摘　　要：为了目标轧件拥有优良的内部组织结构,获得好的强韧性能,采用对带钢热连轧温度制度进行在线控制。引入自学习功能,通过对热对流散热系数进行修正和层流冷却段温度累积求和,机理模型更适用于生产实际。In order to obtain excellent internal structure and good strength and toughness, the temperature system of hot strip continuous rolling is controlled on line. By introducing the self-learning function, the mechanism model is more suitable for production practice by modifying the thermal convection heat dissipation coefficient and accumulating and summing the temperature of laminar cooling section.
