U-type cover plates and sealing covers protecting kiln inlet and outlet seals, ducts and high-temperature equipment. Cast in heat-resistant Cr-Ni alloy steel with accurate dimensions and flat sealing faces so the seal stays effective and gas leakage is minimised.

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.

Sealing faces that stay effective at temperature

False air entering a kiln or hot gas escaping a duct costs fuel and disturbs the process. Cover plates and sealing elements must stay flat and dimensionally stable in a hot, dusty environment, which is exactly what heat-resistant alloy castings with controlled flatness deliver.

Key features

  • Heat-resistant Cr-Ni cast steel for continuous high-temperature duty
  • Flat sealing faces machined or cast to specification
  • U, sleeve and segmented profiles to your drawing
  • Accurate bolt pitch for correct clamping and sealing pressure
  • Supplied with matching fasteners and gaskets on request

Materials

  • Cr25Ni20 type heat-resistant cast steel – best oxidation resistance
  • Cr-Ni-Mo heat-resistant grade – higher hot strength for larger covers
  • Heat-resistant ductile iron – lower temperature sealing duties

Applications

Kiln inlet and outlet seals, cooler and preheater connections, ducting seals and high-temperature equipment in cement, lime, metallurgical and power plants.

Why buyers choose Zhili

  • Reverse engineering from worn covers or sketches
  • Focus on flatness and fit, which is what makes a seal work
  • Batch quality verification with material certificates
  • Export packing that protects sealing faces in transit

Ordering and support

Send drawings, dimensions or worn covers. We confirm alloy, quantity and lead time, and advise on the most suitable profile for your seal arrangement.

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.
