After Zhu Jingyuan finished writing his "thoughts", he first showed Zhu Zhongliang, who was guarding outside.

Zhu Zhongliang sat directly opposite Zhu Jingyuan, read all the words very carefully, and then looked up and asked:

"Electric stove? Is the direction of industrial steelmaking in the future electric furnace? ”

Zhu Jingyuan listened to this question, and once again roughly determined in his heart that Emperor Zhu Cihong was not very familiar with the industrial system.

It is likely that he did not even leave information on the direction of electric furnace steelmaking.

Therefore, the Ming Emperor did not specifically support electric furnace steelmaking, and it is currently completely laissez-faire.

Therefore, the current development status of electric furnace steelmaking in Daming is also highly consistent with the original development trajectory in history.

Daming already has electric furnace steelmaking technology, including conventional resistance furnaces, induction furnaces, electric arc furnaces, etc.

However, the emperor did not have special support, and the power generation of the Ming Dynasty was relatively limited overall, and large-scale electricity was not used to make steel.

The electroslag remelting requested by itself has not yet appeared.

After giving enough hints yourself, it may take several years of exploration and optimization before it can be used to produce large-caliber naval guns.

When it really matures, the battleships may all have to be eliminated.

However, if the electric arc furnace technology is now available, it is possible to suggest that the Ministry of Industry and the Royal Foundation work on the electric arc furnace.

There are already ready-made small-scale stoves, and designing a larger scale furnace on this basis is certainly simpler than starting from scratch.

Electric arc furnaces also developed after World War II, with the emergence of vacuum electric arc furnaces, which are also the production technology of high-grade steel.

It's not in vain to start upgrading and promoting it in advance.

At the same time, even if it is an ordinary electric arc furnace now, the quality of the steel produced directly is better than that of the traditional open-hearth furnace.

Army artillery in the late World War II began to use arc steel.

The performance of large-caliber naval guns made of steelmaking with electric arc furnaces can definitely reach or even exceed the large-caliber naval guns in history.

As for the design indicators of the naval guns required by themselves, they will definitely be able to meet them.

So Zhu Jingyuan answered Zhu Zhongliang's question and made suggestions at the same time:

"Electric furnace steelmaking...... It should be the way of the future.

"The production principle of the electric furnace dictates that it is able to smelt higher quality steel.

"But this mode of production also determines that its cost is relatively high and the smelting speed is relatively slow.

"Therefore, it is suitable for the production of high-standard special equipment, such as artillery barrels, barrels, bearings, large rotors, etc.

"However, there are many types of electric furnaces, and the electroslag remelting furnace I envisioned could be used as a future-oriented research.

"On the basis of the existing electric arc furnace, we can continue to optimize and scale up and try to use it to produce naval gun barrels."

Zhu Zhongliang listened and handed back the document written by Zhu Jingyuan:

In that case, you should also write these suggestions and remind them to focus on these two types of electric stoves.

"In addition, since electric furnaces are the future development direction, the demand for electricity will also rise rapidly.

"There are no coal mines in Xintianfu, and if you want large-scale power supply, you can only build more hydropower stations......

Zhu Jingyuan took the book and continued to write:

"Of course, we can build more hydropower stations, which are still relatively easy to use, but it is impossible to use only hydropower.

"Coal is definitely needed, and coke is needed for ironmaking.

"Coal can be transported from North Yinzhou, and part of the coal production area in North Yinzhou will be allocated to Huangzhuang for management.

"Try to develop the Yinzhou oil field and use petroleum gas, natural gas, and excess oil to generate electricity at the same time.

"In the future, we will develop a ...... for nuclear power generation"

Zhu Zhongliang listened and nodded:

"When you go to Xintianfu, arrange all these things, and build a steel plant in Xintianfu.

"As for the coal in North Yinzhou, then the east of the Honey River and the south of the Great Lakes will be divided into Huangzhuang and incorporated into Xintianfu.

"Northern Yinzhou has been fighting, and these areas are still under military control after they have been accepted.

"The key is that you have negotiated these places, and if you make suggestions to your father in your own name, he should not object.

"Even if the officials in the court have opinions, they can use your credit to suppress them."

After Zhu Jingyuan finished writing his industrial development proposal, he immediately changed the paper and continued to write his "proposal".

After Zhu Jingyuan finished writing, he handed it to Zhu Zhongliang again to read first.

Zhu Zhongliang nodded with satisfaction after reading it, and then thought of another question:

"You said before that electric furnaces are suitable for producing high-standard steel, so do you continue to use open-hearth furnaces for ordinary steel?"

Zhu Jingyuan said directly:

"The open-hearth is not ordinary steel, the current naval guns are made of open-hearth steel, and ordinary steel has to use converters."

Zhu Zhongliang listened and subconsciously said:

"Converter...... The speed of the converter is indeed fast, but the quality is really not good. ”

Converter steelmaking does not require energy.

The converter itself can be seen as a "cup", and the steelmaking process can be seen as a "brewing drink".

Put an appropriate amount of scrap steel in the converter cup, and pour the high-temperature molten iron flowing from the blast furnace into it.

Then add slag material, introduce oxygen into the furnace, shake it well, and then pour it out, and the molten iron will become molten steel.

The whole process only takes ten minutes at the shortest, and it takes at least several hours, or even dozens of hours, to refine it with an open-hearth.

Converter steelmaking is to directly use the heat of molten iron to burn off excess carbon with oxygen at the same time to complete steel smelting.

Steel itself is iron with a special carbon content, and after adjusting the carbon content of molten iron, the molten iron will become molten steel.

Therefore, the converter steelmaking speed is fast and more energy-efficient.

However, the quality of early converter steelmaking is really not good, mainly because the composition of the air introduced is relatively complex.

It was not until after World War II that the production process was optimized again, and the original air was changed to oxygen.

Then, the quality of converter steelmaking has improved rapidly.

Thinking of this, Zhu Jingyuan picked up the pen and paper again:

"Then I'll think of a plan to improve converter production.

"In fact, as long as the blowing air is changed to blowing oxygen, the quality problem of converter steelmaking should be solved.

"This kind of idea should have been in place for a long time, but it is difficult to implement.

"But with arc steel and electroslag remelting, we should be able to solve these problems."

Zhu Zhongliang nodded with great satisfaction again:

"You might as well start writing a diary every day, and write down all the thoughts that you can't think of every day.

"When you use it, you can take it out directly, and at the same time, you can plan the implementation sequence step by step."

When Zhu Jingyuan heard this strange request, he raised his head in a strange mood, who writes a diary seriously......

However, looking at Zhu Zhongliang's expectant expression, Zhu Jingyuan could only nod in the end:

"Okay, then I'll start journaling...... I guess it's a record of ideas......"

Keep a diary, just keep a diary, and you can avoid forgetting yourself.

After Zhu Jingyuan wrote these suggestions, he asked Chunxiang to send them to the confidential telegraph room of the palace, encrypted them, and sent them to the Ministry of Industry of the Ming Dynasty.

The Ministry of Industry has a special agency responsible for receiving Zhu Jingyuan's various opinions.

After receiving the latest proposal, the relevant personnel immediately translated it and forwarded it to the Naval Department and the Ordnance Division.

Zhu Jingyuan and the Ministry of Industry have cooperated for more than two years, and now the relevant institutions of the Ministry of Industry have a very high degree of recognition of Zhu Jingyuan.

Zhu Jingyuan's various suggestions will not first delve into why, but directly go to experiments.

While verifying the feasibility of the technology, slowly study and understand the technical principles.

Now they are all worried about naval artillery and a series of problems, and when they see Zhu Jingyuan's suggestion, they immediately go to apply for a budget.

After Zhu Jianyan read the last chapter of the ancestor, his trust in Zhu Jingyuan's suggestion was also higher.

Now I saw that the Ministry of Industry was taking Zhu Jingyuan's idea, and basically approved the license without much consideration, and asked the Ministry of Industry and the Royal Consortium to cooperate with each other, and asked to expand the power plant in order to cooperate with electric furnace steelmaking.

Therefore, at the end of the second year of Ankang, a total of three warship design and manufacturing industrial chains were carried out in the two systems of the Ministry of Industry and the Royal Consortium, and at the same time, high-intensity research on large-scale electric arc furnace steelmaking, electroslag remelting technology, and hydraulic self-tightening technology began.

After Zhu Jingyuan finished writing the telegram himself, he accompanied Zhu Zhongliang to the "product exhibition hall" to introduce and display various industrial products of Da Shiguo and Mengxian Industrial Park to the old man.

The two stayed in the exhibition hall for a morning, and in the afternoon Zhu Zhongliang rested in Bishui Garden, and Zhu Jingyuan went to inspect and deal with the affairs of the Kingdom and Mengxian Industrial Zone.

In the last month of the second year of Ankang, Zhu Jingyuan basically spent half a day exercising, chatting, and walking with his grandfather, and the remaining half a day was used to deal with the official affairs of the kingdom as before.

Zhu Jingyuan soon found that in the process of chatting with Zhu Zhongliang, he often accidentally said any new ideas, which would be captured by Zhu Zhongliang, and then asked to write them down and send them to the Ministry of Industry to toss.

When this grandfather was constantly urging by his side, he sorted out and recorded new technologies much faster than before.

That's probably a good thing.
