How many workshops are there in Shuntian at dusk?

There are workshops that develop cement, which are now mass-produced. Due to transportation, the production speed is slightly slow and can only meet the construction outside the customs.

This is far from enough.

It has been built outside the pass, isn’t it built inside the pass?

So Wu was sure that when he returned to Yingtian this time, Zhu Di would force him to express his opinion and help him establish the official roads of Yingtian to Shuntian and the important towns around these two capitals.

Of course, dusk will definitely be rewarded from Zhu Di.

He would be "forced" to allow the construction engineering company under Huawei real estate to contract the reconstruction and expansion of all official roads in the Ming Dynasty, well, not including Shuzhong.

It is too painful to build roads in Shuzhong.

Anyway, the population of Ming Dynasty was not large, so it would be better to migrate the population of remote villas and concentrate them together, and then return to breed with the advancement of science and technology.

The research and development of cement depends on the emergence of simple ball mills - Shuntian Ball Mill Workshop has developed the simplest human ball mill, and continues to invest money at dusk to let them consider other power settings, such as hydraulics and electricity.

But electricity is very complicated and requires electric motors. This matter requires you to ask the technicians in the ball mill workshop to hold a "technical" meeting, determine the general direction, and find talents at home and abroad to solve problems.

After thinking about it, it would be better to set up a motor research and development department directly.

The hydraulic power is simple.

Before the motor was invented, we would use a hydraulic ball mill for a few years. After all, even if we invest heavily in research and development, it would be difficult to get out the motor for less than five or even decades.

The emergence of human ball mills is due to the technological progress of Shuntian’s steelmaking workshop. "Special steel" with barely qualified performance has been developed. Because the performance is barely qualified, the ball mills have extremely large losses and extremely high replacement rate, so the cost is also huge.

So after dusk arrived, we continued to invest heavily in improving superhard special steel, and allowed steel mills to continue to develop special steel with other performance. In short, we should come up with our own ideas to drive progress by letting economic and industrial demands drive progress.

That's all that can be done at dusk.

On the hydropower side, we encountered a bottleneck... mainly because the voltage stability cannot be controlled. The technicians have been working on it for two or three years, but still have not found a solution.

After the evening patrol, I slapped my head and was very upset.

It's your fault!

After establishing this hydropower research and development workshop, one thing was ignored because of being too busy: the power generated by hydropower is huge, involving the conversion of high and low voltages and long-distance power transmission.

In fact, it's just a transformer problem.

No matter how much a hydropower station is, it must be several miles away. For the city's planning and development, it must be at least dozens of miles away, so it involves the solution to the transmission voltage.

The principle of a transformer is simple: a transformer uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core. The secondary coil is outside the primary coil. When the primary coil is connected to AC power, the transformer core generates an alternating magnetic field, and the secondary coil generates an induced electromotive force.

This is found in physics textbooks in junior high school.

Although it is simple, electricity is an epoch-making product for the Ming Dynasty. No matter how technicians can think of it, they cannot think of this problem, so they cannot create a transformer.

After inspecting the hydropower research and development workshop at dusk, I spent another day discussing with a group of technical backbones for a whole day, explaining the principle of the transformer in detail, and then taking the time to draw a design schematic for them.

The following is to solve the problem of loss during power transmission - the oil industry has not developed, which means there is no plastic. So what can isolate the wires to ensure the safety of power transmission and reduce losses?

It is definitely not feasible to use porcelain pipes. The porcelain pipes are too heavy between long-distance electric piles.

Use paint?

It is low in safety and does not seem to reduce much loss.

After thinking about it, I finally decided to choose rubber.

Rubber is a specialty of Malaysia. In the Ming Dynasty, it was basically a rich man in the Siam-based Manlacca Kingdom. With the development of overseas trade in the Song and Yuan dynasties, although the Ming Dynasty forbidden seas, rubber was still spread.

After choosing rubber at dusk, I immediately had an idea: Zheng He has returned from his second voyage to the West, and he will prepare for his third voyage to the West this year, so that Zheng He can bring a lot of rubber back.

After thinking about it again, the routes will be paved across the country in the future, and what Zheng He brought back will definitely not be enough.

This problem must be fundamentally solved.

Two plans: First, this time, when you return to Yingtian, no matter what, even if it violates the interests of all officials, the Ming Dynasty must reopen the shipping line so that it can be used for foreign use.

2. Introduce rubber trees to fundamentally solve the problem.

The introduction of rubber trees can not only provide a variety of materials, but also provide progress for horse-drawn carriages, and provide emerging industries and employment opportunities for the people in the Ming Dynasty.

Well, this matter can be considered to be implemented at the same time on Jiaozhi.

Let Jiaozhi plant large quantities so that the people of Jiaozhi can appease the people of Jiaozhi. As for the people of Ming Dynasty, honestly enjoy the benefits brought by industrial changes is to be an "American" in advance.

Thinking of this dusk, I had an idea and told the person in charge of the hydraulic R&D workshop to set up a transmission line R&D department to buy rubber at any cost in the market, and experiment with how to turn rubber into a pipeline design that wraps the line.

Then, Shen Xili was found again in Dusk.

The workshops established have made great progress, but the development of industry is far from being driven by several workshops in full. Other industries are also needed, the most important industry is the oil and coal industry.

This must be put on the agenda.

For the Ming Dynasty, mining is a problem. The current solution is to purchase from abroad. This is a long-term problem. Oil tankers are needed, and oil tankers need huge power equipment. The Ming Dynasty does not have the technology at present and needs to wait for the engine and steelmaking industry to continue to improve. However, we can prepare for the future and use the Ming Dynasty's merchant ship leading the world to buy barrel oil and return to do industrial research and development.

The second is coal, and we must increase the use of coal.

Finally, at dusk, he took out a design drawing of a carriage he drew on the grassland and handed it over to Shen Xili, asking him to set up a department, carefully study and improve according to this design drawing, and then put it into production.

This rail carriage is not difficult.

In fact, it is an upgraded version of the carriage, mainly because the bearing needs to be claimed by the steel industry. Fortunately, the steel used in the ball mill is super hard steel, which is competent for the use of bearings.

Therefore, this product can be put into production in about half a year at most.

Shen Xili was amazed.

Of course, Shen Xili's shock came not only from the carriage, but more importantly, he was following the evening these days and watching the flourishing of these workshops, he saw a brand new world.

Then I have a feeling.

crazy.

Too crazy.
