摘    要：介绍宝山钢铁股份有限公司新建条钢步进式加热炉燃烧控制模型的计算机控制系统。加热炉是保证加热物料的加热质量、节约燃料能耗和确保后继工序物料供给的一个重要生产工序。步进式加热炉一般多应用在热轧生产线,此次宝钢首次在条钢生产线新建大方坯步进式加热炉。文中针对条钢加热炉的特殊工艺要求,着重描述加热炉控制模型中的特殊控制部分,包括:加热制度、热跟踪模型、控制模型细分段控制、待轧控制、结合调度模型预测加热时间及模糊逻辑控制等。宝钢条钢加热炉燃烧控制模型的计算机控制系统稳定运行至今,预测计算和模型控制结果令人满意。

Abstract: Combustion model computer control system for the new built walking beam bar steel reheating furnace in Baoshan Iron and Steel Co.,Ltd.is introduced.Reheating furnace is an important production process to ensure heating quality of heated materials,to save fuel energy consumption and to guarantee material supply of succeeding procedure.Walking beam reheating furnace is usually applied to hot rolling line,but it is built in bar steel production line of Baosteel for the first time.Based on special technological requirement of bar steel reheating furnace,special control parts in reheating furnace control model are described in detail,including heating system,thermal tracking model,fine sectional control of control model,await rolling control,heating time prediction with schedule model,fuzzy logic control,and so on.Combustion model computer control system for reheating furnace of bar steel in Baosteel works stably until now,forecast computation and model control results are satisfactory.
