Influence of Chemical Compositions of Slag and Graphite on the Phenomena Occurring in the Graphite/Slag Interfacial Region
|
Silica reduction reactions taking place in the slag/carbon interfacial region were investigated for synthetic/natural graphite in the temperature range 1500 °C to 1700 °C. Two silica-rich blast furnace slags, with low levels of iron oxide, were used in this study. Silica concentration in these slags, labeled as 1 and 2, was 30.80 pet and 36.80 pet with a respective basicity of 1.67 and 1.22. Reaction rate investigations were supplemented with wettability measurements on these systems with a...

Sludge or slag? One can be sold as scrap to be recycled. The other fits federal and state agency definitions of solid waste. And as one Ohio company discovered the hard way, using the right name can make all the difference between a new revenue source, or bankruptcy.
Pollution Engineering
; An Ohio company manufactures shot for abrasives from scrap steel melted in an induction furnace. Slag is removed and the molten metal poured into a spinner bucket that spins and casts the material as shot, which is quenched with water. The shot is extracted from the casting pit and the quench water
