"I think we can try to use artificial graphite as a refractory!"

"Do you mean by the method of calcination of petroleum coke and asphalt?"

"Yes! We must have a large amount of coal chemical tailings, can't we use them to make graphite? ”

"That's right! It just so happens that graphite electrodes are also available. ”

"If you want me to see it, it is still reliable to use coal for pressure calcination, and reliable quality is the most important!"

"Calcined coal is best anthracite, oh dear! Do we have one now? ”

"There will definitely be in the future, now ......"

"Well, so let's use petroleum coke and asphalt, which are all by-products of coal and coke chemical industry anyway, so it's a lot, right?"

"Uh-huh, it's just that the purity is almost there! Does it not affect the quality of the subsequent process? ”……

"Ahem!"

"Hey, hey, hey!"

Seeing that the group of people engaged in metallurgy, chemical industry, and electric power were discussing it enthusiastically here, there were people around me who were interfering.

"Everyone! Everybody! Let's talk about these specific technical details, but for now, I'll move on! ”

So Mr. Zhao smiled at the group of people at the next table, and waited patiently for everyone to be quiet, and then began to continue the introduction:

"The synthesis rate of nitric acid produced by the arc method is less than five percent, so the output is very low, especially in the early stage, nitric acid may become our bottleneck, but at least it is better than nothing, anyway, sooner or later we have to go out, when the time comes, a large number of saltpeter will be imported, not only the production is much cheaper, but the output can also go up."

As soon as Zhao Xihe said this, someone in the audience at another table said loudly:

"Mr. Zhao, I heard that India produces high-quality saltpeter! And the locals don't know that when the time comes, we will be able to get the saltpeter back."

"People are not Indians, they have been civilized for thousands of years, I don't believe that you can use any method to deceive, can you exchange glass beads for those saltpeter?"

"Yes, everyone was so civilized back then that they were embarrassed to be civilized again, otherwise it would be the turn of Europeans to do something?!"

"I said, are you addicted to crooked buildings!"

At last, someone in the audience interfered with dissatisfaction.

"Alright, alright! Continue to listen to Mr. Zhao's chemistry class! Be quiet, y'all! ”

"Teacher Zhao, hurry up, there should be a lot of content, right?"

Sun Lao also asked Zhao Xihe on behalf of everyone.

"Well, there is also a set of small rubber plastic refining and processing lines, including vulcanization equipment, this is too professional, I won't say more, the output is not high, and the estimated quality is average, but it's still better than nothing, right? That's right! If the textile sector can give us specialized industrial fabrics, we may be able to make tires or something in the near future. ”

As soon as everyone heard Mr. Zhao talk about tires, they immediately came to the spirit and discussed:

"Tires! That's good."

"It is estimated that ordinary transportation is unaffordable, it is too expensive!"

"It will be cheaper in the future......"

"It doesn't matter if he's expensive or not, we give priority to protecting our own anyway."

"In this way, as long as the internal combustion engine is developed, then we will be able to have a car in our lifetime!"

"It doesn't have to be the internal combustion engine, I've heard that there were coal-burning cars in the past, and if you wear tires, it's quite windy to run on the road!"

A group of high school students are starting to make up their brains again.

"Yes! This is not bad, can you play racing? ”

"Your family just plays steam engine racing! Have you ever heard of a Formula 2 steam engine car? ”

"Haha, that sounds a little weird!"

"Hey! I advise you not to despise this! There are really steam car competitions or something in the world! It's your own loneliness! ”

"Okay, everyone, be quiet, listen to Mr. Zhao!"

Sun Lao finally couldn't help but pat the table and shouted, which made the restaurant a little less noisy.

“…… In addition, about soda ash and caustic soda, we only need to have the key mineral limestone, fortunately there are a lot of them on this island, well, I won't say too much about the technical details of the specialty, in short, the two alkalis in the three acids and two alkalis are easier for us to prepare than the three acids, and the complete set of causticizing equipment is also ready-made.

In addition, thanks to seawater chemicals, we can even use the future technology that Anna has given us to make a simple ion exchange layer membrane that can produce many chemicals including caustic soda in large quantities with high efficiency, and because of this, our combined alkali production process may soon become a reality.

Therefore, I would like to emphasize once again that from the current aid project, the reason why our chemical industry can be carried out smoothly in the future is because Anna has given us advanced seawater chemical technology. Therefore, the seawater chemical project should be our priority project.

Because of this project, we have a very surprising advantage in terms of catalysts, enrichment agents and molecular filters.

Therefore, I can confidently assure all of you here that with the right raw materials, the chemical industry will reach the level of the beginning and middle of the last century in the near future!

Well, it seems that the seawater chemical gold finger that Anna gave us is a little against the sky, and we also feel a little embarrassed to open it, but fortunately, this is not writing a time-traveling novel, otherwise it will definitely be sprayed by a reasonable party......

But it doesn't matter, the reasonable party always thinks that the fiction must be beyond reality, but in fact, they don't realize that this is their own thinking mistake - in fact, reality is more fantastical than fiction! OK！ That's probably all for the chemical industry, so please ask Mr. Sun to continue to preside over the meeting. ”

After Zhao Xihe finished speaking, he looked at Sun Lao, who immediately looked around the venue, raised his finger and pointed at Quan Zhenhai, Huali, An Hengtong, Ren Ke, and said:

"Now it's metallurgy's turn, and that's our main aid project."

After the four of them bowed their heads and whispered a few words, the eldest Hua Li stood up, he spread a few pieces of paper on the table, looked down, and then spoke on behalf of the metallurgical group:

"Metallurgical aid equipment is mainly divided into ferrous metallurgy such as iron smelting, steelmaking, steel rolling and non-ferrous metallurgy such as copper smelting.

After Hua Li finished speaking, he looked up at everyone, and found that everyone was looking at him quietly, and after glancing down at the information on the desktop, he said:

"First of all, I want to introduce this miniature iron-smelting blast furnace, it is estimated that Anna is taking into account everyone's physical strength and initial production conditions, the iron-smelting blast furnace he got for us is actually not high, and the base is only 3.5 meters, which is indeed worthy of the word 'miniature'.

The blast furnace is a circulating water-cooled type, which has many advantages, of course, because it is a miniature furnace, so the maximum size of the filler is only 300 kilograms, that is, if it is mixed with coke, it can produce about ...... iron at a time It's only about 350 to 400 kilograms.

Obviously, the advantage is obvious: because the charge is less in one fill, the labor intensity is not large, and it is easy to control the temperature of the furnace and the proportion of coke.

If it is continuous production, counting the filler and preparation time, with our current rookie Xiaobai's actual hands-on ability, about three or four hours to produce molten iron, of course, this is my preliminary estimate, the actual situation is not yet known. ”

When Holley said this, he was immediately drowned out by everyone's discussions.

"Actually, I'm most worried about our physical strength, can we really do these jobs?"

"Didn't you say miniature?"

"No matter how tiny it is, it's ironmaking!"

"In my experience, there is no easy job when it comes to burning a stove or something!"

"Only three or four hundred kilograms of molten iron are produced at a time, which seems to be a special fuel, right?"

"Obviously, Anna didn't take into account the input-output ratio, and of course she also took care of our physical strength."

"It's okay, we have labor in the future, we only need to enlarge the size of the furnace according to the proportion, won't the output go up?"

"That pyrite can actually be co-produced with the chemical group."

"Hey! In fact, what I'm most worried about is letting us carry the ore! ”

"You're talking about pyrite? Don't worry, you'll definitely have to carry it for a while. ”

About the steel industry, has always been a major topic of concern to everyone, before everyone has not been less discussed, now that the real discussion is here, there will naturally be all kinds of discussions.
