WebThe results of the reduction rates of different carbonaceous materials in FeO-bearing slag showed that the reduction rates of fixed coke rods were slightly worse than those of graphite rods. This is mainly because coke contains a certain amount of ash that hinders the direct contact between slag and solid carbon as the reduction time increases. WebNov 3, 2003 · In the present study, wettability of slag/carbon systems has been investigated by measuring the variation in dynamic contact angle at the slag/carbon interface with time, for different slag compositions and carbonaceous materials, at 1500°C. The influence of liquid and solid composition on wetting has been discussed.
