steel research international, Volume 92, Issue 9, September 2021., 2021 More than 1200 heats are used so as to investigate the benefits of the powder lime injection in a 90 t electric arc furnace (EAF) and compared with the traditional addition of lime in lumps. Savings above expectations are observed for electric consumptions and lime charged, also reducing CO2 emissions for both the production of structural and special ...
