Specifications of High Temperature Alumina Ceramic Roller For Glass Tempering Furnace

Our high temperature alumina ceramic rollers deal with glass tempering heater conditions. These rollers are constructed difficult. They use premium alumina product. The alumina pureness is very high, typically ≥ 99%. This pureness gives excellent resistance to warmth. They endure temperature levels up to 800 ° C easily. Some grades take care of also 1000 ° C temporary. Thermal shock resistance is solid. Sudden temperature adjustments won’t fracture them. This is critical for heating system start-up and shutdown.

The surface is really hard and thick. Vickers solidity surpasses Hv 1500. This hardness protects against surface wear. Glass gliding over the roller causes marginal damages. The smooth surface area coating matters too. Surface roughness Ra is ≤ 0.4 µm. This level of smoothness protects against marking the warm glass surface area. You obtain tidy, scratch-free toughened up glass.

Dimensional accuracy is accurate. Roller straightness is tightly controlled. Runout resistance is marginal. This ensures smooth glass transportation. Wobble or resonance is eliminated. Rollers run real. Criterion sizes vary from 40mm to 120mm. Sizes increase to 4500mm. Customized sizes are feasible. We maker them to your specific heater requirements.

Mechanical strength is high. Flexural strength procedures ≥ 300MPa. This stamina supports heavy glass loads. The rollers won’t bend or droop under weight. Chemical security is another plus. Alumina stands up to oxidation and corrosion. Heating system environments do not weaken it. Alkali vapors from the glass process reason no injury. Long service life results. These rollers need replacing much less commonly. They save downtime and upkeep costs.

Applications of High Temperature Alumina Ceramic Roller For Glass Tempering Furnace

Heat alumina ceramic rollers are crucial parts in glass tempering heating systems. These rollers lug the glass sheets through the extreme heating and fast cooling stages. The process needs extremely challenging materials. Alumina ceramic handles this work completely.

These rollers encounter extreme heat. Glass tempering requires temperature levels near 700 levels Celsius. Regular steel rollers would certainly sag or thaw. Alumina ceramic keeps strong at these temperature levels. It keeps its form well. This security is critical for keeping the glass flat during toughening up.

Thermal shock resistance is another significant advantage. The rollers warm up quick when the heating system starts. They cool down quickly when production stops. Alumina ceramic takes care of these abrupt temperature level changes without breaking. This sturdiness indicates fewer breakdowns. Heating system downtime is decreased. Production stays effective.

Surface top quality matters a great deal. The rollers touch the warm glass straight. Any kind of roughness or issue on the roller surface can mark the glass. Alumina ceramic rollers are extremely smooth. They supply an excellent, regular contact surface. This ensures the final tempered glass is remarkable.

Reduced thermal growth is an essential residential property. Alumina ceramic barely expands when warmed. Rollers stay right and lined up. This avoids glass distortion. The glass moves smoothly via the heating system. Constant high quality is preserved.

Chemical inertness is likewise essential. Furnace environments can be severe. Alumina ceramic stands up to deterioration from gases or vapors. The rollers last much longer. They don’t launch pollutants onto the glass surface area.

These rollers are utilized in all constant tempering lines. They work in straight heating systems lugging huge glass sheets. They additionally work in vertical heaters directing glass panels. Their dependability supports high-volume manufacturing. They are vital for making solid, safe tempered glass for structures and vehicles.

5 FAQs of High Temperature Alumina Ceramic Roller For Glass Tempering Furnace

What material makes these rollers so heat-resistant?
Alumina ceramic is the key. It handles extreme furnace temperatures easily. This material won’t melt or warp like metal rollers might. It keeps its shape and strength under intense heat.

How hot can these rollers actually handle?
These rollers work reliably up to 1600°C (2912°F). That’s much hotter than standard rollers. Glass tempering furnaces run very hot. These rollers are built for that environment. They won’t soften or fail prematurely.

Why is the roller surface so smooth?
A super-smooth surface prevents marking the hot glass. Glass sheets slide over the rollers during tempering. Any roughness could scratch the surface. Our rollers ensure a flawless glass finish. Quality control checks every roller.

How long do alumina ceramic rollers last?
They last significantly longer than other types. Expect years of dependable service. Alumina ceramic resists wear and corrosion. It handles sudden temperature changes well. This durability means less downtime and lower costs.

Can you get custom roller sizes?
Yes, custom sizes and specifications are available. Different furnaces need different roller dimensions. We work with your exact furnace specs. Tell us the length, diameter, and other requirements. We produce rollers to fit your machine perfectly.
