box resistance furnace :the thermal refining, heating, tempering,
and annealing of large size carbon steel and alloy steel parts
box resistance furnace-
- This equipment is mainly used for the thermal refining, heating,
tempering, and annealing of large size carbon steel and alloy steel
parts, for tempering of the surface annealed parts, as well as for
the stress reducing and annealing of welding parts.
1)-all-fiber lining; good heating holding property;
2)-fast burner, air-fuel gas automatic proportioning adjustment,
impulse burning, time sequal control;
3)--efficient recycling of the heat
4)-automatic programmable control of temperature rising, holding,
and temperature dropping.
5)-Upper industrial computer whole-process monitoring.
-All fiber lining; complete sealing of the furnace body, automatic
control over each medium; automatic control of the furnace
pressure, imported or domestic burner; PLC distributed control
-Application: annealing treatment of metal workpieces or forge
pieces at rolling mills.
- Rated temperature: 700——1100 ±10 degree celcius, control
accuracy:less than ±1 degree celcius.
- In strict accordance with the environmental requirement of the
state. It has met the environmental requirement for special type
- Its firing control system is equipped with imported or domestic
quality high speed burner with ejecting speed of 100s/m.
- The furnace door is opened up-down or moved right-left. The upper
cross arm of the furnace door is equipped with worm reducing gear,
double chain wheel, plate chain, and gantry support balance block
structure. Also a double up-down whole fiber guiding rail sloping
block presses hard on the furnace door.
- The bogie driving is made through the self-moving mechanism of
shield gear type or bevel wheel type. The bogie and the furnace
body are sealed through electrical or pneumatic pressurizing
- The furnace is one light framework. The annealing furnace is made
of quality whole fiber lining, and the forging heating furnace of
combined zirconium fiber lining. It has the advantages of light
weight, good heat insulation and temperature rise of the outer wall
of the furnace body less than 50 degree celcius.
- -The air pre-heating device preheats the heat recycling device. The
furnace pressure is regulated through pressure transmitter and
smart meter. The valves are controlled automatically and fire is
controlled automatically. Its emission of fume meets the state
- Temperature control method: 3 methods, including upper industrial
computer distributive control; imported smart temperature control
instrument; Siemens PLC control and manual control.
