Air-cooled blast furnace slag (BFS) It is a by-product of iron manufacturing, in which silica and alumina constituents combine with lime to form a molten slag collected on the top of the iron in a blast furnace. The slag issues from the furnace as a molten stream at 1400–1600°C. If this is allowed to cool slowly, it solidifies to a grey, crystalline, stone-like material, known as air-cooled ...
