结合本钢2300机组生产线,通过控制和优化加热制度、压下制度和料流跟踪等手段,使近80%因粗轧机组卡钢事故产生的废板坯进行了重新回炉加热和再轧制,而且,轧成的成品钢卷尺寸精度和各项性能指标均符合工艺要求,有效地降低了热轧机组的过程废品数量,并减轻了重新炼钢、坯料库存、物流循环等一系列问题所带来的压力,达到了提高成材率和降本增效的目的。 Combining with the production line of Benxi Iron and Steel Group 2300, nearly 80% of the scrap slabs generated from the steel-card accident in the roughing unit were reheated and rolled again through the control and optimization of the heating system, reduction system and flow tracking. Moreover, the finished coil rolled into the dimensional accuracy and performance indicators are in line with process requirements, effectively reducing the number of process waste hot-rolled unit, and reduce the re-steel, billet inventory, logistics and recycling and a series of problems The pressure to achieve the purpose of improving the yield and reducing costs and increasing efficiency.
