  • Recycling Ladle Furnace Slag as Flux in Steelmaking: A

    Sep 16, 2019· The use of synthetic fluxes in secondary steelmaking not only improves the properties of top slag and steel quality but also increases the production cost. Ladle furnace (LF) slag can be used as a replacement to synthetic fluxes owing to its chemical and mineralogical compositions. Valorization of LF slag helps in sustainable steelmaking and also reduces steel production cost.

    A new technique is presented to recycle ladle slag within the electric arc furnace through the injection system. The dilution of the chemical species contained in the slag and their combination with the species featuring the EAF slag afford a double advantage: the final slag is structured by chemical species that do not lead to the formation of powders and better stabilize the foaming slag.

  • 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.

    Recycling can be an efficient option to reduce such waste. Fluorspar (Calcium Fluoride) is generally used to help fluidize the slag; however, Fluorspar has a corrosive effect on the ladle refractory and is environmentally harmful. Alternatively, Calcium Aluminate synthetic slag is very effective in making the slag more fluid, but it is costly.
