Daming 1805

Chapter 287 Who is a serious person who writes a diary?
After Zhu Jingyuan finished writing his "thoughts", he first showed it to Zhu Zhongliang who was guarding outside.

Zhu Zhongliang sat directly opposite Zhu Jingyuan, read all the words very carefully, then raised his head and asked:
"Electric furnace? Is the future direction of industrial steelmaking electric furnace?"

Hearing this question, Zhu Jingyuan was roughly sure again in his heart that the ancestor emperor Zhu Cihong was not very familiar with the industrial system.

He probably didn't even leave any information on the direction of electric furnace steelmaking.

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

Therefore, the current development status of electric furnace steelmaking in Daming is also highly similar to the original development track in history.

Daming already had electric furnace steelmaking technology, including conventional resistance furnaces, induction furnaces, and electric arc furnaces.

However, the emperor did not specifically support it, and Daming's overall power generation capacity was relatively limited, and large-scale steelmaking with electricity had not yet been used.

The electroslag remelting required by oneself has not yet appeared.

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

When it is truly mature, battleships may be eliminated.

However, if the electric arc furnace technology is available now, it can be suggested that the Ministry of Industry and the Royal Consortium work hard on the electric arc furnace.

There are already existing small-scale furnaces, and designing a larger-scale furnace on this basis is definitely easier than starting from scratch.

Electric arc furnaces also developed after World War II, and vacuum electric arc furnaces appeared, which is also a production technology for high-grade steel.

It is not in vain to start the upgrade and promotion in advance.

At the same time, even the current ordinary electric arc furnace directly produces steel with better quality than the traditional open hearth furnace.

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

The performance of large-caliber naval guns manufactured by electric arc furnace steelmaking can certainly reach or even exceed the performance of large-caliber naval guns in history.

As for the design indicators of the naval gun that I require, it must be able to meet it.

So Zhu Jingyuan answered Zhu Zhongliang's question and at the same time made a suggestion:
"Electric furnace steelmaking...should be the future direction of development.

"The production principle of the electric furnace determines that it can smelt higher-quality steel.

"However, this production model also determines that its cost is relatively high and the smelting speed is relatively slow.

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

"However, there are many kinds of electric furnaces. The electroslag remelting furnace I envision can be used as a future-oriented research.

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

Upon hearing this, Zhu Zhongliang handed back the document written by Zhu Jingyuan:

"In this case, then you should also write these suggestions and remind them to focus on these two electric stoves.

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

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

Zhu Jingyuan took the notebook and continued to write:

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

"Coal is definitely needed, and ironmaking also needs coke.

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

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

"In the future, nuclear power generation will be developed..."

Zhu Zhongliang listened and nodded:

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

"As for the coal in Northern Yinzhou, the east of Mihe River and the south of the Five Great Lakes will be designated as Huangzhuang and merged into Xintianfu.

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

"The key point is that you negotiated these lands. If you use your own name to make suggestions to your father, he should not object.

"Even if the officials in the court have opinions, you can suppress them with your credit."

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

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

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

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

Zhu Jingyuan said directly:

"Open-hearth furnaces are not ordinary steel either. Today's naval guns are all made of open-hearth steel, and ordinary steel must use converters."

After hearing this, Zhu Zhongliang subconsciously said:

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

Converter steelmaking requires no energy.

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

A proper amount of scrap steel is placed in the converter cup, and the high-temperature molten iron from the blast furnace is poured into it.

Then add slag-making materials, pass oxygen into the furnace, shake it well and then pour it out, and the molten iron becomes molten steel.

The whole process takes only 10 minutes at the shortest, and it takes at least several hours, or even dozens of hours, to smelt it in an open hearth.

Converter steelmaking is iron and steel at the same time, directly using the heat of molten iron, passing in oxygen to burn off excess carbon, and completing steel smelting.

Steel itself is iron with a special carbon content. After adjusting the carbon content of molten iron, molten iron becomes molten steel.

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

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

After World War II, the production process was optimized again, and the original air was changed to oxygen.

Then, the quality of converter steelmaking improved rapidly.

Thinking of this, Zhu Jingyuan picked up the pen and paper again:
"Then let me think of a plan to improve converter production.

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

"This idea should have been made a long time ago, but it is difficult to realize it.

"However, after electric arc steel and electroslag remelting steel are available, these problems should be solved."

Zhu Zhongliang nodded again very satisfied:

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

"It can be taken out directly when it is used, and at the same time, the implementation sequence is planned step by step."

Hearing this strange request, Zhu Jingyuan raised his head in a strange mood. Who is a serious person to write a diary...

But seeing Zhu Zhongliang's expectant expression, Zhu Jingyuan could only nod in the end:

"Okay, then I'll start writing a diary...it should be said to be a record of thoughts..."

Keep a diary, just write a diary, and you can prevent yourself from forgetting.

After Zhu Jingyuan finished writing these suggestions, he asked Chunxiang to send them to the confidential telegraph room of the palace, and send them to the local Ministry of Industry of the Ming Dynasty after encrypting them.

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

After receiving the latest suggestion, the relevant personnel immediately translated it and handed it over to the Ship Department and the Ordnance Department.

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 high degree of recognition of Zhu Jingyuan.

All kinds of suggestions made by Zhu Jingyuan will not go into the why first, but go directly to the experiment.

While verifying that the technology is feasible, slowly research and understand the technical principles.

Now they are all worrying about naval guns and a series of problems. Seeing Zhu Jingyuan's suggestion, they immediately applied for the budget.

After Zhu Jianyan read the legacy of the ancestors, he trusted Zhu Jingyuan's suggestion even more.

Now seeing that the Ministry of Industry took the idea proposed by Zhu Jingyuan, it directly approved the permit without much consideration, and asked the Ministry of Industry and the Royal Consortium to cooperate with it, and asked to expand the power plant to cooperate with electric furnace steelmaking.

So at the end of the second year of Ankang, within the two systems of the Ministry of Industry and the Royal Consortium, a total of three warship design and manufacturing industry chains began to be developed at the same time for large-scale electric arc furnace steelmaking, electroslag remelting technology, and hydraulic self-tightening technology. Tackling key problems.

After Zhu Jingyuan finished writing the telegram by himself, he accompanied Zhu Zhongliang to the "product showroom" to introduce and show the old man various industrial products of Dashiguo and Mengxian Industrial Park.

The two stayed in the exhibition hall all morning. In the afternoon, Zhu Zhongliang took a rest in the Green Water Garden, and Zhu Jingyuan went to check and deal with the main things that Wang Guo and Meng County Industrial Zone had visited by himself.

In the last month of the second year of Ankang, Zhu Jingyuan basically spent half the day exercising, chatting, and walking with his grandfather, and the rest of the day dealt with the kingdom's official duties as usual.

Zhu Jingyuan soon discovered that in the process of chatting with Zhu Zhongliang, he often accidentally expressed some new ideas, which would be caught by Zhu Zhongliang, and then he was asked to write them down and send them to the Ministry of Industry for trouble.

When this grandpa kept urging him by his side, his speed of sorting out and recording new technologies was much faster than before.

This is probably a good thing.

　The routine of work and rest is completely messed up again...
