Inner cylinders and barrels for cyclone preheater stages, cast in heat-resistant Cr-Ni alloy steel with controlled circularity, wall thickness and joint faces. Zhili supplies these parts in segmented form so they can be installed inside the vessel and aligned accurately.

If you need detailed technical information, drawings or a price for a size we have not listed, please email us at cnwearparts@lyzhili.com — we are a customized factory for crusher and mill wear parts and we quote quickly.

Cyclone internals that survive thermal cycling

The inner cylinder guides gas and material inside the cyclone, and it runs hot, erosive and under constant thermal cycling. Cracks and distortion there break the separation efficiency of the whole stage. Zhili casts inner cylinders with controlled wall thickness and circularity in alloys selected for the operating temperature.

Key features

  • Heat-resistant Cr-Ni alloy cast steel for high-temperature service
  • Circularity and wall thickness checked to keep the gas path uniform
  • Segmented design for access and accurate alignment inside the vessel
  • Joint faces machined so segments assemble without steps
  • Matching support brackets, anchors and fasteners available

Materials

  • Cr25Ni20 type heat-resistant cast steel – oxidation resistance at high temperature
  • Cr-Ni-Mo heat-resistant grade – higher hot strength where needed
  • Abrasion-resistant overlay – for stages with heavy dust loading

Applications

Cyclone preheater stages and calciner vessels in cement and lime plants, alumina calciners, and high-temperature dust separation vessels in metallurgy and power generation.

Why buyers choose Zhili

  • Reverse engineering from worn cylinders or existing drawings
  • Careful dimensional control for inside-vessel assembly
  • Consistent heat-resistant casting quality, verified per batch
  • Grouped shipment with other preheater spares to cut freight cost

Ordering and support

Send the stage details, drawings or worn parts. Our engineers confirm alloy, segment sizes and lead time, and can review your installation sequence.

Customized Solutions

Customized according to your operating conditions

High-wear working conditions

For highly abrasive materials such as limestone and sandstone, we adopt high-chromium cast iron or ceramic composite materials, which extend the service life by 3 to 5 times.

High-impact working conditions

For high-impact materials like construction waste and metal ores, we adopt a reinforced structure with high manganese steel and alloy bars, delivering excellent impact resistance.

High-temperature working conditions

For high-temperature materials including cement clinker and slag, special heat treatment is adopted to retain hardness and wear resistance at elevated temperatures.
