减少板坯氧化烧损的措施

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。

MEASURES TO REDUCE OXIDATION BURNING LOSS OF SLAB

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.
