Alumina Castable
Semirom Refractories produces a wide range of refractory masses and mortars using high-quality local raw materials and modern technical expertise. Backed by decades of experience, these products are designed وفق international standards and deliver reliable performance in harsh conditions.
Semirom refractory masses include castable, gunning, and ramming types, offering high resistance to thermal shock, mechanical wear, and corrosive environments—ideal for furnaces, boilers, reactors, and other industrial equipment.
Technical Features of Semirom Alumina Masses
What we do today shapes the future of the refractory industry:
Al₂O₃ content from 30% to 90% (depending on grade)
High thermal stability
Strong resistance to wear, slag corrosion, thermal shock, and oxidation
Suitable for alkaline, acidic, and highly corrosive environments
Applicable for casting, ramming, and gunning
Excellent adhesion to refractory and metal surfaces
Main Applications of Alumina Masses
- Electric arc furnaces and steel converters (EAF, BOF)
- Ladles, furnace walls, and floors
- Non-ferrous industries: copper, lead, aluminum
- Protective linings in cement and lime rotary kilns
- High-corrosion zones exposed to acidic gases or slag
