Q-MELT® Automatic EAF at Kroman Çelik

Reduced process variability, increased productivity and lower OPEX will be achieved by applying automatically the Best Operating Practices to dynamic process conditions

Q-Melt Automatic EAF

Kroman Çelik is one of the largest steel producers in Turkey and is well known all over the world for its outstanding meltshop performances.

In order to enhance EAF competitiveness and performance, Kroman has awarded Danieli an order for a state-of-the-art Q-Melt® Automatic EAF technology, as well as an upgrade of the Chemical Injection System.
Kroman’s EAF will be fitted with the Q-Melt® Dynamic Heat Suite, the module of the Q-Melt® Automatic EAF dedicated to the metallurgical control of the EAF process, which includes:

-Q-REG Plus dynamic electrode regulator with arc coverage control;
-LINDARC in situ gas analyzer with TDLAS laser spectrometer;
-MELT-MODEL process control & optimizer.

The core of the Dynamic Heat Suite is the MELT-MODEL. It interacts with the Q-REG Plus electrode regulator and the LINDARC gas analyzer to continuously control operating conditions by processing chemical and/or electrical profiles to dynamically (and automatically) make the necessary adjustments to the EAF process, always at the best possible practice.
The Melt Model creates optimized furnace profiles using all the main process variables, including charged material properties and slag conditions.
