MTL - The War Court and Lap Pillow, Austria’s Mandate of Heaven-v3 Chapter 54 steelmaking method

【War court and knee pillow, Austria's destiny】【】

But what Franz likes is the Bessemer method, which is also known as the converter method in later generations. Of course, he does not intend to repeat the detours that Bessemer has taken, such as the problem of acidity and alkalinity.

The acidic converter method cannot remove sulfur and phosphorus, which causes huge waste and quality reduction. And the basic converter method, which uses a converter with a basic lining to process high-phosphorus pig iron, dumps **** to discharge sulfur...

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

Converter steelmaking is obviously more flexible, which is just right for a country like Austria where steel companies are very scattered. After adopting the alkaline converter method in Austria, the output of steel can be increased by 8-10 times.

However, given the current market situation where supply exceeds demand, the price of steel will not drop too much. Franz can take the opportunity to earn high profits and expand production capacity, thereby occupying the market one step earlier than other powers.

In fact, the Bessemer method has been completed long ago, but there are still many defects, and the timing is not right.

Plattner Karl Friedrich, who was in charge of research on converter steelmaking, was a genius metallurgist from Saxony, and the other was Redten Bacher, an Austrian born in Steyr, who had As a cleaner at the Vienna Academy of Engineering, he audited for two months, and then went to Switzerland to become a famous engineering expert and one of the founders of mechanical engineering.

In fact, Franz originally planned to invite Krupp and Siemens, but the former's business was booming and the limelight was strong, so he refused to accept Austria's invitation and acted as a "traitor".

The latter is because of stealing donkeys and pulling out prongs, and others fought him to watch, but they ran away and he went to jail. Obviously it was a duel between two officers, but the last ones to go to prison were two soldiers, one of whom was Siemens.

In fact, it is not difficult for Franz to fish it out, but Siemens is a prisoner who has attracted much attention, because even in prison, he is still researching science and technology, and his inventions are even valued by the Prussian military.

In the end, under the operation of some Junker nobles, he was pardoned by an 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. In order to avoid the enemy, it is reasonable for the Prussian military to directly kill this great inventor in human history.

The level of Plattney and Bachel is not inferior to these two geniuses who have left their names in history, but there are some problems with the direction of their research.

One hundred years later, Yiqi Juechen's top-blown converter technology was one of the products of the combination of their inventions.

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

As for the alkaline furnace lining, although the two of them didn't know what Franz was going to do, it didn't prevent them from working. The new basic refractory bricks are fired by mixing dolomite and tar at high temperature.

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

When Franz came to their experimental factory again, the two had already taken the notes and the bench.

"Grand Duke Franz, the experiment has been completed. This brand new technology will cause an industrial revolution. The existing blower may not meet your needs. We have invented a brand new blower."

Franz looked at this so-called new type of blower. In fact, the technological content is not high. It just adds a few blades to the original blower, and the power becomes a steam engine. The only design beyond this era is the air duct.

This has to admire the wisdom of human beings. Historically, this kind of industrial blower was not invented by Americans until 1867.

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

However, industrial oxygen concentrators 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. The navy has a steam turbine technology that can increase the efficiency of your invention by 500%."

"500%?! My God! But what's the use of blowing in so much air, it's mainly nitrogen, and it can't burn."

"Then why don't you try to remove the nitrogen and inject pure oxygen directly?" Franz said, after all, he knew the direction of history. The top-blown converter method is still the most widely used steelmaking method today. .

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

"Pure oxygen? How much water do we need to electrolyze?" Plattner immediately thought of electrolyzing water to produce oxygen.

"That's a waste of electricity." Bacher said, obviously the electricity price at that time was so expensive that it made people feel distressed.

"After the steam turbine arrives, maybe you can find the answer from it."

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

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

In fact, Franz was thinking too much. At this time, electricity was still in its infancy. Not to mention that the two of them were engaged in metallurgical machinery, even an expert in electricity could not do it.

"Is that machine really as magical as you said?" The two couldn't help asking with doubts and expectations.

"Let's wait and see." Franz didn't give a clear reply~www.novelbuddy.com~ because he knows that these engineering people pay attention to seeing is believing, even if you tell them smallpox now, these people Nor would I believe it.

"Now this technology is close to maturity and can be put into production. Our country will definitely be able to achieve self-sufficiency in steel products. No, we can eat the entire steel market in Germany." 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. This technology still needs to be improved."

In fact, Franz just wanted to earn a wave of technological dividends first. Selling patent rights is indeed a good idea, but if you can't stand it, there is always a rogue country that has a way.

For example, after Bessemer registered a patent in the United States in history, an American immediately jumped out and said that this method was invented by him.

In order to invent the Bessemer 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 mysterious inventor, who called Bessemer a thief and a liar, immediately got the support of the US government, canceled Bessemer's patent rights and granted it to the mysterious man.

Soon the mysterious man had to transfer the patent rights to the U.S. government because of bankruptcy. So far, the U.S. government has not only obtained Bessemer’s patents without spending a penny, but also obtained a layer of patents from U.S. steel companies every year. wool.
