SOFTENING AND MELTING BEHAVIOUR OF SINTER AND PELLETS.

Abstract

To evaluate high temperature properties of blast furnace burden, reduction under load tests were carried out under simulated blast furnace conditions using sinter, self-fluxing pellets, and acid pellets. Formation of molten slag is involved in the assimilation of slag during softening and melting and the basic path is toward the final composition along the expanding direction of the low melting temperature range with heating. Differences in softening and melting is due to the quantity of molten slag formed. It is indirectly due to differences in reducibility at temperatures above 1000 degree C in addition to the composition and volume of gangue before reduction.
