Chapter 159

Steelmaking is both simple and easy, but also difficult.For today's technology, steelmaking is just a matter of a few buttons, and automation can be completed basically after the input of raw materials.

But even if Wang Ziye got all the equipment in this way, it would be of no use to him.Now he does not lack steel, what he wants to do is to start intermediate metal smelting through steel making.

So what he has to do is start from scratch.

It is not difficult to obtain a small amount of iron ore and coal, he just needs to open the technology tree first in case of emergency.What is really difficult is the blast furnace, or to be more specific, how to react iron ore with coal to reduce iron oxide in iron ore to iron.This requires a temperature that can melt iron, which cannot be achieved by simply burning some firewood.

As for the various other auxiliary materials, they are secondary. All he needs is that the manufactured thing is steel.

In fact, bronze was much simpler to produce.But after the unlocking of primary agriculture, Wang Ziye discovered that only producing one product can unlock the entire technology of the same level, which is only effective for the first time.

The primary agricultural technology that Wang Ziye has unlocked today is mainly the cultivation of some vegetables and food crops, and involves the knowledge of irrigation and fertilization.On top of this, intermediate agricultural technology will involve the cultivation and planting of some economic crops, which further improves land utilization, diversification, and can simply interfere with some characteristics of plants-selective breeding.

But this kind of technology can only be accumulated little by little, and only when it is produced can it be recognized by the system.That's why Wang Ziye wanted to directly unlock the intermediate smelting.As for advanced smelting, I'm really sorry, it can't be done.

The intermediate smelting technology also has its particularity, that is, it is completely developed around this steel.This is similar to primary smelting, except that the core is changed from bronze to steel.

Of course, don't look at the fact that there is only steel in intermediate smelting, but just steel and iron are divided into countless detailed categories.The most basic pig iron, wrought iron and steel have very different properties.What's more complicated is the proportion of carbon. Any increase or decrease will change the properties of steel, as well as the addition of various other elements.

Steel supports the entire intermediate smelting technology, but it is not just the intermediate smelting technology.

Everyone at the conference table was lost in thought, and no good plan was proposed for a while.We all know that ironmaking is done by adding carbon to iron ore and heating it.But that's all they know.

"Why don't we build a blast furnace first?" said Yi Biao, who was in charge of the construction department.

"We don't have iron ore or coal, but we can find substitutes," Wang Hui said.

"But the difficulty now is the temperature. We have no way to reach such a high temperature. And the construction of a blast furnace requires modern machinery, which cannot be recognized by the system. We have to start from scratch." Wang Ziye gently Squeezing the space between his eyebrows, he continued, "Enabling intermediate smelting is a prerequisite for subsequent unlocking of many technologies. Unlocking in advance is very beneficial to our future development."

"This matter can't be rushed. I think it's better to let the whole people participate." Chen Zonghai suggested, "In particular, some of the materials in the materials are engaged in related industries, and some students also major in smelting."

"That's all it can do."

After Wang Ziye finished speaking, this matter was put aside first, and everyone discussed some other matters, and the meeting ended.

Steel smelting, everyone knows its significance.But you can't focus all your energy on it.Soon, several people engaged in related industries and those students majoring in smelting were summoned.They set up a team dedicated to public relations related matters.However, after a few days, there was no progress. Instead, a teacher majoring in history proposed a feasible plan.

The history teacher proposed to follow the example of the ancients and use the method of smelting iron to produce steel.The so-called "block iron smelting" is because it was difficult for ancient people to obtain the high temperature to melt iron, so the prepared iron exists in the form of a spongy solid block, which is soft in texture and contains many impurities. Wrought iron used.

When forging an iron block, people can also put it into charcoal and heat it repeatedly, so that the iron block can absorb the carbon element in the charcoal, reduce sundries, and form rigidity.

This method was quickly approved by Wang Ziye and implemented quickly.But after the first piece of steel was prepared, they encountered new difficulties.

Although this method can produce steel, it is inefficient.If it is still like unlocking the primary technology, it only needs 10 kilograms, which is okay.However, after the emergence of new side missions, the required amount was 10 tons.Only one unit has been changed, but its difficulty is completely different.

To unlock this task with today's method, regardless of external threats, even if less than 5000 people are involved, it will take several months of work.More importantly, this method consumes too much carbon.

Steel is okay, but at worst, some building materials will be smelted into waste products and used as iron ore.But the surrounding area is a poor mining area, and there are no coal mines at all.But now thermal power stations are a rarity.The carbon used before was all cut down green trees and fired.

After a while, it returned to the original point. If the heating problem is not resolved, the progress of steelmaking will not be able to be brought up for a long time.

The issue of steelmaking has not progressed for a while, but the gains in vegetable food are not small.

Although the river water in front of the community is not civilized, the ice surface has been sliced ​​open, and people directly send the ice blocks upstairs to turn them into water to irrigate the plants.

All the high-rise buildings in the Liming Territory have been turned into greenhouses, and some vegetables with a short maturity period are planted in the well-lit area on the south side, as well as crops such as potatoes and sweet potatoes that can be used as staple food and vegetables.

At the same time, after expanding the planting, three new mutant plants appeared, and all of them were cold-resistant, which greatly expanded the room for choice. Wang Ziye believes that it won't be long before the mutant plants can satisfy people's daily needs. demanded.

The space in the center of the room was not idle either, and some grass was planted there.Although the domestication of the territory has not yet achieved much results, it can only provide some egg food, but this still requires the consumption of a lot of forage.

On the back side, where there is almost no sunlight, the shade-loving mushrooms are planted.However, although growing mushrooms had been carried out from the beginning of the territory, problems always occurred.Because the mutation rate of mushrooms is too high.There was even a case where a mutated mushroom devoured all the mushrooms planted together.Fortunately, the monitor faithfully recorded the situation at that time, so that casualties were avoided.
