"Axiom triumphs, axiom triumphs!"

Students marched into a procession, carrying slogans and shouting slogans, with smiles on their faces from the inside out, and the whole school joined into a sea of joy.

Seeing that Cheng Nuo was still standing there, the students hurriedly gave Cheng Nuo a small red flag, and said with a smile in their mouths: "Professor Cheng, we have won, and justice has tried!" This is for you, would you like to join us in the parade? ”

It stands to reason that Cheng Nuo is very happy to be willing to join their team, but thinking of the series of things he may face later, he can't bear to mess up this beautiful moment.

After all, in a sense, this is the first time that the Chinese people have "defeated" the great powers, and they can appear in front of the world as a victorious country as a defeated country once they throw off the hat of a defeated country.

"It's okay, you guys go first, I still have a lot of things in my hand, I'll come to you when I put them away." Cheng Nuo patted the book on his chest, saying that he had a lot of things in his hands, and it was inconvenient for him to participate in their rallies.

Where are students willing to give up? They all expressed their willingness to send things to Cheng Nuo.

He Cheng Nuo has his own ideas, but he really has no intention of participating in this false victory, and this also means that the window for its development of heavy industry is getting smaller and smaller, and the possibility of a comeback of the great powers will be greater and greater, and the time can no longer be delayed.

Several people argued with each other, came and went, and accidentally knocked the book in front of Cheng Nuo's eyes to the ground.

"I'm sorry, Professor Cheng, we didn't mean to, we'll help you clean it up now." The student saw that things had messed up and quickly apologized.

"It's okay, you guys are busy with your own business, it's just these few books, don't stay with me for a long time, delay your business." Cheng Nuo shook his head again and again, and directly squatted down to clean up by himself: "The flow of people is so large, there is a risk of stampede if you stay in place for a long time, so I'll do it myself." ”

Coincidentally, as Wen Yin's last notebook fell to the ground, some newspaper clippings were scattered from it.

Originally, Cheng Nuo would not do the matter of checking people's privacy, and he was unwilling to do it.

But what I never expected was that there was a photo of Cheng Nuo in the newspaper clippings that were called up, and it was written on it - congratulations to Professor Cheng Nuo, a Chinese scholar, and Professor Planck, a German scientist, for successfully conducting academic exchange activities.

Looking further down, there are basically news about Cheng Nuo, big and small, such as mathematical papers, innovative machine factories, chemical industry, etc., some news that even Cheng Nuo himself doesn't know.

Picking up these newspapers, Cheng Nuo was stunned, and secretly had some conjectures in his heart.

In order to test these conjectures, Cheng Nuo branched the students apart, then found a quiet place, opened the notebook, and flipped through it from the beginning.

Sure enough, it was almost full of Cheng Nuo's big and small news, starting with his first paper when he just returned to China and ending with his recent speech back to Peking University.

Whether it is Cheng Nuo's article or not, as long as there is something about Cheng Nuo, the notebook has been collected and cropped.

In the middle, there are some errors in the report or the record is not in place, and the content has been specially expanded, as well as various memos, which are simply not very detailed.

Looking at it, Cheng Nuo didn't know what to say for a while.

No wonder just now, no matter what, the other party refused to hand over this notebook, it turned out that there was a reason for this.

"The sun rises in the east and rains in the west, and the road is sunny but sunny."

The relationship between children and daughters is always short-lived, and after cleaning up the mood here, Cheng Nuo immediately began to devote himself to intense work.

Especially in this month, not only Austria signed an armistice with the Entente.

As for how tragic the war was in the four years of World War I, there is no need to mention this, but when it comes to some industrial aspects, especially heavy industry, Cheng Nuo still fights for it.

Because Germany, as a defeated country, had to surrender heavy artillery, planes, warships, trucks, trains, etc.

As their friendly companions, it is natural to take it to squeeze the last juice.

Especially now that the next world war is over, China already has a modern domestic banking system concentrated in coastal cities and an important light industry base, which can continue to develop in one go.

However, there are good and bad things, and there is also a difference between urgent and non-urgent needs, and after returning to the courtyard, Cheng Nuo pulled everyone to hold a meeting in the courtyard.

"With Germany's military industrial capacity, he has been defeated, does Zhiyuan think that our efforts are in the right direction?" Looking at Cheng Nuo, someone raised this question, which was not only a problem for him, but also a question in the hearts of many people here.

Looking to the left and then to the right, Cheng Nuo held the table with both hands and said slowly: "I believe that it is not only the comrade who has this question, here I will briefly tell you about it, if Germany does not have such a strong industrial strength, then they will be beaten down directly like we did before."

The reason why they will fail is also because the war is not only about military strength, but also about comprehensive national strength. As for how to improve the comprehensive national strength, industry is one of the most important aspects. ”

After speaking, everyone nodded one after another, and began to seriously discuss industrial needs, going around and around, and finally returning to the steel industry.

"Comrade Dean, in the past, the domestic iron-making technology was relatively advanced, the steel-making system was second, and the steel-rolling technology was the least developed, but now ......" Shi Jin stood up and finished the first half of the sentence, looked around and continued: "Now these situations have greatly improved, but only the technology of the mining system is backward.

This backwardness has led to the imbalance in the development of our steel technology, which is not conducive to the long-term development of the steel industry, so I suggest that our next development can be more considered in mining. ”

Cheng Nuo on the stage thought for a while, and finally affirmed: "I have also considered this problem, but in the final analysis, it is still that the labor resources are abundant and the price is low, which makes the mining production link mainly rely on human labor, resulting in backward production technology." ”

Shi Jin nodded, then shook his head and asked, "But why is our ironmaking and steelmaking making making making so fast, we have already achieved a lot of results in this area before we intervene." ”

Cheng Nuo waved his hand to sit down and explained: "In fact, it is very simple, in contrast, because China must continue to increase the import of pig iron to Japan, ironmaking technology is more advanced in terms of ore processing and furnace capacity, of course, this is also relative to other links of domestic steel production."

However, this also reminds me that if you want to develop the steel industry, you must open up the upper and lower industrial chains, especially now that the European war is over, it is difficult to say anything else, but it is certain that steel prices will plummet, and the price may even be lower than the pre-war average. ”

In terms of mining, Daye Iron Mine, which belongs to Hanyeping Company, is the earliest and largest iron ore deposit in China. However, until the fall of the Manchu Qing Dynasty, stope mining mostly used explosives blasting and manual rock excavation to chisel large pieces of ore for transportation.

It wasn't until several years later that they purchased several steam pressure rock drills, using steam power instead of manual drilling, which is still a relatively advanced mining method in China.

Some of the remaining enterprises use a large number of manual operations, many iron ore is mined by locals, and steel mills buy it at a price of less than 10 yuan per ton, and the mining method completely relies on the soil method, basically relying on local cheap labor to mine manually, and there are no mining machines.

"So can we develop some mining equipment to save manpower?" Wu Yulin stood up and offered his proposal.

This is exactly what Cheng Nuo thought, and continued along with the other party's words: "Regarding the steel factory, in fact, I have always emphasized to you that the focus of future development may be in the southwest province, and large factories will also give priority to this place, and Mr. Tesla has been working there since he joined our organization." ”

Tesla, on the right, nodded and confirmed Cheng Nuo's words: "Yes, Comrade Dean is right, I have been working in the southwest province before, and I have just come to Beijing recently, where hydropower resources are abundant, and the main content of my work is to help build hydroelectric power stations." ”

After the other party finished speaking, Cheng Nuo asked everyone: "In other words, at the moment we are in the base in Sichuan, let's not talk about it during the dry season, the power resources are not only sufficient during the wet season, but also very rich, here I want to ask the family, is there any way to apply power resources to mining work well?" ”

As soon as these words came out, everyone immediately fell into deep thought, and they talked carefully about each other.

Unfortunately, in any case, it seems that it has little to do with mining, and even if it does, the substantial help is limited.

Seeing that everyone couldn't discuss anything, Cheng Nuo simply put down the teacup in his hand and said in a deep voice: "At the moment, whether it is ironmaking, steelmaking or steel rolling, we either have technology or equipment, but in terms of mining, we don't have enough accumulation."

But there are too many things we have to repair, many things can not be said to be no, but in the short term, the effect is too slow, and what we lack most at the moment is the development time, only to get through the current difficulties, can we have the opportunity to talk about the future, talk about the distance. ”

Shi Jin said curiously: "If we follow the opinion of Comrade Dean, then what can we consider next?" ”

Cheng Nuo said categorically: "Air compressor." ”

Afraid that the comrades would still have objections, Cheng Nuo finally specially added: "It doesn't need to be too big, 500 horsepower air presses are enough." ”

At this time, the use of domestic air compressors has been quite extensive, and the Newcomen steam pumping machine is a kind of air compressor, which can be used for mine pumping, and is also used for water supply in other aspects, and is also used for pumped storage, and the water wheel blades of the reservoir are used to drive various working machines.

The later Watt improved steam engine was also carried out according to this principle.

More recently, for example, Cheng Nuo was more in contact with the cotton textile industry, when there were two main factions in the cotton packing industry, one was traditional manual baling, and the other was machine baling.

In the production equipment, foreign foreign companies all use machine packaging, powered by electricity or steam, and the packaging machine has electric air compressor or cold air compressor, etc., and the efficiency of packaging is very high.

The principle of its operation is also very simple, it is ejection, vacuum and suction.

Taking centrifugal compressor as an example, after the gas enters the high-speed rotating impeller, under the action of the impeller blades, it follows the high-speed rotation of the impeller and flows to the impeller outlet under the action of rotating centrifugal force, and its pressure energy and kinetic energy are improved.

After the gas enters the diffuser, the kinetic energy is further converted into pressure energy, and the gas flows into the next impeller through the curve and cooler for further compression, so that the gas pressure meets the requirements required by the process.

The air compressor unit is composed of two parts: compressor and steam turbine, and Cheng Nuo has the experience of Watson Electric Appliance Manufacturing Factory.

"Well, for the sake of safety, on the one hand, we try to buy as many things as possible from Germany, focusing on the problem of air compressors, and on the other hand, we let Watson Electric Appliance Factory cooperate with Qiuxin Machinery Factory, one is responsible for one sector, which can also save us time to the greatest extent." Cheng Nuo decided.

Everyone in the audience nodded in agreement.

However, after everyone finished the meeting, Jiang Jiangzuo stayed and said cautiously: "Zhiyuan, blindly expanding the scale of production, the cost pressure will be great." ”

Cheng Nuo smiled: "If you talk about ironmaking, steelmaking or steel rolling, then I agree with your point of view, but the situation of mining is very different." ”

Jiang Jiang Zuo was puzzled: "How is it different?" ”

Cheng Nuo packed up the things on the table and explained: "Because our steel production structure is seriously unbalanced, the output of primary and intermediate products in the production greatly exceeds the production scale of finished products, that is, the actual output of ore and pig iron greatly exceeds the demand for steel smelting, and the export orientation of raw materials is very obvious."

That is to say, due to the relatively low technical content of iron ore mining, the capital investment is less, and because of the elimination of ironmaking, steelmaking and steel rolling, etc., the transformation of iron ore - capital can be directly realized, and the capital turnover is also relatively fast. ”

At this time, Jiang Zuo was even more puzzled: "If it is really like what you said, we will also squeeze in, and the price of steel will plummet, wouldn't we have to lose our heads?" ”

"Who said that? Gold diggers can't make money, but those who serve gold diggers are not necessarily. Cheng Nuo raised his eyebrows, took a sip of the teacup with the document in his hand, and said: "Now there are many iron ore companies that specialize in selling iron ore, such as Hubei Official Mining Bureau, Yufan, Baoxing, Luda, Fulimin and other companies, which just sell air compressors to them." ”

"It's also said, who doesn't want to mine more, even if the unit price is low, you can make small profits and sell quickly." Jiang Jiang Zuo suddenly realized.

Of course, what Cheng Nuo hasn't said is that these iron ore companies can still sell to Qiuxin after mining.

As for why, in fact, it is very simple, domestic large-scale iron and steel enterprises, such as Hanyeping, Longyan, Benxi Lake, etc., all have their own mines, and basically do not need external iron ore supply.

If you don't sell it to Cheng Nuo, you can only consider abroad.

As for the price, it is natural to be as low as it can be for you, especially after the end of World War I, when everyone uses less steel, the price of iron ore is the price of cabbage, and even how much it may sell and lose in a specific period.

The deep-seated reason is that steel production is distributed in a pyramid shape from raw materials to finished products, and the proportion relationship between each production link is seriously unbalanced.

The serious consequence of this is that primary products are heavily dependent on foreign market demand, and in terms of steel products, they need to rely on foreign imports, presenting a situation of large inflows and large exports.

What Cheng Nuo has to do is to balance them.

The air compressor is only the first step in the work of raw materials, and lifts, drilling machines, drilling machines, etc., all need to be worked on.
