Daqingshan Mine. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

This is an open-pit mine, open-pit mining, at least hundreds of people are working, and the sound of clanging mining is constantly coming, and it is lively.

The iron ore was immediately waiting to be transported, and there were already some ox carts, horse-drawn carts, wheelbarrows, etc., and even some porters, who were ready to transport the iron ore to the wharf about ten miles away.

Today, Zhang Feng took the time to come to the Daqingshan mine.

Accompanied by Yang Shenghai, Zhang Feng took a boat along the Yangtze River and arrived at the wharf not far from the mine.

Although the mining efficiency is a little low due to the limitation of the level of productivity, hundreds of people work every day, and a lot of iron ore is mined, which is loaded on ships, down the river, and finally transported to the Baoshan Iron and Steel Plant.

Yang Shenghai said happily: "Boss, take a look, this side is full of iron ore mined by us, and the quality is very good." ”

There was a large pile of iron ore in front, Zhang Feng picked up a piece, feeling heavy, Zhang Feng said happily: "From now on, we don't have to worry about the shortage of refined iron." ”

In the past, there was no iron and steel factory of its own, and it needed refined iron, so it could only be purchased at a high price from the government, and it was necessary to manufacture fine iron for flintlock muskets and steam engines.

Now, with our own mine and our own steel plant, all problems will be solved.

Zhang Feng said: "Lao Yang, have you done everything in the Taiping Mansion?" ”

The Ming Dynasty implemented a monopoly on salt and iron, Zhang Feng's large-scale mining, naturally through the government, fortunately, at the end of the Ming Dynasty, the management of salt and iron has been very relaxed, a large number of salt merchants have long appeared, and the iron smelting is basically the same, as long as there is money, a little bit of it, mining and iron smelting is not a big problem.

Yang Shenghai said: "Boss, it has already been sorted out, and after receiving our silver, the Taiping Mansion is very happy." ”

Zhang Feng smiled, it is not a big deal to settle with silver, Zhang Feng said happily: "With iron ore, our Baoshan Iron and Steel Plant will also open a furnace to make steel." ”

Yang Shenghai is also happy, preparing to build Baoshan Iron and Steel Plant, Yang Shenghai has paid a lot of hard work and energy, and now, there will be results soon.

Opening the furnace to make steel, Yang Shenghai is very much looking forward to it.

Yang Shenghai said: "Boss, open the furnace to make steel, we will have our own steel." ”

Zhang Feng nodded: "Not only do we have our own steel, but soon, we will also have our own transport ships, and the transportation efficiency will be multiplied." ”

Now the iron ore transportation, mainly with the kind of cargo ships of the people, large and small, belonging to sailboats, there are also manpower paddle manpower cargo ships, fortunately, the transportation of iron ore is downstream, otherwise, enough choking.

Even if it is downstream, those cargo ships of the people, where can they compare to steam-powered cargo ships, Yang Shenghai has heard of this kind of steam-powered cargo ships, but he has never seen them, and he is very curious.

Yang Shenghai said: "Boss, steam-powered cargo ships, really don't use sails, is it really that good?" ”

Zhang Feng said confidently: "Of course." ”

Steam-powered cargo ship!

Zhang Feng's heart also looked forward to it, this is the world's first steam-powered cargo ship, designed by Zhang Feng's hand, on the basis of the 2,000 Zheng He treasure ship, added steam power, completely canceled the sails, and did not use manpower oars.

………

Shanghai Shipyard.

Among the two docks, two cargo ships are being built at the same time, both of which are Zheng Hebao's 2,000-material ships, that is, transport ships with a displacement of 1,000 tons.

Tang Jianqing was inspecting his beloved baby as if he was inspecting his beloved baby, and he also told everyone from time to time that they must pay attention to quality and be in place.

It has to be said that the shipbuilding technology of the Ming Dynasty has developed to a very high level, like the two 2,000 treasure ships under construction, which belong to the ocean-going ship type, adopting a structure of "sharp bottom and wide top", with a high bow and stern.

The hull structure is provided with a plurality of transverse bulkheads, and a whole cabin is divided into a plurality of small cabins according to function, up to 28 cabins, which not only has the effect of strengthening the structure and sub-compartment watertight and anti-sinking, such a structure, so that the ship can develop to large-scale, but also conducive to the division of compartments to classify cargo, to meet the requirements of the use of different functions.

I have to say that Zhang Feng really picked up a treasure, and Tang Jianqing's attainments in shipbuilding even greatly exceeded Zhang Feng's estimates.

Tang Jianqing not only has a family history, but also a detailed shipbuilding atlas and shipbuilding technology handed down by his ancestors, and Tang Jianqing's own shipbuilding level is very high.

Under the guidance and supervision of Tang Jianqing, these two 2,000-material ocean-going treasure ships have been the same every day, and now they have basically taken on a rudimentary form.

The 2,000-material sea-going ship adopts an all-wood structure. In the Ming Dynasty, the shipbuilding technology developed to include shovel nails, iron shovels, shovel nails, leech nails, etc., so that the complex wooden structure can be easily assembled, hung and reinforced together through various ship nails, so as not to "fall apart".

These two 2,000 treasure ships, the same inheritance and use of the above technology, in addition to these, also used bolts, such as in addition to the mortise and tenon joint, many places use bolt connection.

After seeing the bolt, Tang Jianqing admired Zhang Feng more and more, in Tang Jianqing's view, this is a big technological innovation, with the bolt, not only the ship is stronger, but also the construction of larger ships is easier.

Tang Jianqing inspected the construction situation on the ship, and several young men who were building ships next to him were all from the leading shopkeeper household, and the entire shipyard was basically based on the craftsmen of the leading shopkeeper household camp, and appropriately recruited some craftsmen from all over Songjiang Prefecture.

One of the young men asked loudly: "Donald, this thousand-material treasure ship has no mast, no sails, and no oars, and this ship can be driven." ”

Tang Jianqing is also very much looking forward to steam power, since listening to Zhang Feng's description, Tang Jianqing has often wondered when these two thousand treasure ships will be equipped with steam power.

Tang Jianqing said: "You will know when the time comes, now you just need to build the ship as required." ”

These two treasure ships will be equipped with steam power.

Although it is the world's first batch of steam pneumatic ships, but because the design is from Zhang Feng's hand, and there is Tang Jianqing's guidance and control in the process, these two ships are definitely no worse than the first steam-powered ship in history, in 1807, Fulton of the United States made the first practical paddle wheel propulsion steam engine ship "Clermont".

The Clermont used paddle wheels, while Zhang Feng's steam-powered treasure ship used propellers, a huge technological advance.

Tang Jianqing was full of confidence in Zhang Feng, and looked forward to the import and installation of steam power on these two treasure ships and the launching of the sea trial as soon as possible.

………

It's hard for a good woman to cook without rice!

Now, Zhang Feng deeply realized this, although he tried his best to get another two or three thousand catties of refined iron, but the materials were still exhausted, and the entire Xiaoqingshan Arsenal had no refined iron, and the material warehouse was even more empty.

Fortunately, some time ago, a little bit of flintlock muskets were finally made, and more than 1,000 wooden-handled grenades were made, but the development of the steam engine was about to stop.

In the huge workshop, there is no longer the busyness of the past, the craftsmen have been on vacation since yesterday, and they have worked hard for several months, and suddenly have a five-day holiday, the craftsmen are naturally happy, but Zhang Feng is not in a good mood.

In a manufacturing workshop.

Zhao Zuolin had a sad face, and was pouring bitter water on Zhang Feng, "Boss, all the fine iron has been used up, and our big steam engine can't go on." ”

This steam engine, compared with the last time is much larger, but also more complicated, on the basis of the first steam engine to carry out a series of technical improvements, the use of separate condenser, the cylinder outside the setting of thermal insulation layer, oil lubrication piston, planetary gear, parallel motion linkage mechanism, centrifugal governor, throttle valve, pressure gauge, etc., so that the efficiency of the steam engine compared with the first steam engine increased by as much as 3 times.

Of course, the steam pressure is also higher, the output power is more powerful, the first steam engine, only a small steam engine, and a relatively simple structure, Zhao Zuolin and others, by hand, knock and beat, under the guidance of Zhang Feng, took half a month to manufacture, and the quality is not bad.

The maximum power of the first steam engine was only a dozen horsepower, while this steam engine was much larger, with a maximum output of more than 200 horsepower and a weight of several thousand catties.

However, this thing is big, not only large in size and power, but also needs a lot of refined iron, because the refined iron is used up, this steam engine only manufactures some key parts, and other parts can no longer be manufactured without refined iron.

Such a big guy, high technical content, is a challenge for Zhao Zuolin and others, fortunately, Zhang Feng has fully considered the process, and has also done the soldiers and horses have not moved, the grain and grass first, several machine tools designed by Zhang Feng himself have been manufactured for most of the time.

These machine tools, no longer wooden structure of the machine tool, than the wooden structure of the inspection is slightly more complex, more advanced, the accuracy is further improved, although and modern lathes can not be compared, but should be close to the level of modern machine tools, Zhang Feng estimates, these machine tools if manufactured, should be comparable to the level of machine tools in the early nineteenth century.

The machine tool has been greatly improved, the bed is made of cast iron structure, and the power is steam pneumatic power, that is to say, it is driven by a steam engine, and the level of technical content is absolutely far ahead in this era, but the manufacturing of these machine tools is the same, because there is no fine iron, and the shutdown is declared.
