Although there are many rare crystals in Dali, they are still subject to state control, and like many ores such as iron ore and copper ore, they belong to the imperial court.

It is mainly used for smelting in the imperial court, and can be purchased in limited quantities in private iron foundries and kilns......

In the past, the rare crystalline soil was the same as ordinary loess, and people could take it as they wanted, and only the Ding family bought two rare crystalline soil mountains in the whole Dali.

Some courtiers suggested that the imperial court recycle. The emperor was merciful and said that there were only two small hills, and the people bought them were the people's, and there was no reason to grab them back.

Ding Zhao went back and thought about it for a night, and on the second day he found Jiang Shilang of the Ministry of Works, proposed to donate Huangshi Mountain to the imperial court, and also said that his family had built roads and bridges for the convenience of obtaining rare crystalline soil.

He is a small common man, but he is not willing to be the only one in the Great Li Dynasty. Besides, a private foundry could also buy rare crystalline clay, and he just paid for silver.

The emperor and the elder of the pavilion were very satisfied, and felt that Ding Zhao was brave and loyal, and he was still a smart person.

Jiang Shilang also hinted to Ding Zhao that he could build an ironwork manufacturing company on the outskirts of Beijing. At present, only Ding knows how to cast ductile iron in the private iron casting factory, and hopes that the high-quality agricultural tools, kitchenware and some high-quality machinery they manufacture can be provided to the capital and its surroundings.

This is the return given by the imperial court to the Ding family.

Lilac secretly admires that his father is smart and has always seen his position clearly.

First Ding Zhuang heard that Huangshi Mountain was donated, and he was a little distressed, and then he heard that his family could go to the suburbs of Beijing to build a railway bank, and he was very happy.

When the Dong family is ***, the career of the grandchildren will not be bad, and it is not necessary to live in the capital for a long time, so it is just right to build an iron industry line there.

Ding Zhao had already bought 70 acres of land in Shihe County, a western suburb of the capital, more than 60 miles away, and was preparing to build a railway industry and commerce bank there.

Ding Zhao said with a smile, "What Xiangxiang said, you have to do it in one step, and Daddy bought so much land at once. Shihe County is close to Sanjin Province, where there are many black gold and iron ores."

Lilac rejoices.

When the clay is controlled, we will find a way to make steel.

In this era, electricity had not yet been invented, and the only way to make steel was to use the frying process.

It is to smelt the pig iron first, then heat and melt the pig iron to the liquid state, use a blower to blow the liquid metal, and stir the metal at the same time, so that the oxygen in the air and the carbon in the liquid pig iron will react chemically to produce carbon dioxide, so as to achieve the purpose of decarburization.

When the carbon content in molten iron is less than about two percent, iron becomes steel.

The strength, toughness and other mechanical properties of steel are better than those of ductile iron, and the service life of steel knives, steel swords and gun barrels made of steel will be doubled.

Although this process can mass-produce steel in large quantities and does not require rare earths, it is very expensive and cumbersome, and can only be used in the most high-end manufacturing.

Private factories are not allowed to produce weapons, but can produce small quantities of fine kitchen utensils and farm tools, as well as some fine machinery and tools used by craftsmen.

In the future, this factory will be called "Baoqing Iron and Steel Manufacturing Company", which makes both iron and steel, referred to as "Baosteel".

The products are classified by quality and cost from low to high, ordinary cast iron, cast iron treated by annealing process, ductile iron, steel.

Generally, iron is made of ordinary cast iron, annealed cast iron is used for the slightly higher end, ductile iron is used for the high-end iron, and steel is used for the highest-end iron.

However, steelmaking is much more complex than ductile iron and annealing, and it also requires the manufacture of blowers and mixing equipment, and it is not enough to "dream" and find the right opportunity in the future.

Moreover, Lilac only knows the theory of frying steel, and it still requires the craftsman to repeat the experiment, just like experimenting with ductile iron.

First of all, the "Shihe Baoqing Iron Manufacturing Company" was opened and the modern management concept was implemented.

Lilac said, "The construction of the factory must also be in place, not the same as 'Baotie'. It should be based on the changed process and process...... Well, it's manufacturing order to build a factory."

The "factory" she said, Ding Zhuang and his son heard it as a "field room".

Ding Zhao smiled, "I think so too. After looking at the large-scale weapon bureau and the staff bureau, I felt that the method that Xiangxiang had mentioned before was better. I thought of a number of ways to improve the process of separating the whole process of casting and striking iron. For example, sand mold making is a special molding workshop, and iron is made in a furnace

The chemical room, as well as the heating workshop, the forging workshop, and the special cleaning personnel......

Based on the memories of her previous life, Lilac put forward some suggestions for improvement.

After dinner, the three directors of the future "Baosteel" went to the East Wing to continue to discuss the construction of the plant. We deliberated until dark, and then continued after dinner.

Ding Zhao drew the layout plan, and Ding Xiang asked him to vacate a space next to the iron-making room, saying that he would keep it for the time being.

This is used for steelmaking, and special blast furnaces, blowers and other equipment should be built.

Today's meeting not only determined the plant construction plan, but also preliminarily formed the future process flow and process plan of "Baotie".

Ding Xiang suggested that Ding Zhao record these plans to form an official document, and then produce according to this document in the future, and then gradually improve it in the actual production process.

Ding Zhao didn't know at this time how much repercussions the dozen or so pieces of paper in his hand would cause in the future, and even changed the handicraft industry and business model of the entire Dali Dynasty.

After next year, Ding Zhao will take a few people to Shihe County to do some preliminary work.

Ding Zhuang looked at Lilac and smiled.

The prosperity of this family is brought about by the fragrance of incense.

Knowing that Ding Zhi was still alive, he was even more glad about the decision to split up in the first place.

The Iron and Steel Bank should pay attention to the Dalian Imperial Court, and the bigger it is, the more cautious it must be, and there can be no slightest transgression and sloppiness. This is Zhaozi's room, and it has nothing to do with that rebel.

He will die and be his house.

Ding Zhao and Ding Zhuang still had something to discuss, and Ding Xiang returned to the house.

Ding Xiang was very excited, but he didn't expect the prototype of "Baosteel" to be formed so quickly, and the Ding family became the first steel family in Dali to be unstoppable.

However, the political struggle in the capital has become more and more intense.

She didn't know what else Zhu Qianqian would help the court, but she knew that there must be, and the momentum was not small.

Zhu has a lot of potential, and having money is also one thing. Now Zhu Zhan and Qin Qian have gone to the capital again, although their positions are not big, but their role is huge.

The Dong family has this family member in the battle, and they will definitely be able to turn over.

That Master Xun was completely taken into the ditch by the cunning old demon Gu woman. Poor grandma Ruyi, how did she marry such a disgusting man.

I didn't know what Gu's surname was before, Lilac loved to call her "Old Demon Woman Xun", and she will be called "Old Demon Woman Gu" in the future.

She can't represent the Xun family.

Princess Dongyang is also a mallet, helping the enemy raise a daughter, and also helping the enemy to seize the country. When Gao Feng became the emperor and changed the dynasty, the first thing to destroy was the Dali royal family, and the second thing to destroy was Dong Ruyi's descendants, and she couldn't run away from both sides of Dongyang.

and that Xun Qiandai, who is in his thirties, still has such a big playfulness.

Fortunately, there is a Xun Qianli in the Xun family, and he will unswervingly implement the old man's instructions.

As for the fake Xunxiang staying in Kunning Palace half the time, she enjoyed the blessings she didn't deserve in the front, and she had to pay it back later......
