Ruolan walked into the yard and called out timidly.
"Ruolan! Why are you here!"
Zhang Lie was very happy to see his sister, but when he saw Lin Xu walking behind his sister, he immediately lost his temper!
"What are you doing here again? Eat and drink?"
"elder brother......"
Ruolan quickly spoke up and interrupted him, fearing that her elder brother's words would be too unpleasant and irritate Lin Xu.
"Uncle, what do you want to do here today?"
Although the old blacksmith also hated this good-for-nothing son-in-law, for the sake of his daughter, he still restrained himself and asked expressionlessly.
"Dad...I have something to tell you. Can I go to the house and tell you?"
Ruolan knew that Lin Xu had a good reputation and she could never say anything about borrowing money in front of him.
"Well, come in..."
The old blacksmith looked at them with complicated eyes and walked towards the main room.
Ruolan quickly followed.
Zhang Lie glanced at Lin Xu, got into the blacksmith shop, and regarded him as nothing.
...
Inside the hall.
Ruolan carefully said that she wanted to borrow money to pay taxes...
"well!"
The old blacksmith sighed deeply: "Ruolan, if it were normal, dad would definitely lend you the money! However, some time ago, your brother was greedy for cheap and bought a batch of defective iron ingots.
All the money was spent. As a result, these iron ingots accidentally broke when they were being forged while being red-hot, and they could not be formed at all!"
"This batch of iron ingots is considered useless!"
"To tell you the truth, our family can't afford to pay taxes now..."
After hearing what her father said, Ruolan was shocked!
"Is this so possible? Dad, can we return these iron ingots?"
"Refunded? That batch of iron ingots was sold by a caravan traveling from village to village. Now no one knows where it has gone. How can I return it?"
"Then...what should we do?"
"well!"
The old blacksmith didn't know what to do, so he could only sigh deeply!
...
At the same time, in the blacksmith shop.
Lin Xu followed Zhang Lie and walked in. When he saw the basket of iron ingots placed at the door, he picked up one and started looking at it.
"Who asked you to take it? Put it down!"
Zhang Lie was getting angry about the iron ingot. When he saw Lin Xu dared to touch the iron ingot, he immediately burst into rage!
"Brother, is there something wrong with this batch of iron ingots?"
Lin Xu said with an unchanged expression.
"Ouch, you idiot who only knows how to study, you dare to say that there is something wrong with my iron ingot? I warn you again, put it down! Otherwise, be careful, I will beat you all over the floor!"
As Zhang Lie spoke, he walked towards Lin Xu with his fists clenched.
However, Lin Xu's expression remained unchanged and he said calmly: "If I guess correctly, this kind of iron ingot is very easy to break when forged and cannot be formed at all!"
Zhang Lie was immediately stunned!
After coming here for a while, he was very surprised and said: "How did you know? Oh! I understand! You brat, have you listened to other people's gossip?"
It is not a secret that he bought a batch of defective iron ingots. Someone who ordered kitchen knives at his house already knew about it.
In such a small mountain village, entertainment activities are scarce, and when they are not working, the villagers' favorite thing to do is to get together and chat.
The old blacksmith's family bought a batch of problematic iron ingots, which are the biggest ingots in their village these days!
If one person knows, it is basically equivalent to the whole village knowing.
Although Liushan Village and Linshan Village are adjacent to each other, because there is a river between the two villages, they fight over water sources almost every year when irrigating farmland. Therefore, the relationship between the two villages is very poor and there is almost no contact.
Just like Ruolan, she can't go back to her parents' home more than once a year.
In addition, Zhang Lie bought this pile of scrap metal just a few days ago, so this matter has not yet reached Linshan Village.
Lin Xu smiled slightly and did not explain.
When he entered the village just now, he did hear some villagers talking about this matter. Now he took the iron ingot and looked at it, and he immediately understood what the problem was.
In fact, the impurity content of these iron ingots is too high, and the most important thing is that the sulfur content is too high!
Sulfur and iron can form a eutectic with a low melting point. When iron is heated to a certain temperature for hot pressure processing, the eutectic will melt, causing the iron block to crack along the grain boundaries during processing. This phenomenon is called thermal brittleness.
.
Not only does he know what the problem is, he also knows how to solve it.
For him, a doctor of science and engineering in the 21st century, solving such a problem is not too simple!
"Brother, if I help you solve the problem of iron ingots easily breaking during forging, can you help me make something?"
Lin Xu smiled softly and asked This chapter has been completed!
