Steelmaking
The steelmaking process, where molten iron becomes solid steel, involves several stages of thermal and chemical treatment requiring a variety of refractory linings that are compatible with many application conditions.
These linings must have excellent resistance to steel and basic slag corrosion, as well as high thermal shock and oxidation resistance.
Saint-Gobain services this market with innovative refractories solutions that present high performances and contribute to enhanced steel quality.
