Ladle Slag - an overview ScienceDirect Topics

The liquid hot metal and slag are tapped from the blast furnace intermittently or continuously depending on the size of the furnace. Hot metal is tapped into a torpedo car which is transported by rail to the hot metal pretreatment station, and the blast furnace slag is tapped into a slag ladle which is transported by trucks to a slag pit.

Ladle Furnace slag - AEIFOROS METAL PROCESSING S.A

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. Due to high CaO concentrations the material can be used in the production process of cement, as a limestone replacement.
