| Abstract: | The effects of superheat, casting speed, secondary cooling water flowrate, M-EMS on porosity of billets were investigated. The tests of extra cooling during solidification of the final potion of strand were carried out for the decrease of the centerline segregation. The grades of porosity were predicted by means of the artificial neural network. |
