Effect of Ternary Basicity of Iron Ore-Fluxed Pellets on ...

2020-10-27  Iron ore-fluxed pellets exhibit better softening and melting characteristics relative to acidic pellets. Basic fluxed pellets exhibit higher resistance to the initiation of softening, which leads to premature formation of the liquid phase. In terms of blast furnace operation, fluxed pellets tend to be in solid phase within a larger region ...
