    6. Mechanisms of cast iron and slag formation

    Liquids are formed in the "reactor" located beneath the blast furnace's melting zone, in particular the crucible, by the transfer of gas, solid and liquid matter. . The gangue of the various "pure" materials making up the blast furnace charge is characterized by liquidus temperatures that are generally much higher than those of the final liquid slag, which explains the need to use fluxes (figure 20...
