Intelligent Ironmaking Optimization Service on a Cloud Computing Platform by Digital Twin Article

Heng Zhou, Chunjie Yang, Youxian Sun

Engineering 2021, Volume 7, Issue 9, Pages 1274-1281 doi: 10.1016/j.eng.2021.04.022

Abstract:

The shortage of computation methods and storage devices has largely limited the development of multiobjective optimization in industrial processes. To improve the operational levels of the process industries, we propose a multi-objective optimization framework based on cloud services and a cloud distribution system. Real-time data from manufacturing procedures are first temporarily stored in a local database, and then transferred to the relational database in the cloud. Next, a distribution system with elastic compute power is set up for the optimization framework. Finally, a multi-objective optimization model based on deep learning and an evolutionary algorithm is proposed to optimize several conflicting goals of the blast furnace ironmaking process. With the application of this optimization service in a cloud factory, iron production was found to increase by 83.91 t∙d^-1, the coke ratio decreased 13.50 kg∙t^-1, and the silicon content decreased by an average of 0.047%.

Frontiers of Mechanical Engineering 2007, Volume 2, Issue 2, Pages 224-227 doi: 10.1007/s11465-007-0039-1

Abstract: The high-speed double wire pulse metal gas arc (MAG) welding process possesses advantages of automation and high efficiency and quality. Thus, it attracts much more attention nowadays. To meet the requirements of the double wire pulse MAG welding process, a novel double wire pulse MAG welding inverter integrated with technologies, such as soft-switching, double closed loop control, and synchronic control, is produced. A complete performance test was done for the pulsed MAG welding power supply by using a computer testing platform. The results of the experiment indicate that the novel welding inverter has an excellent performance both in the dynamic and the static characteristics. Also, the synchronic control between the master inverter and the slave inverter is reliable.
