long as you know the principle, you can easily manufacture it. Of course, you don’t know if it is practical or not.

Also, don't ask the author how to solve the air leakage problem without a rubber steam engine.

Vulcanized rubber was only invented in 1839. The maximum working temperature is only 100 degrees, and it is more than [-] years later than the invention of the steam engine. Obviously, the steam engine does not rely on rubber to solve the sealing problem.

The steam engine solved the sealing problem. In the early days, fibers were used, and later metal piston rings were used. There was no rubber at all from the beginning to the end.

Moreover, the piston ring is not something that is too difficult to manufacture. As long as a certain processing technology is mastered, it is not difficult at all to solve the problem of air leakage.

In the following time, Zhang Qingfeng began to devote himself to making steam engines.

He had already studied the steam engine thoroughly during the Han Dynasty, so it is not difficult to manufacture it now.

The only thing that affected him was probably the machining accuracy of the machine tool, so Zhang Qingfeng had to polish many parts by hand.

In order to manufacture various parts of the steam engine, Zhang Qingfeng also built a small steelmaking furnace, which was specially used to refine a small amount of special steel.

In this way, it took almost three months for the various preparations in the early stage: building a steelmaking furnace, manufacturing various processing tools, collecting various metal materials, manufacturing various casting molds for parts, and so on. Create a steam engine from scratch.
