Specifications of Over 1200C 95% 99% Al2O3 Alumina Ceramic Roller For Roller Kiln

Below are the specs for our high-temperature alumina ceramic rollers. These rollers are created roller kilns. They stand up to temperature levels over 1200 ° C. They can be found in two major grades: 95% Al2O3 and 99% Al2O3. This implies the primary material is alumina. The number shows how pure it is.

The 95% Al2O3 rollers are very strong. They use exceptional warm resistance. They are cost-efficient for several uses. The 99% Al2O3 rollers are even purer. They give exceptional performance. They withstand put on far better. They take care of extreme heat better too. Both grades are dense. Their density is typically 3.6 to 3.9 g/cm TWO. This thickness assists them last lengthy.

These rollers are really hard. They withstand abrasion well. This means they do not wear down swiftly. They maintain their form under high warm. This is vital for kiln security. They have low thermal expansion. They won’t split easily during temperature modifications. They offer great chemical security. Many chemicals won’t harm them. This is essential in harsh kiln problems.

The surface area coating is really smooth. This minimizes friction. Products move smoothly via the kiln. The rollers are precision-made. They make sure regular rotation. This brings about uniform item shooting. They help in reducing power usage. Efficient rollers imply reduced operating expense.

These alumina rollers are optimal for firing ceramics. They work well for floor tiles. They are best for sanitaryware. They manage technical porcelains. They are crucial in high-temperature roller kilns. They replace steel rollers. Metal rollers typically fall short at these temperatures. Our rollers last much longer. This lowers substitutes. This conserves money in time.

Select the quality based on your requirements. The 95% Al2O3 is great for the majority of applications. The 99% Al2O3 is best for the toughest jobs. Both ensure dependable kiln procedure. They handle the heat. They ensure quality manufacturing.

Applications of Over 1200C 95% 99% Al2O3 Alumina Ceramic Roller For Roller Kiln

Roller kilns need reliable parts. These alumina ceramic rollers deliver. They contain over 95% or 99% Al2O3. This high purity is critical. It lets them handle extreme heat. They work continuously above 1200°C. This temperature is common in firing ceramics, tiles, and technical materials. Ordinary materials fail here. These rollers stay strong.

Heat resistance is their main job. They manage the intense kiln environment. Products move smoothly on them. The firing process stays consistent. High purity alumina also fights wear. Rollers face constant friction and heavy loads. They resist abrasion well. This means they last much longer. You replace them less often. This saves money and downtime.

Chemical stability is another big plus. Alumina is inert. It doesn’t react with glazes, fumes, or materials in the kiln. This avoids contamination. Your fired products stay clean. Product quality remains high. No unwanted marks or defects happen.

Thermal shock resistance is vital too. Kilns heat up and cool down. Temperature changes can be fast. This stresses materials. Alumina ceramic handles these sudden shifts. It doesn’t crack easily. This reliability keeps your kiln running. Production halts are minimized.

5 FAQs of Over 1200C 95% 99% Al2O3 Alumina Ceramic Roller For Roller Kiln

Here are five common questions about our high-temperature alumina ceramic rollers:

What exactly are these rollers?
These are industrial rollers made mainly from aluminum oxide. They contain either 95% or 99% pure Al2O3. They are designed for roller kilns. They carry products through high-heat processes.

Why is the ‘Over 1200°C’ rating important?
Kilns operate at extreme temperatures. Ordinary rollers fail or warp under that heat. Our rollers withstand temperatures above 1200°C reliably. This ensures stable kiln operation. Production keeps running smoothly.

What’s the difference between 95% and 99% Al2O3?
The number shows the alumina purity level. 99% alumina is denser. It handles heat better. It resists wear longer. It is stronger. 95% alumina is a cost-effective option. It still performs well for many uses. Choose based on kiln needs and budget.

How do these rollers last longer than metal ones?
Metal rollers oxidize and deform in intense heat. Alumina ceramic resists oxidation. It keeps its shape. It doesn’t soften. This reduces roller replacement frequency. It lowers maintenance costs. It cuts downtime.

Do these rollers need special care?
They are very durable. Basic handling is important. Avoid hard impacts during installation. Keep surfaces clean from heavy buildup. Check rollers periodically for wear. Their lifespan is generally long under proper kiln conditions.
