摘　　要：根据建立的在线温度推算模型和冷却段表面温度预测模型,设计了一种板坯连铸二冷段动态配水模型,实现铸坯表面温度自适应控制。该模型通过利用在线调整神经网络配水模型权重,使板坯表面温度与目标温度的差值最小化。现场数据分析证明了模型的适用性,仿真结果表明,模型对表面温度控制的效果优于在线温度推算模型。Based on on-line temperature calculation model and surface temperature prediction model for cooling section, an dynamic water distribution model was designed to realize the adaptive control for cast surface temperature. In this method, weight of neural network water distribution model was adjusted to minimize deviation between cast surface temperature and object temperature. Field data analysis proves suitability of the model. Simulation results show that surface temperature control effect of the model is better than control effect of temperature calculation model.
