Kobe Steel Ltd. started up a new hot-metal treatment plant at its Kakogawa Works in western Japan. The company previously announced that it would construct the facility to improve the production system at Kakogawa. Hot-metal treatment is a process to remove impurities (sulfur and phosphorus) in molten iron. Kobe Steel’s hot-metal treatment plant increases the reaction efficiency during desulfurization and dephosphorization, thereby reducing the consumption of auxiliary materials for refining and improving yield. The facility includes two reactors for desulfurization and one dephosphorization furnace.
