Brown Fused Alumina Refractory Aggregate

High-density, thermally stable aggregate for castables, precast blocks, and monolithic linings in steel, cement, and non-ferrous industries.

0–1 mm 1–3 mm 3–5 mm Refractory Castables Precast & Ladle Linings
Brown fused alumina refractory aggregate for ladle linings and castables

Why Choose Our Refractory Aggregate?

Engineered for extreme temperature performance and slag resistance

High Refractoriness

Withstands temperatures above 1800°C, suitable for harsh furnace and steel ladle environments.

Low Porosity

Dense microstructure limits slag penetration and maximizes thermal insulation in refractory linings.

Slag Resistance

High alumina content and inert chemistry prevent degradation in contact with molten slags and fluxes.

Stable Particle Shape

Angular and blocky grain structure enables superior particle packing in castables and precast forms.
