High alumina bricks represent a specialised group of refractory resources engineered to withstand Excessive temperatures exceeding 1,790°C whilst sustaining structural integrity and chemical steadiness. These bricks possess high refractoriness, superb thermal shock resistance, and superior mechanical energy, generating them ideal for withstanding Serious temperatures and harsh functioning problems. The fundamental attribute that distinguishes high alumina bricks from standard fire bricks lies in their elevated alumina (Al2O3) articles, typically ranging from forty five% to 90%, which specifically correlates with their enhanced performance capabilities.
Ship us your furnace variety, running temperature, and amount—we’ll assistance you choose the very best high alumina brick Remedy for your requirements.
Glass Sector: Ideal for glass melting furnaces on account of their capability to withstand high temperatures and resist alkali attacks.
The amount and Qualities on the liquid period have a significant influence within the refractoriness underneath load. Hence, the reduction of the impurity material in raw content is in favor of increasing the refractoriness less than load and high temperature creep properties.

7. The high aluminum brick has higher thermal conductivity when compared to the clay brick, that's related to the lower of glass period in the high alumina brick and the increase of mullite crystal or corundum crystal.
Even so, higher grades are more brittle and high-priced. It’s essential to match the grade to the actual furnace problems—not only buy the highest alumina accessible.
The substitution of fireclay stopper rods and pouring nozzles with high-alumina (Al₂O�?>75%) versions has entirely prevented molten steel breakthrough incidents in ongoing casting functions.
Super responsibility fireclay brick may have a number of modifications together with higher firing temperatures than standard goods. Higher firing boosts the strength of your brick, stabilizes their volume and ceramic crucible mineral composition, improves their resistance to fluxing, and renders them pretty much inert to disintegration by carbon deposition in atmospheres made up of carbon monoxide gasoline.
Only once the transition to the refractory brick which consists Just about fully of corundum firebrick, that is certainly to mention, once the Al2O3 content material is more than ninety five%, high power at high temperature is obviously enhanced.
Alumina-based mostly refractorys are an indispensable material for industries that run under Serious temperatures and harsh problems. With their unmatched heat resistance, durability, and chemical balance, they offer a dependable Option to your refractory desires.

In the present demanding industrial landscape, tools failure due to Serious temperatures fees manufacturers thousands and thousands in downtime and replacement expenditures. High alumina bricks arise as being the crucial Alternative for these troubles, providing unparalleled thermal resistance and toughness in probably the most punishing environments.
