Refractories for Foundry

Refractories parts made of zirconium oxide

Major technical evolutions have occurred in the steel foundry industry over the last 30 years, driven by demands for improved steel quality, manufacturing process optimization and cost reduction. This has triggered the development of performance-enhanced refractories with higher resistance to thermal shock, corrosion, erosion and wear.

Through its extensive technical expertise and industrial competencies, Saint-Gobain ZirPro offers a comprehensive range of fine monoclinic zirconium dioxide powders (CC, CS, CF, CZ and CZE grades) suitable for the manufacturing of molten metal filters and specialty refractory parts.

Zirconia-based refractories for better performance and longer lifetimes

Molten metalf poured in zirconia-based ceramic filter

Zirconium dioxide-based refractories increasingly have been used in demanding applications such as the continuous casting of steel and alloys due to their superior performance and longer life. Zirconium dioxide-based compositions are used in molten metal filters for the filtration of steels and alloys in which high chemical purity and product reliability are required.

Here are several examples:

  • Molten metal filters for the aircraft and power industries
  • Nozzles and slide gates for optimized control of the steel casting process

Industry standard for monoclinic zirconia grades

ZirPro’s thermally and chemically derived zirconia grades (CC, CS, CF, CZ and CZE) offer a wide range of fine particle sizes (from 15 µm down to 0.5µm) for better adjustment and control of the final part properties, including shrinkage and porosity of the filters and densification of structural parts. ZirPro’s high chemical purity grades (CZ and CZE) also enable better mechanical performance and longer life.
