For heat treatment shaft furnaces are used in electrical or gas-heated versions. We supply shaft furnaces for various heat treatment processes up to usable lengths of over 10,000 mm and usable diameters of up to 5,000 mm.

The advantages: it is possible to charge the furnaces directly by crane. Due to the typical recessed furnace shafts only a low crane hook height is required. The vertical treatment of long components minimizes changes of dimensions and shapes. A high heating and cooling rate with a uniform heat transfer to the components is achieved by a convection using circulation and a gas cylinder.
