I. Main technical parameters of infrared heating tunnel furnace for automotive interior panel

1, inner tank size: heating zone length 5.0 meters (divided into three temperature zone control)* net height 0.1 meters * inner width 2.0 meters;

2, overall size (approx.) : total length 7.6 meters * Height 1.5 meters * width 2.3 meters; The conveying surface is 0.84m ± 0.025m above the ground adjustable; Feed area 2 meters, heating section 5 meters (divided into three sections), discharge area 0.6 meters;

3, temperature range: room temperature ~ +300℃;

4, shell temperature: the temperature does not exceed the environment +10℃.

5, circulation air mode: front and back to the middle hot air circulation;

6, power supply: three-phase five-wire system, 380V, 50HZ;

7, power: total power 110KW;

Second, automotive interior panel infrared heating tunnel furnace structure characteristics

1, shell material: 1.5㎜ cold plate bending, surface phosphating, paint treatment, corrosion resistance and easy to clean.

2. Inner liner material: 1.4mm thick SUS304 stainless steel plate; Keep the inner liner clean and dust-free, rust and corrosion resistant;

3, the bottom frame of the furnace body: 50*50*2.0mm square pass production; Maintaining the bearing strength of each surface inside and outside the furnace body, and retaining the coefficient of thermal expansion and cold contraction, can prevent the deformation of the furnace body.

4, conveyor belt: stainless steel wire mesh conveyor belt: mesh is 10*50mm, wire diameter: 1.5mm;

5, hanging ring: the top four corners of the furnace body is equipped with four rings, easy to load and unload goods;

Third, automotive interior panel infrared hot wire tunnel furnace function

1, overtemperature alarm: when the actual detection temperature exceeds the overtemperature protection thermostat set value, automatically cut off the heating power supply, play a double protection function;

2, sound and light alarm: alarm light with buzzer.

3, power supply phase, phase sequence protection: equipped with a phase sequence protector, can prevent the fan and motor reversal;
