The Upgrading And Greening Of Ordinary Carbon Steel

Carbon steel accounts for approximately 70% of China's steel production. Its production scale and application scope are both among the highest, exerting a profound influence. In the next step, we should fully rely on China's abundant rare earth resources such as lanthanum, cerium, and yttrium to develop new varieties of corrosion-resistant carbon steel, significantly extending the service life; at the same time, combined with the latest achievements in physical metallurgy, we should establish a high-strength and high-toughness technology system that can be widely promoted, increasing the yield strength from the current 200 MPa level to 400 MPa level, achieving steel reduction and resource conservation; and in line with the development trend of the short process of electric furnaces from scrap steel, we should develop new steel materials containing nitrogen and compatible with scrap steel impurities, providing core support for green and low-carbon metallurgy.

Green Rare Earth Corrosion-Resistant Carbon Steel Technology with Chinese Characteristics
  • Develop a type of rare earth corrosion-resistant  carbon steel with Chinese characteristics. Corrosion is one of the main failure modes of steel materials. It is necessary to solve the corrosion problem of large-scale and widespread carbon steel (accounting for about 70% of the total output) in a low-cost and green manner. Rare earth corrosion-resistant carbon steel effectively utilizes China's abundant lanthanum and cerium rare earth resources, endowing  carbon steel with atmospheric corrosion resistance (increasing by 30%-50%). The cost of rare earth alloy per ton of steel is less than 10% of that of traditional weather-resistant steel alloys. It is a new type of green and low-cost steel. The series of rare earth corrosion-resistant carbon steel products include hot-rolled strip coils, hot-rolled plates, rebar, wire rods and sections, with strength levels ranging from 195 to 550 MPa. It is applied in fields such as steel structures, highway guardrails, communication tower, photovoltaic supports, protective wire meshes, urban decoration, containers, and building rebar.

Micro-Grain Steel Technology
  • Based on the basic research achievements and the installation improvements, the highly-strengthening and well-ductilizing technologies on micro-grain refinement and M3 microstructure adjustment and optimization ideas are applied to increase the mechanical properties of plain low carbon steels such as strength and toughness, and some approach to the levels of micro-alloyed steels. The technical potential of processes and installations can be fully exploited on the new developments in physical metallurgy to decrease the alloy consumption and reduce the alloying costs of steel products.

    Based on the theories of both deformation induced ferrite transformation (DIFT) and the M3 microstructure adjustment and optimization, the Independent Intellectual Property Right technologies for micron-grained steel plate manufacture process have been developed so that both the material strength is increased and the toughness is improved.

Green Urban Steel Plant
  • Centered on a scrap-based electric-arc-furnace (EAF) short process, we consume the city’s scrap on site and develop new steel grades tailored to EAF’s high nitrogen and multi-element scrap feedstock, directly serving urban economic growth. Under ever-tightening caps on energy consumption and environmental impact, we re-engineer the steel-plant paradigm along a “resource–environment–urban function” axis, forging a true symbiosis of steelworks and city.
