The WEBBCO FLEX-STEEL™ Kiln Seal is 100% metal, which enables it to be used effectively in high temperature applications, such as high-temperature rotary kilns and calciners used in:

• Cement making
• Papermaking (lime recovery in pulp mills)
• Iron ore pelletizing
• Lime production
• Drying of bulk granular materials
• Specialty pyroprocessing
• Hazardous waste destruction
• Asphalt
• Chemicals
• Fertilizers
• Petrochemicals

Features

• Easy installation and replacement
• Meets environmental compliance requirements.
• Can be customized for any application or configuration.
• Can be retrofitted to any rotary calciner, cooler, dryer or kiln, regardless of original equipment manufacturer (OEM).
• Available in various alloy combinations, based upon application and operating conditions.
• Made of heat-resistant materials that contain NO asbestos or refractory fibers.
• Adjusts automatically to most shell runouts.
• Overlapping plates made of stainless steel spring stock.
• Sealing edge of each plate fitted with a wear shoe .
• Kiln seal shoes made self-lubricating due to presence of graphite granules. Shoes prevent leaves from rubbing against the kiln shell, eliminating the probability of grooving.
• Shoes lock overlapping plates together, keeping out air along the entire overlap zone.
• Metal wear bands can be installed onto the shell's riding surface to minimize degeneration of "wear shoes."
• Heat-resistant springs withstand higher temperatures and axial movements with maximum effectiveness.
• Available 45° to the shell axis, which provides a more neutral or "relaxed" position that accommodates a greater amount of radial movement or "run-out" during operation.

Lubrication
Initially, the shoes are to be coated with a high-temperature lubricant furnished with the seal. After break-in, molybdenum disulfide lubricants may be used to extend the life of the shoes.

Special Considerations
Please advise if the application includes:

• Corrosive gases or liquids
• Explosive vapors
• Positive hood pressures
