Chapter 546

Georgia leads West, on the edge of the Cumberland mountains.

"Turn on the stove!"

With the order of the person in charge, the main body is built by firebrick, and the outer layer is wrapped by steel. There are workers who do a good job of body protection, use the hook to pull open the door of the taphole.

Hoo -

the heat is surging, the iron is splashing, and the orange red hot metal is rushing out. Then it flows through the tundish and slowly injects into the water-cooled crystallizer.

Although the final pig iron ingot has not been fully formed, there are cheers among the onlookers. Everyone's face is covered with a layer of red light, not only because of the reflection of hot metal, but also because of the boiling blood in the body.

"Oh

"Oh, yes!"

"Hahaha, it's really refined. This new blast furnace is really wonderful!"

Olivia, who was also watching the door of the stove, waved her pink fist, turned her head slightly and saw the same excitement in Elvin's eyes.

Just a moment.

A thin middle-aged man in a gray wizard's robe, with one eye replaced by a red artificial eye, trotted to them with a rough surface, dark color, and a 10 kg pig iron ingot.

Hold the ingot in front of Elvin with both hands and bow down to report to him the first time the furnace was started:

"my Lord, the ingot is coming out, and the quality is very good. The first batch of molten iron has been crystallized and weighed. Now it seems that there is no problem that the average daily output of 600 tons can reach the design capacity. "

He took the ingot in his hand, and Ivan broke it with his bare hands. When he saw the section, he nodded with satisfaction:

"Mr. kingslam, it's hard."

Wen Yan said that the thin middle-aged people with artificial eyes bent lower, but they did not dare to take credit at all:

"thanks to the new ironmaking technology brought by adults, our work is not worth mentioning."

Obviously, this is a wizard apprentice of the former "mechanical immortality school", and an apprentice who is not young and has little potential to go further.

Now it's the end of September.

After they were brought back to Georgia and implanted with symbiotic strains by Elvin.

This group of wizard apprentices who return to the orthodox "constructivism" and are all smart people, have completely seen the form, and have been humbly enriched into various new industries in the territory.

And give their own far more than ordinary people's knowledge and ability to bring a qualitative breakthrough for these industries.

These guys have the cruel side of doing taboo experiments, but they also have the pure side of technicians. At least with the help of this group of wizard apprentices, Elvin's industrial planning has blossomed a lot, and the pace of development has rapidly entered the fast lane.

Just like the first newly built blast furnace at present, its effective volume is 200 cubic meters. The average daily output of pig iron is 600 tons, and the annual output reaches an amazing 220000 tons.

If we put it into Elvin's era, this is a proper backward production capacity, and we must sweep it into the garbage heap of history without hesitation. But now, compared with the technology that the Kingdom has just learned to make iron with coke, its significance is epoch-making.

Even if the effective volume is expanded to 400 cubic meters, or even 800 cubic meters, there is no technical difficulty.

For this reason, after carefully screening the iron and steel workers, Elvin also dispatched a large number of loyal "Pipi people" to serve as the factory guards of the iron and steel plant, strictly guarding the secrets here.

This technology is obviously not from the hands of alchemists, but from the city of an ancient god in the spirit world, which is the harvest of Elvin and Olivia in a spiritual exploration.

In the past, when they met the city of ancient gods, they would deliberately avoid it, but now with the myth language and ancient people's code as a reward for maze clearance, they may turn it into valuable knowledge.

Although not to deliberately chase, but also will not deliberately escape.

Among the practical technologies that they two analyzed, this advanced ironmaking blast furnace equipment is just suitable for the current situation in Georgia.

It needs 1.5-2.0 tons of iron ore, 0.4-0.6 tons of coke and 0.2-0.4 tons of flux (limestone) to smelt 1 ton of pig iron with this blast furnace technology, and 2-3 tons of raw materials in total.

In order to ensure the continuity of blast furnace production, there must be sufficient raw material supply, which is the advantage of Cumberland mountains, which is rich in iron ore and coal.

The first generation blast furnace (from start-up to overhaul and shutdown) can be continuously produced for several years to more than ten years, which can be regarded as a huge profit. It is also regarded by Elvin and Olivia as the key to lead the steel industry in Georgia to counter attack.

In the future, with the expansion of industrial scale and the improvement of steel production capacity, Georgia will eventually choose the whole new world or even the whole world.

After encouraging the steel workers here, they left the "steel city" which has just started.

In the blink of an eye, they came to the central part of the territory more than 100 kilometers away through the black chamber, which is also the second stop of their inspection - ceramic town.

It may have the most abundant porcelain clay resources in the world. How to realize the clay is the top priority of their work.When they stepped out of the black chamber and came to this small town with only a few buildings.

Old buck, will and Kenneth, another wizard apprentice who once escaped from the sword of the evil spirit "deer bone God", have been waiting here.

Seeing this mysterious method, they showed them the first batch of finished products after opening the kiln yesterday with a look of awe.

In fact, there are only a dozen items in total, not only small items, but also full of various defects.

When Olivia marveled at this magical "magic" and picked up a dark blue porcelain bowl to play with carefully.

However, Elvin frowned slightly and was not very satisfied:

"since it's the first batch, even the finished product rate of defective products is too low, I'm afraid it's not even half Chengdu?"

In his memory, the qualification rate of ancient porcelain should reach about 10%, not to mention the defective products.

Mr. buck, who has two brushes for firing pottery, is currently the technical director here. He went forward to report carefully:

"my Lord, there are 200 pieces of porcelain embryos in the kiln, and only these 11 pieces can be completely picked out. Most of the others are broken. In my experience, the main problem lies in the control of furnace temperature. "

In Elvin's knowledge system, there is not much reserve for ceramic firing.

I only remember that the firing temperature of pottery is 800-1000 degrees, and that of porcelain is 1300-1400 degrees. Different porcelain clay in different places, the specific firing temperature is also different, to the final sintering.

The craftsmen have been informed of all these secrets that are not passed down in peacock islands in advance, but it will obviously take a long time and a little bit of experiment to reach the final success.

In addition, enamel on porcelain is another difficulty.

Glaze is actually the bright coat on the surface of porcelain.

The main raw materials are clay, quartz and feldspar, which are grinded, modulated, coated on the surface of embryo, then roasted and melted at high temperature, and cooled to form glassy crystals.

The three most basic and simple colors are celadon, white porcelain and black porcelain. Celadon appeared the earliest, with iron content between 1% and 5%. White porcelain is less than 1% and black porcelain is more than 5%.

The first purpose of this experiment was to produce celadon first, and the short-term goal was to produce white porcelain which was popular among the kings and nobles in the old world.

Firing white porcelain is not only the process of removing iron from glaze, but also the basis of all other colors. It is an important milestone in porcelain firing.

After that, we will consider the issue of personalized color. The colorant of blue and white is cobalt. Red comes from iron oxide or copper oxide. Other Evans can't remember clearly.

After thinking about it, he looked at the three people again:

"at present, firewood is the main fuel for porcelain firing, and coal can also be used. The nature of the fuel determines that the furnace temperature is really difficult to control. After that, we will continue to test. Anyway, we have no shortage of raw materials. "

After a pause, he specially named the wizard apprentice:

"Mr. Kenneth, can we try to design a temperature control device with the help of alchemy? You are responsible for submitting a feasible research plan to me.

At least we should be able to produce white porcelain steadily, and then we can start to sell to the market. Gentlemen, I don't need to say much about the value of porcelain. The chance to turn clay into gold is just around the corner. "

"Yes, my Lord!"

With the knowledge support from Elvin, they have already taken a big step ahead of other countries that are also developing porcelain. If they still can't make achievements, it's hard to say.

...

when they returned to the governor's house hand in hand, it was already the afternoon of that day.

The warm golden sun covered the clean and tidy study. Elvin and Olivia leaned on the wide sofa, feeling a little tired.

With the increasing ability of Kaka, they can travel around the governor's house, wizard tower and territory at any time, so as to achieve meticulous control of this 100000 square kilometers of land.

In just half a day, they went to five towns all over Georgia, dealing with all kinds of affairs, and even the physical fitness of the extraordinary was a little tired.

In addition, combined with the knowledge of "construction" inherited by gem witchcraft and alchemists, the short-distance transmission device in the wizard tower has begun to be established.

Later, the members of the school and even the officials of the territory could take advantage of it, indirectly letting Elvin firmly grasp the whole territory.

There is no need to worry about the resources needed.

After the extermination of the "mechanical immortality school" that day, he also raided the spoils.

It is worthy of being the representative of advanced productive forces and a big dog among witches. Less than 20 of the official wizard, just magic bag found five.

Moreover, after the fortress collapsed, although it rushed to the bottom of the river, it was opened and packed as a whole without any waste. In addition, knowledge from the "mechanical immortality school" has equipped the impoverished "activation school" with rocket thrusters.In the aspect of personal cultivation, Elvin has begun to study Volume II "flesh and blood puppets" with angel.

But in addition to the progress of mindfulness, one of the biggest problems for Evan's promotion to the third level is to make pioneering achievements related to the inheritance of the first three volumes of biology.

Ivan's secular invention can be said to carry a lot of cars, but this pioneering achievement of the wizard road needs to be considered.

"Master, viscount, afternoon tea is ready."

Just then, in a decent Maid Dress, Sarah came in with a silver plate. This group of beautiful "night spirit" has been well brought into the role of their maid, and the speed of adaptation is amazing.

"Thank you, Miss Sarah."

Looking at this "night spirit" who is actually 38 years old, but still as young as a girl, Evan's mind suddenly flashed.

"Yes!"
