Chapter 476 Electric Arc Furnace
Chapter 476 Electric Arc Furnace
Shenzhen.
Inside a certain manor.
In the study room, Xiao Jun was sitting on the desk reading a book.
There is a thick stack of various books and materials on the table.
"Basic Knowledge of Electric Arc Furnace", "Core Materials of Electric Arc Furnace of Ares Company", "Encyclopedia of Design Data of Five-phase Electric Arc Furnace of Ares Company", "Theory of Future Development Direction of Electric Arc Furnace", "Encyclopedia of Electric Arc Furnace Technology of Antai Iron and Steel Company"...
On the desk, there are basically books and materials related to electric arc furnaces.
All of the information is provided by Saiboda Xueshen and Takishima Comet. As for the rest of the data, it is some books collected by Xiao Jun in his world.
Of course, the books on electric arc furnace technology collected by the earth are basically basic knowledge, which are only for understanding, without any advanced technical content.
The real electric arc furnace technology is either in the hands of those steel companies or in the hands of those R&D companies.
The reason why Xiao Jun reads these books is mainly to have an in-depth understanding of the earth's electric arc furnace technology.
What he really wants to learn is the electric arc furnace technology he got from Saiboda and Takishima Comet!
That's right, since he is determined to vigorously develop the steel industry, he must have his own core technology.
In the past, the core technology of steel was the blast furnace!
The furnace is made of steel plate, and the shell is lined with refractory bricks. From top to bottom, the blast furnace body is divided into five parts: the furnace throat, the furnace body, the furnace waist, the furnace bosh, and the hearth. Due to the good technical and economic indicators of blast furnace ironmaking, simple process, large production volume, high labor production efficiency, and low energy consumption, the iron produced by this method accounts for the vast majority of the world's total iron production.
However, with the development of the times, the human industry has an increasing demand for high-quality steel, and the quality of steel produced by blast furnaces is indeed not satisfactory.
So then there was the advent of the electric arc furnace!
Now, most of the high-quality steel products are produced by electric arc furnaces.
An electric arc furnace uses the high temperature generated by the electrode arc to smelt ores and metals. When the gas discharge forms an arc, the energy is very concentrated, and the temperature in the arc area is above 3000°C to 4000°C. For smelting metals, the electric arc furnace is more flexible than other steelmaking furnaces. It can effectively remove impurities such as sulfur and phosphorus. The furnace temperature is easy to control and the equipment occupies a small area. It is suitable for smelting high-quality alloy steel.
And Xiao Jun's own steel company is definitely taking the high-quality steel route, not the low-end just now route. So he does not plan to build blast furnaces, but builds electric arc furnaces uniformly.
First of all, blast furnaces are polluting a lot now, which is not suitable for the development of the times.
On the contrary, electric arc furnaces use electricity. How much is the electricity bill now? With the launch of the Galaxy Reactor of the Galaxy Group, China's electricity bills are now very cheap, which has led to greater profits for the entire Huaxia industry.
If all steel companies use electric arc furnaces in the future, the profit will be greater and the cost will be lower!
Of course, at present, most of them are blast furnaces, followed by electric arc furnaces. Take Huaxia as an example, steel companies still have more blast furnaces, why? First of all, Huaxia's original electricity did not allow it. Not enough!
Electric arc furnaces are very power hungry.
This is also the same in other countries. Industrial electricity is expensive, and the cost is even higher.
But it is different now. With the advent of the Galaxy Reactor, a reactor can produce 80 billion kilowatt-hours of electricity a year. Huaxia built ten before, and will build more than ten more in the next three years!
Now most of China's steel companies are planning to build more electric arc furnaces.
Because electricity is cheap.
Moreover, the steel produced by the electric arc furnace is much higher quality than the blast furnace, which is more in line with the future development trend.
Due to the high thermal efficiency of the large-capacity electric arc furnace, the power consumption per ton of steel can be reduced. At the same time, the average equipment investment per ton of steel is also greatly reduced, the cost of steel is reduced, and labor productivity is increased. For example, compared with a small furnace with a capacity of 320 tons and a small furnace with a capacity of 1.5 tons, the productivity difference is more than 100 times. In some special cases, when a large amount of high-quality molten steel is required, only large-capacity electric arc furnaces can meet the requirements. Therefore, many countries in the world use large-capacity electric arc furnaces. There are more than 30 electric arc furnaces with a capacity of more than 80 tons, the largest of which is 400 tons. Huaxia Electric Arc Furnace has a maximum capacity of 150 tons. There is still a big gap with the international.
In the 1970s and 1980s, some industrially developed countries developed DC steelmaking electric arc furnaces one after another, and achieved remarkable progress. Island countries started late in the development of DC electric arc furnaces, but developed the fastest, and are currently the countries with the largest number of DC electric arc furnaces in use. A single large-capacity electric arc furnace is the development trend of the steelmaking industry in recent years, which can meet the needs of steel mills for higher productivity. In recent years, due to the development and application of high-power thyristor technology, DC electric arc furnace has attracted people's attention again due to its advantages.
It is said that the most powerful electric arc furnace at present is the world's largest 420-ton DC electric arc furnace, 420-ton ladle refining furnace and double vacuum degassing system successfully manufactured in Italy a few years ago. The electric furnace is used to produce low carbon steel, ultra low carbon steel and advanced deoxidized killed steel with an annual output of 2.6 million tons.
So Xiao Jun will definitely choose the electric arc furnace instead of the traditional steel blast furnace!
Now Xiao Jun is researching "Aris Company's Electric Arc Furnace Core Data" and "Aris Company's Five-Phase Electric Arc Furnace Design Data Collection" these days. These two pieces of information were obtained from Saiboda.
Originally, the world Saiboda lived in had a technological level several times higher than Xiao Jun's.
Especially in the area of steel technology.
For example, Skynet developed liquid steel, steel that can be liquefied.
Awesome.
This liquid steel has gone beyond the definition of steel. A robot can be liquefied, which proves that in addition to just now, the steel in it also includes circuits, chips, weapons, electronic systems, etc. integrated into it.
It can belong to a super epoch-making new material!
This new material is a fusion of alloys, chip materials, electronic materials, weapons, etc. All parts in the above fields can be designed and used on this liquid steel!
That is to say, this liquid steel can be used as graphene, silicon crystal, plastic, alloy, circuit, explosive...etc!
For example, a robot needs materials such as alloys, circuit materials, chip materials, weapon materials, explosives, new materials, and so on. However, there is only one material for all liquid robots, and that is liquefied steel. The same material can produce parts in various fields, which is terrifying!
However, this liquid steel technology is currently being sorted out by Saiboda, and he very much hopes to obtain the core technology of this material.
After all, this was not invented by Saiboda, but by Skynet. I have to say that Skynet is too evil.
