On the warm kang, the three of them were eating hot pot and drinking wine, and they were discussing the shipbuilding plan very warmly. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Zhang San was originally a sea merchant and was very interested in building sea ships, especially this novel and unique three-masted sea ship that was tall at first glance. And Cheng Qian has always had a unique yearning for the sea, and now he is interested in everything that is on the side of the sea, the boat, and the sea.

As for Li Chao, he doesn't want to care about the affairs of the court now, and he is a little tired and tired. I just want to stay on this Wudang Mountain for a little longer, anyway, if I have time, let's build a ship.

"But it's not that easy to build a ship. If we bring craftsmen here to build ships, we will be short of timber. ”

Wood for shipbuilding requires some special trees, and different parts of the ship need different wood. The most important part of the whole ship, the keel, has extremely high requirements for wood. Even if you can use keel splicing technology, the keel needs to be a very large tree, and it must be a very strong and corrosion-resistant oak and teak.

The other decks, masts, and other timbers are also very particular.

There is no shortage of wood in Shannan, and you can always find a suitable one when you go into the mountains to find it, even if it is a big tree that is needed for the keel. But the timber is found, it has to be cut down, transported back, and that's just the simplest.

What's more troublesome is that the trees are not transported back to the ship, and they have to be dried in the shade. A large tree, especially one as large as a keel, may require many years of shade drying.

"Actually, it won't take that long to dry in the shade, we can speed it up."

Zhang San put a piece of duck blood in his mouth, listened to Li Chao's words, and quickly shook his head.

"Ships have the highest requirements for wood, especially sea ships, if the wood is not dried in the shade, the ship will be deformed in the future, that is not good, it must be dried in the shade."

Li Chao smiled, of course he knew such common sense, but wood drying is not only shade drying. In the Age of Discovery, in order to speed up shipbuilding, there were special lumber mills, who were responsible for logging and processing. Processing involves not only cutting down trees and sawing them into various boards, but also drying.

The lumber mill will build a special drying cellar, and the cut trees will be directly sawn into slats of various sizes according to the needs of use, and then the wood of the same humidity and the same scale will be stacked in the drying cellar for drying.

In this way, the drying speed is greatly accelerated.

The principle of drying wood in the drying cellar is actually very simple, that is, the desorption process of wood is accelerated by water vapor in the drying cellar.

There are two types of water in wood, one is the water absorbed in the cell wall, and the other is natural water. The main purpose of drying is to remove the absorbed water, a process called desorption, and the effect of free water is not great.

When drying in the cellar, it is very important to stack the wood, and the cross-section of the wood at both ends should be coated with wax to prevent cracking.

Zhang San was amazed when he heard this.

I can't imagine that there is such a way to speed up the drying of wood, ordinary shipyards, are the easiest way, buy wood every year, and then first sawn the tree, sawn into boards as required, and then take wax or lacquer to seal the section, and then set up in the shed to dry naturally. Some are even simpler, and instead of cutting down the trees, they peel off the bark at the bottom and let the trees die naturally.

After the tree has dried up, it is cut down and transported back.

The simpler the method, the easier it is for the tree to crack.

Therefore, it is generally cut down wet wood, and then transported back to be sawn, and then stored in the shade to dry. This is because the more intact the tree, the more likely it is to crack.

But those methods are undoubtedly far inferior to Li Chao's use of cellars to dry, which is fast and time-saving.

"I didn't expect that even drying, Li Xiang has such an advanced method."

"Building a drying cellar is not simple, and the operation is also very complicated, different wood drying methods are different, and even different wood specifications are not the same, in addition to summer and winter, it is also different. You also need to have a lot of experience to grasp this very well. ”

Li Chao smiled and said, "To build a ship, it seems that we have to build a lumber yard and a timber processing plant first." The lumbermill is responsible for finding all kinds of qualified timber for shipbuilding, and then cutting and transporting it back to the processing plant. The processing plant then saws the trees into various planks according to the needs of shipbuilding, and then dries them. ”

Shipbuilding is a very systematic project that involves all aspects. Just like processed wood, when it comes to shipbuilding, some wood even has to be steamed, and then shaped to make an arc.

Keels and masts generally have to be spliced. Splicing involves a high level of technology, not simply splicing.

In the era of great exploration, the shipbuilding industry was extremely developed, and there was already a complete industrial chain. There are those who specialize in logging, those who specialize in processing ship timber, those who specialize in making sails, those who specialize in making anchors, those who specialize in the manufacture of cables, and even ship nails have special workshops.

In addition, artillery, etc., is basically outsourced.

The shipyard is only responsible for design and construction, and is more like a large assembly plant.

But now, if you want to build a boat, from beginning to end, almost all of it has to be done by the shipyard itself, and everything is all-inclusive. This model is the same as that of many workshops.

The downside is that it takes a long time.

Like traditional craftsmen, they take a few apprentices and work slowly from beginning to end.

And Li Chao has always liked industrialization, just like his family's industry, the introduction of assembly line operations everywhere, each product production, has long been divided into many processes, the masters only do the most difficult ones, the rest, try to use those apprentices and even ordinary workers to do.

That would greatly increase the speed and reduce the need for skilled workers.

Now to build a ship, Li Chao also plans to do this, to build a shipbuilding, decompose it into many projects, and build factories separately, now it can be smaller at the beginning, but the shelves have to be erected.

In this way, when a ship is built, it can be quickly scaled up and copied in large quantities.

"Timber mills can also introduce water-powered sawmills, which can be used to see wood with less effort."

"We can also build a hydraulic forging plant, so that we can use water power to forge anchors, which will also save a lot of effort."

Zhang Shan listened to Li Chao's thoughts, and could only keep nodding.

What logging yards, sawmills, anchor yards, nail factories, sail yards, cable yards, docks, etc., to build a ship, there are so many factories.

But it sounds really powerful.

"After the establishment of the Nanhai Commercial Bank, I hope that in ten years, our Nanhai Shipping Company will have at least 300 to 500 three-masted ships, and even more than 50 four- and five-masted galleons!"

When Zhang Sanyi heard Li Chao's grand goal, he couldn't help but be in awe, thinking about the appearance of four or five hundred ships moored in the harbor, he couldn't help but be very excited!

Lee Sang-ye is atmospheric! (To be continued.) )
