Webb8 mars 2016 · There are several different types of steel slag produced during the steel-making process. These different types are referred to as furnace or tap slag, raker slag, synthetic or ladle slags, and pit or cleanout slag. Figure 18-1 presents a diagram of the general flow and production of different slags in a modern steel plant. WebbLadle slag is produced during the secondary refining of steel and is a valuable source of calcium oxide for the cement industry. Ladle furnace slag is produced through the addition of lime (CaO), and dolomitic limestone (CaO.MgO) in the electric furnace. The resulting byproduct, ladle furnace slag, contains high concentrations of calcium oxide.

WebbSteel slag and old bank slags may undergo volumetric expansion in the presence of water. The risk of damaging expansion occurring when using steel slag produced in modern processes is minimised by a combination of careful production control and processing. Air-cooled blast furnace slag is non-expansive.
