JFE has manufacturing equipment in its west Japan base in Kurashiki and its
east Japan base in Sendai, allowing our customers to choose from blast
furnace and electric arc furnace materials according to their needs.
High-cleanliness steel with the blast
furnace-converter method (Kurashiki)
The combination of the blast furnace, hot-metal pretreatment, top and bottom
blown converter, ladle refining, and strongly-stirred vacuum degassing
processes has enabled the production of high-cleanliness steel.
