Top hat aluminising furnace for aircraft components

• Supplied with 2 working hearths plus parking hearths for the retort and a separate parking hearth for the furnace
• The furnace incorporates the control within its framework, thus eliminating trailing cables
• A manually controlled overhead hoist transfers the furnace and retorts to their respective positions
• Fully compliant with international aerospace standards
• Designed to operate up to 1100C under both hydrogen and inert atmospheres
• Power rating of 150kW - controlled over 3 zones with gas system controlled by PLC programmable logic
  

Top hat furnace for annealing molybdenum sheets

• Top hat with retort, hoist and nitrogen/hydrogen atmosphere
• Maximum temperature: 1000C (900C inside retort)
• The furnace is rated to heat a maximum charge of 360kg of sheets, plus their support trays in the inconel retort to temperatures up to 900C under atmosphere
• A full hydrogen/nitrogen gas safety system is provided to ensure nitrogen purge up to 750C and change over to hydrogen gas for continuation of the process up to 900C, reverting to nitrogen during cooling from 750C
• Maximum power: 75kW
  

Atmosphere top hat furnace

• For processing relay components
• Maximum operating temperature: 1150C
• Temperature uniformity: +5C between 900C - 1150C
• Usable retort volume: 0.4m
• Spiral wire elements on 4 sides of chamber
• Maximum power: 72kW
  

Top hat furnace for mould firing

• Designed as part of an ongoing project to increase the use of aluminium alloy castings by the aerospace industry
• Chamber dimensions : 1000mm x 1000mm x 1000mm
• Maximum charge weight : 450kg
• Free radiating resistance wire elements all four sides of the furnace
• As the furnace is

   

  used for both lost wax and plaster moulds, the equipment has to accommodate a wide range of operating temperatures : plaster block moulds (which can weigh up to 200kg) are typically dried at 270C for up to 70 hours before being filled
• Ceramic shell moulds are also processed at low temperatures for burn off residual wax - they are then sintered at 1050C
• Maximum power : 60kW
• Controls located in a separate console
