Recently, the Steelmaking Plant of Baosteel Desheng has achieved a record-low steel material consumption index by focusing on lean production and extreme cost reduction. By optimizing production processes, refining equipment operation and building a full-process iron-bearing resource recycling system, the enterprise has bolstered high-quality and green low-carbon development.
Abandoning the traditional extensive waste disposal mode, the plant has realized full recycling of steel slag, casting residual slag, iron oxide scale, dedusting ash and furnace residual steel. It adopts 100% in-furnace reuse of steel slag, and standardizes the collection, transportation and reuse of all iron-containing waste across working procedures. Optimized recycling technologies greatly improve the utilization rate of secondary iron resources, effectively reducing metal loss and solid waste stockpiling, and forming a closed-loop production cycle.
Industry Insight on Sustainable Development
The transformation fully demonstrates that the sustainable development of the steel industry relies on whole-process resource optimization rather than simple terminal pollution control. As a resource-intensive industry, steel manufacturing must reduce reliance on primary mineral resources through circular utilization of secondary resources, which enhances industrial resource security.
Green and circular production has become the core competitiveness of modern steel enterprises. On-site solid waste recycling cuts carbon emissions, reduces environmental pollution and lowers production costs, achieving a win-win of economic and ecological benefits. Meanwhile, low-carbon and recycled production helps reduce product carbon footprints, meeting the growing market demand for green steel products and supporting the long-term sustainable development of the steel sector.
Going forward, Baosteel Desheng will continue to upgrade circular production technologies and digital management systems. It will promote replicable green recycling standards for steelmaking production, further integrating cost reduction, lean production and low-carbon transformation, and setting a practical benchmark for the sustainable development of the steel industry.
