摘　　要：韶钢特轧厂第一棒材工序加热炉投产时间较长,由于余热回收不完善,排烟温度较高,造成余热资源浪费。通过节能技术改造,增加余热锅炉设施将烟气余热回收,增设蒸发器,代替原来冷却风机降温保护空气预热器的方式,取得了较好的节能效果。The reheating furnace for the bar rolling mill at SGIS was put into operation for a long time,and the waste of waste heat resources was caused by the imperfect recovery of waste heat and the high exhaust temperature.Through the technical transformation of energy saving,the bypass flue was added to the original flue,the waste heat boiler was set up to recover the waste heat of the flue gas,and the evaporator was added in front of the original air preheater to replace the way of cooling by the original cooling fan to protect the air preheater.The transformation has achieved the expected goal and achieved good energy saving effect.
