The CaO/SiO2 ratio and the MgO content of the blast furnace slag greatly influence its softening-melting properties. The availability of MgO later in the process often results in small temperature range of cohesive zone resulting in better permeability of the bed which in turn influences the coke consumption and quality of hot metal produced.
