    Effect of Ternary Basicity of Iron Ore Fluxed Pellets on

    Oct 27, 2020· An increase of MgO content in pellets alters the softening temperature and leads to a rise in the dripping temperature. [ 4, 9] Another beneficial effect of MgO is that itincreases the viscosityof the slag at 1450 °C. However, MgO decreases the viscosity at higher temperatures so that the slag drips together with the metal.
