| Abstract: | The prediction of the surface crack of the continuous casting steel was carried out by monitoring the mold temperature and the friction between mold and strand. The mathematical model of crack prediction and the crack criterion based on strain-stress and the difference of strain energy producing crack were introduced. The development trend of predicting crack was presented. |
