Abstract：The scientific coke evaluation indicators are beneficial for controlling the raw material cost of coke and making more rational use of coking coal resources,so the performance evaluation of coke in blast furnaces is crucial for smelting efficiency,output and product quality.The purpose of the work was to count the research directions,hotspots,and research progress of cokes in performance evaluation in blast furnaces from 1994 to 2023.Research materials were based on related articles from China National Knowledge Infrastructure(CNKI)and Web of Science(WOS).Bibliometrics was used to analyze the number of articles,research disciplines,research institutions and au-thors,keywords,research content trends,and cutting-edge hotspots in coke performance evaluation in blast furnaces from 1994 to 2023.Software CiteSpace was used to draw a keyword map,a keyword timeline map,and a keyword e-mergence map of cokes in performance evaluation in blast furnaces.Software Office was applied to analyze relevant data.The domestic publication volume of cokes in performance evaluation in blast furnaces has experienced three pe-riods of rapid rise,dynamic balance,and steady rise since 1994.The foreign publication volume was zero between 1994 and 2009;it has experienced two periods of explosive increase and steady increase since 2010.Meanwhile,the articles on coke performance evaluation in blast furnaces involved multiple disciplines,reflecting the interdisciplinary characteristics.The research field of performance evaluation of cokes in blast furnaces has been accompanied by an increase in the importance of environmental protection.The emphasis was placed on the thermal properties,optical structure,coking coal,and the microstructure of cokes within the domestic research landscape.In contrast,the in-ternational focused on the reaction behavior of cokes within blast furnaces as well as applications related to CO2 cap-ture and other environmental technologies.Therefore,strengthening the all-element pattern of basic research,tech-nological innovation,and interdisciplinary integration plays an important role in improving the science and application of coke performance evaluation in blast furnaces.Results can promote the metallurgical industry in a more efficient,environmentally friendly and sustainable direction.
