Steel slag contains significant quantities of iron; its highly compressed void structure results in a very dense, hard material. In 1992, 6.9 million t of steel slag was sold in the United States at a total value of $21.9 million. (The average selling price for steel slag at the plant was $3.02 per metric ton.)

0.2 to 0.4 tons of slag, and 2.5 to 3.5 tons of blast furnace gas containing up to 100 pounds (lb) of dust. The molten iron and slag are removed, or cast, from the furnace periodically. The casting process begins with drilling a hole, called the taphole, into the clay-filled iron notch at the base of the hearth.

Estimating the physical properties of slags
The structure of a slag can thus be represented by the mole fractions (X) of Oo, O-, and O2-present. Consequently, it is customary to divide various constituents into either network formers (e.g. SiO 2) or network breakers (CaO, Na 2O, etc.). However, when Al 2O 3 is added to a silicate slag, the Al3+ ion can be absorbed into the Si4+ chain but ...
