Iron is melted in the DUPLEX system. Metal is melted in the long campaign liningless cupola with heated blow, equipped with an oxygen injection system and a dry system for flue gas dedusting. The precise metal parameters (chemical composition, temperature) are obtained in two FS crucible induction furnaces operating in the TWIN-POWER system, from ABP Germany. Cast iron spheroidising treatment is a very effective and repeatable method for production of flexible cable.
