Furnace Design & Build - A range of designs

Designed specifically for the pre and post-weld heat treatment of gas turbine nozzle segments. The furnace has an electrically driven door which also retracts the chamber hearth for ease of loading. The working vacuum is 10-4mbar with an operating temperature of 1200°C. A rotating door ring allows forced gas quenching at 2bar overpressure. Charge size is 850mm x 850mm x 1100mm long with internals consisting of expanded graphite insulation with CFC heaters.

Multi-functional Vacuum Sintering Furnace for development of stainless-steel components. Capable of 1800°C with a 10-5mbar working vacuum range, molybdenum internals and a 5bar PID controlled gas quench system. The horizontal front-loading chamber was designed to accept a 250mm x 250mm x 350mm deep charge. This furnace is able to work in a variety of modes i.e. under vacuum, argon, hydrogen and controlled partial pressure atmospheres. 

This controlled atmosphere furnace was designed to process gas turbine nozzles at temperatures up to 1200°C. A ceramic fibre lined heating mantle radiates on to an Inconel bell jar which in turn radiates on to the product. The charge can be up to 2m diameter x 1.2m high and weigh up to 500kg. To achieve the required cooling times for the material concerned a cooling hood replaces the heating mantle during the quenching cycle.
