英文摘要：

To automatically obtain the real-time data of steel continuous casting plant accurately and provide better MRO（Maintenance,Repair and Overhaul） services,a framework for Internet of Things（IoT） oriented to continuous casting MRO was established.Application scenarios of IoT in steel industry based on MRO were provided.It not only provided new data sources for steel enterprises,but also improved the production and business process.Hierarchical architecture of the proposed framework and its key technologies were described in detail,which indicated that IoT technology was critical to realize the service of MRO.Implementation of IoT in MRO was also analyzed in particular.Applications showed the effectiveness of this framework.
