摘　　要：氧化烧损是金属热加工中影响经济技术指标的重要因素。轧钢加热炉在加热过程中钢的氧化烧损会造成一定的经济损失,同时氧化铁皮还会降低成品表面质量,延长钢在炉加热时间,增加停炉清渣次数等。通过分析、讨论影响板坯氧化烧损的因素,提出了降低板坯出炉目标温度、减少板坯在炉时间、合理控制炉内气氛等优化措施,板坯氧化烧损得到有效控制,创造了良好的经济效益和社会效益。Oxidation burning loss is an important factor to affect economic and technical indexes in metal hot-working.Steel oxidation burning loss in heating furnace would make a certain economical loss,the scale would affect the surface quality of products,prolong the heating time and increase times of stopping and slag-clearing.Based on analysis and discussion about the factors to affect slab oxidation burning loss,it is proposed the measures to effectively control the loss： lowering furnace exit temperature of slab,shortening heating time,and reasonably controlling furnace atmosphere,excellent economic and social profit got.
