What are the main factors affecting the life of infrared tunnel furnace lamps?

Theinfrared tunnel furnace is used for industrial baking. The temperatureof the infrared tube is normally used within 200 degrees. What factorswill cause the short life of the infrared tunnel furnace tube? Let's talk about it with Huiyue Li S. Please pay attention to the tunnel furnace with more relevant information.

Oh, voltage
A, pipe wall load. The load lamp has a low life, the same working current, and the lamp has a small diameter and a low life.
B, working voltage. The lamp voltage is high and the service life is low.
C, power density. High power density lamp life is low.
   
Second, the material
  The quality of the quartz glass on the pipe wall has a great influence on the life of the infrared lamp. Good quartz glass has high purity, no bubbles inside, and a smooth surface. Becausethe temperature of the pipe wall is above 800 °C, if the purity is notenough, there will be gasification of the glass surface, which willproduce many tiny pits, which will affect the ultraviolet radiation outof the pipe wall. Thedomestic quartz tube can be visually seen with bubbles in the tubewall, which affects the ultraviolet radiation from the tube wall. Theair bubbles will form a high-pressure air mass explosion at hightemperature to break the tube wall. Theelectrode material is generally a surface of a tungsten wire that isfired with a tantalum layer of zirconate or other cathode emittingmaterial. The agingresistance and temperature resistance of tungsten wire and cathodematerials directly affect the life of the electrode.
