After leaving the paper factory and the Institute of Power Machinery, Dang Aiguo led the Foreign Teaching Group of the Central University to transfer to other small factories around Luoyang. Although it was just a small factory for Dang Aiguo, for people during the Three Kingdoms, Dang Shenxian seemed to particularly like "big scenes".

After wandering around Luoyang, Dang Aiguo finally took the students to the Heyi Workshop in Xingyang for a day. After they learned how steel was made, they announced that the off-campus teaching activity was successfully concluded. Everyone disbanded on the spot and went whatever they should do. Those who want to go back to their hometown to get married can also go back - of course, female students are not allowed.

At the Heyi Workshop in Xingyang, students just briefly saw the original iron-making blast furnace and other equipment of the Fanhe Workshop, as well as the newly built coking workshops, mechanical forging workshops, and mechanical processing workshops nearby. Of course, the "workshop" is just the customary name of the old craftsmen who have worked here all their lives. According to the party's patriotism and the country's usual atmospheric command, all of these new workshops are called "factories".

But in fact, the scale of these new factories is even barely considered "workshops", which is basically the same as that of individual small workshops in later generations. However, the meal has to be eaten at a glance. In the heart of the Party and Patriotic Republic, I really plan to focus on these small workshops and develop them into independent factories. Now it seems that the prospects are still optimistic.

In terms of iron smelting blast furnaces, the Party Patriotic actually couldn't put forward any constructive opinions. The only thing that could be done was to allocate funds to encourage experimental innovations in improving iron smelting processes. As for the iron smelting method, the "steel-frying" method that is being used in Heyi Workshop is now very advanced, and he can only try to design machinery to replace human stirring and heated to liquid or semi-liquid pig iron.

The greatest achievement of the Party’s patriotism in iron smelting was actually the “invention” of bellows, providing the chemical theoretical basis for iron smelting, “inventing” forging machinery, and proposing the use of coke to smelting iron. In addition, he also “discovered” a variety of metal elements - although he only knew some elements, it had no use at all.

In fact, it is still hard to see what the coke iron smelting has now. After all, this is equivalent to a significant improvement in the production process and it is impossible to act rashly. Therefore, the Party Patriotic simply allocated a small blast furnace from the Heyi Workshop to experiment with coke iron smelting and summarized technical experience. Perhaps, in two or three years, coke iron smelting can be put into use; in five or ten years, coke iron smelting technology will be considered initially mature?

However, when it comes to talking about its greatest contribution - not only in iron smelting, but in various industries, Dang Aiguo believes that it has established research institutes in various industries. For example, in an important industry that can be called the lifeline of the country, Dang Aiguo has established a number of scientific research institutions such as the Materials Research Institute, Metallurgical Technology Research Institute, Alloy Research Institute, Forging Research Institute, Casting Research Institute, and Machining Research Institute.

Many people expressed their discomfort about this, especially those families, who believed that the Party Gods were wasted money and were extremely stupid and prodigal. On the contrary, the people did not have much doubt about this, but in their understanding, everything the Party Gods said was right, and they must firmly implement the instructions of the Party Gods. Because the Party Gods will not make mistakes, they do not understand it because the Party Gods’ intentions are too profound and cannot be understood by ordinary people.

Anyway, no matter what, from the results, the production efficiency and capabilities of the various factories established by Dang Paiguo, as well as the two major factories renovated based on the papermaking workshop of the Kwan and the Heyi Workshop in Xingyang, have indeed improved significantly - although this is indeed nothing to do with the research institute that can only "burn money".

Because the time is still short, the new iron-smelting blast furnace has not been built yet. However, the original production equipment slightly controlled the production process, so the steel output and stability have been improved to a certain extent. Moreover, because the forging ability of machinery is much more effective than manpower, the cast steel ingots are forged by huge mechanical forging hammers, and the mechanical properties are much better than in the past.

The newly built forging factory and coking plant in Heyi Workshop are close to each other, and the steam boilers used in the forging factory to lift huge forging hammers weighing thousands or even thousands of kilograms are one for burning coal and coke, and the other for burning gas. The source of this gas is naturally the coke oven gas generated during the coking process.

Not only coke iron smelting, but in fact, the technology of using coal coking is still being continuously experimented and improved. However, the Party Patriotic launch of coking projects is much bolder than changing to coke iron smelting technology for blast furnaces. Because coke is not refined well, it can be burned as charcoal. Anyway, the steam machinery of the forging factory next to it and the mechanical processing factory not far away all require a lot of fuel.

Because coking work is almost day and night, but the forging factory cannot allow workers to work day and night, the gas in the coking factory cannot be consumed at all. In addition to supplying steam engine boilers to the forging factory nearby, a large bathhouse has also been established, providing hot water 24 hours a day so that the craftsmen in the Heyi Workshop can take a bath at any time.

But even so, a lot of gas has to be burned in vain - just like the accompanying gas without mining value will be burned in an oil field. The reason why this is wasteful is because the current gas storage technology is about zero. This is mainly because the gas pressurization technology and storage material strength and processing technology are not up to standard. Moreover, the gas transportation technology is also a problem. The reason why forging plants and bathhouses are built next to coking plants is because current technology can only achieve short-distance safe transportation.

Although it is indeed possible to manufacture heavy steel tanks for storing coal gas, and the steam engine can also push the piston to pressurize the gas and fill it into the steel tank, it is not cost-effective to store high-calorie fuel such as gas so much. And there is another problem, that is, the current steel machining capabilities are very weak, and steel tanks like this can only be directly formed by casting - just like the party's patriotic cannon.

But casting is also a profound science. Even later generations cannot completely avoid casting defects. It is even hard to say what the quality of casting parts is now. For example, the casting cannons of the Party and the country are used in fear. Every time they fire a gun, they have to check whether there are cracks in the cannon body, and summarize the problems that cannons are prone to casting, let alone steel tanks that store high-pressure gas.

Therefore, now Dang Aiguo has only made a few roughly qualified steel tanks, which are used when it is necessary to temporarily store hydrogen and oxygen produced by electrolysis. As for things like chlorine, he dare not store them, and they are directly passed into water and converted into sulfuric acid. What a joke, using the unreliable steel tanks to store chlorine, isn’t that equivalent to storing toxic gas bombs that may have leaked at any time?

Although the Party Patriotic is not afraid of poison gas, if his students are poisoned and died, he probably will have the desire to die. He felt that he could not hold it because of this. It is precisely because of this that the Party Patriotic has always emphasized that human lives - especially the lives of the most precious talents, which are more important than anything else. This is not humanism, it is purely because scarce talents really cannot afford to die, and they cannot afford to die!

After presiding over the manufacturing of relatively large mechanical forging equipment, the country's steel output is an important indicator that restricts development. Dang Patriotic has already gained a profound understanding of why it is the mechanical era. After entering the era of machinery, it is even said that it has not yet entered the era of machinery. But when he wanted to create a batch of larger machinery, he found that high-strength large steel materials were really lacking.

Because the steel was jammed, most of his materials were wood in various machinery! Only in the mechanical forging equipment of the forging factory did he use high-quality steel that could occasionally be successfully produced. Moreover, these steels were hand-forged by blacksmiths. Although they were not forged according to the standards for creating treasure knives, they also greatly improved the mechanical properties.

Dang Aiguo also wanted to make forging machines made entirely from steel, but the current welding technology is equal to zero. Even the riveting technology was only tried to apply after Dang Aiguo proposed it, so he only changed the place in the forging equipment that could be replaced with steel.

Because the mechanical processing ability of steel is too weak, the design of the mechanical forging equipment of the Party Patriotic country is very similar to the Soviet "big brother" who is stupid and black. He has no choice but to do this, because most of the parts of the mechanical forging equipment can only be completed through casting, so it can only be designed into the simplest and straight geometric shape when designing, even if some performance is sacrificed for it. Moreover, after casting, the blacksmiths have to hold small hammers to forge the surface and beat it to a qualified size before they can barely assemble them together.

It is precisely because of the limitation of processing capabilities that ancient machinery has basically always been wood. Occasionally, some machinery made of metals such as gold and silver are mostly small and exquisite toys. After all, easy processing of gold and silver means that the mechanical strength is not high, and such soft things cannot be used in factories.

What's more, if a factory really uses gold and silver as equipment, maybe in a few days the workers will dig one piece and dig it up, and it will be full of holes. Even if someone takes strict supervision, the workers can't stand it every day and use a knife to secretly scrape gold and silver powder on the equipment and get it home. "As long as the hoe is swung well, it will not be dug without corners", it means this.

Of course this is just a joke. In fact, due to the mechanical processing ability, Dang Mai has many equipment that are really made of gold and silver. Now whenever metal parts are needed, Dang Mai’s first reaction is to see if it can be made of gold and silver. In any case, turning these wealth into scientific research equipment is much better than letting the emperor store them in the warehouse and wait for hair to grow.

However, gold and silver are too soft after all, and it is okay to make some precision instruments, which is simply "overwhelmed" - non-ferrous metals that are easy to process, such as copper and tin, also have this problem. Therefore, Dang Paiguo has always focused on machining factories and machining research institutes, urging them to upgrade their processing capabilities from wood and non-ferrous metals to steel processing as soon as possible.
