The most "appetizing" dessert before eating Chinese and Italian meals - Downing demonstrated his hard-working masterpiece over the days: the steel converter.

The largest marble salon has become a technology salon. Here, there are many technological experts and skilled craftsmen. I am afraid that except for Queen Victoria and the Chancellor of the Exchequer, they all have their own understanding of engineering technology. They were suddenly attracted by the reduced converter carried out by Tangning's assistants. Tangning knows very well that he should explain a new process clearly, and the best thing is that you make it! It is best that even the components are transparent, so that the engineer can see the core points at a glance. If he explains the truth thoroughly, he will not have to study engineering technology by himself in the future, and just be an easy supervisor.

This small furnace is almost as tall as one person. The entire process is arranged in an array and almost occupy the center of the entire marble salon. Everyone has to stand aside. Even ordinary people will be very interested when seeing such exquisite and interesting small industrial equipment. The children brought by VIPs were even more stunned. Tang Ning reminded: "High temperature equipment, please hold the children, don't come and burn it."

Tang Ning asked his assistant to start the process of steelmaking and introduced the basic principles: "The steel we use is actually a carbon ferroalloy composed of iron and carbon. To make a carbon ferroalloy with suitable hardness and toughness, the key is to control the carbon content. In terms of the specific process, it is to use oxidation to control the carbon content, because after oxygen and carbon are burned, a gas - carbon dioxide is generated, which is easily discharged out of the oven. The key to mixing oxygen is to use compressed air, so that you can appreciate how the air produces magical effects."

Samuel Smith felt uncomfortable. He was very confident in this kind of steelmaking and hoped to occupy a large share of investment. Unexpectedly, Tangning made it public to his friends now. Don’t have too many rich people present to invest, and pray that they don’t have the vision...

Under the control of the assistant's wheel, coal and iron ore were loaded in a small car, and transported to the top of the blast furnace that was bulging between the narrow upper and lower middle, and then poured the raw materials into it quickly. The children were screaming with joy when they saw this interesting scene. The queen's youngest daughter, the three-year-old Princess Louise, simply slapped her face. This was so fun!

Donning didn't know what glass material he used, but could withstand the high temperature of 2,000 degrees. The audience could clearly see the entire burning process. The beautiful flames lit up their mood - it was too gorgeous. Samuel understood Donning a little. If he changed himself, if he made such an interesting demonstration model, he would have to be able to help but be so cool with his powerful friends.

As a person who has studied steelmaking technology, Samuel soon discovered a highlight. The thing Downing used to ignite the blast furnace seemed to be very hot. He asked decisively. Tangning smiled and said, "This is the legendary acetylene, which burns in pure oxygen more spectacularly."

Samuel was convinced that since acetylene has come out, the welding process is naturally under Downing's plan. It is a really exciting era of engineering. The production of acetylene is also quite easy. Calcium carbonate (limestone) and coal are the main raw materials for producing acetylene. First, calcium carbonate will be converted into calcium oxide, and coal will be converted into coke. Then calcium oxide and coke will react to form [calcium carbide] and carbon monoxide. Calcium carbide and water will form [acetylene] and calcium hydroxide.

The two pipes at the bottom of the furnace are connected to compressed air to control the degree of oxidation injected small amounts of potassium permanganate.

The beautiful transparent blast furnace, pig iron, steel, and steel slag can be seen clearly, and it conquered the hearts of technology experts in an instant. Such a demonstration is really impeccable.

The children were cheering because they saw the "red water", which was slimy and hot! When the fireworks when the steel splashed, they quickly retreated, and the scene was quite scary.

A total of twenty small steel blocks were produced by the small blast furnace. Tang Ning said that those who are interested in investing in his steel mill can take one or two pieces to study after cooling to see if this is high-quality steel.

The patent of steel converter furnace must be gone. So many famous powerful people watched this great invention debut for the first time. Who can deny that our radio genius invented a large-scale industrial destruction technology? What everyone doesn't know is the trick that Tangning is playing. These iron ores do not contain phosphorus. Only Wales and Sweden have such iron ores. Most of the iron ores are phosphorus-containing and require dephosphorization process, such as: adding lime. This little secret can cause Tangning's technology to leak out and will have a long time to imitate them to obtain steel that is inferior to phosphorus-containing.

The eradication of the iron factory and unification of the world is just around the corner. This time, the name of the new factory is "British Steel Company" and BS.

The dinner finally started. Faced with inquiries from people who were interested in investment, Downing said that he would build the largest steel mill in the UK and raise one million pounds. Everyone should first express their investment intentions and use 10,000 pounds as the lowest subscription amount. Finally, he would consider the structure of the shares in a comprehensive manner.

Since its opening on May 1, the British Telegraph Company has rented more than 1,000 telegraph machines or typewriters per month on average, with an estimated annual turnover of up to 1 million pounds. Lionel's 25,000 pounds investment has become an annual income of 25,000 pounds. In his eyes, Downing has become a god-like chicken who can lay golden eggs. Therefore, he is quite optimistic about the future of the new company and said directly, "Look at how many shares can I occupy at most?" Samuel also expressed a similar view. He has been eyeing this new company for a long time!

Tangning regretfully said that he is no short of funds now, and what he values ​​most is investors' experience in metallurgy. Therefore, Mr. Samuel must be the second largest shareholder, and the share that everyone can invest cannot be too high. Tangning personally has to occupy 60% of the shares. This time, he wants to make money hard, and the steel king is right in front of him.
