针对济南钢铁集团总公司热连轧厂原有层流冷却系统存在的冷却效果差、卷取温度不可控等问题,分析原因进行了有针对性的改进,从而取得了很好的冷却效果。温度控制是热轧生产线控制的重点,而层流冷却控制(CTC)则是温度控制的关键环节,CTC命中率的好坏直接关系到带钢的质量和成材率。济南钢铁集团总公司热连轧厂(以下简称济钢热连轧厂)原CTC系统由于温度控制准确度不够、冷却模式固定等原因直接带来了带钢性能无法保证、新产品
In view of the existing cooling effects of the existing laminar cooling system in the hot rolling mill of Jinan Iron and Steel Group Corporation are poor, the coiling temperature is not controllable and other issues, the analysis of the reasons for the targeted improvements, and achieved good cooling effect. Temperature control is the key point of hot rolling production line control, while laminar flow cooling control (CTC) is the key part of temperature control. The quality of CTC hit rate is directly related to the quality and yield of strip steel. Jinan Iron and Steel Group Corporation hot rolling plant (hereinafter referred to as the Jinan Iron and Steel rolling plant) the original CTC system temperature control accuracy is not enough, the cooling mode is fixed and other reasons directly brought the strip performance can not be guaranteed, the new product
