CIE Wins First Prize at the Inaugural High-Value Patent Competition of Six Central Provinces

2024/04/23

On April 22, the Hubei sub-venue event for the 2024 National Intellectual Property Publicity Week opening ceremony was held in Wuhan. During the event, awards were presented to 30 projects that won the first prize in the "Inaugural High-Value Patent Competition of Six Central Provinces." CIE's patent for the "Homogeneous Sintering Method Based on Layered Composite Heating" received this prestigious honor.

 

 

This patent builds upon the traditional iron ore sintering model. It establishes a refined layered heating process system that features surface reheating through ignition after overall carbon reduction, upper layer reheating through insulation, middle layer reheating through hydrogen-rich gas injection, and enhanced fuel combustion through steam coupling injection. CIE creates a gas-solid two-phase composite layered heating sintering technology based on baseline carbon coordination and the coupling of multiple media in terms of quality, quantity, time, and space. It overcomes the long-standing technical bottlenecks in the sintering process, such as low heat utilization, incomplete combustion, high carbon emissions from solid fuels, and poor control of condensation and mineralization, which have led to high carbon and pollutant emissions in the sintering process. This patent offers an innovative solution for low-carbon, clean, and high-quality production in the sintering process of the steel industry.

 

 

 

Since its implementation in 2020, this patented technology has been promoted and applied in the sintering projects of nearly 20 steel companies at home and abroad. It has improved the production quality indicators of the sintering process while reducing carbon emissions by 16% and NOX emissions by 31.7%. This provides strong support for low-carbon production, high-quality products, clean emissions, and intelligent control of sintering, presenting significant implications for advancing the steel industry's 'dual carbon' strategic goals.
