In December, the people of the Transportation Department finally began to transport back the first batch of iron ore, and Ji Yun also returned with the people of the Transportation Department, full of anticipation. Pen, fun, pavilion www. biquge。 info has both expectations for his own future and expectations for what the headland will look like, and listening to others is always better than what he has seen.

The school on the island also rested for a few days near the end of the year, and the eight books had been completed, and an exam was conducted in a simple way, and most of the results were good.

The most difficult tangential spelling and multiplication tables are also done well, and the children of these various cities who studied on the headland island have brought more or less Xia Cheng accents, and they can recognize more words and read more words, and they don't need to use arithmetic chips to calculate simple multiplication and division.

During the rare vacation, these people were not idle, but wandered between various workshops, and Chen Jian did not prohibit it.

The communal baths and dining rooms make these people have a very good relationship with the people of Xia Cheng, and they will answer whatever they ask, but everything that answers is unrepeatable in their city.

Everything on the headland looked so good, and there was a lot of beauty they hadn't seen before.

Due to the exothermic effect of Onozawa's lakes, winter on the headland island is not too cold and the water does not freeze. The large amount of coal used in the workshops caused a lot of smoke and dust in the vicinity of the town, and the air was humid, and there was a thick fog every morning, which was very beautiful, which was rare in other towns.

On the eighth day of the twelfth month, these people learned a new habit of Xia Cheng, a bowl of very sweet porridge to drink in the morning. Corn, wheat kernels, peas, dates, soybeans, chestnuts...... The taste of the eight foods blended together is strange, as if the taste of the summer and autumn sun has been soaked into this bowl of porridge.

It is said that this is a good reason to pray or thank you for the good weather of the past year.

On the third day after drinking Laba porridge, the children had an extra wooden tablet in their hands, which contained a letter written by a person named Ji Yun to Chen Jian, about finding the most labor-saving way to transport ore.

At night, the person named Ji Yun said his thoughts in front of everyone with a little shyness, roughly that he was restless when he thought that Yucheng was being built, and he must find a way to transport more ore and the like, and he would never be slack off because he was thrown into the mine. By the way, I did a self-review, reviewing the mistakes I made a long time ago.

On his chest hung a brass badge, very beautiful, engraved with the appearance of a smoking smelting furnace, it is said that in Xia Cheng only great merit can obtain such a brass badge, and there are different things engraved on it, there are ears of wheat, spears, and so on.

However, the smelting furnace on the brass badge on his chest is smoking, but in reality, there are still some days before the smoke is emitted, and a large amount of ore has been transported back and is being crushed, and it is said that a group of people who can crush ore can be crushed before they can start work.

On the eighteenth day of the lunar month, the smelting furnace was inspected for the last time before it was opened, and after confirming that there was no problem, the workshop workers piled up the ore charcoal in the smelting furnace layer by layer, and the students of the school were also called around to watch.

The linen cloth dyed with ochre was red and wound around the smelting furnace, and two large cloth flowers were pierced.

One hundred and ten bark clay cannons were lit together, and after thinking about it, Jian Chen shouted loudly: "Open the furnace!" ”

People who have already rehearsed it several times will tear up the red cloths, which will be distributed to a few people selected by lottery as a benefit. Several people who drew the lot were responsible for lighting the fire and pulling out the wooden wedges from the waterwheel.

The wooden water wheels began to move, and the rotating connecting rod drove the handle of the bellows, making a loud hula and hula sound, and a flame began to burn at the ignition port.

The clay fans are lined up, and the first batch of iron is used to make the fans. The workshop workers were prepared with clay cauldrons tied to long hard clay sticks to scoop the molten iron into the fan, and each of them had been contacted several times with melted wax oil, at least not accidentally falling on his feet.

Each clay crucible is unique, Chen Jian used the drainage method to roughly calculate the volume of the previous wooden mold, and the size of the crucible in the hands of each workshop worker who is responsible for casting is also different, which is exactly one percent more than the standard volume.

The weather was not very cold, especially near the smelting furnace, and it was uncomfortably hot, and the students of the school went to see it with relish, and they all wondered if this could really make this thing called iron. They all imagined that their cities would be able to do such things.

They had all heard of these things but had never seen them, especially the nearby waterwheels and the connecting rods on the waterwheels, and it was said that after they had finished two years, there would be a simple wooden waterwheel model for them to learn, but it was still far away.

The wait was long, and Jian Chen had been standing near the smelting furnace, constantly passing through the observation holes to either let people fill the material or let people light a fire in the preheating room. This is the top priority of Yucheng, and everything has to be pushed to the back.

The students in those schools gradually walked away because of the cold, they thought that this was a very grand scene, and it would be as shocking as thunder, but after watching it for a long time, they found that it was like a boring spring rain, a numb and cumbersome reincarnation.

After many hours, Jian Chen's hands began to tremble, and the eyes of those who were still watching from the sidelines widened.

Two workshopmen came to the tap with long sticks, and stabbed the blockage with grass ash and mud, and the red molten iron flowed out with excellent fluidity, red as boiling blood.

The lime added to the ore in advance is used as a co-solvent for the slag, so that the fluidity of the slag is very good, and the temperature is enough, so the iron slag is a perfect separation.

Obviously, this is white pig iron, otherwise at the current furnace temperature, if wrought iron or steel is produced, there will be no such good fluidity, because they can only be semi-melted at this temperature. Although Chen Jian has already used preheating blowers and high-power blowers of this era, it can only be like this without coke.

The prepared casters scooped out molten iron, poured it into various strange clay molds, cooled and formed them, broke the clay molds, and put the first batch of iron in the annealing furnace that had been heated up.

The rest of the pig iron is transported to the iron furnace, where it is already heated, and the heat is reflected with the help of the arch structure of the kiln body, and the temperature at which the pig iron melts should be reached using coal as a dye, where the melted pig iron is stirred after melting.

If the temperature is strong enough to melt the pig iron, it is cast first, and if not, it is condensed into small pieces to be forged in the future.

The air was scorching with molten iron, and the hearts of the people were equally blazing, and when Jian Chen picked up a ploughshare for a sample, and smashed the mud shell outside, a black cast iron ploughshare fell to the ground, making a dangdang sound, and there was a burst of cheers around him with this crisp sound.

Everyone ran over to look at this iron ploughshare, Xia Cheng had iron, but it was not copiable, and could only exist in the sacrificial hall as a sacrifice and ritual vessel. And this ploughshare made the people of Xiacheng understand that in the near future, maybe everyone will have a real sickle, a real fish intestine, and a real hairpin...... This is a promise made to them by Jian Chen a long time ago, and now he finally sees hope.

The first furnace of iron is perfect, beyond Chen Jian's imagination, but it is not beyond the actual situation, it is just white pig iron, but it is perfect white pig iron.

But no matter how perfect the white iron is, it is not practical, and the cheers of the crowd made Chen Jian's heart even more stressed, and during the time of annealing, Chen Jian tried to calm down and write the curriculum of tomorrow's school, but his heart could not calm down.

The iron in the annealing furnace does not speak, and does not see any change, and just lies there in the dark, and no one knows whether the graphite is condensing under the gray shell. (To be continued.) )
