December 18, the global steel metallurgy green low carbon experiment and application project groundbreaking ceremony was held in the eight Iron and Steel Ou Smelting furnace rotary platform. As China Baowu low carbon metallurgy innovation experimental base, hydrogen-rich carbon cycle blast furnace is an innovative and disruptive carbon emission reduction, carbon neutralization process technology and demonstration project built on the basis of traditional blast furnace to break the technical bottleneck. Through hydrogen hydrocarbon reduction, carbon consumption of blast furnace ironmaking process will be further reduced. Achieve the recycling of output gas and carbon emission reduction of more than 30% of the target.
