| Abstract: | The real-time molten steel temperature is measured by blackbody cavity continuous temperature measuring system for liquid steel in CC Tundish.Based on it,a heat transfer equation and dynamic water distribution control model are established for the secondary water cooling in continuous slab casting.The relationship of water flow,casting speed and superheat is obtained.Furthermore,a secondary cooling control system is designed.Field application proves the suitability of models,and shows that the proposed cont... |
