After Zhu Jingyuan finished writing his "idea", 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 electric furnace the future direction of industrial steelmaking?"
Zhu Jingyuan listened to this question and once again roughly confirmed in his heart that Emperor Shizu Zhu Cixiang was not very familiar with the industrial system.
He probably didn't even leave any directional information on the level of electric furnace steelmaking.
Therefore, the Ming Emperor did not specifically support electric furnace steelmaking, and currently it is completely laissez-faire.
Therefore, the current development status of electric furnace steelmaking in Ming Dynasty 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 Ming Dynasty's power generation capacity was generally relatively limited, and it had not yet used electricity to make steel on a large scale.
The electroslag remelting I requested has not yet appeared.
After I have given enough hints, it may take several years of exploration and optimization before it can be used to produce large-caliber naval guns.
When it truly matures, battleships may be eliminated.
However, if electric arc furnace technology is now available, we can recommend that the Ministry of Industry and the Royal Consortium work hard on electric arc furnaces.
There are already ready-made small-scale stoves. It is definitely simpler to design a larger-scale stove based on this than from scratch.
Electric arc furnaces also developed after World War II, and vacuum electric arc furnaces appeared, which are also high-grade steel production technologies.
It’s not in vain to start upgrading and promoting it now.
At the same time, even today's ordinary electric arc furnaces directly produce steel of better quality than traditional open-hearth furnaces.
Army artillery began to use arc steel in the late World War II.
The performance of large-caliber naval guns made by electric arc furnace steelmaking can definitely reach or exceed the performance of large-caliber naval guns in history.
As for the naval gun design specifications that I require, they can definitely be met.
So Zhu Jingyuan answered Zhu Zhongliang's question and made suggestions:
“Electric furnace steelmaking...should be the future development direction.
“The production principle of the electric furnace determines that it can smelt higher quality steel.
“But 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 types of electric furnaces, and the electroslag remelting furnace I envision can be used as a future-oriented research.
"Based on the existing electric arc furnace, we can continue to optimize the scale and try to use it to produce naval gun barrels."
After hearing this, Zhu Zhongliang handed back the document written by Zhu Jingyuan:
“In this case, then you should also write down these suggestions and remind them to focus on researching these two types of electric stoves.
“Also, since electric furnaces are the future development direction, the demand for electricity will also rise rapidly.
"There are no coal mines in Xintianfu. If we want to provide large-scale power supply, we can only build more hydropower stations..."
Zhu Jingyuan took the notebook and continued writing:
“Of course we can build more hydropower stations, which are relatively easy to use, but they cannot only use water and electricity.
“Coal is definitely needed, and coke is also needed for ironmaking.
“Coal can be transported from Beiyinzhou, and part of the coal-producing area in Beiyinzhou can be allocated to Huangzhuang for management.
“Try to develop the Yinzhou Oilfield and use petroleum gas, natural gas, and excess oil to generate electricity.
"Atomic power generation will also be developed in the future..."
Zhu Zhongliang nodded as he listened:
"When you go to Xintianfu, arrange all these things and build a steel plant in Xintianfu.
"As for the coal in Beiyinzhou, then the area east of Mi River and south of the Five Great Lakes will be designated as Huangzhuang and merged into Xintianfu.
“Beiyinzhou has been at war, and these areas are still under military control after they accepted it.
"The key point is that these are all negotiated by you. If you make suggestions to your father in your own name, he should not object.
"Even if the officials in the imperial court have objections, they can be suppressed with your merits."
After Zhu Jingyuan finished writing his industrial development suggestions, he immediately changed a piece of paper and continued writing his "suggestions."
After Zhu Jingyuan finished writing, he handed it to Zhu Zhongliang again to read first.
After reading this, Zhu Zhongliang nodded with satisfaction, and then thought of another question:
"You said before that electric furnaces are suitable for producing high-standard steel. Do you think we should continue to use open-hearth furnaces for ordinary steel?"
Zhu Jingyuan said directly:
"Open-hearth steel is not ordinary steel. Today's naval guns are made of open-hearth steel. Ordinary steel requires a converter."
Zhu Zhongliang said subconsciously after hearing this:
"The 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 "brew brewing".
Put an appropriate amount of scrap steel in the converter cup, and pour the high-temperature molten iron from the blast furnace into it.
Then add slagging materials, introduce oxygen into the furnace, shake it evenly and then pour it out, and the molten iron will become molten steel.
The whole process only takes ten minutes at the shortest, while refining it in an open-hearth furnace would take at least several hours, or even dozens of hours.
Converter steelmaking is a process where iron and steel are smelted at the same time, directly using the heat of molten iron and introducing oxygen to burn off excess carbon to complete steel smelting.
Steel itself is iron with a special carbon content. Once the carbon content of the molten iron is adjusted, the molten iron will become molten steel.
Therefore, converter steelmaking is faster and more energy-saving.
However, the quality of steelmaking in early converters was really poor, mainly because the composition of the air introduced was relatively complex.
It was not until after World War II that the production process was optimized again, and the air that was originally introduced 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 another plan to improve converter production.
“In fact, as long as the air blowing is changed to oxygen blowing, the quality problem of converter steelmaking should be solved.
“This idea should have been in place for a long time, but it is difficult to implement it.
"But with the advent of arc steel and electroslag remelted steel, these problems should be able to be solved."
Zhu Zhongliang nodded again with great satisfaction:
"Why don't you officially start writing a diary every day, and write down all the thoughts that come to your mind every day.
“You can take it out directly when you are ready to use it, 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 would be a serious person to write a diary...
But looking at Zhu Zhongliang's expectant expression, Zhu Jingyuan could only nod in the end:
"Okay, then I'll start writing a diary... I should say it's a record of my thoughts..."
Just keep a diary and keep yourself from forgetting.
After Zhu Jingyuan wrote these suggestions, he asked Chunxiang to send them to the confidential telegraph room of the palace, encrypt them and send 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 suggestions, the relevant personnel immediately translated them and forwarded them to the Ship Department and Ordnance Department.
Zhu Jingyuan and the Ministry of Industry have been cooperating for more than two years, and now the relevant agencies of the Ministry of Industry have a high degree of recognition for Zhu Jingyuan.
Zhu Jingyuan made various suggestions without delving into the reasons first, but directly conducted experiments.
While verifying the feasibility of the technology, slowly study and understand the technical principles.
Now they are all worried about naval guns and a series of problems. After seeing Zhu Jingyuan's suggestion, they immediately applied for a budget.
After Zhu Jianyan read Shizu's posthumous chapter, he had a higher degree of trust in Zhu Jingyuan's suggestions.
Now I see that the Ministry of Industry adopted the idea proposed by Zhu Jingyuan, and basically approved the permit without much consideration, and asked the Ministry of Industry and the Royal Consortium to cooperate in the project, and asked to expand the power plant to cooperate with electric furnace steelmaking.
So at the end of the second year of Ankang, a total of three battleship design and manufacturing industry chains were established in the two systems of the Ministry of Industry and the Royal Consortium. At the same time, high-intensity research on large-scale electric arc furnace steelmaking, electroslag remelting technology, and hydraulic self-tightening technology began. tackle key problems.
After Zhu Jingyuan finished writing the telegram, he accompanied Zhu Zhongliang to the "Product Exhibition Hall" to introduce and demonstrate to the old man various industrial products from Dashiguo and Mengxian Industrial Park.
The two stayed in the exhibition hall all morning. In the afternoon, Zhu Zhongliang rested in Bishui Garden, while Zhu Jingyuan went to check and deal with the matters that Wang Guoguo and Mengxian Industrial Zone were responsible for.
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 remaining half of the day dealt with the kingdom's official affairs as before.
Zhu Jingyuan soon discovered that when chatting with Zhu Zhongliang, he often accidentally said any new ideas, which would be captured by Zhu Zhongliang, and then he was asked to write them down and send them to the Ministry of Industry for discussion.
When this grandfather kept urging me, my speed in organizing and recording new technologies was much faster than before.
This is probably a good thing.
