Abstract: For steel refining process some of parameters are very critical and can induce to a loss of production by the need of additional corrections in the shape of reblowing. Among these parameters: carbon and manganese contents, temperature of the final product. In order to monitor such a system, we propose a multi neural network based fault detection and diagnosis scheme. A serial/parallel homogeneous configuration is adopted as the basic structure of the detection system. The first stage allows the classification of the sample according to the nature of the steel nuance to be produced while the second stage of the network allows the identification of the volume of oxygen necessary to fusion and will be used as an input for the last stage witch detect and diagnoses the faults. The simulation results illustrated that after training of the neural networks, the system is successfully detects and diagnoses the different failures.
