Using code generated by MATLAB for the Mold Level Control System of a Continuous Slab Caster in ArcelorMittal Gent

The stability of the mold level in continuous slab casting machines is an important factor determining the final quality of flat carbon steel. The existing performant feedback control system of Slab Caster 2 in the Steel Shop of ArcelorMittal Gent will be extended with a feedforward signal using the predicted mold level. A prediction algorithm, an early warning detection system and detailed FFT analysis of the mold level variations have been designed in MATLAB-Simulink. PLC code is generated directly from the MATLAB design, and will be implemented in a PLC serving as PROFINET I-Device in the base automation of slab caster KG2.
