Since being taught to be a human being by the cruel reality, how to solve problems has become a big stone in Jochen's heart. There are some things that Jochen can solve with his mouth open and spend money, and the problem of the composition ratio of aluminum alloys Jochen throws the problem directly to the Royal Prussian Academy of Sciences.

Jochen asked them to conduct research on the addition of other metallic elements to improve the hardness and strength of aluminum, and as for the cost of the research, he could fund it.

The efficiency of the Royal Prussian Academy of Sciences is not bad, and its physical materials research laboratory has indeed made aluminum alloys that can meet the needs of use after a huge composition ratio test.

These aluminum alloys were used in the development of airships and aluminum alloy engines, and because they were produced in the production method of the real yàn room, the prices of these aluminum alloys were all surprisingly high, which is why Jochen and Zeppelin complained that these things were piled up with gold marks.

However, because it needs to meet the needs of research and experiments, the demand is not too large, and the output prepared and produced in the real yàn room can also meet the demand, although it is a little expensive, but this money can still be paid by Yoheng.

However, do you want to enter mass production and meet the needs of large-scale practicality? The beauty you want.

Aluminium is the third most abundant metal element on the earth, and the mining of bauxite began as early as 1873, when it was the French who ate crabs first.

The technology of electrolytic aluminum was invented by the Americans as early as 1886, and the technology of Bayer method to make bauxite into alumina was also invented 6 years ago, but it is very rare to refine aluminum, and the reason is that smelting aluminum requires electricity, a lot of electricity.

At present, electricity itself is not widely used, and it is very difficult to promote the aluminum smelting industry.

Although the use of electricity is gradually expanding in various countries, the application of electricity is mainly focused on the demand for lighting, and some people with a long-term vision have also begun to use electricity as an energy source for industrial production.

However, the smelting of aluminum, which consumes a lot of electricity, is still not in the consideration of various countries, and aluminum smelting will still be a high-energy consumption industry even if electricity is fully distributed in the future, let alone now. Building a large number of power plants to produce huge amounts of electricity is obviously a rather uneconomical deal on a metal as aluminum, which is not strong enough and has little industrial significance.

Only Jochen knew the great value of the aluminium smelting industry.

With aluminum alloy, Maybach's research team will be able to be more confident and bold in weight, and the engine with more horsepower will be just around the corner, and after breaking through the technology of V-shaped staggered arrangement in the future, the situation that the German aero engine in World War I using in-line and being thrown by the British V-type engine will not be repeated sooner.

Not only can aero engine technology be greatly developed, but even the army can also benefit from it, the aluminum alloy diesel engine B-2, the engine of the famous T34 medium tank, basically anyone who knows a little bit about military affairs knows this outstanding design, and even better is that Jochen has seen a cross-sectional view of this thing and a simulation animation of the running demonstration in his previous life.

Although the specific parameters are not clear, it is estimated that it is not a big problem to come out of a similar diesel engine according to that way of working. It is not required to be able to provide 500 horsepower like the B-2, and half of it can already make the performance of the tank far beyond the level of World War I!

Moreover, the value brought by the development of aluminum smelting technology is not only the aluminum alloy itself, but also the stimulation and promotion of the entire electrification era.

The British led the steam age brought about by the first industrial **, and although the empire, which started late, caught up with Britain through its own efforts, its own heritage was still far behind.

Then only by leading the electric era brought by the second industrial **, making Germany a leader in science and technology, and letting other countries catch up behind is the direction of Germany's development.

The industrial application of electricity is an important part of this goal, and the emergence of production tools using electricity is only one part of it, and the construction of high-energy consumption industries such as aluminum smelting, which requires direct participation in the production of electricity, can greatly stimulate the demand for electricity consumption.

And Germany now has a good start, with Tesla, a mad scientist in the field of electric power applications, constantly developing machinery and equipment that uses electricity, Parsons, a leader in the field of steam turbines, constantly improving the power generation capacity of generator sets, and Miller and Dobrovolsky, two pioneers of power transmission systems, constantly improving the efficiency and transmission distance of power transmission.

Germany has already won at the starting point, so there is enough basis for some power-intensive industries to continue to stimulate it, and the Stuttgart aluminium smelter where Jochen is now located was built out of this demand.

The alumina powder from the furnace was loaded into carts and transported to the second associated shed, where Jochen followed.

Unlike the huge melting furnace in the first shed, there were only a few huge tanks, and truckloads of alumina powder were poured into the electrolytic cell, then cryolite powder was added, and the technician pulled down the electric switch, and powerful direct current poured into it.

Molten cryolite as a solvent, alumina as a solute, with high-quality anthracite as the carbon body as the anode, molten aluminum as the cathode, after a strong direct current, the chemical reaction begins in the electrolyzer at high temperature, although there is no high-temperature smelting furnace here, but the high temperature of nearly 1000 degrees Celsius still makes it no cooler than the previous factory shed.

Under the chemical reaction, the products of the anode are mainly carbon dioxide and carbon monoxide gas, which contain a certain amount of harmful gases such as hydrogen fluoride and solid dust, and the product of the cathode is silver glittering molten aluminum. After the molten aluminium is extracted, it is purified and clarified in a holding furnace, and finally cast into large pieces of silver ingots.

Looking at these aluminum ingots that have not been completely cooled, Joheng is very satisfied, although the current electrolyzer uses flue gas that cannot be treated, pollutes the environment strictly, mechanization is difficult, labor intensity, is not easy to large-scale, and the output of a single tank is low, etc., and the self-baking tank will inevitably be eliminated in the future.

However, judging from the current technical conditions, the advantages of simple equipment, short construction period and low initial investment are the best choice now. Besides, Jochen didn't know what the structure of the common pre-brewing oven would be in the future, and even if he wanted to, he wouldn't be able to use it.

The Stuttgart aluminium smelter is now able to produce more than 100,000 tonnes of finished aluminium ingots per year, which need to be further processed before they can be used as aluminium alloys.

However, this is only a base for aluminum smelting technical workers in Jochen's heart, although a variety of supporting related industries are very complete, and the construction of related facilities is also very complete, but as Stuttgart, which is located in the southwest of Germany, it is still a little inconvenient to meet the annual output of millions of tons.

The annual production of 100,000 tons is now enough to meet the needs of aviation and power technology research and application here, so Jochen is not ready to continue to expand the production scale here.

Bauxite in Germany needs to be imported, and larger-scale production requires more electricity, so the next step is to build a larger-scale smelter in western Germany, close to ports and coal-producing regions, and the workers trained here will help the new plant to get up and running quickly.

In this way, a complete industrial supporting system for large-scale aluminum smelting has been established in Germany step by step.

While the Germans were slowly developing their own power industry system at their own pace, the British were a little unable to sit still.

"Why are these Germans so stubborn? If we can't take the railroad to the Persian Gulf, we will ignore all our other mentions? We're ready to give the whole of Helgoland back to them! "His Excellency the Marquess of Salisbury is a little angry.

"Your Excellency, there has been no progress on the French side in the negotiations on the Sudan and Polynesian questions, and the attitude of the Americans is not clear, although the Americans have agreed with us on the Panama issue before, it is clear that the Americans do not want to come into direct conflict with the French." Chamberlain reported with some helplessness.

"Your Excellency, we ...... the Germans' request to build a railway to the Persian Gulf," Chamberlain asked with some hesitation.

"They can't be promised that once the railway is built, the Germans will be able to run through the entire Middle East, and they will be free from the restrictions of the Suez Canal, so that the Germans will have free access to the Indian Ocean." The Marquess of Salisbury refused.

"But the Russians are now intervening, and St. Petersburg has already made an initiative to Germany and France to make a joint request to our country for an end to the war with the Boers. The Germans are now becoming more and more careless in their talks with us, and I fear that if they fail to achieve their goal, it is quite possible to agree to the Russians' offer. ”

"These Germans probably are stalling for time when they see this situation, and they want to wait for us to bid higher or Russia, France! These Germans, like their northern relative, want to take advantage of the opportunity to blackmail us. ”

"These Germans have really picked a good time, but we can't do anything better now, Your Excellency." Chamberlain persuaded.

"How has the empire ever been so powerless?" Salisbury sighed: "Maybe we need a meeting of the four countries to get the Germans to take a stand." ”

"So do you want to note the ambassadors of the three countries now? In what name? ”

"Just ......," Salisbury was about to speak, when suddenly there was a sharp knock on the door.

"Come in, what's the matter?"

"Your Excellency, Claude, the minister to the Qing Dynasty, sent a telegram asking China to send warships to the Bohai Sea, and the ministers of the United States, Britain, France, Germany, and Italy also asked their countries to send warships."

"Joseph, it seems that we have to send a note to a few more ambassadors, in the name of negotiating to resolve the Qing issue." R1152
