Ranking of Injection Biochar for Slag Foaming Applications in Steelmaking

The electric arc furnace (EAF) has the potential to significantly contribute decarbonization of iron and steel industry. However, during EAF steelmaking, carbon still needs be injected into molten slag initiate foaming, which is beneficial energy efficiency protection furnace. To move away from fossil carbon, biocarbon gained attention as an injection agent. In this study, two biochar candidates were added layer induction for melting, simulate steelmaking conditions. resultant foaming height was measured, a ranking in comparison developed. results indicate that sample, form bio-briquette, considerable degree capacity. More work ongoing develop standardized testing methodology various their suitability qualification use on larger scale.
