Specification of Porous 60% 70% 76% 80% Al2o3 Alumina Refractory Ceramic Roller with Open Both Ends

These ceramic rollers are made mainly from alumina. Alumina is light weight aluminum oxide. They are formed like tubes. Both ends are open openings. This is important. The vital function is their porosity. Porosity indicates little openings inside the product. We offer numerous porosity degrees. These are 60%, 70%, 76%, and 80%. The greater the number, the extra openings it has. Much more openings suggest the roller is lighter. It likewise lets gases travel through easier. This gas flow is commonly needed. It aids during high-temperature procedures. Alumina makes them extremely warm resistant. They take care of really warm conditions well. They remain strong under warm stress. This strength is important in kilns and heating systems. These rollers support items moving via the heat. The open ends enable special arrangements. Rods or shafts can experience them. This aids mount them safely. They are additionally simple to evaluate internally. Cleaning them is easier too. Their framework offers good thermal shock resistance. Unexpected temperature adjustments will not conveniently crack them. They last a very long time in hard environments. Common usages remain in ceramic kilns. They are used in tile production lines. Glass production uses them also. They operate in constant heating system procedures. Different porosity degrees match different needs. High porosity is good for gas launch. Reduced porosity might use even more toughness. Pick the level that fits your process best. These rollers are dependable transportation tools. They relocate products with extreme warm safely.

Applications of Porous 60% 70% 76% 80% Al2o3 Alumina Refractory Ceramic Roller with Open Both Ends

These porous alumina ceramic rollers are necessary parts for heat tasks. Individuals use them a great deal in kilns and heaters. The rollers are made from Al2O3 alumina. This material is extremely strong versus warm. It can handle really hot temperature levels without damaging. The rollers have open ends. This means air or gas can pass through the size of the roller. The permeable framework is essential. Porosity levels are 60%, 70%, 76%, and 80%. Higher porosity allows a lot more gas circulation via. This works for certain processes.

These rollers are common in ceramic and floor tile manufacturing facilities. They relocate items through the kiln during firing. The rollers support the weight. They also survive the extreme heat. The permeable layout aids manage the environment inside the kiln. Gas can move through the roller body. This assists create also heating. It protects against warm or cold spots. Uniform heating makes much better products. The rollers are also used in other high warm sectors. Metal treatment heaters utilize them. Glass annealing lehrs utilize them also. The rollers supply strong assistance. They last a long period of time also under challenging problems.

Different porosity levels suit various needs. A 60% porosity roller is much less open. It supplies good stamina and some gas circulation. It functions well for basic kiln use. A 70% porosity roller allows a lot more gas activity. It assists where much better environment control is required. The 76% and 80% rollers are much more porous. These are for tasks requiring optimal gas passage. They may be used in unique heat therapy actions. Selecting the ideal porosity relies on the process. The rollers are reputable components. They maintain production lines running smoothly. They are important for numerous producing tasks.

5 FAQs of Porous 60% 70% 76% 80% Al2o3 Alumina Refractory Ceramic Roller with Open Both Ends

What are these rollers made from? These rollers are made from alumina ceramic. Alumina is aluminum oxide. It is known for its strength and heat resistance. The rollers are porous. This means they have tiny holes inside. The holes help with heat flow. They also make the rollers lighter.

How hot can these rollers get? These rollers handle high temperatures well. The exact temperature depends on the alumina percentage. Rollers with 60% alumina can handle around 1200-1300°C. Rollers with 70% handle about 1400-1500°C. Rollers with 76% and 80% alumina handle even higher heat, maybe 1500-1600°C or more. Always check the specific product details.

What do 60%, 70%, 76%, 80% mean? These numbers show the amount of alumina in the roller. A 60% roller is 60% alumina. The rest is other ceramic materials. Higher alumina means better heat resistance. Higher alumina often means higher density too. But higher density might mean less porosity. It’s a balance.

Why are both ends open? The open ends are important. They let hot air or gases pass through the roller. This helps heat spread evenly inside a kiln or furnace. It prevents hot spots. It also makes the roller lighter. This reduces stress on the roller supports.

Where are these rollers used? You find these rollers in high-heat industrial settings. They are common in kilns for firing ceramics, tiles, or glass. They are used in furnace conveyor systems. The rollers support products moving through the heat. The specific alumina percentage chosen depends on the needed temperature and application.
