The heating element for microwave oven is a metal tube as the shell (iron, stainless steel, copper, etc.), and the spiral electric thermal alloy wire (nickel chromium, iron chromium alloy) is uniformly distributed along the central axis of the tube. The void is filled with the crystalline magnesia with good insulation and thermal conductivity, and the two ends of the tube are sealed with silicone and then processed by other processes. This metal-clad electric heating element can heat air, metal molds and various liquids. The oven heating tube is used to heat the fluid by forced convection. It has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation, long service life and so on.
Now the mainstream steam oven heating tube material on the market is stainless steel. The difference between the quality of stainless steel electric heating pipe material is mainly the difference in nickel content. Nickel is an excellent corrosion resistant material, and the corrosion resistance and process properties of stainless steel can be improved after the combination of chromium in stainless steel. The nickel content of 310S and 840 stainless steel pipes reaches 20%, which is an excellent material with strong acid and alkali resistance and high temperature resistance in heating pipes.

The position of the tubular oven heater is mainly divided into hidden heating tube and bare heating tube:
The hidden oven heating tube can make the inner cavity of the oven more beautiful and reduce the risk of corrosion of the heating tube. However, because the heating tube is hidden under the stainless steel chassis, and the stainless steel chassis can not withstand too high a temperature, resulting in the upper limit of the direct heating temperature at the bottom of the baking time between 150-160 degrees, so there is often a situation that the food is not cooked. And the heating should be carried out through the chassis, the stainless steel chassis needs to be heated first, and the food is heated again, so the time is not naked fast.
Bare grill heating tube refers to the heat pipe directly exposed at the bottom of the inner cavity, although it looks a little unattractive. However, there is no need to pass through any medium, the heating tube directly heats the food, and the cooking efficiency is higher. You may be worried that it is not easy to clean the inner cavity of the steam oven, but the heating tube can be folded up and can be easily cleaned.
