Specification of 1200~1500℃ 48%-75% Al2O3 Refractory High Alumina Bricks for Ceramic Kiln Firing Zone

These refractory high alumina blocks are produced the firing zone in ceramic kilns. They manage intense warm effectively. The temperature level range is 1200 to 1500 levels Celsius. That’s the best part of the kiln. The alumina content is important. It ranges from 48% to 75%. More alumina generally means far better performance versus warmth and chemical strike. This is essential in the shooting area.

The blocks are thick and solid. They have reduced porosity. This density quits warm from taking in way too much. It additionally shields against damage from gases and ash. The bricks resist damage. They maintain their shape under heavy tons at heats. This stability is essential for the kiln structure. The blocks won’t sag or split easily.

These blocks are difficult against chemical deterioration. Molten products and vapors in the kiln are extreme. High alumina blocks stand up to this strike. They last longer than other products. This decreases exactly how usually you require to fix the kiln. Much less downtime indicates far better production.

The physical properties are excellent. The bricks have a mass density around 2.5 to 2.8 grams per cubic centimeter. Their chilly squashing stamina is high, typically 40 to 70 Megapascals. This stamina sustains the kiln framework. The blocks are steady via duplicated home heating and cooling cycles. They do not expand or reduce way too much. This prevents gaps or splits creating.

Installation is straightforward. The bricks fit together well. Contractors use them like standard refractory forms. They develop a solid, trustworthy cellular lining. The lining shields the kiln shell. It makes certain even warmth distribution inside the shooting chamber. This aids make constant, premium ceramic products.

Utilizing these bricks makes kilns run much longer between shutdowns. They save cash on upkeep. The kiln runs a lot more successfully. The high alumina material is the main reason for this performance. It supplies the essential heat resistance and toughness.

Applications of 1200~1500℃ 48%-75% Al2O3 Refractory High Alumina Bricks for Ceramic Kiln Firing Zone

High alumina blocks function well in ceramic kiln firing areas. These areas encounter extreme heat. Temperatures often get to 1200 to 1500 levels Celsius. Ordinary materials fall short right here. Blocks with 48% to 75% alumina web content handle this intense warmth. They resist softening or flawing.

The shooting zone creates severe problems. Luster products evaporate at heats. These vapors assault the kiln lining. High alumina bricks supply solid chemical resistance. They hold up against rust from these hostile vapors. This keeps the kiln structure intact.

Thermal cycling is an additional significant challenge. Kilns warm up and cool often. This triggers stress in materials. High alumina blocks possess great thermal shock resistance. They manage these rapid temperature modifications well. This reduces fracturing and spalling.

Structural toughness issues considerably. Kilns are hefty frameworks. The blocks sustain considerable weight. High alumina qualities maintain high toughness also at peak temperatures. They withstand creep under lots. This protects against distortion of the kiln chamber.

The firing zone needs optimal stability. High alumina blocks supply reliable efficiency. They form a long lasting barrier versus warm and chemicals. This secures the external kiln structure. It guarantees constant shooting conditions for the ceramics.

Using these bricks extends kiln life. It decreases expensive downtime for repairs. Kiln drivers attain much better item top quality. Secure shooting conditions are vital for this. High alumina bricks provide that security.

5 FAQs of 1200~1500℃ 48%-75% Al2O3 Refractory High Alumina Bricks for Ceramic Kiln Firing Zone

People need high alumina bricks for ceramic kiln firing zones. They ask many questions. Here are five common ones.

What temperatures do these bricks handle? They work well from 1200°C to 1500°C. This covers most ceramic firing needs. The bricks stay strong and stable in this heat.

Why is the Al2O3 content important? Alumina makes the bricks resist heat. Higher alumina means better performance against very high temperatures. 48% to 75% Al2O3 gives a good balance. It offers strong heat resistance without being too costly. This range suits the firing zone’s demands.

Why use them specifically in the kiln firing zone? The firing zone gets the hottest. It faces the most stress. High alumina bricks handle this intense heat best. They protect the kiln structure. They ensure even, consistent firing of the ceramics. Other bricks might fail here.

Are these bricks resistant to thermal shock? Yes, they handle rapid temperature changes reasonably well. This matters because kilns heat up and cool down often. The bricks won’t crack easily from these cycles. Their structure helps them expand and contract safely.

Do they resist chemical attack? Yes, they offer good resistance. Glazes and fumes inside the kiln can be corrosive. High alumina bricks stand up to this chemical wear. They last longer than less resistant materials. This reduces downtime for repairs.
