A bell-type furnace is a type of heating equipment commonly used in industrial
production. Its working principle is to heat objects by placing the heating
element in a sealed furnace and using high-temperature heat generated by the
combustion of electric energy or gas.Process
Of Preventing Deformation And Cracking Of Mold By Vacuum Heat Treatment The
bell-type furnace is mainly composed of the furnace body, heating elements,
control system and furnace door. The furnace body is usually made of
high-temperature resistant materials, such as refractory bricks or refractory
fibers. The heating element can be a resistance wire, an electric heating tube
or a burner, and different heating elements are selected according to different
heating methods. Powder
metallurgy stainless steel vacuum sintering process The control system is
used to control parameters such as heating power, temperature and heating time
to ensure the stability and controllability of the heating process. The furnace
door is used to open and close the furnace to facilitate the loading, unloading
and maintenance of objects.Carburizing
process and carburized steel When working, the bell-type furnace first heats
the heating element to the set temperature, then places the object to be heated
in the furnace and closes the furnace door. The heating element begins to
transfer heat energy to the object, causing the object's temperature to
gradually increase. At the same time, the upper part of the furnace body is
usually equipped with a smoke exhaust port to discharge the exhaust gas and
smoke generated by combustion and keep the environment inside the furnace
clean.Effect
