摘　　要：从连铸坯凝固传热数学模型、二次冷却配水与控制、钢的高温力学性能和二次冷却喷嘴冷态及热态特性等方面综述了连铸二次冷却研究的进展,分析了相关研究对优化二次冷却控制和提高铸坯质量的参考作用。对运用经典方法研究特殊钢连铸的二次冷却控制技术具有借鉴作用。The evolution of research on secondary cooling in continuous casting process was reviewed on the basis of mathematical models for the solidification heat transfer in continuous casting process, secondary cooling water distribution and control, high temperature mechanical performance of steel, and cold state and hot state characteristics of nozzles, etc. The effect of some parameters mentioned above upon optimizing secondary cooling comrol and the quality of steel was analyzed. The results obtained are useful to study secondary cooling control technology for continuous casting of special steel using classical methods.
