依托基于先进检测与智能装备支撑的少人/无人化操维集控,以及基于工业互联网平台的多业务协同数字化业务管控,形成了“双智控”的轧钢智能工厂建设架构。然而,在研究与应用领域,对于智能装备的概念,并没有建立起清晰明确的定位认识。结合具体的技术模块描述与案例介绍,探讨了智能装备对智能工厂的作用效果与价值体现。首先,通过依托全流程表面检测的表面质量数字化管控、融合“平台+装备+视频AI+跟踪”的物料逐支跟踪、原料库与加热炉区域坯料检测与异常识别校核、智能化视觉检测装备辅助运维管理等案例,提出了先进检测增强感知支撑数字化业务管控的智能装备建设模式;其次,通过介绍多类工业机器人应用、热轧运行非对称检测与自动纠偏控制、中厚板轧机自动转钢、加热炉智能改造和直接轧制技术,展示了建设主生产流程设备控制系统协同的“测控一体化智能装备”,提升产品质量稳定性与生产自动化水平的发展趋势;还有,介绍了长材平面智能无人库技术、棒材轧后区域少人化技术,提出了针对缺乏自动控制、人工操作密集且工作环境恶劣的区域,通过多类型智能装备应用,实现生产效率、成材率等关键运行指标提升的发展模式。最后,展望了智能装备的发展趋势,即与主生产设备、关键质量控制更加紧密融合,实现面向高效化、高质化生产的“智能轧机”,并支撑数字化业务管控应用的完善,推动双智控“智能钢厂”建设水平的持续提升。

Relying on the less manned/unmanned operation and maintenance centralized control based on advanced inspection and intelligent equipment support,as well as multi-business collaborative digital business control based on the industrial Internet platform,it has formed a“dual intelligent control”structure for the construction of steel rolling intelligent factory.However,in the field of research and application,the concept of intelligent equipment has not yet established a clear and explicit positioning understanding.The description of specific technology modules and case studies are combined to discuss the effect and value of intelligent equipment on intelligent factories.Firstly,by relying on the whole process of surface inspection of surface quality digital control,integration of“platform+equipment+video AI+tracking”material tracking by branch,raw material warehouse and heating furnace area billet inspection and anomaly identification verification,intelligent visual inspection equipment to assist in operation and maintenance management,etc.,an intelligent equipment construction model based on advanced inspection with enhanced perception to support digital business management and control is proposed.Secondly,by introducing the application of multiple types of industrial robots,asymmetric inspection and automatic deviation correction control in hot rolling operation,automatic steel transfer in medium plate mill,and intelligent transformation of heating furnace and direct rolling technology,the construction of“intelligent equipment for measurement and control integration”in collaboration with the control system of the equipment of the main production process and the development trend of improving the stability of product quality and the level of automation of production are demonstrated.Thirdly,it introduces the intelligent unmanned warehouse technology for long products and the less manned technology for bars in the post-rolling area,which puts forward the development mode of realizing the enhancement of key operation indexes such as production efficiency and product yield through the application of multiple types of intelligent equipments for the areas that are lack of automation control,intensive manual operation and harsh working environment.Finally,it looks forward to the development trend of intelligent equipment,that is,to integrate more closely with the main production equipment and key quality control,to realize the“intelligent mill”oriented to efficient and high-quality production,and to support the improvement of the digital business management and control applications,and to promote the continuous improvement of the construction level of the dual-intelligent control“intelligent steel mill”.
