Chapter 216
In the ironworks, Paul, Burns, Conrad and others looked at a red-hot sword embryo on the workbench in silence.
Blacksmith Herman picked up a hammer and hit the sword embryo hard.
After the sound of metal shattering, the sword embryo turned into fragments.
The hearts of Paul and Conrad were also broken.
Herman said helplessly: "Lord, that's it. The forged sword embryo cannot be forged at all, and it will break with a little force."
"Why? Why is this?"< br>
Paul couldn't believe it. How could the iron he worked so hard to refine become scrap metal?
“Herman, could it be that your skills are not up to par?”
“My Lord Earl, I have been practicing for more than ten years, and most of the swords in the Lord’s Mansion are mine. Typed out.”
What was the wrong step? Paul was a little anxious. He paced back and forth in the room, thinking about every process in ironmaking.
At this time Conrad said: "Your Majesty, is it because there are too many impurities in the pig iron?"
"Impurities?"
"Yes. Yes, after all, we use your newly invented 'coke' to make iron. Maybe... there is something in it that is different from the charcoal we used before, and then it was mixed into the molten iron?"
"Oh? ! Conrad, you are such a genius, you hit the point right away.”
After Conrad said this, Paul remembered a piece of information he had read before. It said that pig iron made with coke is not suitable for turning into mature iron, because the coke will bring impurities to the iron, making the wrought iron brittle. Cracking occurred during forging.
At the same time, he also thought of the solution to this problem-the stirring method.
To use this method, you must first build a remelting furnace (reverberatory furnace), and then use the remelting furnace to melt pig iron. This furnace can directly use raw coal as fuel, and the iron and raw coal used as fuel will not directly contact, so impurities in the coal do not have harmful effects on the metal.
After the pig iron is remelted in the reverberatory furnace, a stirrer is used to continuously rotate on the hearth to stir the molten iron, and through the decarburization effect of the circulating air in the furnace, it becomes malleable wrought iron. until. In this process, the wrought iron impurities produced are greatly reduced because contact between the metal and the fuel is avoided.
Paul expressed his thoughts. Although they didn’t understand what decarbonization meant, everyone felt that the Earl’s method was worth a try.
So the craftsmen in the ironworks built a remelting furnace as quickly as possible according to Paul's shooting, melted and stirred the previous scrap iron, and after several days of experiments and process improvements, they finally made Hermann. Wrought iron approved by old blacksmiths.
Paul was also relieved. If he couldn't pass this level, all his previous investment would be in vain.
Under his instructions, the 51st District Arsenal began to try to use iron to cast cannons, because iron is cheaper than copper. Once the iron cannon is successfully developed, it will greatly reduce the cost of the artillery and increase the number of Alda troops. Number of artillery pieces.
......
As time goes by, the old year is finally coming to an end, and people in Huxin Town begin to prepare to celebrate the New Year, but some are happy and some are sad.
The little princess Irene was lying on the window sill, staring blankly at the heavy snow outside the house.
Liya just came home from get off work - she found a job as a teacher at Weiss College. Seeing her like this, she asked in a low voice: "Miss, are you homesick?"
"Missing home? Huh! I don't, this is my home."
Liya sighed, she knew that the little princess was just trying to show off her words.
"Your Highness, how about...we return to Jingyao?" "Back to Jingyao? Liya, do you want me to surrender to my father? No, I, Eileen Rodney, will never do anything Compromise.”
"Then let's send a letter to Jingyao to let them know that we are safe?"
"Send a letter? Do you want them to go to the northwest bay to catch me?"
< br>Liya thought to herself, it seems that Her Royal Highness the Princess's resentment has not gone away, so it's better not to get into trouble with her.
So she went to prepare dinner silently.
Erin looked at the female waitress walking to the kitchen, feeling that her words just now were a bit rude, and she felt a sense of guilt in her heart.
Her heart is very complicated now. On the one hand, she still has unresolved resentment, and she is afraid of being captured by her father and used for political marriage. On the other hand, she really missed her relatives, her sister, her mother, everyone she knew in Jingyao, and even her father who was still resentful, especially during the important days from Advent to New Year. inside.
"Ah...it's really annoying!"
Irene was a little crazy.
While the little princess was worried, what she didn't know was that many eyes were staring at her.
In a house across the street, two figures were talking.
“The inspection is over, there is nothing unusual around!”
“Thank you for your hard work!”
“Alas, the little princess’s troubles have made it difficult for us to even have a good holiday. "
"What are you saying? Protecting the safety of the royal family is our basic duty. Even if the princess is in the royal capital, don't we have to be careful during the festival? "
"That's true, but I still want to do something more exciting, such as working undercover as an undercover rebel to spy on the enemy, instead of taking care of children who have run away from home all day long."
"How about you again? So, I'm going to give you a snitch. We'll do what we're told, don't be picky."
"Okay, okay, I understand. , We have to be more careful in the future. Today I was interrogated by the 'police' here for a long time. Fortunately, I reacted quickly and kept my words straight, so I didn't ask any questions."
"Look. It seems that Count Grayman is paying more and more attention to the security in the territory. This is a good thing. The better the security, the safer the princess will be. There is no problem with our identity. Besides, we are not spying on the lord's family. The secrets of the industry and his affairs in the army are not afraid of shadows.”
“But I am afraid of being caught as a stalker and voyeur.”
"Shut up, hasn't this been discovered yet?"
"Speaking of it, the changes here are really big! I heard from the locals that half a year ago this was a place where rabbits didn't poop."
“Oh, this is all thanks to that young lord. I have also inquired a lot about his deeds.”
“What a magical guy, even the majestic princess of the kingdom is willing to Work under him."
"The things he has created are indeed quite attractive. If I were a scholar, I would also want to get close to him. You went to Weiss College and saw the so-called "publicity". Class'? That microscope, my God, it's amazing! ”
"Oh, stop it. Thinking of those little bugs makes me sick to my stomach."
