Fluidised bed furnaces

Chennai-based Fluidtherm Technology, an ISO 9001 company, offers fluidised bed furnaces for quality heat treatment of H-11 and H-13 dies used for aluminium extrusion. Fluidised beds with their intrinsic temperature uniformity (?3?C) have the advantage of uniform heating ensuring a good microstructure and minimal distortion. As these materials require multiple tempering it is possible to couple the last tempering step with a nitrocarburising process resulting in a high surface hardness. The flexibility of the fluidised bed furnace, which operates at any temperature with any process gas, allows for a hardening furnace to double as a nitrocarburising furnace merely by changing the atmosphere. A uniform monophase compound layer backed by a diffusion zone provides for an extremely tough and hard nitrided surface. Additional advantages include fast heat up and cool down cycles, low investment and maintenance costs, zero pollution and a clean work environment.
