Chapter 991

In 991, three iron in one

the two brothers in the East were surprised.

Dongfang Junhua reached out and took the drawing. "You mean to wrap the soft iron with two layers of hard iron, and combine the three irons for a sword?"

Gu Qianxue nodded, "yes! In fact, it is more appropriate to name the two pieces of hard iron with "steel". The pig iron with a lot of impurities is soft and tough, which is called iron. What martial arts pursue is a combination of hardness and softness. Can't we forge swords? "

Oriental Junhua was shocked and murmured, "hard and soft, right! Once upon a time, the biggest problem we encountered was that the steel was easy to break. Why not add a ductile core to it

After getting along with Gu Qianxue for a long time, Jun'an is used to Gu Qianxue's amazing ideas from time to time, and is less shocked. "Can three pieces of iron melt together?"

"It is possible in principle, but whether it can be integrated depends on the technology and equipment." Heavy snow.

Different from Jun'an's query, Dongfang Junhua was eager to try, "it doesn't matter. I'll try it and know if it can be integrated." Then he would change his clothes and light a fire.

"Slow, there's more." Snow trail.

Dongfang Junhua's eyes at Gu Qianxue can't be described with amazement. If he used to see a beautiful woman in his eyes, now there are fairies in his eyes, "Miss Zhao heard."

Gu Qianxue stretched out his hand, and Chuyan handed over a big cloth bag.

"Is this?" Dongfang Junhua is puzzled.

"It's manganese." As he spoke, Gu Qianxue untied the cloth bag.

Dongfang Junhua knows about manganese mines. There are many mines in Mingjian villa, which are useless and toxic. The villa stipulates that absenteeism should be avoided as far as possible, and manganese ore attached to iron ore will be excavated to fill the abandoned mines. "Miss Zhao means adding manganese ore to iron? In fact, for thousands of years, the ancestors of Shanzhuang have been trying to improve the casting formula, and manganese ore has also tried, but... "

"It's because of the wrong dosage," Qian Xue interrupted him, "adding one manganese ore for every 100 iron ores. Have you tried such a dose?"

Dongfang Junhua and Jun'an are surprised that there is such a big gap between 100 iron ore and one manganese ore. what is the difference between adding and not adding?

Gu Qianxue saw what they thought and said, "although the casting technology of Mingjian villa is excellent, you have never thought that the excellent casting technology is not only unique to Mingjian villa? Why is the iron produced here better than other places? Don't you think that the gap lies in the material? The biggest feature of Mingjian villa is iron and manganese ore. although you try your best to remove manganese ore, it has been fused in the formation of minerals for thousands of years. Because of the fusion of iron and manganese, the iron of Mingjian villa is different from that of other places, and the weapons cast are also different from those cast in other places. "

Dongfang Junhua nodded. "The ancestors of Dongfang family have thought about the material of Miss Zhao, but no one can be sure. Maybe As Miss Zhao said, the problem is manganese ore. According to Miss Zhao, because of the existence of Trace Manganese ore, the iron in the villa is different from that in other places; and because impurities are smashed out in the casting process, but manganese is also lost, so we should add manganese ore now, right? "

"That's right." Snow must say.

In fact, many modern special steels are widely used and of high quality. A piece of scrap steel is much better than the refined steel of this era. However, Gu Qianxue is really helpless in steelmaking because he remembers some knowledge he learned in geography class in high school, but he is still vague and vague.

And the real special steel needs trace elements not only manganese ore? There are tin ore, nickel mine and so on. Gu Qianxue doesn't want to embarrass himself any more. A manganese mine is OK.

Jun'an doesn't know how to cast a sword. Although he subconsciously wants to refute it, he doesn't speak to the fourth brother, so he shut his mouth obediently.

Dongfang Junhua thought for a moment, then nodded, "let's have a try." He said to Jun'an, "five brothers, we cast a knife at the same time. You use iron ore and mine add manganese."

"Good." Without saying a word, Jun'an changed his clothes and made a fire.

Because it involves a professional, Oriental Junhua eyes less infatuation, more calm, "a hundred iron, a manganese, is that right, Miss Zhao."

"Yes." Gu Qianxue doesn't know how much to add. Let's add 1%.

"Well, let's try first. Miss Zhao and miss Chuyan had better stay away from each other, or the smoke will choke you." Oriental Jun Hua gentle way.

"Yes." Gu Qianxue did not say a word, pulling the first smoke to run.

Gu Qianxue didn't stop until the other corner of the yard was far away from the two brothers in the East.

Early smoke light looked at the direction of the corner of the hospital, "miss in the heart, in guilt." It's not an interrogative sentence, it's an affirmative sentence.

Qian Xue took a timid look, then sighed and nodded, "yes, I have no way. Jun'an asked me to hide my identity. I can't tell Dongfang Junhua that I'm married, right? After the marriage, the married married woman threw aside her husband and ran out to take part in the sword casting meeting. The influence was not very good. " I scratched my hair impatiently.

Chu Yan sighed, "otherwise, let Jun'an head give Dongfang Junhua that the young lady has a sweetheart and is even more a fiance, how?"Qian Xue suddenly realized, "OK! very nice! That's it! Chuiyan, you are so smart

First smoke bitter smile, smart? How clever is she? If you are really smart, why can't you think about your own business and make a decision?

"They are forging iron. What do we do?" Gu Qianxue began to be bored.

In this yard, it's not convenient to practice martial arts, and there are no books to read. There is a set of chess on the side of the yard. But Gu Qianxue is better off playing iron than playing chess. Besides, Chu Yan doesn't look like a chess player.

The first smoke was silent and did not know what he was thinking.

Suddenly, Qianxue had an idea, "how about cooking?"

"Cooking?" First smoke a Leng.

"Yes, I haven't made Matcha thousand layer cake for a long time. I'm afraid I haven't eaten it yet. We're also free when we're free. There's a kitchen. Let's make cakes."

First smoke mouth corner, but want to Gu Qianxue said Jun'an did not taste, the bottom of the heart is also ready to move, "maids listen to miss."

So they started to make cakes.

In a flash, half a day passed, it was afternoon.

Because of the urgency of time, Jun'an and Dongfang Junhua did not stop to have lunch, and made the knife with which he broke his promise at one breath.

At the same time, Gu Qianxue and Chuyan's Matcha thousand layer cake is also fresh, warm is the soft glutinous delicious time.

When they came to the casting table with the cake, they heard a crisp sound, followed by Dongfang Junhua's surprised voice, "amazing! What a surprise! Miss Zhao is such a God that she can invent such a formula
