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.

Electric Arc Furnace (EAF)
The Electric Arc Furnace (EAF) is an essential tool for reprocessing steel scrap, helping reduce the steel industry’s carbon footprint. This extremely aggressive process requires a large quantity of high-quality refractories.
Refractory materials are essential to electric arc furnace operation. They act as the containment system for liquid steel, reaching temperatures up to 1500°C. Protecting the vessel's integrity over time, refractories ensure resistance to corrosion, oxidation (atmosphere and burners), erosion (scrap charging) and thermal shock.
By using electricity, the electric arc furnace is a key process in this evolution toward less CO2 emission-intensive steelmaking processes. The temperatures reached in the electric arc furnace process exceed those needed for smelting standard steel, making electric arc furnaces suitable for processing alloy and stainless steel.
Bricks and monolithics from Saint-Gobain Performance Ceramics & Refractories are manufactured using carefully selected raw materials and stringently controlled processes to ensure resistance, quality, and safety.
