Market leading Korean steelmaker SeAH Besteel, believed to be the largest special steel producer in the country, with a total production capacity of 3.1Mt/yr is planning to upgrade one of its four electric arc furnaces (EAFs).

EAF#3 is to be fitted with Danieli Q-Melt technology.

According to Danieli, Q-Melt is the latest evolution of its automatic control concept for the EAF melting process.

The suite of Q-Melt products comprises Q-Reg Plus dynamic electrode regulator with arc coverage control and slag foaming detection; Lindarc in-situ gas analyser with TDLAS laser spectrometer; and Melt-Model process control and optimiser.

The core of the system is the Melt-Model that automatically identifies deviations in process-controlled variables and corrects them according to the best possible practice, to avoid losses or wasting of available energy sources.

This will be Danieli’s first Q-Melt in Korea. Installation is expected by September 2018.

Danieli and SeAH Besteel have an established relationship going back 30 years.
