ZG45 Cast Steel
A practical cast-steel option referenced by the original page; tempering and normalizing are used to balance strength and toughness.
Custom-engineered rolling rings transfer the full kiln load to the support rollers while helping the shell rotate smoothly and remain stable.


The kiln tyre, also called a rolling ring, carries the gravity of the kiln shell, refractory lining, internal devices and material, then transfers that load to the supporting rollers. Correct strength, toughness, geometry and surface condition are essential for smooth kiln rotation.
AGICO manufactures replacement rotary kiln tyre components against approved drawings and operating requirements. Material selection, heat treatment, machining allowances and inspection scope are confirmed before production so buyers receive a traceable part matched to the intended kiln position.
Values shown below preserve the original product information while identifying what must be confirmed for the actual order.

A practical cast-steel option referenced by the original page; tempering and normalizing are used to balance strength and toughness.
ZG35CrMo, ZG42CrMo and ZG45CrMo options can be evaluated for demanding load and service conditions against the buyer's specification.
Final grade, mechanical properties and heat treatment should follow the approved drawing and operating duty rather than a generic catalogue value.
Supports the rotating kiln shell through the tyre-and-roller system in dry- and wet-process cement lines.
Applicable where a heavy rotating shell requires a machined load ring designed for the actual duty.
Suitable for replacing cracked, worn or geometrically out-of-tolerance tyres after engineering verification.
Provide the kiln model, tyre position and equipment manufacturer.
Send the drawing or confirm outside diameter, inside diameter, face width and section profile.

The Kiln Tyre transmits or supports operating load through rotating and stationary interfaces. 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 Kiln Tyre from a name or model reference alone.
Provide the available values, drawing references and photographs for applied radial, axial and transient loads. AGICO will compare them with the proposed Kiln Tyre 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 diameters, fits, datums and bolt pattern. AGICO will compare them with the proposed Kiln Tyre configuration and identify any missing inputs before the manufacturing basis is released.
The production route for the Kiln Tyre is established after drawing review. It typically coordinates casting or forging route, heat treatment and rough 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 traceability and heat-treatment records; Critical journals, bores, faces and runout; Specified NDT at highly stressed transitions; Balance, contact pattern or assembly checks when applicable. 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 Kiln Tyre together with its mating parts and operating records. Typical reasons for closer inspection include:
Unusual vibration, noise or temperature near the component. 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.
Cracks, scoring, fretting or uneven contact marks. 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.
Loss of alignment, excessive runout or repeated seal failure. 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.
Dimension drift that prevents a controlled fit during shutdown. 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 Kiln Tyre 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.
Complete technical inputs reduce clarification cycles and help us quote the correct supply scope.
