Chapter 506: Steelmaking on the Right Track, the Sudden Appearance of an Adventure Group

Soon, the little fox ran over.

"Sir, what are your orders?" Goglis smiled.

"Your mental state is much better than before." Field patted the little fox on the head.

Goglis shyly hugged her tail: "Well, maybe it's because she has found her own value."

"Very good, it just so happens that I need to build a steel-making production line."

Field took her to the industrial area of ​​the Night Territory.

Today's industrial areas are no longer just a bunch of shabby workshops. There are two small factories for making wooden furniture. In addition, there are well-planned wood, soap, flour, paper and blacksmith shops, making it a complex industrial park.

The most eye-catching ones are the eight iron-making blast furnaces in the east, which are like chimneys and emit billowing smoke. What is peculiar is that the blast furnaces were built continuously rather than widely separated. The molten pig iron produced in one blast furnace is directly poured into another blast furnace to refine mature molten iron.

The craftsmen smelted the iron step by step, while the slaves blew the blast furnace, creating waves of heat.

"Do you know what the key to steelmaking is?"

"Um..."

Goglis was about to answer something like the craftsman's proficiency or the temperature, but when she saw Field's "test you" expression, she immediately fell into deep thought.

"Perhaps it's charcoal?" Goglis considered it. "Since the construction of the blast furnace, our iron output has increased many times and we have made a lot of farm tools. But ~ when making steel swords, craftsmen will mix wrought iron with charcoal. Beat until they come together."

"I once asked craftsmen why they put iron and charcoal, two unrelated things, together to beat. They said they didn't know, it was just the experience of their predecessors. I think this is likely to be the key to the problem. "

Field cast a surprised look.

If I had not systematically studied steel, I would have never thought that the key to steel lies in its carbon content.

"I remember that the territory only made a few steel swords. They were used by me to check the technical level of the territory. I didn't expect you to remember them."

"Yes, the key to forging steel lies in the carbon content. The carbon content of pig iron is higher than 2%, while wrought iron is lower than 0.05%, and steel is somewhere in between. Therefore, as long as you have molten iron and carbon, If you keep tossing, you will definitely get steel!”

"But the steel obtained through beating is a luxury product. We can't make a few steel swords in a year, so it is of no use to the territory."

"Carbon content..." Gao Gelis kept thinking about this obscure word.

"If I said that everything in the world is made of tiny particles, would you believe it?"

"I believe it." Without hesitation, Gao Gelis nodded heavily, "I believe everything you say."

Patting the little fox on the head, Field promised: "As long as I am in the territory from now on, come to my study at night and I will give you a good tutoring lesson."

Not caring about the ambiguity of these words, Goglis nodded solemnly again.

"Having said that, if you want to make steel, you must first get coke. Coal is not suitable for steelmaking. Coke is easy to make. Coal can be heated to a high temperature of about 1,000 degrees without oxygen."

Gao Gelis was a little dizzy: "Aba, Aba, what is 1000 degrees?"

You can't test it with your hands.

"Our current iron-making furnace can reach about 1,400 degrees. Cooling it down is much easier than raising it. The craftsmen and materials here are at your disposal. Just try it boldly. We have time."

There is no science that does not require experimentation, and you cannot do everything yourself.

Field took out two drawings: "These are two sets of crucible steelmaking and converter blowing technologies. Both of them can be used with blast furnace ironmaking to form supporting production lines. You should learn them first as a knowledge reserve."

Gao Gelis took over the two sets of drawings and her eyes widened instantly. They were densely packed with notes, pictures and texts.

Although I can’t quite understand it, it looks very powerful.

"Sir, which set do I need to build?"

The key to crucible steelmaking technology, which uses molten iron, is the graphite crucible, which allows the molten iron to absorb the carbon in the graphite and increase the carbon content.

When blowing steel in a converter, molten pig iron is used. The key is to blow in oxygen while stirring the molten iron to form carbon dioxide and reduce the carbon content.

"I have sent people to search for and purchase graphite mines. You need to help me build a hydraulic blowing device. Because the process of blowing oxygen takes more than ten hours and requires water power."

If slaves are allowed to come, productivity will still not be liberated.

"Got it, make coke and build a hydraulic blast!" Goglis shouted in a coquettish voice, "I promise to complete the task."

Field nodded with satisfaction: "Let's take action now and strive to increase steel production soaring."

Once we have steel, we can wholesale manufacture plate armor, cement, steam engines, and various lathe tools. These are the keys to lighting up technology.

On the other side, everyone from the Adventurer's Guild, wearing all kinds of cool equipment, came to the border of Maple Leaf Territory.

The fortress door slowly opened, and the soldiers inside the fortress looked at the adventurers with sympathetic eyes, as if they were looking at dead people.

"Get out quickly, we are closing the door." Hearing the roar of corpses in the distance, the soldier turned pale with fear.

The purple-haired adventurer said in a strange tone: "What are you afraid of, little brother~"

"You know nothing!" the soldier cursed and immediately chose to close the city gate.

"Wow~ Is this the Northern Province? It's different from any place I've ever explored before." A swordsman looked around in shock, "It's just like hell."

"I don't know which one is more dangerous here or the super-large underground maze in Kesai Province."

"Of course it's an underground maze." A red-haired female boxer said with a grin, "After all, there are living people coming in and out of the Night Territory."

"Baron Field? I heard that he made a deal with the devil and became its lackey. The Imperial Guard who came to investigate died in the Maple Leaf Territory."

All the adventurers were talking about it.

"Yeah, otherwise Maple Leaf Man... huh huh." Adventurer Edgar was about to say something when a priest covered his mouth.

"Don't talk about the nobles. This matter cannot be discussed on the table."

"Okay, okay, since I accepted the noble's mission, I will definitely complete it properly."

Edgar blew his bangs irritably: "After all, I want to be a brave man."

"Brother Edgar, why do our hunter adventure group come here?" The little Lolita wearing a pink skirt and holding a purple wooden staff asked timidly while holding the staff.

Edgar leaned down and said coolly to the new members: "Of course it's to get rewarded. There are more than a dozen powerful adventure groups exploring the Northern Province together."

"The first is to detect the movements of the corpse tide and hunt down a powerful third-level corpse BOSS."

"Second, it's a private mission. Baron Simon has privately entrusted us to investigate Baron Field's stronghold."

"This is an S-level mission!"
