Atmosphere ReadyIndustrial Furnaces
IF-BF1 Bell-Type Annealing Furnace
Bell furnace for hydrogen or nitrogen atmosphere annealing of coils and wire.
The IF-BF1 bell-type furnace is the industry standard for bright annealing of steel wire, strip, and coil. A removable inner bell maintains the protective atmosphere while the outer furnace hood heats the charge; after soaking, the hood is removed and the inner bell remains until the batch cools below the oxidation threshold.
