Advanced On-line Expert System for Continuous Casting
CC-EYE

ANN(Artificial Neural Network) based Smart Factory System for Continuous Casting

On-line Prediction of Qualities and Origins of Defects
CC-EYE offers a function of advanced on-line monitoring of quality related parameters, cracks, and central
segregation during continuous casting. It may predict surface crack very accurately using the feature parameters
from the system and artificial neural network. It also gives on-line prediction of the origins of defects and casting
abnormalities, and it is easy to check whether these problems are solved. Eventually, the basic framework for
Smart Factory System for continuous casting can be constructed.
