Foundry Sand (Olivine)
Olivine foundry sand with a sinter point over 1350°C. Improves surface finish especially in manganese steel casting and reduces grinding costs; high thermal shock resistance and low thermal expansion prevent penetration of molten metal. Improves bonding with clay and reduces the bentonite requirement, provides gas permeability, high reuse ratio and no free silica. Supplied in AFS 30-35 to AFS 80-85 grades; an economical alternative to zircon and chromite.
EBT Filler Sand (Olivine)
Olivine-based filler sand for the eccentric bottom tapping (EBT) hole of electric arc furnaces. Easy opening of the tap hole with an opening ratio of 99%, sinter-free. High MgO content up to 51%, high melting point and refractoriness; improves the fluidity of the molten metal and contributes to clean steel casting.
Refractory Sand (Olivine)
Olivine sand as a natural refractory material over 1350°C. High MgO content up to 51%, high melting point and refractoriness up to 1760°C, high thermal shock resistance and low thermal expansion. Low impurities and LOI below 2%, low moisture and water absorption below 1%. Grain sizes 1-5, 2-5, 2-6, 2-7, 2-8, 3-6, 3-7, 3-8, 4-8 and 4-9 mm; other sizes and packaging available.
