Aluminum Extrusion Die Oven In Red Infrared Reflection
Infrared Extrusion Die Oven :
1,electricity saving
2,PLC control or temperature controller to control temperature
3, Sliding door or tilting open door or drawer type door
Above video shows 4500MT(12inch) aluminum profile extrusion plant working video, the infrared die oven is tilting opening door type.
Above photo shows 12inch infrared extrusion die oven with slidding open door
Two photoes shows drawer type aluminum extrusion die oven
How to choose the infrared die oven door openning type?
1,small extrusion die use drawer type aluminum extrusion die oven, such as 3inch,3.5inch,5inch and 6inch extrusion die; 7inch extrusion line also can consider drawer type if convenient to take dies. |
| 2, for big extrusion die, more than 8inch(including 8inch) extrusion line, use slidding type door open infrared extrusion die oven , or tilting type door open |
| 3, compare sliddign type and tilting type aluminum extrusion die oven, slidding type door open is more safe |
Infrared die oven working priciple:
1,Core working principle for aluminum extrusion die oven :
Belonging to radiation heating, non-contact, not relying on air convection for heat transfer, similar to heating objects with sunlight.
The electric heating element (infrared radiation tube/infrared radiation plate) is energized to convert electrical energy into medium/far infrared electromagnetic waves and emit them outward for infrared extrusion die oven
Infrared rays directly penetrate the air inside the furnace and irradiate the surface of the steel mold; The mold metal absorbs infrared light wave energy, causing the internal molecules to vibrate violently. The light energy is directly converted into heat energy, and the mold itself heats up.
The surface heat of the mold is then transferred to the interior of the mold through heat transfer, achieving overall heating.
The supporting infrared temperature measurement and temperature control system monitors the mold temperature in real time, controls the radiation power, and achieves constant temperature.
Key point: The air hardly absorbs infrared radiation, and the temperature of the air inside the furnace is not high. Most of the heat is given to the mold, so it is much more energy-efficient than traditional resistance wire convection furnaces. Traditional heating furnaces first heat the air in the furnace cavity, and then bake the mold with hot air, wasting a lot of heat on heating the air.
2,Main components of the equipment for infrared die oven:
Infrared radiation heating components (radiation plate, infrared heating tube)
Reflective layer: Concentrate scattered infrared reflections towards the mold to reduce losses
Infrared temperature probe
PLC temperature control system
Furnace body insulation shell
Infrared die oven advantage compare with traditional extrusion die oven:
| Item | infrared die oven | resistance die oven |
| heating method | infrared raidation heating die | first heating air,then heating extrusion die |
| heating speed | fast heating | slower heating |
| electricity consumption | save 30~50% more electricity | higher electricity consumption |
| die oxidation | heating shorter time,less oxidation | longer heating,more oxidation |
| outwall temperature | lower temperature | higher temperature |
