Bell-type furnace is a furnace type of that furnace body moves from a fixed bottom to up. Its base remains stationary. The furnace body moves up and down. This movement is provided with railed sledges.
Bell-type furnace provides ideal conditions for the heat treatment of stack samples (nut, bolt, etc.).
The products are placed in specially designed baskets according to process which is inside of the bell-type furnace. Fan system and environmental placed resistances provide a more homogeneous heat distribution in the furnace. Then, cylindrical retort closes and gas sweeping and vacuuming is done. (Retorts are preferred according to process type. It may not use in every bell-type furnace.)*
For the maximum life of the furnace and the longer use of the furnace equipment, we recommend that the heating rate of 10 °C/min should not exceeded. Flammable and explosive products must not be used in the furnace. Oily products mustn’t be put in the furnaces.
