2050 2050 宝轧精准选样系统 苏 异 才 （上海宝钢研究院 自动化所，上海 201900） 摘要：针对热轧带钢传统采样方法存在的取样量大和漏检等主要问题，新的精准选样系统设 计了一种精细化的采样管理方法，将采样管理过程与热轧产品生产过程联系起来，利用先进 的热轧带钢力学性能预报模型的预报结果，对带钢进行分类后用于指导采样。该系统已于2008 年成功应用于宝山钢铁股份有限公司2050热轧厂，实现了热轧带钢采样的精准选样管理，应 用效果良好，在减少取样量和加快物流等方面效果明显。 关键词：热轧带钢；精准选样；机械性能；性能预报模型；数据仓库 B B 中图分类号： 文献标志码：BB 文章编号：1000-7059（2012）06-00 -0 Precisesamplingsystemin2050hotrollingmillofBaosteel Precisesamplingsystemin2050hotrollingmillofBaosteel PPrreecciisseessaammpplliinnggssyysstteemmiinhoottrroolllliinnggmmiillllooffBBaaoosstteeeell SUYi-cai (AutomationDepartment,ShanghaiBaosteelResearch Institute,Shanghai201900,China) Abstract: Abstract: AAbbssttrraacctt:: The traditional sampling method of hot strip has some major problem, such as sampling volume and missed case. The new precise sampling system has designed a precise and fine sampling method, which will contact the sampling management flow with the whole produce process of hot strip.At the same time, the system classifies the strips and guides the sampling with the result of mechanical properties predict model for them. It has made a successful application in Baosteel 2050 hot rolling mill in 2008 and realizes the sampling precision sampling management. Application results show that the new sampling method can obviously reduce sample volume of hot stripsandspeed uplogistics, whichdemonstratesitsapplicationvalue.
