摘　　要：研究了基于酸洗钢增量的轧辊冷却能力提升改造及应用,采用有限元模拟和实物跟踪测量比对模式,对影响轧辊冷却能力的冷却集管及水嘴参数进行综合分析,明确参数在控制轧辊冷却能力方面的调控范围。结果表明,工作辊冷却流量在F2-F4机架提升300 m^(3)/h以上,调整F2-F4入口侧和出口侧的流量比,减少集管中间排的水嘴数量,可满足高拉速大坯厚条件下极薄酸洗钢生产需求,缓解了酸洗钢质量现货率和生产现货率高于内控计划值的问题。In this paper,the improvement and application of roll cooling capacity based on pickling steel increment are studied in detail.The parameters of cooling manifold and water nozle,which affect the cooling ability of roller,are comprehensively analyzed by means of finite element simulation and comparison model.The control range to which these parameters control the cooling capacity of the rolls is found.It is found that the cooling flow of work roll is increased by more than 300 m^(3)/h in F2-F4 frame.By adjusting the flow ratio of F2-F4 inlet side and outlet side and reducing the number of nozzles in the middle of the manifold,these can meet the production demand of extremely thin pickling steel under the condition of high drawing speed and large billet thickness.Also the problem of pickling steel quality spot rate and production spot rate exceeding the internal control plan value is alleviated.
