Technical Data

The iEAF® technology for the DRI furnace is used to continuously monitor gas-phase, energy, and bath/slag properties and provide real-time control of EAF operation by dynamic adjustment to process parameters.  The objective is to implement closed-loop control of:

Oxygen injection

Carbon injection

DRI feed rate, based on material characteristics (metallization, composition)

Electrical Power

Lime injection

Flux addition prediction based on material characteristics and real time information.

Fume System Operation
