What are the pros and cons of quartz tube heating and stainless steel tube heating in electric ovens?
Quartz tube heat is mainly conducted by infrared heat radiation, and air heat conduction is small. The advantage is that the production process is simple, so the cost is lower, and the relative price is lower.
The disadvantage of quartz tube heating is that the metal heating elements such as iron-chromium-aluminum and nickel-chromium wires in the quartz tube are in non-vacuum. The metal heating element will be oxidized when used for a long time, which will increase the resistance and reduce the rated power, which will increase the temperature of the space. It's getting slower and slower.
Stainless steel heats mainly by air heat conduction, and the heat radiation is small. The stainless steel tube heated by heat conduction has the advantage of fast heating, but the disadvantage is that it is not easy to be uniform, but it can locally heat the object. The advantages of stainless steel heating tubes are: better heat resistance, dry burning resistance, more mature technology, and lower cost. The difference between the quality of the stainless steel electric heating tube is mainly the nickel content. Nickel is an excellent corrosion-resistant material. After being combined with chromium in stainless steel, the corrosion resistance and process performance of stainless steel can be improved to some extent.
