It was quiet in the study. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

After a while, Xiao Ming drew the drawings, and at this time, there was a sudden sound of footsteps outside the study.

"Your Highness, the old slave is back."

Hearing this voice, Xiao Ming brought a smile on the corner of his mouth, the person who came was none other than Qian Dafu.

This time, Xiao Ming suddenly remembered that the converter steelmaking method was not a whim, and the most important willingness was that Qian Dafu found a magnesite mine in the country, and this ore was the material needed for alkaline furnace lining.

In 1856, the Englishman Besmarck invented the bottom-blowing acid converter steelmaking method, which was the beginning of modern steelmaking, which produced a large amount of cheap steel for Europe and further promoted the industrial revolution in Europe.

However, because this method could not remove sulfur and phosphorus, its development was limited, and in 1879 the Thomas Bottom Blowing Alkaline Converter method was introduced in Europe, which used a converter with an alkaline lining to process high-phosphorus pig iron, further improving the quality of steel.

Because of the lessons of the past, Xiao Ming transitioned from acidic lining to alkaline lining, he did not introduce the converter steelmaking method before, that was because of the limitation of materials, and now that he has found magnesite, the material of the lining will not be a problem.

"Come in." Xiao Ming said.

At this time, the door of the study was pushed open, and Qian Dafu walked in, with a smile on his face, he reached out and took a stone from his arms and said to Xiao Ming: "Your Highness, this is the magnesite mine." ”

Xiao Ming nodded, the ore in Qian Dafu's hand was square, the surface was very smooth, and it was somewhat similar to the crystals of table salt, but Xiao Ming recognized it at a glance that this was magnesite.

"You can't be wrong, this is magnesite." Xiao Ming grinned, and he said, "Now that your prospecting team is getting more and more sophisticated, the harvest in Laizhou during this period is good." ”

Qian Dafu's face was now a little dark, and he smiled and showed a mouthful of white teeth, and he said: "Your Highness, this is also a perfect place, but this Laizhou is really a treasure, not only this Lingmei mine, but also a lot of gold and silver mines, waiting to be mined." ”

"This gold mine and silver mine will not be moved for the time being, this magnesite will be moved, at least some must be collected and used, now the world is in chaos, this is a silver can not buy things, bartering is the right way." Xiao Ming said with a deep groan.

As Qian Dafu said, this Laizhou is indeed a treasure land, not only the first gold reserves in the country, but also the second in the country, the discovery of magnesite is also accidentally discovered when looking for gold and silver mines.

"Yes, Your Highness, the old slave will arrange this matter after he returns." Qian Dafu said.

In the past three years, Qian Dafu, who has gone from an old housekeeper to an ore master, has endured a lot of hardships, and it is precisely because of his hardships and hard work that Xiao Ming has survived the most difficult time at the beginning.

And during this period of time, the prospecting team has become more and more mature, and after thinking about it, he decided not to let Qian Dafu go to the mine in person, after all, Qian Dafu is now in his fifties.

After a deep sigh, he said: "Dafu, when you come back this time, you don't have to run around with the prospecting team anymore, this king has established a mineral department in Qingzhou, and from now on you will be in charge of the mineral department and manage the mines in the country." ”

"Your Highness, is there something wrong with the old slave?" Qian Dafu looked sincerely frightened.

Shaking his head with a wry smile, Xiao Ming said: "Where do you want to go, it's just that you are old now, and there is no one around the mother concubine who can talk when she comes back from Chang'an this time, you have served the mother concubine for more than ten years, and you can accompany the mother concubine to relieve boredom." ”

At the mention of Concubine Zhen, Qian Dafu sighed, "This Chang'an rebellion is really pitiful, in this case, the old slave will hand over the matter of prospecting to his nephew, now that he has learned in Bowen College, he should also let him go out to experience and experience." ”

Xiao Ming nodded, Xiao Ming saw Qian Dafu's nephew when he inspected the mine last time, and this time Qian Dafu mentioned him and agreed to it.

The master and servant said something more, Xiao Ming took Qian Dafu to the backyard, during this time Qian Dafu has been running around, but he has not seen Concubine Zhen.

"!"

Seeing Concubine Zhen, Qian Dafu trotted over, and suddenly knelt down in front of Concubine Zhen, and his eyes were sour.

Since escaping death, there are only two most important people left in Qian Dafu's life, one is Concubine Zhen and the other is his nephew.

has served Concubine Zhen for more than ten years, and Concubine Zhen is both the master and the relative to Qian Dafu.

Concubine Zhen was laughing with Fei Yue'er, and suddenly a black person knelt down in front of her and leaned back in surprise, until she could tell that this was Qian Dafu.

She first glanced at Xiao Ming, "Ming'er, the mother concubine asked Qian Dafu to come to Qingzhou to serve you, how can you let him go out to do such hard work as prospecting." ”

When she arrived in Qingzhou, Concubine Zhen asked Xiao Ming about Qian Dafu's whereabouts, and she knew where Qian Dafu had gone.

Xiao Ming wanted to explain, but Qian Dafu grabbed the conversation, and he said: "Niangniang, Your Highness trusts the old slave because of this, and he is not at ease when this mining matter is handed over to others." ”

Concubine Zhen sighed, "You are also this temper, you have always been a good person, it's good to come back this time, when are you going to go back?" ”

"His Royal Highness said that let the old slave stay in Qingzhou, and he doesn't have to go out in the future." Qian Dafu said.

Concubine Zhen nodded, glanced at Xiao Ming and said: "Well, this is about the same, you will accompany me to talk in the future, relieve boredom, I have been in Qingzhou for a while, I still haven't been out of the palace, you will accompany me to walk around Qingzhou City another day." ”

"Niangniang, you can leave this to the old slave." Qian Dafu said happily.

Xiao Ming breathed a sigh of relief when she saw this, Concubine Zhen had been staying in the palace during this time, and now she was willing to prove that she had finally gradually untied her heart.

After chatting with Concubine Zhen for a few more words, Xiao Ming took the drawings and went to the steel workshop, and Qian Dafu came back to confirm that the magnesite was real, and then he could let go of the converter steelmaking production line.

Once converter steelmaking is on the agenda, this means that a large amount of cheap steel is possible, but the only fly in the ointment is the oxygen blowing technology in this converter steelmaking.

In fact, due to technical limitations, air was blown instead of oxygen in the initial converter steelmaking, and the real oxygen blowing technology only appeared in 1952.

He has also studied industrial oxygen production, and the current Qingzhou is simply unable to overcome this technology, and it is a high-tech to condense the air to more than 100 degrees and then separate.

So in view of this, he decided to use the traditional method of blowing air, after all, even during the First World War, this method was still not backward and enough for him to use.
