Investigation of the Impact of Biochar Application on Foaming Slags with Varied Compositions in Electric Arc Furnace-Based Steel Production

This paper investigates the influence of biochar, either as an individual component or in combination with high-temperature coke, on slag foaming behavior. High-temperature coke serves a reference. Three scenarios were considered to study behavior, each characterized by different chemical compositions. The results indicate that biochar can promote steady for specific slags when basicity (CaO/SiO2) falls within range 1.2 3.4. Experimental findings also reveal stable be achieved mixture containing and ratio 1:1 is employed, minimum 1.0 FeO content 25 wt.%. obtained using contents (15 wt.% 40 wt.%) surpasses observed application biochar. X-ray diffraction (XRD) analysis showed unrelated carbon source applied, general pattern was phases larnite (Ca2SiO4) dicalcium silicate detected foams high basicity.
