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.

Flow Control

Crude steel production begins with the reduction process, where the iron ore reacts with carbon sources inside the blast furnace. The blast furnace requires different types of refractory products with resistance to thermo-mechanical and thermo-chemical reactions.
Continuous casting is the final process in which the steel is liquid, requiring the use of a series of specialized refractories that have an enormous influence on final steel quality.
These refractories are responsible for controlling flow rate, protecting steel from oxidation, facilitating inclusion flotation and ensuring a good flow pattern inside the mold.


Saint-Gobain Performance Ceramics & Refractories has recently begun working in partnership with a high-profile Japanese refractory supplier to deliver high quality and high performance flow control products.
