Renewable Energy and Green Metallurgy Technology
Xin yao & huaqing xueand steel industry is an energy-intensive and CO2-intensive industry that accounts for approximately
5% of the world’s energy consumption. Energy conservation and emission reductions in the iron
and steel industry will play a significant role in achieving sustainable development. Mastering the
principle of advanced metallurgical technology, using renewable energy to replace fossil fuels and
recycling the waste heat of steel production process could provide a guarantee for the green and
high-quality development of the metallurgical field.
The Special Issue “Renewable Energy and Green Metallurgy Technology” focused on green
metallurgy production was established by Dr. Xin Yao from North China University of Science
and Technology and Dr. Huaqing Xie from Northeastern University. It summarizes the advanced
technology of iron and steel enterprises, and mainly presents the latest research results for six
research directions, such as biomass energy and solar energy as replacements for fossil fuels,
resource utilization of metallurgical slag, low-carbon smelting technology in steel, CO2 resource
utilization, strengthening mechanisms and smelting processes of non-quenched and tempered steel
for automobiles, high-nitrogen steel smelting technology. Thirteen papers were finally accepted and
published in the Special Issue. The papers in the Special Issue proposed a new method for predicting
defects in non-oriented silicon steel billets, established a heat transfer model during the process of
centrifugal fiber formation, presented the solid-state decarburization method, illustrated recovery
waste heat from the iron and steel process, and described the mechanism of iron and steel production.
