    Steel Making

    The steel making 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.

    Steel making Equipment, RH Degasser | Saint-Gobain

    RH Degasser

    The RH degassing system is essential for steel shops to meet the modern specifications of steel quality. This equipment process requires a special kind of refractory, the ultra-high temperature MgO-Cr2O3 fired bricks, that have excellent corrosion resistance and thus achieve longer operation life. The recent developments of Saint-Gobain in partnership with a Japanese refractory supplier have also made possible to reach high resistance to thermal cycling in its projects.

    Steel making Equipment, Flow Control | Saint-Gobain

    Flow Control

    The final process in which the steel is liquid, the continuous casting requires a series of special refractories that have an enormous influence on the final steel quality. They are responsible for controlling the flow rate, protecting from oxidation, facilitating the inclusion flotation and allowing a good flow pattern inside the mold. The Saint-Gobain refractories division works together with a very strong Japanese partner in order to deliver high quality and high performance products for this segment.
