In the blazing flames of 1600, the converter is not a container, but a time-space tunnel where molten iron undergoes a metamorphosis. In 21 minutes, a batch of ordinary molten iron is transformed into robust steel that powers aircraft carriers, propels high-speed rail, and shapes the urban skyline. We make every oxygen lance whistle become a trumpet call for the advancement of the times; we let every furnace pouring mark a milestone in the development of national strategic assets. Choosing the converter means choosing to forge fire and will into the backbone of the world.
