Slag is a valuable resource for any steelmaker. Integrated steelmakers sell blast furnace slag - which is naturally cementitious in quality - into the cement industry. In addition, the slag from the BOS plant such as converter slag and ladle slag has useful properties once weathered to allow for expansion of the lime-bearing material.
The ground granulated blast furnace slag (GGBFS) is a by-product of iron manufacturing which when added to concrete improves its properties such as workability, strength and durability. This material is obtained by the heating of iron ore, limestone and coke at a temperature about 1500 degree ...
The furnace roof could be swung aside for top charging, and a slag door was located on the side opposite the taphole for access to the molten bath. The entire furnace could be tilted for tapping. Figure 1 shows a layout of the furnace, scrap feeder-preheater, and furnace offgas ductwork including gas sampling location and dust removal units.
