The first national demonstration project of short process steelmaking with a near-zero carbon-emission electric furnace in China, jointly built by a research team from the University of Science and Technology Beijing and CITIC Pacific Special Steel Group, has been put into operation at Jingjiang Special Steel.
This subsidiary of CITIC Pacific Special Steel Group is located in the Jingjiang Economic and Technological Development Zone in Jingjiang, Jiangsu province.
Relying on core technologies such as 100 percent green electricity direct supply, non-carbon-related smelting, and the digital twin concept, the project's production line achieves nearly zero carbon dioxide emissions in the steelmaking process, with a comprehensive emission reduction efficiency rate of over 90 percent.

Unlike traditional steelmaking that relies on ore and coal, the production materials of Jingjiang Special Steel are recycled steel from scrapped cars and old equipment. The project adopts biomass gas and biomass charcoal to replace traditional fossil fuels, utilizes green energy such as photovoltaics and wind power, and uses super electric furnaces to replace coal with electricity to remelt and smelt waste steel, producing high-quality special steel.
"The project has an annual production capacity of 500,000 metric tons of low-carbon special steel, providing reference for the green and low-carbon transformation of the steel industry," said Chen De, deputy manager of the Jingjiang company.
