10- Wire Electric Heat Treat Furnace Continuous SS Wire Anneaing CE Certified


10-wire Electric Heat Treat / Treatment Furnace Continuous SS Wire Anneaing


1. Construction heat treat/ treatment furnace /steel wire annealing furnace

Continuous steel wire annealing furnace is mainly composed of furnace body, stainless steel pipe, heating

elements and fixing devices, electrical control system, and furnace temperature automatic control system.

furnace body

1.1 Furnace shell:heat treat/ treatment furnace /steel wire annealing furnace

The outer wall of the furnace welded with Q235 plate with the thickness of 3 mm.

It welded by 10 # section steel and 8 # section steel. The furnace has the advantage of firm

structure, reliable and durable performance.

1.2 Furnace lining: heat treat/ treatment furnace /steel wire annealing furnace

The furnace lining is all-fiber structure. It adopts high-quality high-temperature refractory

fibers, standard stainless steel round parts and scientific and reasonable mounting method.

The aluminum fibers are pre-compressed into blocks (compression gravity: ≥230Kg/m3 ) and

then fixed to the furnace body by round stainless steel parts. The installation thickness of the

insulation material is ≮350mm. The structure has low heat conductivity, strong anti-shock capacity, and anti-erosion.

The aluminum silicate fiber resists a maximum temperature of 1200℃. The material of round steel is 1Cr13 round steel.

The lining has the effect of rapid heating and heat preservation.

The bottom is made of heavy refractory brick and mullite brick.

The expansion joints of refractory bricks are retained in masonry to

prevent the expansion damage of lining when heated. Every 400 mm,

a shaped brick is used to fix stainless steel pipes (the wire mesh

inside the shaped brick prevents the cracking of the shaped brick

leading to the deformation of the stainless steel pipes). The two sides

of each shaped brick are fixed with stainless steel splints.

1.3 Furnace body heating element:


The heat treatment furnace employs high-quality high-resistance alloy material 0Cr27AL7Mo2 which is

processed into corrugated resistance bands. They are installed on the bottom of the furnace

body to ensure that they are not damaged during processing. The furnace has 6 heating zones.

The arrangement of heating elements corresponds to that of heating zones. An independent

heating group is arranged in each heating zone. All lead-out rods are made of φ16 0Cr25AL5

material. The special industrial chucks are used for lead-out rods to ensure firm and reliable wiring.

1.4 Heating elements

The heating elements adopt high quality high temperature alloy belt in order to meet long term

use at the temperature of 1100 ℃. The furnace lining adopts aluminum silicate refractory fiber.

The furnace is equipped with 10 stainless steel tubes for wires going through. The specification

of the tube is Ø22, 12 meters length. The tube material is 310S(Cr25Ni20Si2)which has

the advantage of durability at high temperatures. Each pipeline is equipped with protective

gas joint. The cooling groove at the pipe outlet is provided with a sealing connecting device.

The inlet is equipped with guide device to ensure that the wire runs in a straight line in the

pipeline. And the thermal expansion device of the pipeline is also equipped in the furnace.

1.5 Cooling tank

The cooling tank is made of 5 mm thick iron plate by pressing and welding, and the frame

is welded with 10# and 8# Q235 steel. There are 10 stianless steel tubes sealed and welded

with heating tubes. The stainless steel tube material is 304 (1Cr18Ni9), and the diameter

is Ø22. The tank is equipped with inlet and outlet water to ensure rapid cooling of annealed parts.

The effective cooling pipe length is 5.5 meters.

1.6 Ammonia decomposition device

The furnace has ammonia decomposition and purification device. Using liquid ammonia as raw

material, under the action of catalyst, heating decomposition to obtain hydrogen and nitrogen

mixed gas containing 75% hydrogen and 25% nitrogen.

1.7 Temperature control system

Temperature control: the furnace adopts Shanghai Guolong intelligent temperature controller

to control the temperature which has self-tuning function to calculate the ideal PID parameter

and achieve temperature stability. The temperature controller has the functions of over-temperature

alarm and thermal couple breakage protection.

The heating loop adopts the SCR and trigger control. The output heating power can be changed to

achieve temperature control.

The over-temperature alarm system is sound and light alarm which ensures the safety of workpieces

and equipment in furnace.

All main control devices, such as AC contactors, fast fuses, intermediate relays, stroke switches,

operation switches, buttons, signal indicators, and operation and display devices are the brand of
