_Retort Furnace

This type of furnace is used for the heat treatment of metals. It is particularly suitable for thermal processes that require a defined atmosphere such as nitriding, sintering, tempering, and soldering or preheating.

A retort furnace can be built as horizontal or as vertical apparatus. Equipped with a hermetically sealed retort, the workpiece to be treated can be heated without impairment by atmospheric oxygen or burner exhaust gas and its characteristics can be influenced by adding diverse gaseous or liquid elements, so that an optimal material structure is achieved. The heating functions electrically through a resistance heater or a gas burner.

The gas-tight retort of this type of furnace is made of high-temperature resistant steel. The workpieces are generally heated electrically by a resistance heater or by a gas burner. Retort furnaces are suitable for treating metals with processes which, as mentioned above, require a defined atmosphere, such as nitriding, sintering, tempering or soldering as well as for materials such as glass or ceramic and for annealing soft iron shot, which is used as munition in hunting.
