Corundum Castable: Premium Monolithic Refractory for Harsh High‑Temperature Furnaces

TY Refractory’s high‑performance Corundum Castable is an unshaped refractory formulated from fused white corundum, fine alumina ultrafine powder and calcium aluminate cement binder. Every Corundum Castable features low‑porosity dense matrix, outstanding wear‑resistance and high compressive strength for heavy‑duty industrial furnace linings.

This reliable Corundum Castable reaches core technical indicators: Al₂O₃ content ≥90%, bulk density 2.8‑3.0 g/cm³, cold crushing strength above 80 MPa, maximum service temperature up to 1800°C with linear change rate controlled within ≤1.0%. Each Corundum Castable forms seamless integral lining after pouring and curing, effectively resisting erosion from molten metal, slag and aggressive chemical vapors.

The versatile Corundum Castable fits multiple scenarios: metallurgical furnaces, hot‑blast stoves, ferroalloy ladles, waste incinerators and CFB boilers. Custom‑tailored Corundum Castable formulations are available for unique operating parameters and complex lining geometries.

Backed by over 20‑year refractory manufacturing experience, our factory holds complete ISO triple‑system certifications and 21 proprietary technical patents. Strict batch lab testing guarantees stable quality for every Corundum Castable. Global industrial operators select our Corundum Castable to extend furnace campaign cycles and cut frequent repair expenses.
