Green Metallurgical Process and Technology

Dear Colleagues,

Iron and steel are industries with high energy consumption and carbon dioxide emissions, and green manufacturing these processes has become the trend of future development. The process of iron and steel production involves blast–converter and electric arc furnaces. The blast–converter furnace process is also known as the long process, the production of steel is called converter steel. In this process, iron ore and coke as the main raw materials are first smelted into hot metal and then into steel by the converter. On the other hand, the electric arc furnace process is known as the short process. The steel produced is called electric furnace steel, which is smelted into steel with scrap steel as the main raw material. Around 70% of the energy used in the metallurgy process is wasted during the steelmaking process. It is therefore important to master the mechanisms of both the long and short processes in steelmaking and recover the waste heat.

Recent advances in energy recovery and advanced technology for the metallugy process have attracted attention. These include hydrogen smelting, electric furnace steelmaking, and high-nitrogen steel smelting technologies and the recovery of waste heat from metallurgical processes, amongst others. To achieve green metallurgical processes and technology, it is necessary to decrease energy consumption in iron and steel production. This Special Issue is aimed at all researchers and technologists interested in all aspects of the science, technology, and applications of green metallurgy processes and technology. It will feature original research papers and reviews related to hydrogen smelting, electric furnace steelmaking, high-nitrogen steel smelting, and energy recovery. We invite scientists working in the area of renewable energy and green metallurgy technology to contribute to this Special Issue.

“Green Metallurgical Processes and Technology” aims to gather novel advances in reducing energy consumption and CO₂ emissions during the metallurgy process. Potential topics include the following:

1. Hydrogen, low-carbon, and high-nitrogen smelting technologies;
2. CO₂ resource utilization;
3. Electric furnace steelmaking;
4. Recovery of waste heat from metallurgical slag.
