Lin Xu first bowed to his father-in-law as a scholar, and then said seriously: "Dad, I am really sure to solve the problem of these iron ingots, please let me try!"
Zhang Lie still didn't believe it, curled his lips and said disdainfully: "If you can really solve the problem of these iron ingots, then I will kowtow to you and apologize!"
"There's no need to kowtow and apologize. Just help me make something."
Lin Xu smiled lightly and said.
"Don't say make one, you can make ten!"
Zhang Lie slapped his chest loudly!
"Then it's settled!"
Lin Xu nodded and continued: "However, you must do exactly what I say. You cannot question it, let alone operate randomly on your own initiative."
The old blacksmith felt that his uncle was very calm and confident today, which was completely different from usual, especially his confident look, which made the old blacksmith feel more hopeful. He quickly said: "Okay, uncle, you can do whatever you want."
what to do!"
Then, he glared at Zhang Lie again: "Did you hear that? Just do whatever I tell you! If you dare not listen, I will break your legs!"
"I heard... Let's see what tricks he can come up with!"
Although he said this, Zhang Lie also felt a sense of hope in his heart.
He did not resist the persuasion of the caravan and bought the problematic steel ingots on his own initiative for the sake of cheapness. As a result, his whole family was cheated and he felt extremely guilty!
If Lin Xu can help him solve this problem, then he is really willing to kowtow to Lin Xu!
"Brother, now please go to the foot of the mountain to pick up some stones. I want the kind of gray stone that is common at the foot of the mountain."
Lin Xu said to Zhang Lie.
"What are you doing picking up rocks?"
Zhang Lie asked in confusion.
As a result, before he finished speaking, his butt was kicked by his father: "Go if you are told, why are you talking so much nonsense!"
Ruolan had been listening to their conversation and had no chance to interrupt. At this time, she walked up to Lin Xu and asked nervously in a low voice: "Guanren, are you...really okay?"
Lin Xu said very firmly: "Don't worry."
In fact, the way to solve the thermal brittleness of iron blocks is very simple. You only need to use a desulfurizer to remove a large amount of sulfur from the iron blocks, or increase the manganese content in the iron blocks. Manganese and sulfur will give priority to forming a high melting point.
The manganese sulfide makes it have certain plasticity at high temperatures, thereby avoiding thermal brittleness.
However, in this era, he didn't know where to buy manganese powder. As for the desulfurizer, although there was no place to buy it, it was simple and he could just make it himself.
The most common desulfurizer is lime powder, which can be obtained by calcining limestone.
At the foot of the mountain outside the village, there are limestones everywhere, and you can’t go wrong just picking them up.
Lin Xu asked Zhang Lie to go to the foot of the mountain to collect stones, while he himself worked with the old blacksmith at home to improve the boiler.
The boiler in the old blacksmith's house was too primitive. It was not the giant shaft furnace that would be commonly used in the future. It was a steamed bun-shaped round furnace about one person tall with an opening on top. It was made of soil and stones. There were several utility poles hung beside the furnace.
A sheepskin bag to blow the wind.
Such a boiler, even if it uses coal as fuel, can only heat to a maximum temperature of 1000°C.
Due to limited conditions and not enough time to build a new shaft furnace, Lin Xu could only try his best to transform it on the basis of this round furnace.
According to his estimation, after modification, this round furnace should be able to heat to 1200°C.
Of course, for the old blacksmith, there is no difference between 1000℃ and 1200℃, so he didn't explain much.
The old blacksmith watched Lin Xu tinkering in the blacksmith shop. Although he was full of doubts, he didn't say anything.
Anyway, the situation is already like this. If the problem of these iron ingots cannot be solved, by the end of the month, their family will definitely not be able to pay taxes, and their family will be ruined by then!
Let’s treat a dead horse as a living horse doctor!
At this moment, he just hoped that his uncle would not lie to him.
In the blacksmith shop, Lin Xu was busy working in an orderly manner. His whole body was covered with black ash, as if he had come out of a coal kiln.
Ruolan and the others saw it and were shocked in their hearts!
Usually, Lin Xu prides himself on being a scholar, often saying things like "a gentleman is far away from the kitchen". He has never even been in a kitchen, let alone a blacksmith shop!
But now, Lin Xu not only got into the blacksmith shop, but also modified the boiler by himself, and he did it in a very orderly manner, not like he was messing around. He didn't care if his face was covered with black ash, he just wiped it with his hand and continued working.
went!
It’s like a different person!
"Ruolan, has my uncle been stimulated by something?"
Outside the blacksmith shop, the old blacksmith asked his daughter in a low voice.
"this......"
Ruolan was embarrassed to talk about Lin Xu's hanging, so she thought about it and said, "He couldn't see clearly when he was walking yesterday and bumped his head against the wall. He was unconscious for a while. When he woke up, he seemed to be a different person.
When we were eating last night, he gave me the bowl of thick wheat porridge, and he only drank a bowl of thin soup. After the meal, he had to wash the dishes..."
"He himself only drinks a bowl of watery soup This chapter has been completed!
