Fluidized Bed Heat Treating.

Abstract:

Steel carbon, alloy, tool, and stainless, aluminum, titanium, and other metal can be heat treated economically in a fluidized bed furnace. All heat treatments except controlled rate cooling rate annealing are viable. Since gases are used to fluidize a bed of powder, any gaseous atmosphere can be used, and simply by turning a few valves, an atmosphere can be completely changed over in 2 minutes or less. This feature allows multiple heat treating operations to be done in the same furnace without cool down, switching furnaces, and reheating which is standard in commercial shops. Fluidized bed heat treating is economical, safer, and almost emission free. Data is presented comparing cycle times and cost for the most common heat treatments and results of emissions testing of fluidized beds are presented. Finally, fluidized bed heat treating cycles for steel, aluminum, titanium, magnesium, and copper are given.
