SEALED QUENCH FURNACES

PROCESS CAPABILITIES

  • Case Carburising

  • Carbonitriding

  • Neutral Hardening

  • Carbon Restoration

  • Nitrocarburising

  • Normalising

  • Annealing

 

 

 

Superior Thermal Performance

The circular cross section of the furnace has a larger internal heat emitting surface area which allows quicker load recovery and a lower shell surface area that reduces wall losses.

Superior Temperature And Atmosphere Distribution

The circular design also eliminates eddies which would be caused by sharp corners and allows effective and uniform atmosphere circulation around and beneath the work basket ensuring uniform temperature and stable atmosphere conditions.

 

Design For Endurance

 

Carefully considered circuitry part specification, manufacturing method and acceptance criteria ensures long trouble free performance.

 

 

 

EQUIPMENT FEATURES

  • Insulation: low thermal mass fibre insulation for rapid and uniform temperature recovery and atmosphere conditioning.

  • Atmosphere Circulation Fan: high alloy, rugged long life design, bung mounted.

  • Heating System: radiant tubes with bayonet electrical elements, gas or oil firing.

  • Vestibule Sealing: self adjusting positive sealing door with a supervised pilot and flame curtain.

  • Improved Productivity: reduced cycle times, higher productivity and lower operating costs.

  • Atmosphere Control: CO/CH4/CO2 analyser, Oxygen probe.

  • Effective Quenching: bi-directional, variable flow through propeller pumps within draft tubes and CFD designed baffle system ensure consistent hardness and reduced distortion.

  • Cooling & Reheating: upper deck with atmosphere circulation for cooling the work basket in protective atmosphere. The system design allows cooling prior to reheating the same work basket.
