Delivering engineered high alumina, corundum, mullite, and composite refractory bricks designed for high thermal stress, mechanical abrasion, and alkali resistance across Brazilian steel, cement, aluminum, and petrochemical industries.
Engineered refractory solutions built to withstand harsh chemical environments, rapid temperature shifts, and extreme structural loading in Brazilian heavy manufacturing.
Brazil represents Latin America's largest hub for metallurgical processing, mining, bauxite refinement, and infrastructure development, driving unprecedented standards for refractory linings.
Integrated blast furnaces, electric arc furnaces (EAF), and secondary ladle refining across Minas Gerais and Rio de Janeiro demand high alumina bricks (Al2O3 55%-85%) with superior hot rupture modulus (HMOR), high refractoriness under load (RUL >1500°C), and exceptional slag resistance.
Brazil’s booming infrastructure projects require large-diameter rotary kilns in São Paulo and Paraná. High alumina bricks are strategically placed in burning transition zones, cyclones, and precalciners where alkali bypass systems and alternative fuels (AFR) generate severe chemical corrosion.
Brazil holds some of the world's richest bauxite reserves. Smelters and holding furnaces in Barcarena and northern regions rely on phosphate-bonded high alumina bricks and mullite-corundum linings to resist molten aluminum wetting and cryolite vapor penetration.
How our high alumina refractory series resolves operational bottlenecks in tropical climates and intensive continuous production lines.
| Industrial Application in Brazil | Recommended Brick Grade | Al2O3 Content (%) | Key Operational Benefit | Typical Service Area |
|---|---|---|---|---|
| Blast Furnace & Stoves | SK-HA80 / Mullite Brick | 75% – 85% | High creep resistance, low porosity (<18%), high RUL (>1550°C) | Checker chambers, combustion wells, hot blast mains |
| Cement Rotary Calcining | Phosphate-Bonded / Spinel HA | 65% – 75% | Thermal spalling resistance against alternative fuel alkaline buildup | Preheater cyclones, calciner hoods, transition zones |
| Steel Ladles & Tundishes | Corundum-Spinel & High Alumina | 80% – 90% | High mechanical strength, resistance to molten steel and slag penetration | Ladle safety lining, working linings, impact pads |
| Petrochemical & Gasifiers | Dense AZS / Chrome-Alumina | 65% – 82% | Chemical stability in aggressive reducing carbon and sulfur atmospheres | Reactor vessels, fluid catalytic cracking (FCC) regenerators |
| Glass Furnace Regenerators | Zero Expansion Fused Silica / Mullite | 70% – 99% | Near-zero thermal expansion, unyielding thermal shock resistance | Crown structures, checker packing, burner blocks |
