52 oxygen converter steel smelting

Meili doesn't like Tie Zijun's arrogant attitude, as if he is the only one in the world who has a noble character.

But this does not prevent the two from becoming friends, just like Tiezijun doesn't like him to be flirting with her - of course, that's the past, now...

Being powerless.

It's impossible!

The two quickly arrived at the most core area inside the steel plant.

"This is the steel we produce. Look at it, is it very different from before?" Tie Zijun picked up an iron ingot and gave it to Meili.

Meili picked up the iron ingot and looked left and right.

In this regard, he is also an expert. Although he is not an expert like Tiezijun, he still knows a little bit.

After watching for a while, he raised his head: "Old Tie, have you made a major breakthrough in your craft? This kind of steel is completely different from the previous ones. Although I can't tell where it is different, I dare to be 100% sure, it's really different."

"Yes, this is steel produced according to a brand new process." Tie Zijun said with a smile.

After a pause, he continued to explain: "We lack scrap steel, and the iron ore we mined from Hengling has low phosphorus content and low calorific value. In this way, we will not only not be able to use the Mass steelmaking method, but also eliminate the economics of the production of the open furnace, and can only use converter steelmaking! I originally planned to try the process I invented here, but Dashuai gave me a more advanced process..."

"Wait!" Meili hurriedly called Tie Zijun: "What did you say just now? You said that the Grandmaster gave you a more advanced craft!"

"Yes!" Tie Zijun nodded.

"Master can still make steel?"

Mei Zi's eyes widened and she was stunned.

Tiezijun turned his head and looked at Meili, saying, "So I will tell you just now that the wisdom of the handsome man is not something you can imagine."

After a pause, Tie Zijun said: "I got Dashuai's process, we worked overtime and immediately verified it.

After planning, we soon began the experiment of steelmaking in industrial pure oxygen top blowing converter.

You see, we first conducted it in which 2-ton container. After achieving satisfactory results, we switched to a 15-ton container to produce more than 10,000 tons of crude steel.

This kind of equipment is essentially roughly the same as a 30-ton equipment.

After the above tests, we affirmed that Dashuai's steelmaking method not only smoothly in steelmaking, but also obtained ideal chemical composition and could reach the required casting temperature, which could also meet other necessary production conditions well."

"After preliminary verification, we believe that the oxygen top blowing converter steelmaking is fully in line with the overall route of Mao Dashuai's large, fast, good, and saving. The investment in the construction of an oxygen converter steelmaking plant is about 50% compared with the same size of the open furnace steelmaking plant, and the production cost per ton of steel is equivalent to 80% of the open furnace steelmaking steel. Obviously, this means that it is fast and saves. So much? According to general calculations, the annual output of a 35-ton oxygen top blowing converter is about 225-ton open furnaces. Moreover, after the converter steelmaking uses industrial pure oxygen blowing, the quality of the steel has been greatly improved, at least the same as the open furnace, and it also meets the good requirements."

Tiezijun started talking in a daze.

Meili was confused when she heard this. These things were too professional and he couldn't quite understand them.

Tiezijun wanted to talk again, Meili interrupted, "Okay, stop talking. I don't understand if you talk. Just tell me, how about this kind of steel?"

"Very good!" Tie Zijun said affirmatively.

"very good?"

"Yes, although we cannot give more data for the time being, after a brief test, this steel has made breakthrough progress in all aspects in elongation, cold brittleness, chemical composition, cold pull, tensile strength, yield strength, etc., and will definitely meet all your needs!"

"Are you sure?" Merry was still a little suspicious.

"Do you think I look like a lie?" Tie Zijun stared at Meili with her eyes: "I am a person who will follow the Grandmaster all my life and has always had high requirements for myself, so if this kind of steel was not really too excellent, I wouldn't have taken it out to show you!"

When Meili heard this, she nodded, and the last bit of doubt in her heart was eliminated.

Tie Zijun said: "The Grand Marshal attached great importance to the anti-demonic action, so he asked me to make the best steel for you, so when you look at me, my eyes are red, I haven't been sleeping for several days. I just want to work overtime to get some of the best steel for you."

"Thank you for your hard work!" Meili wanted to pat Tie Zijun's shoulder, but raised her hand and realized that she could not reach Tie Zijun's shoulder. When the two of them hugged her just now, the other party bent down.

"It's okay, we are all doing things for the Grand Marshal. As long as we can do the best things that the Grand Marshal ordered!"

"Then when will I get these steels!"

"The day after tomorrow!" Tie Zijun said: "This is the first batch of steel that was released. I am not very satisfied with it in some aspects and I will return it to the furnace. In three days, I will give you the best steel."

"Okay, then I'll wait for your good news!" said Merry.

Tiezijun nodded.

at this time.

City Lord's Mansion.

Luo and Meizi are also busy.

The two of them found a lot of information and read it one by one.

These materials are all about anti-demonics. Some are from Chuzhou's own collection of books, others are transported from Longcheng, and of course, some are purchased from the imperial capital.

This is another preparation Cao Yu made for the anti-demonic action.

Cao Yu attached great importance to the anti-demon operation, and made every effort to make all preparations, material, weapons and equipment, and soldiers' combat capabilities, of course, also including relevant understanding of the monsters, as well as understanding and summary of previous anti-demon operation.

Meizi and Luo were searching for relevant information, while Cao Yu was searching for what they found.

As he looked at it, he was suddenly stunned: "Have you found a problem?"

Um?

Meizi and Luo turned their heads together and looked at Cao Yu strangely.

"The destructive ability of invading the monster is gradually weakening?"

"Huh?" Luo was stunned, obviously caught off guard by Cao Yu's question.

Meizi had this knowledge, so she nodded and said, "Yes, Grandmaster, the destructive ability of invading monsters is indeed gradually weakening. If I remember well, it should have started fifty years ago."

Cao Yu was stunned for a moment, and then continued to look at the information in his hand.

According to books, the first invasion of Warcraft should have occurred more than two hundred years ago.

At the beginning, people in this world used magic to resist invading monsters.

The monsters at that time were very terrifying, huge in size and amazing destructive power. Of course, at that time, the magician's magic was also very powerful. If a fire magic was used, a ground as big as a football field could instantly burn to ashes.

However, afterwards, the magician's magic became weaker and weaker. Fire magic gradually changed from the size of a football field to the size of a basketball court, and then the size of a pool table. Now, the most powerful magician, the magic flame can only be as big as a washbasin.

However, the invading monster did not change much until fifty years ago.

In recent years, monsters have become weaker and weaker. If you use a better rifle, if you can hit the heart of the monster with one shot, you can basically kill a monster with one shot.

After reading the information, Cao Yu's brows became tighter and tighter.

Something is wrong!

He had a vague feeling that something seemed wrong.

In addition to the destructive power of the invading monsters becoming weaker and weaker, another problem arises, that is, the coordinates of the invading point were basically unchanged fifty years ago, but starting from fifty years ago, the invading coordinate points will change every three or five years.

Of course, according to previous experience, it is not yet time for change this year.

But this made Cao Yu's heart suddenly feel. The coordinate points of this year's Warcraft Invasion will not change, right?

What if the Warcraft doesn't enter from the point I entered last year?

After looking for a while, Cao Yu suddenly raised his head and asked Mei Zi and Luo: "You were all magicians before, so based on your magician's experience, what magic is the most afraid of by monsters?"

"Fire Magic!" Meili and Luo said in unison.

"Fire?" Cao Yu was stunned, then nodded: "In this case, it's time to get the flamethrower out!"

On Earth, the flamethrower was first unveiled in the trench war of World War 1. The first flamethrower was invented by the German R. Filled in 1901, but it was not widely used in World War 2.

There seems to be no flamethrower in this world. Of course, maybe it already exists, but Cao Yu has not seen the relevant information yet.

Flamethrowers are not complicated and have much easier design than rifles. The only problem is that flamethrowers are relatively bulky and require high physical fitness.
