High-Chromium Heat-Resistant Steel
The original tip-plate material reference for resisting high temperature and protecting the shell at the kiln inlet or outlet.
Drawing-matched inlet and outlet tip plates, lamella seals and graphite block seals help protect the kiln end and control false-air or material leakage.


The rotary kiln inlet tip plate protects the inlet or outlet shell against burning, corrosion and deformation. Fan-shaped plates are bolted into a closed ring and used with refractory castable; radial gaps between adjacent plates accommodate thermal expansion.
A cement rotary kiln operates under negative pressure, so the sealing condition at both ends affects output, clinker quality and energy consumption. AGICO supplies individual wear parts or a coordinated sealing scope including lamella and graphite block sealing components.

The original tip-plate material reference for resisting high temperature and protecting the shell at the kiln inlet or outlet.
Fish-scale-like flexible plates accommodate rotation and movement while providing a maintainable high-temperature sealing interface.
Heat-resistant, corrosion-resistant and self-lubricating graphite blocks are used at the kiln head or tail and in selected lubrication interfaces.
Segmented tip plates protect the end of the shell and support the refractory castable arrangement.
Lamella or graphite systems help limit air, ash and material leakage around moving kiln ends.
Lamella sealing can also be applied to compatible rotating equipment after interface and temperature review.
Confirm kiln end, shell diameter and direction of rotation
Provide tip-plate segment drawing, bolt pattern and refractory interface
For lamella seals, provide stationary and rotating diameters plus movement envelope
For graphite seals, provide block profile, holder design, quantity and contact arrangement
Material verification for heat-resistant steel or graphite
Pattern, profile and bolt-hole dimensional inspection
Trial layout of segmented rings when specified
Surface and edge inspection for sealing contact
Clear identification of installation position and sequence
The Tip Plate and Sealing Parts forms a load-bearing or process-facing structure within cement and heavy industrial equipment. Its performance cannot be judged by outside dimensions alone. Load path, mating parts, operating environment and the condition of the surrounding equipment all affect whether a replacement will fit correctly and run reliably. AGICO therefore reviews the component as part of the machine rather than treating it as an isolated catalogue item.
For a replacement project, the most useful starting point is the current drawing together with the equipment model and site observations. Wear photographs, failure location, maintenance history and measurements taken during shutdown help distinguish normal consumption from an interface, alignment or operating problem. This review allows the quotation to state the proposed supply boundary and the information that still requires confirmation.
Confirming the following groups of data reduces dimensional risk and avoids selecting the Tip Plate and Sealing Parts from a name or model reference alone.
Provide the available values, drawing references and photographs for complete drawing, revision and critical dimensions. AGICO will compare them with the proposed Tip Plate and Sealing Parts configuration and identify any missing inputs before the manufacturing basis is released.
Where site data differs from an old drawing, mark the measured value and the measurement position. The final requirement should be agreed against the approved drawing rather than assumed from a nominal equipment designation.
Provide the available values, drawing references and photographs for mating interfaces, machining allowance and inspection scope. AGICO will compare them with the proposed Tip Plate and Sealing Parts configuration and identify any missing inputs before the manufacturing basis is released.
The production route for the Tip Plate and Sealing Parts is established after drawing review. It typically coordinates casting-process design, controlled melting and pouring, heat treatment and machining. Process hold points depend on material, geometry and the buyer's inspection requirements. Critical datums and machining references are identified early so that later operations protect the interfaces used during installation.
Inspection is planned around product risk rather than added only at final dispatch. Material chemistry and heat-treatment traceability; Casting surface and agreed NDT inspection; Machined datums, interfaces and overall dimensions; Final documentation, marking and release review. When a test or report is required, it should be listed in the enquiry so that sampling, acceptance criteria and document format can be agreed before manufacture. Final release checks also confirm marking, quantity, surface protection and the packing list.
Maintenance teams should evaluate the Tip Plate and Sealing Parts together with its mating parts and operating records. Typical reasons for closer inspection include:
Cracking, deformation or damage at loaded transitions. Record the location, extent and operating condition, then compare the finding with the equipment maker's limits and the site's maintenance procedure before deciding whether repair or replacement is appropriate.
Wear, erosion or loss of the required profile. Record the location, extent and operating condition, then compare the finding with the equipment maker's limits and the site's maintenance procedure before deciding whether repair or replacement is appropriate.
Misalignment or poor contact at a mating interface. Record the location, extent and operating condition, then compare the finding with the equipment maker's limits and the site's maintenance procedure before deciding whether repair or replacement is appropriate.
Repair history or dimensional loss that makes continued service uncertain. Record the location, extent and operating condition, then compare the finding with the equipment maker's limits and the site's maintenance procedure before deciding whether repair or replacement is appropriate.
AGICO can prepare a drawing-based Tip Plate and Sealing Parts for new supply or replacement service. The technical review covers the requested material, configuration, interfaces, inspection scope and documentation. If the original drawing is incomplete, provide measurements, nameplate information and clear photographs; the missing points will be listed for confirmation. No order-dependent dimension or performance value is treated as final until it appears in the approved technical documents.
Packing is planned for component weight, geometry, transport mode and destination. Finished surfaces can be protected against handling damage and corrosion, while loose accessories and documents are identified against the packing list. For international delivery, buyers should state the destination, preferred trade terms, lifting or site-access restrictions and required arrival schedule so that the quotation can separate manufacturing scope from freight and local handling.

It protects the kiln inlet or outlet shell from heat, corrosion and deformation and supports the refractory protection arrangement at the kiln end.
Lamella sealing uses overlapping flexible heat-resistant plates, while graphite sealing uses self-lubricating blocks held against the rotating interface.
The original design description specifies radial expansion gaps so adjacent fan-shaped plates can accommodate thermal expansion without squeezing and damage.
Yes. Send drawings, measurements and photographs so individual plates, lamella elements, graphite blocks or holders can be matched to the existing system.
