Design of an optimization and control system for carbon efficiency in the green manufacturing of sinter ore

Sinter ore is the raw material of the iron and steel production. A sintering production process is with high energy consumption and large CO₂ emissions. It is important to achieve the green manufacturing of the sinter ore. In this paper, an optimization and control system for the carbon efficiency (OCSCE) in the green manufacturing of the sinter ore is designed from the point of view of the maximum utilization of the carbon and the best protection of environment in the sintering process. The OCSCE has three parts: the optimization for the carbon efficiency, the coordinated optimization and control for the production phases and the comprehensive performance evaluation for the carbon efficiency. The optimization for the carbon efficiency is used to optimize the state parameters. The coordinated optimization and control for the production phases is applied to optimize and control the operation parameters. The comprehensive performance evaluation for the carbon efficiency assesses whether the carbon efficiency of the whole sintering process is consistent with green manufacturing. Finally, an implementation scheme of the OCSCE is put forward for the industrial site. The results of preliminary tests show that the OCSCE is in line with the needs of the industrial site, and it will have a significant performance after the OCSCE is put into the industrial site.
