Phosphate-bonded high alumina brick is chosen in several aluminum furnace linings because the phosphate will cause the brick for being proof against wetting and penetration by molten aluminum. Phosphate-bonding also increases the refractory Qualities by expanding density, lowering porosity, rising toughness, and abrasion resistance.
High alumina brick refractories can have two bond systems, ceramic, and phosphate. Phosphate brick is quickly acknowledged by a phosphorus pentoxide (P2O5) content material on their own info sheet of in between about three% and 6%.
one. On the list of significant Functioning Qualities of high alumina refractory brick is the composition power at high temperature. This attribute is often evaluated from the deformation temperature of refractoriness.
It may substitute fireclay bricks in all high-temperature units, and substitute silica bricks in particular sections.
For instance, resistance to penetration and wetting by molten aluminum is usually improved with a phosphate bond. Speak to your Resco sales representative or field specialist to ascertain proper high alumina brick for your personal application.
These bricks are made by firing Uncooked products like bauxite and kaolin at high temperatures, resulting in a dense, tough merchandise which will withstand Extraordinary heat and severe conditions.
A Resco sales consultant or industry apps specialist may help you pick the right alumina brick to your software.
High alumina bricks are available in standardized shapes and sizes, nevertheless personalized dimensions are available for specialised installations.
Requesting samples and checking out the plant (or verifying through movie) is highly proposed for bulk specials.
Only if the transition for the refractory brick which is composed Nearly completely of corundum firebrick, which is to say, when the Al2O3 content is greater than ninety five%, high energy at high temperature is obviously enhanced.
Get Skilled Suggestions Leave your Call facts, and our expert can get in touch with you to prepare an in depth commercial proposal. 70 alumina fire brick *Identify:
Selecting the ideal style of high alumina brick hinges on aligning alumina content material, specialized requirements, and Proportions with your operational requires. Regardless of whether you have to have standard T-three bricks for just a blast furnace or custom zirconia-enhanced units for any petrochemical plant, comprehension these components makes sure longevity and performance in high-temperature environments.
Increased physical power and abrasion resistance make phosphate-bonded brick compositions most well-liked in abrasive purposes, which includes pebble lime kiln feed ends and apps that aspect abrasive dust entrained inside a high-velocity gasoline stream.
Features of high alumina brick consist of great refractoriness, Price-powerful performance, high power, and abrasion resistance, resistance to acidic slags, and robust resistance to thermal shock. The Actual physical properties of high alumina brick refractories might be personalized to improve overall performance in specified purposes.
