Development Advantages and Technical Upgrading Path of Short-process EAF Steelmaking Under the Dual Carbon Goals
Against the backdrop of the implementation of the dual carbon policies, transformation and upgrading of the iron and steel industry, and continuous improvement of the recycling system for scrap steel resources, short-process electric arc furnace (EAF) steelmaking boasts increasingly prominent core strengths of low carbon footprint, high flexibility and circular economy compared with the conventional long-process converter steelmaking. It has become one of the core development orientations for structural optimization and green low-carbon transformation of the iron and steel sector.
Benefiting from its unique process characteristics, EAF steelmaking features outstanding industrial adaptability and remarkable core advantages as follows:
Low capital investment: It requires less overall construction investment without supporting complex facilities such as sintering machines and blast furnaces, delivering a shorter infrastructure cycle and far lower upfront costs than long-process steelmaking.
Flexible production scheduling: It features a short smelting cycle and efficient, adjustable production rhythm, which can rapidly respond to fluctuating market orders and accommodate small-batch and multi-variety production demands.
Wide product coverage: It can precisely produce a full spectrum of steel grades including ordinary carbon steel, high-quality alloy steel and special steel, satisfying steel consumption demands from construction, machinery, military industry, new energy and other sectors.
Circular and low-carbon performance: It can efficiently recycle various renewable ferrous resources such as waste steel, industrial metal scraps and scrapped steel components, serving as the core carrier for circular economy in the iron and steel industry.
Convenient operation and maintenance: The equipment enables easy operation, quick startup and shutdown, and rapid working condition adjustment. Its production lines are easy to maintain with controllable labor costs, compatible with both mass production and flexible manufacturing scenarios.
In light of the current pace of technological iteration and low-carbon development requirements of the iron and steel industry, EAF steelmaking technologies will undergo continuous upgrading centered on four major dimensions: high-end manufacturing, lightweight production, green development and intelligent manufacturing.
