Chen Deli actually has nothing to talk about with the foreigners on the beach, because the value of Shanghai to the foreigners no longer exists.

Unless they can send a fleet to open up sea lines of communication.

Of course they have the ability, it just takes time.

Today seems to be Dong Liang's interview day. Guan Yan has arranged two interviews for Dong Liang.

But before the two interviews, Dong Liang first went to Mawei Shipyard.

After the last flood, the construction speed of Mawei Shipyard not only did not slow down, but also accelerated.

On a hillside far away from the shore, the foundation of a steam engine workshop is being laid. The factory building has not yet been completed, but the steam engine laboratory has been built. The laboratory equipment has been transported from Anping City.

Along with the equipment came Mark Stevens, whose accomplishments in steam engine manufacturing even impressed Dong Liang.

Dong Liang went directly into the laboratory to inspect Stevens' work.

This white man has an attitude of taking what he has come and taking care of it, and devotes himself wholeheartedly to his work. Of course, his main motive is to make money.

When Dong Liang saw him, the man was assembling a strange-looking steam engine model.

The performance of a new steam engine can be verified through a reduced model.

"Mr. Stevens, how are you? Can the idea I mentioned last time be realized?" Dong Liang walked to Stevens' side without interrupting the work in his hands.

"Mr. Yuan Xian, the design you proposed is theoretically feasible. The principle of the steam engine is to convert the heat energy generated by coal combustion into kinetic energy. So as long as the utilization efficiency of heat energy is improved, the working efficiency of the steam engine can be improved. Its output

The motivation will be stronger.”

"Everyone knows this principle, but what is missing is a good idea to realize it. If this two-cylinder horizontal steam engine can be realized, we can also make a three-cylinder triple-expansion steam engine in the future. Such a steam engine can be installed on the ship

The power on board is powerful, much more powerful than the mainstream steam engines today."

"Of course, if you want to make a more powerful steam engine, the requirements for materials are also higher. With all due respect, with the steel you are making now, the steam engine you can make, even if the design is improved, can only reach 5,000

Horsepower." Stevens is indeed a technical man, and he is simple and direct when talking to Dong Liang.

"Enough, 5,000 horsepower is enough for the time being." Dong Liang remembered that the displacement of the Warrior was more than 10,000 tons, and the output of the steam engine seemed to be only more than 6,000 horsepower. That power could already make the Warrior reach an astonishing speed of 14

knots, including its sails, of course.

If he installs a 5,000-horsepower steam engine on an armored cruiser of more than 3,000 tons, wouldn't it be possible to reach a speed of more than 20 knots? This is just Dong Liang's layman's idea. In fact, this is not the calculation, because it will affect the ship.

There are many other factors involved in speed.

Dong Liang felt that this speed could basically defeat all warships at this time.

It doesn't matter how advanced the weapon is. Even if Dong Liang is a time traveler, he can't lead his men to build a 10,000-ton weapon from the future.

He just needs to make his weapons stronger than his enemy's.

"Mr. Stevens, just ask if you need anything. Even if the steel does not meet the standards, I can have people develop better quality steel. Our Chinese heavy industry is integrated, and you can call on any resources.

"Dong Liang said.

Such a guarantee is the highest preferential treatment for a mechanic.

However, Stevens's brain circuit is different from normal people: "Mr. Führer, it's actually nothing. As long as you can give me a salary increase, I think I will be able to complete the trial production of the new steam engine ahead of schedule, at least it will be better than the hull in the shipyard."

The construction speed must be fast. I like real money, and those shopping coupons are of no use to me, I don’t need to buy anything at all.”

Dong Liang secretly laughed, this person is obsessed with money, but since the other person likes money, so better.

"Haha, okay, no problem. As long as you can make this horizontal double-cylinder steam engine, I can give you a reward of one thousand taels of gold, which is a lot of gold."

Dong Liang thought, just give it to you, since you can’t take it away anyway. As long as the gold is still on the land of the Chinese, it will still belong to the Chinese.

If he can tell the other party about the idea of ​​this new steam engine, then it is absolutely impossible for him to let the other party leave.

Just like how Americans used Chinese workers, Dong Liang would completely drain these American engineers. Who said they were prisoners?

There are more than a dozen workshops with clearly divided labor in the shipyard, and the factories here are not only prepared for shipbuilding.

For example, the gun factory not only produces naval guns, but also produces coastal defense guns and army field guns.

Dong Liang went over to take a look at each workshop. Many of these workshops were built with shelves, no factory buildings, no equipment, but all scientific research personnel were available.

In this shipyard, everything from naval guns to warships will adopt new designs. Therefore, the research and development team is very important.

In the shipbuilding laboratory, Dong Liang met Manjiro and other engineers.

They now have several models of warships in their hands. The iron-sided wooden hull ship still needs to be built as a fast light frigate.

This kind of warship of about 1,500 tons will be the first batch of warships built by Mawei Shipyard. This time, five ships will be started at the same time.

Another type that is ready to be built in large quantities is the "mosquito ship" with a tonnage of about 500 tons.

This is an offshore defense gunboat that adopts the design concept of the Rendall gunboat, with the small boat carrying the big gun.

It is actually a mobile maritime fort that cooperates with the forts on the coastal defense fortress to defend against enemy fleet attacks.

Both types of warships can be built by the Chinese with their current technology.

The drawings that Manjiro is studying in his hands are of a brand-new type of battleship - an ironclad ship.

"Führer, this new type of armored ship will surpass all current warships in terms of performance. It is the future of our Chinese navy." When he saw Dong Liang, Wancilang had a look of admiration on his face.

The warship designs he is studying all come from Dong Liang.

Including the previous iron-walled wooden-hulled warship that was about to be completed.

In his eyes, the Führer was the most powerful shipbuilder in the world.

"Manjiro, we must build this kind of battleship as quickly as possible, and at the same time we must do experimental verification, and absolutely no mistakes are allowed. Especially in terms of craftsmanship, this kind of battleship is a new challenge for designers, and it is also a new challenge for workers.

It’s a challenge.”

The key process of ironclad ships is the riveting process. Early ironclad ships usually used riveting instead of welding.

Dong Liang also does not have the ability to directly weld and modularize the design.

The riveting process places very high demands on riveters.

If the Chinese want to work on the ironclad ship project, they must cultivate a skilled riveter.

With this group of workers, the Chinese will lead step by step in the construction of ironclad ships in the future.

Dong Liang went to the steel plant construction site in Minhou County again.

Whether it is casting a steam engine or building a battleship, casting artillery is inseparable from good steel.

In this era, the British were unique in their steel-making technology, and the steel they produced was famous for its high strength and strong plasticity.

It is precisely with this that the Armstrong Artillery Factory has become the largest artillery production factory in the world.

However, Krupp, who became famous in later generations, was still not well-known at this time.

Dong Liang had previously imported a batch of British steel through the Ryukyu Commodity Exchange.

It is indeed stronger than the steel he made using local methods at the beginning.

However, Dong Liang has restored the open-hearth steelmaking technology, and the Chinese have the conditions for large-scale steelmaking. Coupled with the discovery of the high-quality iron ore Minhou Iron Mine, it can be predicted that the Chinese will have a large amount of high-quality iron ore in the near future.

Steel.

Next, he would also perfect the casting process of the breech-loading cannon.

The Chinese are preparing to launch a technological revolution in Fujian to create the necessary scientific and technological conditions for Dong Liang to march across the country.

After completing his inspection of the factory, Dong Liang returned to the capital and began to receive guests.

The first person I saw was Rong Hong.

Dong Liang was very interested in this foreign student.

The Chinese now also send some overseas students under the name of Ryukyu Kingdom.

But these people have just left.

And Rong Hong has already completed his studies overseas.

It's just that Rong Hong studied humanities, and Dong Liang is now even more lacking in technical talents.
Chapter completed!
