40-ton converter is an important industrial equipment for steel production. Generally speaking, it is a large-scale high-temperature furnace, which can remove carbon, silicon and other impurities from molten iron, thus obtaining high-purity steel. The "40 tons" of a 40-ton converter is its molten steel capacity, which also shows that the converter is a medium-sized converter. Compared with the larger converter, the 40-ton converter also plays an important role in the steel production process.

40-ton converter is an essential equipment in steel production. In the process of iron and steel smelting, it is necessary to first reduce iron ore into molten iron, which contains many impurity elements, which can not meet the manufacturing needs; Then, after smelting in a 40-ton converter, some impurity elements can be removed, and finally the required alloy products can be obtained. Therefore, the 40-ton converter is directly related to the steel quality and production efficiency of steel mills.

With the improvement of national technical level and the change of market demand, converter steelmaking technology is constantly innovating and developing. The 40-ton converter is also constantly upgraded and optimized, and a new 40-ton converter with more energy saving, environmental protection and high efficiency has emerged. The development trend of 40-ton converter in the future will be more intelligent and automatic, which will make the steel industry realize more efficient and green development.
