摘　　要：以环形加热炉在标准产量下满足加热质量要求为前提,以燃耗和氧化烧损最低为目标,通过离线优化研究,得到了标准产量下不同管坯的最优升温曲线。在环形加热炉数学模型优化控制系统中,以管坯最优升温曲线为基础,对炉温进行分段在线寻优,取得了良好的控制效果。The optimal heating-up curves adapted to different types of steel tubes on standard production were obtained in this work in the method of off-line optimization, aimed on the lowest fuel consumption and oxide loss prerequisite heating quality of rotary reheating furnace. The control result of the rotary reheating furnace is proved well in mathematic model optimizing control system, through on-line piecewise furnace temperature optimization based on the optimal heating-up curve of steel tube.
