A. Yazawa et F. Kongoli, Liquidus surface of newly defined "ferrous calcium silicate slag" and its metallurgical implications, HIGH TEMP M, 20(3-4), 2001, pp. 201-207
Ferrous calcium silicate (FCS) slag is defined as a new slag consisting of
FeOX, CaO and SiO2 with a nominal composition near the di-calcium silicate
surface. This slag is expected to solve the drawbacks of the "fayalite" and
ferrite slags. However, detailed knowledge of the liquidus surface of this
new slag is not available in the literature. Based on the authors' precedi
ng article, the available liquid region of FCS slag is confirmed under rele
vant oxygen potentials along with the effect of minor oxides. The liquidus
temperature is lowered by dissolution of copper oxide, and thus, FCS slag s
eems to be useful especially in the converting and direct smelting of coppe
r. The obtained knowledge should also be useful for various metallurgical p
rocesses.
