EAF Electric arc furnace process control

For EAF process control powerful process models are provided, allowing any kind of raw material charge mix, such as a combinations of scrap, hot or cold DRI/HBI, pig iron and hot metal.

Operational set points are generated in real-time for various melting practices, such as:

	Batch charging.
	Continuous feeding.
	Combined batch and continuous feeding.

Main modules involved:

	LCC Least-cost Charge Calculator, to optimize the charges to be used.
	Static Mass & Heat Balance for the pre-calculation of the required   amounts of raw materials and energy for melting.
	Process Cycle Set Up for the pre-calculation of operational set points.
	Set Point Generation for on-line control of electrical power input, oxygen, fuel, carbon, and charge materials flowrate.
	Dynamic Set Point Generation, which uses the harmonic analysis of the electric arc, and the online analysis of the offgas as feedback for the calculation.
	Tapping additions calculations for deoxidization, slag-forming and alloying, including Jominy and DI calculations.
