Features of Kerui Silicon Carbide Beam

• High Thermal Resistance: Silicon carbide beams can withstand temperatures of up to 1600°C (2900°F) without undergoing any significant deformation, ensuring stable performance under extreme heat.

• Excellent Mechanical Strength: These beams exhibit outstanding flexural strength, capable of supporting heavy loads without compromising structural integrity, which is essential in supporting large kiln structures or heavy refractory linings.

• Thermal Shock Resistance: SiC beams are highly resistant to rapid temperature changes, reducing the likelihood of cracking or failure during heating and cooling cycles.

• Corrosion Resistance: SiC’s excellent resistance to both acidic and alkaline environments ensures the longevity of the beam even in corrosive atmospheres or environments exposed to molten metals or slags.

• Long Service Life: These beams are designed to last in continuous or harsh conditions, offering a cost-effective solution in industrial applications with a low maintenance requirement.

Main Uses of Kerui Silicon Carbide Beam
