The new constant courant electrical arc furnace (C.C. E.A.F.) at Cockerill Sambre Marcinelle–Charleroi (BE) uses an anode that dips into scrap metal to melt it while the furnace bottom acts as the cathode to pass current, and it is equipped with coal injection lances, burners, and an automatic scrap loading system with fumes recovery. The furnace automation system was the first project to program both sequential and analog control into the same redundant programmable control unit using the INFI-90 system from Bailey.

- 1. New C.C. E.A.F. (Constant Courant Electrical Arc Furnace) at Cockerill Sambre Marcinelle – Charleroi (BE): The new EAF from Paul Wirth consists of an anode (positive pole) which dips into the scrap to melt it. The bottom of the oven acts as a cathode (negative pole) to pass current. The EAF is equipped with coal injection lances, burners, automatic loading of scrap and a fumes recovery system.

- 4. The New Automation System for the C.C. E.A.F. is completely made with the INFI-90 System from Bailey: It was the first project where PLC was not more used and both sequential and analog control (PID controller) was programmed into the same redundant PCU. The PCU was formated into differents parts to have differents time scanning based on analog, ladder or grafcet control. INFI-90 ARCHITECTURE: (OIS) (Informatic Level)
