Outline
In order to achieve green, low carbon and high−quality development of the iron and steel industry, the development and application of low carbon emissions steelmaking technology should be noted. The study systematically analyzes the structural transformation of the current steelmaking process, with a focus on achieving low−carbon operation in the converter process through high scrap steel ratio smelting and the use of clean raw materials such as direct reduced iron (DRI). At the same time, an in−depth analysis was conducted on how electric arc furnace steelmaking technology can move towards the forefront of low−carbon and even "near zero carbon" smelting through technological solutions such as green electricity, intelligent power supply, biomass carbon sources, and reducing auxiliary material consumption. Finally, a systematic low−carbon emission steelmaking development path was proposed from the dimensions of technology integration, policy guidance, and energy structure transformation, providing theoretical support and practical reference for the high−quality and sustainable development of the steel industry.
