Japanese iron and steel smelting technology is recognized as the leading position in the world. Japan's steel technology, including steelmaking technology, is world-leading, even surpassing developed countries in Europe and America. On the other hand, Japan's leading position is reflected in the patent field. It can be said that there is hardly a blast furnace or steel mill in the world that is not built with a Japanese license.
As a country that does not produce iron ore locally, the output and quality of steel are world-leading, which is very admirable.
Japan's metallurgical technology has reached the world-class level. Especially in the key technical fields such as bottom blowing technology, slag splashing and furnace refining, Japan not only has corresponding technical patents, but also applies them to industrial production in an all-round way, injecting a shot in the arm for the re-emergence of iron and steel industry.
Japan maintains a number of records in the steel industry:
For example, JSW factory in Japan has become the only factory in the world that can produce pressure vessels for nuclear power plants, accounting for 80% of the global market; Although Kobe Steel is only the third largest steel enterprise in Japan, it ranks among the top 500 enterprises in the world.
The steel produced by Kobe Steel is widely used in many industrial fields such as machinery and engineering, and even some developed countries in Europe and America have to import from Japan. What makes the Japanese proud is that the most authoritative iron and steel metallurgical magazine ISIJ is also in Japan.
