• Introducing CORSHIELD™

    Innovative refractories for DRI applications
    CORSHIELD

    Direct Reduced Iron (DRI) is transforming iron production by providing a more environment friendly alternative to the traditional blast furnace route. 

     

    As the industry advances towards low CO emission iron and steel making, the demand for cutting-edge refractory solutions that can withstand the unique challenges of DRI shaft furnaces, especially with elevated hydrogen (H2) levels, is growing. 

     

    Our refractory bricks are engineered to meet these demands, offering sustainability combined with durability towards abrasion and complex gas corrosion. Rely on our innovative materials to boost the effciency and longevity of your DRI processes.

  • FAQ

    How is CORSHIELD™ sustainable?
    Ecovadis

    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.
       
    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.
    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.
