The most "appetizing" dessert before eating a Chinese and Italian dinner - Downing demonstrates the masterpiece he has been painstakingly working on these days: the steel conversion furnace.

The largest marble salon has been transformed into a science salon, where there are many technographers and craftsmen, all of whom have their own understanding of engineering and technology, except for Queen Victoria and the Chancellor of the Exchequer. They were immediately strongly attracted by the shrunken conversion furnace that Tangning's assistants had carried out. Downing understands very well that to explain a new process clearly, the best thing is for you to make it! It is best to make even the components transparent, so that the engineer can see the core points at a glance, and if the reason is explained thoroughly, then he will not have to study the engineering technology by himself in the future, as long as he can easily be a supervisor.

This small furnace is almost a person high, and the whole process is arranged in an array, almost occupying the center of the entire marble salon, and everyone has to stand aside. Even ordinary people will be full of interest when they see such exquisite and interesting small industrial equipment, and the children brought by the VIPs are even more stunned. Tang Ning reminded: "High-temperature equipment, everyone must pull the children up, don't come here to burn." ”

Tang Ning instructed his assistant to start the steelmaking process while introducing the basic principle: "The steel we use is actually a carbon-iron alloy composed of iron and carbon elements, and the key to making a carbon-iron alloy with suitable hardness and toughness is to control the carbon content. The key to mixing oxygen is to use compressed air, and you can see how the air works wonders. ”

Samuel? Smith didn't feel good in his heart, he was very confident in this kind of steelmaking, and wanted to take a large share of the investment as much as possible, but Downing still made it public to his friends now, and there were not too many rich people present who were willing to invest, so pray that they didn't have a vision......

Under the control of the assistant's wheel, the coal and iron ore are loaded in the trolley, and the conveyor belt is passed to the top of the blast furnace bulging in the middle of the narrow upper and lower parts, and then the raw materials are poured neatly, the children have screamed with joy when they see this interesting scene, and the queen's youngest daughter, the three-year-old Princess Louise, simply slaps the little slap, which is so funny!

Downing didn't know what kind of glass material was used, but it could withstand the 2,000-degree heat, and the audience could clearly see the whole burning process, and the beautiful flame lit their mood - it was so gorgeous. Samuel understands Downing a little bit, and if he makes such an interesting demonstration model, he can't help but play treasure with powerful friends, which is too funny.

As a person who has studied the steelmaking process, Samuel soon discovered a bright spot, the thing that Downing used to light the blast furnace seemed to be very hot, he asked decisively, and Downing smiled: "This is the legendary acetylene, which burns even more spectacularly in pure oxygen." ”

Samuel bowed in, now that acetylene has come out, the welding process is naturally in Downing's planning, which is really an exciting era of big engineering. The production of acetylene is also quite easy, with calcium carbonate (limestone) and coal being the main raw materials for the production of acetylene. First, calcium carbonate is converted to calcium oxide, and coal is converted to coke. Calcium oxide and coke then react to form and carbon monoxide. Calcium carbide plus water will form and calcium hydroxide.

The two pipes at the bottom of the furnace are filled with compressed air, and a small amount of potassium permanganate is injected into the oxidation process.

The beautiful transparent blast furnace, the layering of pig iron, steel, and steel slag can be seen clearly, and it conquered the hearts of science and technology masters at once, and such a demonstration is really flawless.

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

The small blast furnace produced a total of 20 small steel blocks, and Downing said that those interested in investing in his steel mill could take one or two back after cooling to see if they were high-quality steel.

The patent for the steel conversion furnace must be gone, and with so many prestigious elites watching this great engineering invention make its debut, who can deny that our radio genius has invented another big industrial breakthrough technology? What everyone doesn't know is that Downing is tired, these iron ores are phosphorus-free, only Wales and Sweden have such iron ores, and most of the iron ores are phosphorus-containing and need to go through dephosphorization processes, such as adding lime. （http：／／）。 This little secret allowed Downing's technology to be leaked for a long time, and imitators could only get steel of inferior quality due to phosphorus.

The elimination of the iron works and the domination of the rivers and lakes are just around the corner, and this time, the name of the new plant is "British Steel", BS.

Finally started the dinner, in the face of the investment interest of the crowd of inquiries, Tang Ning said that to build the largest steel mill in the United Kingdom, raise 1 million pounds, please everyone first express their investment intentions, with 10,000 pounds as the minimum subscription amount, and finally he will consider the structure of the shares.

In the more than six months since its opening on May 1, the British Telegraph Company has rented out an average of more than a thousand telegraph or typewriters per month, with an estimated annual turnover of up to £1 million, Lionel that 2. The investment of 50,000 pounds has turned into an annual income of 250,000 pounds, and in his eyes, Downing has become a god chicken that can lay golden eggs, so he is quite optimistic about the future of the new company, and directly said, "Do you think I can hold the maximum number of shares?" Samuel expressed a similar sentiment, he has been eyeing this new company for a long time!

Downing regretfully said that he is now not short of funds, and the most important thing is the investor's experience in metallurgy, so Mr. Samuel must be the second largest shareholder, and the share that everyone can invest cannot be too high, Downing personally has to occupy 60% of the shares. This time, he is going to make a lot of money, and the Iron King is close at hand.

The future American steel king Carnegie relies on constantly reducing costs and selling prices to monopolize the market, while Downing, the king, relies on monopoly patents and process kittens, and doesn't care about the cost at all, this is the real king, the king of steel.
