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.
