Q
What is the minimum Al2O3 content in these refractory balls?
The chemical composition contains an Al2O3 (Alumina) content of ≥ 65%, ensuring high thermal stability and chemical resistance.
Q
What is the maximum refractoriness temperature limit?
The refractory balls have a refractoriness rating of ≥ 1800 °C, making them suitable for severe high-temperature industrial environments.
Q
What is the compressive strength rating?
The compressive strength is rated at ≥ 900 kg/cm², providing superior mechanical support and resistance against crush or breakdown under load.
Q
How do these refractory balls perform under physical load at elevated temperatures?
Under a mechanical load of 2 kg/cm², the refractoriness under load rating remains ≥ 1500 °C, preventing structural deformation during high-heat operations.
Q
What are the bulk density and specific gravity properties?
The bulk density is ≥ 1386 kg/m³ with a specific gravity of ≥ 2350 kg/m³, reflecting high density and optimal structural compactness.
Q
What is the pore volume and Loss on Ignition (LOI) standard?
The pore volume is strictly maintained at ≤ 24%, with a Loss on Ignition (LOI) value of ≤ 0.1%, ensuring high purity and minimal volatile components.
