stainless steel pipes bright annealing furnace

The stainless steel induction heating solid
solution bright annealing furnace is widely used
in a stainless steel welded pipe production
line,
In the manufacturing process of the stainless
steel pipe, the diameter of the pipe is Φ6 and
Φ273mm, which is suitable for stainless steel
SUS304, 316, 316L, etc. The online running speed
is adjustable from 0 to 10M/min, the heating
temperature is set according to the material of
the solution treatment, and the advanced
infrared temperature measuring automatic
detection system and the synchronous solution
refrigeration system are equipped with the
advantages of simple operation, multi-function,
multi-protection, multi-display, and integrated
self-contained water cooling system. need not be
equipped with external water cooling device.
The steel pipe is heated by all-solid-state IGBT
induction heating power supply, which has the
characteristics of small occupied area, light
weight, low working voltage, high safety factor,
low high-frequency radiation, low noise, low
failure rate, low maintenance difficulty, and
the like. The control system is controlled by
PLC imported from Germany. Large-screen display
made in Taiwan can be used to visually
understand the operation status and fault
condition of the equipment. The whole machine is
equipped with various protection measures to
greatly improve the stability and reliability of
the equipment and complete the interlocking
control and protection functions with the
production line.
The bright heat treatment process avoids the
environmental pollution caused by the
traditional pickling treatment process, and aims
at eliminating the structural defects of
stainless steel, reducing the hardness,
improving the performance of steel and restoring
the plastic deformation capability of the steel
to meet the processing requirements. The
induction heating power supply is used to heat
the stainless steel tube to the temperature
above its phase change temperature (austenitic
stainless steel generally does not exceed 1100
degrees centigrade) and then cool down after a
certain time. Generally for protective
atmosphere annealing, the purpose is to avoid
oxidation caused by the surface of the
regeneration of iron oxide scale, so commonly
known as bright annealing.
The bright continuous heat treatment furnace
mainly consists of a heating part and a cooling
part. In order to meet the requirements of
welding different pipes, an independent support
frame device is designed, on which heating and
quenching systems are installed. The support
frame can adjust the height of the center line
of the bright heat treatment device. The
quenching chamber connected to the sealing bush
of the heating coil is completely closed, and
the water is cooled on the outer surface, while
inside the tube, a conductive medium with high
heat conductivity rapidly transfers heat from
the stainless steel tube to the outer water
cooling chamber surface. The whole quenching
process is carried out under the control of the
protective atmosphere to ensure that the
brightness treatment can be continued before the
outlet temperature. At the same time, the
equipment adopts intelligent ignition system to
monitor the flame state at any time. Because the
furnace body adopts front and rear sealing and
the air path is reasonable, the bright reaction
is quick, the number of black pipes is reduced,
and the consumption of protective gas is greatly
saved for users. A heating sensor designed to
increase heating efficiency includes an
atmosphere sealing bush containing a
controllable protective gas for preventing
contamination from the external environment. The
direct water quenching device plays a very
important role in keeping the consistency of
product size. and the length of quenching is
kept to a very small extent.
