Abstract
The effects of pisolitic ore on the melting reaction rate and the flui dity of the melt were investigated to make clear the mechanism of the decrease of the sinter yield with the blending of pisolitic ore. Pisol itic ore, characterized by the high porosity, increases the melting de pth by the promotion of melting reaction through the pore. As a result , CaO/(CaO+Fe2O3) in the melt decreases and the liquidus temperature o f the melt rises. Thus, the time available for the pore rearrangement is decreased and the distribution of pore size changes with the blendi ng of pisolitic ore.
