CSC mainly planned 3 technology cores in the development of low carbon blast furnace technologies, including (1) adding low carbon charge; (2) hydrogen-rich gas injection; (3) gas CO2 capture and modification, in which the first two items are short-term and mid-term implementation goals. For low carbon charge, the Company has successfully developed technology for adding reduced iron in blast furnace, and successfully added 150 kg of reduced iron pellets to each tonne of hot metal during testing. Due to the significant carbon reduction effects, 50 kg of reduced iron is regularly added to each tonne of hot metal at #3 blast furnace with consideration to the production volume of reduced iron. With regard to hydrogen-rich gas injection, the Company plans to inject hydrogen-rich COG into the blast furnace before it obtains green hydrogen, and will use hydrogen to replace coal to reduce carbon emissions from the blast furnace. CSC has referenced overseas cases and technologies and successfully designed a blast furnace simulator for multiple layers of high temperature materials during hydrogen-rich operations, which can be used to evaluate the reaction characteristics from the material surface to the dripping charge. The equipment completed cold and hot commissioning at the foreign equipment manufacturer's plant before shipment in October 2022, and system installation has completed. It is worth noting that CSC utilizes the capabilities of academia by jointly forming a research team, and submitted an application to the NSTC for the development of low carbon blast furnace technology. The application was approved by the NSTC as an Advanced Technology Industry-Academia Collaboration Project, and was implemented in November 2022 with the 3 core technologies described above, engaging in 16 research projects.
