Daming: I help my wife be the empress

Chapter 168 Ironmaking technical support from later generations

Huang Yuanchang had the courage to come out to remind this matter, in fact, he wanted to show that he was sincerely for the good of Jian Guo Fu.

Because it is Zhu Yuxi who controls the property of the King of Shu now, and it is the Jianguo Mansion, so the minerals of the former Shu King Mansion actually belong to Zhu Yuxi now.

You must know that the reason why the Shu king family is so rich has a lot to do with the rich minerals such as gold, silver, copper, iron and precious stones in Chengdu and its surrounding areas.

Huang Yuanchang thought that Auntie Zhu didn't know about this, so she proposed to cancel the tax-free privilege of mining.

Unexpectedly, after hearing this, Auntie Zhu's expression remained unchanged and she said: "Of course, the Shu Palace will cancel the tax-free privilege of mining. From now on, under the rule of this palace, anyone who mines or smelts will have to pay taxes!"

Hearing this, Huang Yuanchang was stunned for a moment, thinking to himself: How much is the normal tax payment for so many minerals a year?

Immediately afterwards, I suddenly thought: No, didn't these taxes still go to the Jian Guo Mansion in the end?
No wonder.

Huang Yuanchang thought he understood Aimi Zhu's thoughts, so he returned to his original position and stopped talking.

However, Li Yan and Liu Linchang understood that the property controlled by the Shu Palace or Zhu Yuxi was somewhat different from that controlled by the Jian Guo Mansion.

Both of them admire Aimi Zhu for being willing to set such an example.

So they said together: "Jianguo is wise!"

Aimee Zhu was very indifferent, and went directly to the next topic.

"In addition to reforming the management system of iron mines and iron factories, what we need to do is to improve the level of iron and steel smelting and production efficiency.

Fei Sibo distributed the "Suggestions for Ironmaking and Steelmaking" written by the concubine. "

Upon hearing this, Fei Zhen'e picked up a stack of A4-bound booklets from the desk and distributed them.

When Li Yan, Liu Linchang, and Li Zuo looked through it, Zhu Wei introduced, "Here are some suggestions from my son-in-law regarding our existing iron-making and steel-making technologies in Ming Dynasty.

Li Zong and the two ambassadors of the Military Weapons Bureau should have some understanding of my Daming iron and steel making technology, right?

After reading it, let me tell you that the suggestions in this booklet are practical and where there are mistakes.

If there is anything you don't understand, you can also ask me.Be sure to understand the above technology today, and then set up a blast furnace experiment in Chengdu.

After the experiment is successful, it will be used in the government-run iron factories in Chengdu and Qiongzhou, so as to improve the quality and output of steel in these two places as soon as possible. "

"Yes."

Li Zuo, Huang Yuanchang, and Zheng Xiang agreed, and looked more seriously.

Although they are not craftsmen, they are all in charge of armament manufacturing all year round, so they naturally have some understanding of Daming iron and steel technology.

Knowing that the above suggestions were all put forward by the son-in-law of "Immortal Realm", the three of them were a little afraid that they would not understand.

But after looking inside, the three of them discovered that the suggestions put forward by the son-in-law were basically breakthroughs and improvements aimed at Daming's existing technology.

That is to break through a layer of paper with the existing technology of Ming Dynasty and upgrade it to a higher level.

Not only could they understand it, but they couldn't help but beam with joy when they watched it, and they almost couldn't hold back their joyful shouts in the Chengyun Hall.

Although Li Yan and Liu Linchang didn't know much about steel smelting technology, they were smart people.

Therefore, it can be seen how much the above suggestions have helped to improve the smelting level of Daming Iron and Steel.

After a while, it was Li Zuo who finished it first.

I saw him holding the booklet and going out, excitedly said: "Jianguo, I have already read it, the suggestions above are not only practical, but also very helpful to improve our steel smelting level.

As long as it is implemented in the iron factory, the existing steel production can be increased by at least ten times, or even dozens or even hundreds of times! "

Aimee Zhu was also very happy to hear that the suggestions listed by Hao Guangming were approved by the technical officials under him.

With a smile on her lips, she finished reading Huang Yuanchang and Zheng Xiang, and asked, "What do you two ambassadors think?"

Huang Yuanchang said: "Li Zong is right. This suggestion can at least increase steel production by ten times."

Zheng Xiang followed suit.

The two of them didn't want to flatter this time, but sincerely admired it.

Regardless of the dismantling of the government-run iron factories in the late Ming Dynasty, the private iron factories were very prosperous. Compared with the Song and Yuan Dynasties, the level of iron and steel smelting can be said to have made great progress, completely ahead of other countries in the world.

For example, the use of piston blowers has the same structure and function as modern blower equipment, but Europe did not have such inventions until the late eighteenth century.

Another example is the technology of "smelting wrought iron and pig iron into steel in a crucible", which also did not exist in Europe until the eighteenth century.

Another example is the "raw and cooked iron-making furnace" recorded in "Tiangong Kaiwu", which skillfully connects the iron-making furnace and the steel-frying furnace together, and has realized semi-continuous production of steel and small-scale mass production.

In addition, such as Sugang's steel pouring smelting technology and pig iron spouting technology, etc., were unique in the world in the seventeenth century.

Although these technologies were not fully spread in Daming, they were all invented and created by Daming craftsmen.

In addition, the efficiency of folk ironmaking is not low. Among them is a kind of bottle furnace, which is quite large. One furnace can smelt 3600 catties of iron overnight, and more than 6000 catties a day!

And the scale of the ironworks is not small, not to mention the government-run ironworks, many of which can reach thousands of people.Even some private iron factories in the south have thousands of people.

The smelting level of these iron factories around Chengdu may not have reached the top level of Ming Dynasty, but because of this, they can get more improvement from Hao Guangming's "suggestion".

For example, a high-refractory brick is mentioned in the proposal, which can be made of rich refractory materials (high-alumina clay) in Pujiang, Dayi, Pengzhou and other places, and can be directly used in the construction of steelmaking furnaces. Firestone is much stronger for building a furnace.

(Steelmaking temperature must exceed 1600°C, while high refractory bricks made of high alumina clay can withstand high temperatures of 1700 to 1800.)
Another example is the improvement of iron-making furnaces, steel-making furnaces, and blowers, which can make the iron and steel obtained from each furnace better in quality and higher in output.

In addition, it also proposed to establish a hydraulic forging hammer to replace artificial forging iron into steel.

As for standardizing the smelting process to improve production efficiency, it was naturally mentioned.

In the opinion of Li Zuo and the others, although it is not easy to implement the various suggestions in this suggestion list, they are indeed operable.

And once it is implemented, as they said, it is not impossible to increase steel production by at least ten times, or even tens or hundreds of times.

After listening to Huang Yuanchang and Zheng Xiang's words, Auntie Zhu smiled even wider, and said, "Since you all think it is feasible, let's discuss how to implement these suggestions."

"Yes!"

···
In order to improve the level of iron and steel smelting in the Iron Works under his administration, Zhu Yu held a whole day's meeting.

Afterwards, she didn't care about the specific implementation—if she was required to handle the following matters, what would be the use of Li Zuo and other officials in charge of specific affairs?

The next day.

Aunt Zhu took Liu Linzhang to inspect the Military Weapons Bureau, because she was going to transfer people from the Military Weapons Bureau to build a military factory.

After the inspection, when they returned to the Chengyun Hall, Zhu Wei handed a brochure to Chief Liu Lin and said, "This is the brochure for the establishment of an arsenal, Assistant Manager Liu, let's take a look."

Liu Linchang is used to Auntie Zhu taking out an A4 bound booklet every now and then, even getting used to reading it horizontally.

In addition, this booklet didn't have many pages, so he read it quickly, and then he was full of admiration.

"The 'realization of production tools and product standardization', 'assembly line production', and 'large-scale use of hydraulic machinery' mentioned in this booklet are all wonderful ways to improve the efficiency of armament production."

Aunt Zhu said with a smile: "These methods are all learned by the son-in-law from later generations, so they are naturally wonderful methods.

What Liu Xieli needs to consider is where the arsenal should be built and how to implement these magic methods to improve the efficiency of armament production as soon as possible. "

After hearing the words, Liu Linchang thought for a while and said: "We can build an arsenal by the Jiang'an River in the western suburbs of the city. The Jiang'an River is connected to Dujiangyan on the upper side and Jinjiang and Minjiang Rivers on the lower. Whether it is large-scale use of hydraulic machinery or transportation of raw materials such as coal and iron. convenient."

　Chapter 166 has not been unsealed, so I am speechless.This chapter is basically about the reform of iron ore management.

　　Let me tell you here first.

　　I just hope that everyone will remember to subscribe again after it is released, otherwise it will definitely be pulled down a lot.

　　To make up, there is another chapter tonight.

　　[Supplement: I think there are still readers struggling with the sustainable development issue raised by Liu Lin in Chapter 165. This issue is naturally clarified in Chapter 166.Simply put, it means that the strength is stronger, and the resources outside Daming are used to produce, and the resources inside Daming are kept.In addition, the scale of ironmaking in the early stage has not fully increased, so it will not consume too many resources. 】
