The heating tube of the electric oven is very important. The function of the oven is to produce high heat to bake or dry things. Commonly used heating devices for electric ovens include "stainless steel heating tube", "resistance wire (electric heating wire) row heater", and "quartz heating tube". Among them, stainless steel heating tube has the highest efficiency and is relatively convenient to replace and maintain. . The other two have been used before, but now they are relatively rare, and the efficiency is not as high as the first. Let's take a look at the advantages of the three electric heating tubes.
Which is better, quartz heating tube or stainless steel heating tube?
Quartz tube heating generally uses radiation to heat the object. The heating is more uniform and does not touch the heated object, but it is difficult to heat the local area; while the stainless steel heating tube is heated by heat conduction, heating is fast and not easy to be uniform, but it can be locally heated.
Quartz tube can be said to generate heat quickly, but its temperature drops quickly when the power is cut off, the life of the quartz tube is also short, and the ability to resist impact is also poor. That is to say, it will be broken when touched, and its radiation ability is also worse than that of the far-infrared heating tube.
Resistance wire heating or stainless steel heating tube, which one is better?
The heating effect of using the resistance wire alone is the worst. The stainless steel heating tube is the iron tube with the resistance wire placed inside the iron tube, filled with magnesium oxide, and coated with far-infrared paint on the outside of the iron tube. This is the best heating element.
Which kind of oven heating tube is better:
The best oven heating element belongs to the far-infrared heater, but the far-infrared heating tube is much more expensive than the above three kinds of electric heating tubes. If the quantity is small and the price is not considered, the far-infrared heating tube can be used.
