金属材料与冶金工程第51卷第1期拉矫机内吹扫流场分析及优化张宦修1，李丹1，彭兴东2*（1.上海梅山钢铁股份有限公司，江苏南京210039；2.辽宁科技大学材料与冶金学院，辽宁鞍山114051）摘要：采用ANSYS软件对拉矫机内吹扫流场进行了分析。结果表明：优化前吹扫梁上8个喷嘴间距为19cm，喷嘴长度为6.7cm，空气喷嘴与竖直方向成45°，喷嘴之间的空气吹扫流场相互干扰，带钢上出现氧化铁皮颗粒滞留区。优化后吹扫梁上9个喷嘴间距为16.625cm，中间1个喷嘴长度为8.7cm，其它喷嘴长度均为6.7cm，喷嘴与竖直方向成45°，且左侧4个喷嘴沿垂直吹扫梁方向右偏10°，右侧4个喷嘴沿垂直吹扫梁方向左偏10°，空气喷嘴之间的吹扫流场干扰有明显改善，带钢上没有出现氧化铁皮颗粒滞留区。拉矫机内吹扫流场优化后，酸洗板面凹坑月平均缺陷率为0.43%，比流场优化前降低了2.98%。关键词：凹坑缺陷；拉矫机；吹扫流场中图分类号：TG333.2+3文献标识码：A文章编号：2095-5014（2023）01-0044-06AnalysisandOptimizationofPurgeFlowFieldinTensionLevelerZHANGHuanxiu1，LIDan1，PENGXingdong2（1.ColdRolledStripSteelPlant，ShanghaiMeishanIronandSteelCo.，Ltd.，Nanjing210039，China；2.SchoolofMaterialsandMetallurgy，UniversityofScienceandTechnologyLiaoning，Anshan114051，China）ABSTRACT：ThepurgeflowfieldinthetensionlevelerwasanalyzedbyANSYSsoftware.Beforeoptimization，thedistancebetween8nozzlesonthepurgingbeamis19cm，thenozzlelengthis6.7cm，theairnozzleis45°totheverticaldirection，andthenozzlelengthis6.7cm.Sotheairpurgingflowfieldbetweenthenozzlesinterfereswitheachother，andtheironoxidescaleparticleretentionzoneappearedonthestripsteel.Afteroptimization，thedistancebetweentheninenozzlesonthepurgingbeamis16.625cm，thelengthofthemiddlenozzleis8.7cm，andthelengthoftheothernozzlesis6.7cm.Thenozzleis45°fromtheverticaldirection，andthefournozzlesontheleftsideare10°totherightalongthedirectionoftheverticalpurgingbeam，andthefournozzlesontherightsideare10°totheleftalongthedirectionoftheverticalpurgingbeam.Theinterferenceofthepurgingflowfieldbetweentheairnozzleshasbeensignificantlyimproved，andthereisnoironoxidescaleparticleretentionareaonthestripsteel.Alsothemonthlyaveragede...
