Continuous gas shielded bright heat treatment electric furnace
Used for continuous production of martensitic stainless steel
through bright quenching, austenitic stainless steel through bright
annealing (solid solution) treatment, various copper materials and
copper alloys through intermediate recrystallization annealing,
final annealing, and stress relief treatment. The furnace design is
innovative, the structure is reasonable, energy-saving and high
thermal efficiency, the production quality is stable, and the use
is safe and convenient. Easy to operate, no industrial pollution.
The temperature control method is advanced, using intelligent
temperature control instruments, intelligent thyristors, and
Schneider electrical switches. Control accuracy ± 1 ° C. It is
progressiveness, reliable, practical and economical in industrial
furnaces. This equipment consists of transmission system, heating
system, cooling system, control system, and ammonia decomposition
gas supply system. The muffle furnace liner is made of imported
high-temperature resistant nickel alloy material, which is pressed
and welded together; Detachable electric heating element for up and
down heating; The steel belt conveyor has stepless speed
regulation, and the mixed gas of liquid ammonia decomposition
(hydrogen 75%, nitrogen 25%) enters the furnace to achieve gas
protection effect. The gas direction adjustment device ensures
stable atmosphere. After heat treatment by the equipment, the
surface of the product is bright and free of oxidation, and the
consistency of the treated product is good.
This furnace type uses heat-resistant stainless steel belts or
heat-resistant stainless steel mesh belts to transport workpieces
that require heat treatment, through the heating furnace and
cooling zone. Introduce inert gas or ammonia decomposition gas into
the furnace as a protective atmosphere to prevent and avoid
oxidation of the workpiece during heating and cooling processes. So
as to ensure that the surface of the stainless steel workpiece is
bright, free of oxidation and scratches.
The heating furnace (also known as the furnace liner or muffle
tube) is made of high-temperature resistant nickel alloy to ensure
that the workpiece is cooled to the required process temperature
when it is taken out of the furnace.
The continuous gas shielded bright annealing furnace adopts a
reasonable heating structure, with uniform furnace temperature,
smooth operation of workpieces on the conveyor belt, and minimal
deformation. The furnace size can be designed and manufactured
according to the specifications and production volume of different
products for users, with strong specificity and universality.
The biggest advantage of this furnace type
Widely applicable, suitable for continuous production such as
bright quenching, bright annealing (solid solution) treatment of
stainless steel, intermediate recrystallization annealing, final
annealing, and stress relief treatment of various copper materials
and copper alloys. Equipped with a strip winding mechanism, it is
suitable for bright annealing treatment in the cold rolling and
stretching industry of metal strips.
Advantages of this furnace type compared to vacuum furnace brazing
Not only is the cost low, but without vacuum furnace brazing,
product quality cannot be monitored at any time, and defects in the
production process cannot be changed. In addition, the operation
technology and process are not as complex and demanding as vacuum
furnaces, making it easy to operate and highly automated.
