BELL ANNEALING FURNACE
Continuous types of
Vison make Furnaces are available for Bell Annealing of wire, Tubular
Radiators and pipes made up of high grade steels with bright annealing,
the cold hardening from the previous rolling or drawing is eliminated.
The annealing material is pulled and/or pushed through the furnace without
any transport devices. The annealing and cooling channel consists
of numerous pipes, which are arranged close to each other. The exist openings
of the cooling pipes are sealed to the annealing material by means of
elastic rings. The cooling and annealing pipes are always kept under
an inert gas atmosphere.
Heating is carried out by electric resistance elements, which are embedded
in insulating blocks made up of ceramic fibres. The low consumption
of inert gas and heating energy is a special future of Vison Bell Annealing
Furnaces. The heating up time of the Annealing Furnace from 20°C
to 1100°C is less than one hour.
