In fact, Marin has to deal with not only Essen, but also Dortmund, which also produces coal, is also an imperial city. Unlike Bremen, the Hanseatic city that had been annexed by Marin, although these two cities were unwilling to submit to Marin's rule, they did not openly form an alliance with others against the North Sea State like Bremen.
Therefore, Marin was really helpless for this kind of city that did not cooperate but did not turn his face. If it was a city with few resources, Marin would ignore it. However, both Essen and Dortmund are cities with large coal mines, and the coal mining industry is very developed. This is not good for Marin, who is aiming to round up coal in the Ruhr area.
But what makes Marin a headache is that the two cities just don't cooperate, but they don't confront each other, so Marin can't find an excuse to send troops to annex them.
However, Dortmund is okay. Essen's behavior of manufacturing weapons and selling them to various princes has already touched Marin's bottom line. It's just aggrieved that Marin still can't use this as an excuse to attack. why? Marin is not at war with those vassal states, why do you think it is not good for Essen to sell them weapons? Could it be that you have bad intentions towards the princes? If you break out rashly or even send troops, it will be considered as an excuse to those princes.
Therefore, Marin can only use other methods to deal with Essen. Before, Marin thought of blocking the roads around Essen and imposing an embargo to kill Essen's handicraft industry.
But Essen turned around and went to the Imperial Council to complain to Marin. Marin was unreasonable about this matter, and coupled with the pressure from the princes, he had to let it go. Even the emperor sided with Essen this time. Because, the right to travel freely in imperial cities was originally bestowed by the emperor. As long as the other party pays the toll honestly and does not fund Marin's war opponents, Marin has no reason to prevent Essen from doing business with the outside world.
Helpless, Marin had no choice but to give up temporarily. But this time I met this guy named Krupp at the Krumhorn Steel Plant, and the other party was still from Essen, and he had some festivals with his hometown. Marin quickly thought of using him to open a steel plant, A way to compete with Essen and poach people with high salaries. This is a purely commercial behavior, reasonable and legal, and no one can blame it.
Moreover, Malin specially pushed the young man Krupp to the front desk and borrowed his name, clearly wanting him to come out and do things.
In addition, it is also very clever for Marin to target those blacksmiths. After all, for a blacksmith, working for your arms dealer in Essen is as much a job as working for a Krupp steelworks. Whoever gives more money will hang out with whoever.
As for the weapons dealers in Essen who raised their salaries to grab people? Okay, whatever you want, I, Ma Jianlin, Ali Huateng, Lin, have never lost money...
Even if it loses money, the blacksmiths of the Essen arms dealer will be hollowed out!
Marin can not only provide higher salaries to the blacksmiths in Essen,
Moreover, housing can also be provided to realize the good benefits of housing distribution. In addition, the cafeteria will also provide fast-food meals for future generations, with two meat and three vegetarian meals per meal, so that the masters will be well fed. Moreover, the taste far exceeds the German local food of this era. He didn't believe it anymore, those blacksmiths would not be tempted.
Of course, they can be poached by themselves, or they may be poached by others with high salaries. Therefore, the core technical positions of the future Krupp Iron and Steel Plant will still be mastered by Beihai's own craftsmen. For example, the process of blast furnace ironmaking must be operated by Marin's own people to avoid technology leakage.
However, when the molten iron is cast into ingots and turned into utensils, a blacksmith is very much needed. At this time, the blacksmiths dug by Essen will come in handy. Casting cannons and so on, if you don't need them, you dare to use them. However, there is no need for technical secrecy to build agricultural tools, just let them come.
In addition, Marin will also develop a project that he has long wanted to develop-steel wire!
What to do with steel wire? Of course it is reinforced concrete!
Among the steel bars, the thick steel bars are the best to manufacture, and the molten steel can be directly cast in the long grooves. Thin steel bars are troublesome, and can be obtained by processing thick steel bars.
However, the prestressed steel wires that bind the thick and thin steel bars in reinforced concrete, commonly known as wire rods, are more troublesome.
In later generations, if you get a wire drawing machine, you can draw steel bars that have not been cooled or tempered and softened to get the required steel wires.
However, there is no wire drawing machine in this era! If you want to get iron wire, you have to rely on blacksmiths to use drawing boards and other tools to draw red-hot iron bars into wires.
This is a purely technical job, and it is difficult to learn without many years of experience in blacksmithing. Marin planned to let them pull the steel wire after digging back the blacksmith from Essen. Our own blacksmiths first produced low-carbon steel and carbon spring steel bars, and then used drawing boards and other tools to draw them into wires for the blacksmiths who dug them. In this way, the prestressed steel wire needed to make reinforced concrete, that is, the wire rod, is obtained.
Needless to say, the role of wire rod is an important part of reinforced concrete, and it is also an important guarantee for the tensile strength of reinforced concrete. As long as the production of wire rod is sufficient, Marin will start to use reinforced concrete to build city walls and fortresses. In this way, even if the opponent brings heavy artillery, there is nothing they can do. After all, reinforced concrete is quite resistant to conventional weapons.
You must know that even during the First World War when artillery technology had reached its peak, facing the Maginot Line of reinforced concrete structure, the army as powerful as Er Dezi had to choose to attack from Belgium. Of course, in the Sandezi period, because of the armor-piercing bullets of tungsten alloy, there was a way to deal with reinforced concrete. Otherwise, Mustache wouldn't have exchanged so many German-style equipment and bald Jiang for tungsten ore, and even sent military advisers to help with training. But during World War I, reinforced concrete was really unsolvable. A neutral country in Belgium, because it can bypass the reinforced concrete Maginot Line, it was pushed flat by Er Dezi.
...
Therefore, Marin built the Krupp Steel Works in Essen not for casting guns or other weapons, but for drawing steel wires.
With steel wire, Marin can not only make authentic reinforced concrete (I have used iron wire before, but it is a low-profile version, and the tensile strength is not good), but also can consider making steel wire spoke hubs for bicycle wheels. Bicycle wheels with wire spoke hubs can absorb the impact of the road very well. Through the deformation of the steel wire, the purpose of buffering can be achieved. With rubber pneumatic tires, it can make riding very comfortable.
In addition, steel wire spoke wheels can also be used for carriages with small load capacity. In this way, passengers can be more comfortable. Moreover, it also saves steel materials, making the wheels lighter.
Before that, because the elasticity and restoring force of iron wire were not enough, it would not work for steel wire spoke hubs, and it was easy to deform and fail to recover. Therefore, it cannot be applied. Now, Marin intends to use carbon spring steel to make high-elastic steel wire, and its application range is much wider.
Of course, because it is purely hand-drawn, the output must not be high, and the price must be expensive. But this is just the beginning. In the future, Marin will definitely let people develop a steam engine-driven wire drawing machine. Once the wire drawing machine is put into use, the steel wire or something will be a mass-produced cheap product. At that time, bicycle wheels and carriage wheels with wire spoke hubs will inevitably become widely used in life.
Therefore, the essence of the steel factory that Marin asked the lucky guy Krupp to build is a factory that produces steel wire. Blast furnace ironmaking and reverberatory furnace steelmaking are all paving the way for the final wire drawing process...
