Bell Type Dia 1500 Height 2000mm Annealing Heat Treatment Furnace
1.Application of Electric Heat Treat Furnace heat treat furnace
The strong convection bell type heat treatment furnace is a batch
type resistance furnace, which can be operated continuously with
multiple furnaces. It is mainly used for heat treatment of machine
parts such as coil wires and wires, and can also be used for heat
treatment of other workpieces under the environment below the rated
temperature. The electric heat treat furnace has good thermal cycle
and uniform temperature. The temperature control system uses PID
zero crossing trigger thyristor, and Shanghai Guolong programmable
high precision intelligent meter to control temperature. The
furnace has good stability, and uses paperless recorder to
automatically record temperature, with U disk recording and over
temperature alarm dual control, to ensure that the workpiece does
not exceed the temperature. Automatic interlock control is adopted
for each mechanical transmission part of electric bell type furnace
to ensure operation safety.
