Flux for blast furnaces and sintering
Dunite is a mineral used as a flux in the steel industry, particularly in blast furnace and sintering processes. Its high content of magnesium oxides (MgO) and low levels of impurities make it an efficient and sustainable alternative to traditional fluxes, improving slag formation and optimising coke consumption.
Main uses in the steel industry
- Blast furnaces: acts as a flux in slag formation, enhancing impurity removal and stabilising the smelting process.
- Sintering: promotes the formation of a porous and homogeneous sinter matrix, improving permeability and efficiency in the reduction process.
- Process optimisation: its use contributes to greater thermal efficiency and a reduction in coke and lime consumption in pig iron production.
Key advantages of using dunite in steelmaking processes
Provides greater slag stability, improving furnace efficiency.
Reduces coke consumption, lowering costs and environmental impact.
Enhances sinter quality, optimising blast furnace burden.
Offers a sustainable alternative to other minerals, contributing to carbon footprint reduction.
