摘　　要：为了快速有效地降低加热炉能耗,针对莱钢厚板生产线能源消耗大户加热炉的燃料消耗影响因素进行分析,结合现场实际情况实施技术改造。装钢时序优化提高了装钢节奏,拓展热送热装坯型结构增加了板坯单重、提高了热送热装率;通过加热工艺优化、停轧降温制度、炉体节能技术等方面的措施,延长了加热炉维修周期和使用寿命。莱钢厚板线年产能提高到172.3万t,煤耗指标降低到1.424 GJ/t,达到了提高产能、降低能耗的预期效果。In order to reduce the energy consumption of reheating furnace rapidly and effectively,the factors influencing the fuel consumption of the reheating furnace,the heavy energy consumer in Laigang heavy plate production line,are analyzed,the technical revamp is performed on the basis of the actual condition at site.The charging sequence optimization improves the charging pace,the single piece weight and the hot charging rate are increased by expanding hot charging and hot delivering slab type structure,the maintenance cycle and service life of the reheating furnace are extended by the corresponding measures of reheating process optimization,the temperature decreasing mechanism at rolling interruptions and furnace body energy conservation.The annual production capacity of Laigang heavy plate production line is increased to 1.723 million tons,and the coal consumption index is reduced to 1.424 GJ/t,which has achieved the expected result of improving production capacity and reducing energy consumption.
