Direct Reduced Iron Technology
As Direct Reduced Iron (DRI) technology increasingly replaces traditional blast furnaces, the ironmaking industry is shifting towards more sustainable and cost-effective solutions. Unlike blast furnace processes, DRI uses reducing agents such as hydrogen (H₂), carbon monoxide (CO), methane (CH₄), and coal, significantly lowering CO₂ emissions. This gas–solid reduction process involves complex thermal and chemical interactions, requiring refractories that can withstand unique gas-solid phase flows and interfacial reactions. At Saint-Gobain Performance Ceramics & Refractories, we are at the forefront of developing advanced refractory solutions tailored for DRI shaft furnaces supporting the industry's transition to carbon neutrality by 2050 through innovative materials engineered for performance, durability, and environmental impact reduction.

FAQ
How does CORSHIELD™ meet the technical demands of modern DRI furnaces?
Key areas of the DRI furnace, such as the lower cone, bustle, and transition zones, are exposed to extreme thermal, chemical, and mechanical conditions. Our Corshield™ solutions are specifically engineered to increase the lifespan of these critical zones by countering abrasion and complex gas corrosion. By enhancing durability and reducing wear, they help minimize unplanned maintenance and extend furnace availability, contributing to more stable and cost-effective operations.
How is CORSHIELD™ sustainable?
CORSHIELD™ is manufactured in Ecovadis-certified facilities as:
- Silver in Halol, India;
- Gold in Palakkad, India.
Additionally, using 100 % green energy in our Italian Ecovadis-certified facility:
- Platinum in Mezzocorona, Italy.
What is the lifespan of CORSHIELD products?
As an example for the lower cone, DRI furnace operators have reported performance exceeding 15 years, significantly reducing maintenance and replacement needs.
