Saint-Gobain has developed and patented a complete range of chromia and chromia-alumina products that provide outstanding performance.

As the industry leader since the late 1970s, Saint-Gobain has developed and patented a complete range of chromium oxide-alumina-zirconia refractories, marketed as Zirchrom®, refractories for the hot face layer. Several compositions especially engineered for low or high wear areas are available. These products offer high slag infiltration and chemical corrosion resistance as well as advanced thermal shock resistance, which are key factors for quick operations response and outage time control. These products are continually improved by the company’s ongoing commitment to research and development.

Chromium-oxide Zirchrom® bricks have been installed as hot face material, whereas alumina-chrome Chromcor® 12 and andalusite-based MS6 mullite bricks are available for the back-up layers. Bubble alumina RI 34 or Alundum® AN599 insulating fire bricks are used for thermal insulation.
