Core Viewpoint - The traditional steel industry is undergoing a transformation towards greener practices through innovative technologies that enhance energy efficiency and reduce carbon emissions [3][11]. Group 1: Project Overview - The "Key Technologies for Extreme Energy Efficiency and Carbon Reduction in Ironmaking Process" project, led by the Wuhan Municipal Science and Technology Bureau, involves collaboration among ten entities including Wuhan Iron and Steel Co., Huazhong University of Science and Technology, and others [3][11]. - A milestone achievement event was held on August 8, showcasing the project's progress and results [3]. Group 2: Key Technological Innovations - A new boiler system capable of "eating" waste gas has been developed, which efficiently recovers medium and low-temperature waste heat while simultaneously removing harmful substances like NOx and dioxins. This technology is currently being demonstrated at Shanxi Gaoyi Steel Company, with an expected annual coal savings of over 10,000 tons and significant reductions in pollutant emissions [6][11]. - The "Anti-Cycle Stress Raw Gas Waste Heat Recovery System" extends the lifespan of coke ovens, having been tested for 230 days without damage. It is now applied to 140 coke ovens at Wuhan Steel, projecting a lifespan extension to over 16 years, annual savings of 23,400 tons of standard coal, a reduction of 60,000 tons of CO2 emissions, and an economic benefit of 48 million yuan [7][11]. - The AI "fire eye" system for blast furnaces enables real-time monitoring and intelligent diagnosis of critical processes using high-precision cameras and smart algorithms. This system has been implemented in Wuhan Steel's No. 5 blast furnace and is being expanded to other furnaces [7][11]. Group 3: Industry Impact and Future Directions - Experts agree that the project's technologies reach internationally advanced levels and have significant demonstration value, marking a milestone for the industry's green transformation [11]. - The project is the 20th major technology initiative organized by Wuhan City, focusing on energy-saving and carbon reduction challenges in the steel sector, thereby injecting new productive forces into the traditional high-energy-consuming industry [11].
