IOB engineers and builds heat treatment furnaces type hood/bell furnaces for various purposes.

The hood/bell type furnaces can be used as:

                            · Heat treatment furnace for e.g. rod material and/or coils

                            · Heat treatment furnace for aluminum

                            · Annealing furnace under protective atmosphere

The hood furnaces are designed for operation with one or two loading/

annealing places.

The to be heat treated parts are placed directly or on grids onto the at the loading/annealing places arranged support benches by means of the charging machine/crane or fork lift .

The hood system is used in case of restricted availability of space.

The execution of the hood/bell furnace can be without or with door(s).

The loading/annealing place is very well accessible after the hood/bell has moved sideward for the loading or unloading process.

A very big advantage of the hood/bell construction is the excellent sealing of the hood towards the loading/annealing place.

Hence the execution as annealing furnace under protective atmosphere, using e.g. forming gas and/or endo gas, in the original execution or as option to be build in later is very well possible.
