With the development of a large-scale blast furnace, hearth activity has an important impact on the longevity and efficiency. Based on the analysis of practical example of ShaSteel No. 3 blast furnace, the new hearth activity model was proposed and verified, namely, the slag-iron flow resistance coefficient. Besides, in the model, the prediction of the coke particle size in the hearth was used to predict the hearth activity. Furthermore, the slag-iron properties and coke properties were analysed to the influence degree on the resistance coefficient. The model has been applied to the hearth of ShaSteel No. 3 blast furnace, and it can timely respond to the internal state of hearth. Finally, the methods to activate hearth activity were explained, which not only has application value but also provides theoretical support for the evaluation of hearth activity in actual production.

“…Dinas rocks include materials containing silicon dioxide SiO 2 in the amount of over 93 % [6,7]. Fireclay refractory materials have been used in the lining of metallurgical assemblies in the production of coke, as well as an insulation material [6][7][8][9]. Dinas refractory materials, in contrast to fireclay, ensure masonry resistance to deformations at high temperatures and have a higher coefficient of thermal conductivity [8][9][10].…”

This paper aims at providing an overview of the ways for residue valorization in the iron and steelmaking industry. The important role of recycling in iron and steelmaking as a cornerstone for achieving a cleaner and resource-efficient potential is described. Several research results concerning metals and metal oxides (scrap, scale), slags, dusts, process gases, and water recycling from the iron and steelmaking process are reviewed here, aiming to detect those research gaps that still need implementation and suggest potential approaches toward potential solutions. Through a comprehensive evaluation, several possibilities are provided to incorporate effectively in metallurgical processes the bio-based or bio-derived carbon materials, namely biomass, biochar, biocoke, and polymers from waste plastics to reduce the dependence on fuel and reducing agents from fossil sources, and therefore mitigating the related environmental impact of the steel industry. Eventually, this review highlights the importance of embracing circular economy (CE) principles in iron and steelmaking, along with considering opportunities for industrial symbiosis (IS) and exploring the role of digitalization and digital solutions in recycling practices.
