The elder brother grabbed Yan Bing's head and gave him a scolding.
Yan Bing rubbed his ears and smiled throughout the whole process, showing his humbly accepting it.
It wasn't until Yan Bing promised that in the future, any purchase of more than ten taels would have to seek the opinion of the senior brother first, so as to avoid a situation like today where he wasted money on his banknotes, the senior brother finally took a breath and stopped talking.
.
Yan Bing obediently took the teapot and filled the two senior brothers with tea, then ran off and started working.
Yan Bing discovered that when it came to working, his magical power was fully utilized.
First is the ore powder.
Yan Bing took off the hammer from the wall and hammered it down on the iron ore. Most of the ore was broken into slag. When he hammered it down again, the slag instantly turned into powder...
Just hit it with hammer after hammer, and soon there was a small pile of iron ore powder on the ground.
Yan Bing nodded with satisfaction.
Start washing coal blocks.
The washed coal blocks are then classified according to coking properties and size.
Then I fished out the yellow mud from the big vat of the iron shop, filled the iron billet with yellow mud with the mud, shaped it, and patted it flat until the iron billet was evenly coated with a thick layer of yellow mud.
Then he nodded with satisfaction.
Next is coking.
First, measure the size of the crucible, then find a porcelain plate, and make some gestures to find that it is just enough to cover the crucible.
Then Yan Bing put the coal that he had just sorted into the crucible, covered it with a plate, and finally sealed the gap between the plate and the crucible with yellow mud to ensure that no air could slip in.
These are the best preparations.
Just have to turn on the furnace.
What she didn't expect was that it was the least technical thing like "making a fire" that stumped her as a master's student...
She squatted on the ground and lit it for a long time, but she couldn't light it.
I didn’t know how to use the blower, so I struggled for a long time and still couldn’t light a fire.
In the end, senior brother couldn't sit still...
He wanted to help her..., but he had just lost his temper and couldn't bear to help her, so he kicked Lu Liang, who was napping next to him.
Lu Liang was suddenly awakened and thought something had happened. He quickly looked at his senior brother and asked, "What's wrong?"
The eldest brother didn't answer and just nuzzled at Yan Bing.
Lu Liang turned around and saw Yan Bing lying on the ground struggling with the stove.
He smiled understandingly, went over and patted Yan Bing's shoulder and said, "I'll do it."
Yan Bing nodded with a look of shame.
Sure enough, the stoves of the ancients had to be made "compatible" by the ancients.
Three times five times two, the fire in the stove is lit.
Yan Bing took advantage of the situation and put the crucible up.
I heard the senior brother behind me say sarcastically: "I've never seen you like this. To make a sword, you don't burn iron, you burn coal first. Are you going to use coal to make a sword for our master?"
Yan Bingxin said, explain it to him... But she couldn't explain it clearly, so she just smiled and squatted aside and stopped talking.
After about a few cups of tea, I felt that the time was almost up, so I took the crucible off the stove.
Then he moved away from the fire source, turned to the two senior brothers and said: "When I open the lid later, I hope that the two senior brothers will hold their breath and count to twenty before inhaling. There is poisonous gas in here. I am afraid of hurting the two senior brothers...
.”
After receiving Lu Liang's affirmative reply and Feng Chen's nod, Yan Bing held the crucible in one hand and the tongs in the other, lifted the plate on top... and then immediately threw away the tongs and covered his mouth and nose with his hands.
….
In fact, the poisonous gas she is talking about is the large amount of carbon monoxide produced when coal is coked, commonly known as "coal gas".
Originally, this kind of gas was a better steel-making material than coke. Unfortunately, with the current level of technology, he couldn't collect it at all, let alone store the hard-won carbon monoxide... He could only watch it being evaporated to the
In the atmosphere.
After about ten seconds, Yan Bing fanned the air with his sleeves several times, then tried to breathe a little, poured the dried coal on the ground, scooped water from the water tank with a ladle, and poured it on the coal hard.
splash.
Keep pouring it for about a minute or two, then smash it with a hammer, press it into briquettes, put the briquettes near the stove with tongs, and let them air dry.
Then she made the second and third furnaces, until a small pile of coke was accumulated, and she nodded with satisfaction.
He stood up and stretched.
However, he heard snoring coming from behind. When Yan Bing turned around, it turned out that his senior brother and his fifteenth senior brother had fallen asleep side by side.
The snoring sounds were louder than the other, one high-pitched and the other low-pitched, with a vague tendency to evolve into a duet...
Yan Bing smiled and shook his head.
The trouble was caused by oneself, so let them sleep...
While the coke was drying, Yan Bing took off his blacksmith's leather apron and went to the street to buy some.
I don’t know how long it took, but the senior brother leaned over and woke up suddenly.
I originally wanted to continue sleeping, but suddenly I felt something was wrong. I rubbed my eyes and looked around carefully.
Lu Liang suddenly stood up with a slap on the chair.
"What happened!? The furnace exploded!?" Lu Liang was obviously sleepy and looked around to see where the loud noise came from.
The eldest brother kicked him and shouted: "Still sleeping! The baby bump is gone!"
"What's the baby bump?" Lu Liang rubbed his eyes but didn't react.
"Junior sister! Junior sister is missing!" the senior brother yelled.
When Lu Liang heard that his junior sister was missing, he completely woke up and hurriedly said: "Separately look for her!"
Just as the two of them walked out of the blacksmith shop and came to the entrance of the alley, they saw a little boy coming back from a distance carrying a big baggage.
The two of them took a closer look and saw that this was none other than the junior sister. They hurriedly approached her.
Lu Liang took the baggage Yan Bing carried behind him, while Feng Chen fanned Yan Bing with his sleeves.
The two of them tried to trick her like they were coaxing children.
After chatting for a while, I found out that the junior sister had gone to buy tools. Seeing that they were sleeping soundly, it was hard to wake them up.
The two of them breathed a sigh of relief.
It was not easy to find such a "treasure lump". If some thieves from the Luomen Cult kidnapped the junior sister while they were sleeping, Master would have to skin them both with his own hands.
After breaking into a cold sweat, the two began to discuss the division of labor.
One of the two people is sleeping, and the other must be awake and protect the junior sister at all times.
Lu Liang put down the baggage on his back and took a look, only to realize that there were some old things inside.
Wooden boards, wooden strips, saws, half a piece of cowhide, needlework, hemp rope and jade materials.
Yan Bing first made a handheld blower using cowhide and wooden boards, as well as wooden strips, needlework, and hemp rope.
Open and close your hands, agitate the cowhide, inhale, blow, simple piston principle.
But such a simple gadget can instantly increase the temperature of coal and coke by hundreds of degrees.
Thus, completely liquid molten iron is smelted, and during the dissolution process, iron ore powder is continuously added and stirred, so that the iron ore powder rich in carbon elements becomes a carburizing agent, which accelerates the integration of carbon into the wrought iron.
This is the earliest steel manufacturing process, the fried steel method.
But coke and air blast are also necessary conditions for completing this technique.
Otherwise, if the temperature is too low, wrought iron and steel will not be able to completely liquefy.
When the carbon content of wrought iron reaches a certain value, this epoch-making product, "steel", is born.
After several repeated experiments, Yan Bing finally mastered the optimal amount of iron ore powder to add.
After pouring the molten steel into the mold, the sword embryo was repeatedly smelted, beaten, smelted, and beaten. After nearly a hundred repetitions, until all impurities in the sword embryo were completely hammered out, the steel was made...
Already…….
When the first hundred-refined steel sword was formed, it was already early the next morning...
Yan Bing was so tired that he almost lost all strength...
He fell to the ground and fell asleep.
He didn't even know how he was sent back to the inn by his two senior brothers.
