Is the heating tube always red when used in the oven?
Whether the oven heating tube is always red during use depends on the surface temperature of the oven heating tube. The surface temperature depends on the surface load (power) of the heating tube design. When the surface temperature of the electric heating tube is 400 degrees, heating The surface of the tube is red. Therefore, when the electric heating tube is working, the oven is set to 300 degrees, then the surface temperature of the heating tube can reach about 400 degrees. That is to say, whether the oven heating tube is always red during use mainly depends on the surface load design of the oven heating tube and the setting of the working temperature.
Generally, the heating tube in the oven needs to be red.
