Chapter 555: Lining material

The study is very quiet.
In a short while, Xiao Ming drew the drawings seven or seven eighty-eight, and then suddenly there was a footstep outside the study.
"His Royal Highness, the old slave is back."
Hearing this voice, Xiao Ming put a smile on his mouth, and the person who came was not someone else, but a rich man.
This time, Xiao Ming suddenly remembered that the converter steelmaking method was not a whim. The most important wish was that Qian Dafu found a magnesite ore in Fengji, and this ore was the material needed for alkaline furnace lining.
In 1856, the British Besmer invented the bottom-blowing acid converter steelmaking method. This method was the beginning of modern steelmaking. It produced a large amount of cheap steel for Europe and further promoted the European industrial revolution.
However, because this method cannot remove sulfur and phosphorus, its development is limited. In 1879, Thomas bottom-blowing alkaline converter steelmaking method appeared in Europe. This method uses a converter with an alkaline lining to process high-phosphorus pig iron. Further improve the quality of steel.
Because of the lessons learned, Xiao Ming transitioned from acidic furnace lining to alkaline furnace lining. He didn't introduce the converter steelmaking method before. That was because of material limitations. Now that he found magnesite ore, the material of the furnace 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 quietly. 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 cube in Qian Dafu's hand was very smooth, with some crystals similar to salt, but Xiao Ming recognized it as magnesite at a glance.
"It can't be wrong, this is magnesite." Xiao Ming grinned, and he said: "Now your prospecting team is getting more and more sophisticated. You have had a good harvest in Laizhou during this time."
Qian Dafu’s face is now a little dark, with a smile showing his white teeth. He said: "His Royal Highness, this is also a chance, but Laizhou is really a treasure, not only the Lingmei mine, but also many gold and silver mines. , Just waiting for mining."
"This gold mine and silver mine will not move for the time being. This magnesite mine must be moved. At least some must be collected and used. Now the world is in chaos. This is because there is silver and you can't buy things. Bartering for goods is the right way." Xiao Ming Groaned.
Just as Qian Dafu said, this Laizhou is indeed a treasure. Not only is the gold mine the first in the country, but the magnesite reserves are also the second in the country. The discovery of this magnesite is also an accident when looking for gold and silver mines. found.
"Yes, Your Highness, the old slave will arrange this after returning." Qian Dafu said.
In the past three years, Qian Dafu has suffered a lot from being an old housekeeper to an ore proficient, and it is precisely because of his hard work that Xiao Ming passed the most difficult time in the beginning.
During this period of time, the prospecting team has also become more mature. After thinking about it, he decided not to let Qian Dafu go to mine in person. After all, Qian Dafu is now in his 50s.
After pondering for a while, he said: "Dafu, when you come back this time, you should not run around with the prospecting team. This king has established the Minerals Department in Qingzhou. From now on, you will be in charge of the Minerals Department and manage the domestic mines. The field will do."
"His Royal Highness, is there something wrong with the old slave?" Qian Dafu looked frightened.
Shaking his head with a wry smile, Xiao Ming said, "Where did you think of going, but you are now older, and there is no one who can talk to your mother and concubine when she comes back from Chang'an this time. In the new year, you can accompany your mother and concubine to relieve boredom."
Speaking of Concubine Zhen, Qian Dafu sighed, "This time the Chang'an chaos is really pitiful, so the old slave should leave the mine hunting to his nephew. Now he has learned something in Bowen College. , We should also let him go out and practice."
Xiao Ming nodded. The last time he visited the mine, Xiao Ming saw Qian Dafu's nephew. This time Qian Dafu mentioned that he agreed to this matter.
The master and servant said something again. Xiao Ming took Qian Dafu to the backyard. Qian Dafu has been on the go during this time, but he has not seen Concubine Zhen.
"Manny!"
Seeing Concubine Zhen, Qian Dafu ran over and suddenly knelt down in front of Concubine Zhen, his eyes were sour and he started to cry.
Since escaping from the dead, only two people remain the most important in Qian Dafu's life, one is Zhenfei and the other is his nephew.
For more than ten years, she served by the concubine Zhen, who is the master and relatives of Qian Dafu.
Concubine Zhenzhen was joking with Fei Yue'er, when suddenly a dark person knelt down in front of him and leaned back in shock, until she realized that this was the rich and the rich.
She first gave Xiao Ming a blank look, "Ming'er, the mother and concubine let Qian Dafu come to Qingzhou to serve you, how can you let him go out to do the hard work of mining?"
When she arrived in Qingzhou, Concubine Zhen asked Xiao Ming about the trace of Qian Dafu, and she knew where Qian Dafu had gone. At this time, seeing Qian Dafu's appearance was a little bitter for a while.
Xiao Ming wanted to explain, but he was snatched by Qian Dafu. He said, "Niang Niang, your highness is because you trust the old slave. He doesn't worry about leaving the mine hunting to others."
Concubine Zhen sighed, "You are the same temper. You have always been a good person. It's fine to come back this time. When are you going to go back?"
"His Royal Highness said to let the old slave stay in Qingzhou, so 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 almost the same. You will accompany me to talk and relieve my boredom. I have been in Qingzhou for a while. I still haven't been out of the palace. You will accompany me another day. Let me go around in and out of Qingzhou City~EbookFREE.me~ Niang Niang, then you leave it to the old slave." Qian Dafu said happily.
Xiao Ming breathed a sigh of relief when she saw this. During this time, Concubine Zhen had been staying in the palace, and now she was willing to prove that she was finally relieved of her happiness.
After chatting with Concubine Zhen for a few more words, Xiao Ming took the drawing and went to the iron and steel workshop. Qian Dafu came back to confirm that the magnesite mine was real, and he could then set up a converter steelmaking production line.
Once the converter steelmaking is on the agenda, it means that a large amount of cheap steel becomes possible, but the only flaw is the oxygen blowing technology in the converter steelmaking.
In fact, because of technological limitations, air was blown instead of oxygen in the initial converter steelmaking. The real oxygen blowing technology only appeared in 1952.
He has also studied industrial oxygen production. Qingzhou cannot overcome this technology at all. It is a high technology to condense the air to more than 100 degrees before separating it.
Therefore, in view of this, he decided to adopt the traditional method of blowing air. After all, this method was not backward even during the First World War, and it was enough for him to use.
