Franz, on the other hand, preferred the Bessemai method, which later became known as the converter method. Of course, Bessemer has taken detours, and he does not intend to repeat them, such as the problem of acid-alkaline properties.

The acid converter process is unable to remove sulfur and phosphorus, which results in huge waste and quality degradation. Whereas, the alkaline converter method, which uses a converter with an alkaline lining to process high-phosphorus pig iron, dumps slag to remove sulfur (this process is slightly complicated and will not be written in detail).

Why didn't Franz adopt the more efficient Martin method of later generations? Because the upfront investment of the Martin method is too high, and the cycle is long and the reaction time is slow, the types of steel that can be manufactured are few, the energy consumption is serious, and the inherent shortcomings cannot be overcome, and the upper limit is too low.

Converter steelmaking, on the other hand, is obviously more flexible, which is suitable for a country like Austria, where steel companies are very fragmented. With the alkaline converter process in Austria, steel production can be increased by a factor of 8-10.

However, given the current market conditions in short supply, the price of steel will not fall too much, and Franz can take the opportunity to make high profits and expand production capacity, so as to occupy the market one step ahead of other powers.

In fact, Bessemey's method has been completed a long time ago, but there are still many flaws, and the timing is not right.

Platner Karl Friedrich, a talented metallurgist from Saxony, and Radten Bachel, an Austrian, born in Steyr, worked as a cleaner at the Vienna Engineering Academy for two months before moving to Switzerland to become a well-known engineering expert and one of the founders of mechanical engineering.

In fact, Franz originally planned to invite Krupp and Siemens, but the former had a prosperous business and was in the limelight, so he refused to accept Austria's invitation and committed a "traitorous act".

The latter was because he stole a donkey and pulled pegs, and he watched when others fought, but as a result, they ran away and he went to prison. It was obviously a duel between two officers, but it was two small soldiers who ended up in prison, one of whom was Siemens.

In fact, it was not difficult for Franz to get it out, but Siemens was a prisoner of great interest, because even in prison, he continued to study science and technology, and his inventions were even valued by the Prussian military.

Finally, also under the operation of some Junker nobles, he was pardoned by a decree of amnesty personally signed by King Frederick William IV of Prussia.

If Franz gets this out at this time, it will definitely become a big news, and it is reasonable for the Prussian military to directly kill this great inventor in human history in order to avoid financial enemies.

Platner and Batchel are no worse than these two famous geniuses, but there are some problems with the direction of their research.

More than 100 years later, the top blowing converter technology is one of the products of the combination of the two inventions.

The two were experts in metallurgical engineering, and with the cooperation of a group of professionals, they quickly figured out Bessemey.

As for the alkaline lining, although the two did not understand what Franz was going to do, this did not prevent them from working. The new alkaline refractory bricks are fired with dolomite mixed with tar from the maturated material at high temperatures.

After a few experiments, they discovered the brilliance of this alkaline furnace lining, and they couldn't help but admire this genius who grew up in the palace.

When Franz returned to the factory where they were experimenting, the two had already taken their notes and benches.

"Grand Duke Franz, the experiment is complete, and this completely new technology will cause an industrial revolution. The existing blower may not be able to meet your needs, so we have invented a completely new blower. ”

Franz looked at this so-called new blower, in fact, the technology content is not high, that is, a few blades are added on the basis of the original blower, and the power becomes a steam engine, and the only design beyond this era is the air duct.

This has to admire the wisdom of mankind, and historically this industrial blower was not invented by the Americans until 1867.

The invention of this high-efficiency fan can also further increase steel production, of course, at this time, the air is blowing, and there is still 78% useless nitrogen in it, which is still a huge waste.

However, industrial oxygen generators need the help of electricity, and electricity is still a scarce resource at this time.

"It's a great invention, but the efficiency of the steam engine is too low, and the Navy has a steam turbine technology that can make your invention 500% more efficient."

“500%？！ Oh, my God! What's the use of blowing in so much air, it's mainly nitrogen, and it can't be burned. ”

"Then why don't you try to remove the nitrogen and inject pure oxygen directly?" Franz said that after all, he knew where history was going, and the top-blowing converter method is still the most widely used steelmaking method to this day.

And the Austrians after World War II also used the inventions of these two.

"Pure oxygen? So how much water do we need to electrolyze? Platnay immediately came up with the idea of electrolyzing water to produce oxygen.

"That's a waste of electricity." Batchel said that it was clear that the price of electricity at that time was distressingly expensive.

"When the steam turbine arrives, maybe you'll find the answer in it."

Franz's words made the two professors even more interested in the mysterious steam turbine.

In fact, modern American aircraft carriers use steam turbines to drive power generation, and it will not reduce its own thermal efficiency, but also help reduce fuel consumption, which is a good way to kill N birds with one stone.

In fact, Franz thought too much, at this time the science of electricity was still in its infancy, not to mention that the two of them were engaged in metallurgical machinery, even electric power experts could not do it.

"Is that machine really as amazing as you say?" The two of them couldn't help but ask with confusion and anticipation.

"Let's wait and see." Franz did not give a clear reply, because he knew that these people who were engaged in engineering were very believing, and even if they were told about smallpox now, these people would not believe it.

"Now that the technology is nearing maturity, it is ready for production. Our country will definitely be able to achieve self-sufficiency in steel, no, we can eat the entire German steel market. The two professors gave their own judgments.

"No, I don't plan to promote this technology for the time being, it will only be used in the royal factory, and this technology needs to be further improved."

In fact, Franz just wants to make a wave of technological dividends first, and it is indeed a good idea to sell patent rights, but you can't stand it, there are always rogue states that have a way.

For example, after the historical Bessemer registered a patent in the United States, an American immediately jumped out and said that he had invented this method.

In order to invent Bessemer's steelmaking method, the American conducted secret research on his own, and did not jump out until the Bessemer method became popular in Europe.

The American mystery inventor, who shouted that Bessemer was a thief and a liar, immediately received the support of the U.S. government, canceling Bessemer's patent and granting it to the mysterious man instead.

Soon the mysterious man went bankrupt and had to sublicense the patent to the U.S. government, which not only obtained Bessemer's patent without spending a penny, but also got a layer of wool from the U.S. steel company every year.
