提高高强钢连退成材率的研究与实践

Research and Practice on Increasing the Yield of High Strength Steel by Continuous Annealing

河钢集团邯郸钢铁有限公司邯宝冷轧厂生产的高强钢冷轧薄板广泛用于对安全性与轻量化要求较高的汽车工业、家电行业等领域。针对其连退生产线成材率较低的问题,工厂开展了以提高产品成材率为目标的质量攻关。通过前期生产数据的统计,对造成高强钢连退生产线成材率不高的原因进行分析,有的放矢地采取措施,把阶段性的实践成果提炼出来,并将其标准化为《高强连退线岗位操作规程》,为设备的全面达质、达产、达效奠定了基础。

The cold-rolled sheet of high-strength steel produced by Hanbao Cold Rolling Plant of Handan Iron and Steel Co.,Ltd.of Hegang Group is widely used in automotive industry,household appliances industry and other fields with high requirements for safety and lightweight.In view of the low yield of continuous annealing production line,the factory has carried out quality research aimed at improving the yield of products.Based on the statistics of production data in the early stage,this paper analyzes the reasons for the low yield of high-strength steel continuous annealing production line,takes targeted measures,distills the phased practical achievements,and standardizes them into the operating procedures for high strength continuous annealing line post,laying a foundation for the overall quality,production and efficiency of the equipment.
