宽厚板辊底式常化炉热处理优化控制研究

Optimal Control Process for Wide and Heavy Plate Reheating Furnace Based on Normalizing Treatment

以某钢厂辊底式常化炉为研究对象,在详细分析其传热机理的基础上,建立了钢板各点在炉内运动的温度变化数学模型;并以该模型预测的钢温为依据,按照工艺要求动态实时修正炉温和钢板的运行速度。针对炉型紧凑、工艺复杂和不同规格钢板混装现象的情况,系统可以有效地模拟钢板在炉内加热升温的全过程,并对炉每块钢板的各自速度和总体炉区温度进行寻优计算。结果表明,该系统提高了生产线的自动化程度和生产效率,能有效保证钢板产品的材料组织性能。

Normalizing treatment process,wide and heavy Plate,roller hearth normalizing furnace;mathematical model for metallurgical process a mathematical model of wide and heavy plate reheating process for roller hearth normalizing furnace is proposed.Based on the model,the optimal control strategy of reheating process is performed such that the automation and efficient of production is promoted.
